Dietary intake and practices in the Hong Kong Chinese population. (1/4907)

OBJECTIVES: To examine dietary intake and practices of the adult Hong Kong Chinese population to provide a basis for future public health recommendations with regard to prevention of certain chronic diseases such as cardiovascular disease, hypertension, and osteoporosis. PARTICIPANTS: Age and sex stratified random sample of the Hong Kong Chinese population aged 25 to 74 years (500 men, 510 women). METHOD: A food frequency method over a one week period was used for nutrient quantification, and a separate questionnaire was used for assessment of dietary habits. Information was obtained by interview. RESULTS: Men had higher intakes of energy and higher nutrient density of vitamin D, monounsaturated fatty acids and cholesterol, but lower nutrient density of protein, many vitamins, calcium, iron, copper, and polyunsaturated fatty acids. There was an age related decrease in energy intake and other nutrients except for vitamin C, sodium, potassium, and percentage of total calorie from carbohydrate, which all increased with age. Approximately 50% of the population had a cholesterol intake of < or = 300 mg; 60% had a fat intake < or = 30% of total energy; and 85% had a percentage of energy from saturated fats < or = 10%; criteria considered desirable for cardiovascular health. Seventy eight per cent of the population had sodium intake values in the range shown to be associated with the age related rise in blood pressure with age. Mean calcium intake was lower than the FAO/WHO recommendations. The awareness of the value of wholemeal bread and polyunsaturated fat spreads was lower in this population compared with that in Australia. There was a marked difference in types of cooking oil compared with Singaporeans, the latter using more coconut/palm/mixed vegetable oils. CONCLUSION: Although the current intake pattern for cardiovascular health for fat, saturated fatty acid, and cholesterol fall within the recommended range for over 50% of the population, follow up surveys to monitor the pattern would be needed. Decreasing salt consumption, increasing calcium intake, and increasing the awareness of the health value of fibre may all be beneficial in the context of chronic disease prevention.  (+info)

Prior protein intake may affect phenylalanine kinetics measured in healthy adult volunteers consuming 1 g protein. kg-1. d-1. (2/4907)

Study of the amino acid metabolism of vulnerable groups, such as pregnant women, children and patients, is needed. Our existing protocol is preceded by 2 d of adaptation to a low 13C formula diet at a protein intake of 1 g. kg-1. d-1 to minimize variations in breath 13CO2 enrichment and protein metabolism. To expand on our potential study populations, a less invasive protocol needs to be developed. We have already established that a stable background 13CO2 enrichment can be achieved on the study day without prior adaptation to the low 13C formula. Therefore, this study investigates phenylalanine kinetics in response to variations in prior protein intake. Healthy adult subjects were each fed nutritionally adequate mixed diets containing 0.8, 1.4 and 2.0 g protein. kg-1. d-1 for 2 d. On d 3, subjects consumed an amino acid-based formula diet containing the equivalent of 1 g protein. kg-1. d-1 hourly for 10 h and primed hourly oral doses of L-[1-13C]phenylalanine for the final 6 h. Phenylalanine kinetics were calculated from plasma-free phenylalanine enrichment and breath 13CO2 excretion. A significant quadratic response of prior protein intake on phenylalanine flux (P = 0.012) and oxidation (P = 0.009) was identified, such that both variables were lower following adaptation to a protein intake of 1.4 g. kg-1. d-1. We conclude that variations in protein intake, between 0.8 and 2.0 g. kg-1. d-1, prior to the study day may affect amino acid kinetics and; therefore, it is prudent to continue to control protein intake prior to an amino acid kinetics study.  (+info)

Lysine deficiency alters diet selection without depressing food intake in rats. (3/4907)

Under states of protein deficiency, the dietary limiting amino acid, rather than protein content, can act as the dietary stimulus to control diet selection. If fact, threonine-deficient rats will alter their diet selection patterns solely on the basis of very small changes (0.009 g/100 g) in the dietary threonine concentration. In these studies, we assessed whether lysine-deficient rats will also alter their diet selection patterns on the basis of small changes in dietary Lys concentration. In all experiments, growing rats were adapted to diets in which the protein fraction (purified amino acids or wheat gluten) was limiting in Lys. They were then given a choice between the adaptation diet (AD) diet and a slightly more deficient diet. Rats that were adapted to a Lys-deficient diet (0.25 g Lys/100 g) selected their AD over diets containing as little as 0.01% less Lys (P < 0.01) within 5 d. To determine how deficient rats must be before they alter their selection patterns, rats were adapted to diets containing various levels of Lys, i.e., 2 levels below the requirement for growth and 2 levels above the requirement for growth, but below the requirement for maximal nitrogen retention. Only rats adapted to diets containing Lys below their requirement for growth selected their AD over a diet containing 0.05% less Lys (P < 0.005). Finally, to determine whether rats will alter their selection to whole protein-based diets, rats were adapted to 25% wheat gluten diets supplemented with 0.03-0.21% Lys. Rats selected the AD over a diet containing as little as 0.09% less supplemental Lys by d 4 of the trial (P < 0.05). We conclude that rats are sensitive to changes as small as 0.01% in dietary Lys concentration, but that sensitivity requires prior adaptation to Lys-deficient diets.  (+info)

Ruminally undegraded intake protein in sheep fed low-quality forage: effect on weight, growth, cell proliferation, and morphology of visceral organs. (4/4907)

To determine the influence of increasing levels of supplemental ruminally undegraded intake protein (UIP) on visceral organ weights, growth, cell proliferation, and morphology, 20 mature ewes of mixed breeding were fed a 6.55% CP grass hay:straw mixture (40:60) and assigned to one of four supplemental treatments. Supplements were control (no supplement) and low, medium, and high levels of UIP. After 42 to 46 d on treatment, ewes were infused i.v. with 5-bromo-2-deoxy-uridine (BrdU, a thymidine analog used to provide an index of the rate of intestinal cell proliferation) and slaughtered 1 h later. Visceral organs were weighed, and subsamples were obtained to evaluate visceral DNA, RNA, and protein contents (frozen samples) as well as intestinal morphology (fixed samples). Final BW; eviscerated BW (EBW); total visceral weight; and liver fresh, dry, and dry fat-free weights were increased (P<.10) in protein-supplemented ewes compared with controls, but were not influenced by increasing levels of UIP. Tissue weights of duodenum, jejunum, ileum, cecum, and colon were not greatly influenced by treatment. There were no differences among treatments in intestinal DNA and protein concentrations and the ratios RNA:DNA and protein:DNA. Jejunal RNA concentration and content was increased (P<.10) in low compared with medium and high treatments. Jejunal RNA content also was decreased (P<.10) in high compared with the medium UIP treatment. Liver RNA and protein contents were increased (P<.10) with protein supplementation. In contrast, contents of RNA, DNA, and protein in duodenum, ileum, cecum, and colon were not influenced by treatment. In addition, neither the rate of intestinal proliferation (BrdU labeling) nor intestinal morphology (crypt depth, villus length, or villus width) were affected by treatment. These data indicate that the influence of protein supplementation on visceral growth involves primarily the liver and not the intestines. These data also indicate that visceral growth, except in jejunum, are not altered by differing levels of UIP supplementation.  (+info)

Fermentation substrate and dilution rate interact to affect microbial growth and efficiency. (5/4907)

The effect of dilution rate (D) on carbohydrate, fibrous and nonfibrous, and protein fermentation by ruminal microorganisms was studied using a single-effluent continuous-culture system. The diets of fibrous carbohydrate, nonfibrous carbohydrate, or protein were formulated with soybean hulls (FC), ground corn (NFC), or isolated soy protein (PR) as the primary ingredient, respectively. Six dilution rates (.025, .050, .075, .10, .15, and .20/h of fermenter volume) were used. Digestibilities of DM, OM, and CP for the three diets and of NDF and ADF for the FC diet decreased (P<.001) as D increased, although the response of the digestibility to D varied with diet. Increasing D resulted in an increase in pH (P<.001) and a decrease (P<.001) in ammonia concentration. Daily volatile fatty acid production increased (quadratic; P<.01) for the FC and NFC diets, but decreased (quadratic; P<.001) for the PR diet. Increasing D quadratically increased (P<.001) the molar percentage of acetate and propionate, but quadratically decreased (P<.001) butyrate and valerate for the FC and NFC diets. For the PR diet, the molar percentage of propionate and valerate increased (quadratic; P<.01), whereas acetate and butyrate decreased (linear; P<.001) in response to increasing D. Molar percentage of isobutyrate and isovalerate decreased (P<.01) with increasing D for all three diets. As D increased, daily microbial N production showed quadratic responses with maximum values achieved at .126, .143, and .187/h D for the FC, NFC, and PR diet, respectively. There was a positive correlation between microbial growth efficiency (MOEFF) and D. A quadratic model fit the data of MOEFF as affected by D, and maximum MOEFF of 37.3, 59.6, and 71.4 g of bacterial N/kg OM truly fermented were calculated to be achieved at .177, .314, and .207/h D for the FC, NFC, and PR diet, respectively. Dilution rate significantly influenced the ruminal microbial fermentation of fibrous and nonfibrous carbohydrates and proteins, and was positively related to microbial yield and growth efficiency. In addition, microbial nitrogen composition, and therefore efficiency, was affected by substrate fermented.  (+info)

Nitrogen retention by lambs fed oscillating dietary protein concentrations. (6/4907)

Nitrogen excreted by beef cattle can be retained in manure or lost by volatilization to the atmosphere or by runoff and percolation into surface or ground water. Increasing the retention of dietary N should decrease environmental losses. To this end, the effects of oscillating concentrations of dietary CP on nutrient retention were determined using lambs fed a 90% concentrate diet. Ten St. Croix lambs (average BW = 27 kg) were used in two 5x5 Latin square experiments. Dietary treatments were as follows: 1) 10% CP, 2) 12.5% CP, 3) 15% CP, 4) 10% and 15% CP diets oscillated at 24-h intervals, and 5) 10% and 15% CP diets oscillated at 48-h intervals. Supplemental N was provided by cottonseed meal in Trial 1 and by a 50:50 (N basis) blend of cottonseed meal and urea in Trial 2. Each period of the Latin square lasted 35 d, with excreta collection the final 8 d. Nitrogen retention increased linearly (P<.01) with increasing N intake in both trials (.77, 1.33, and 1.89 g/d for 10, 12.5, and 15% CP, respectively, in Trial 1; .94, 1.78, and 2.19 g/d for 10, 12.5, and 15% CP, respectively, in Trial 2). Compared with continuously feeding the 12.5% CP diet, oscillating the 10 and 15% CP diets on a 24-h basis did not affect N retention (P>.10) in either trial (1.62 and 1.56 g/d for Trials 1 and 2, respectively). Oscillating dietary CP at 48-h intervals did not affect N retention in Trial 2 (1.82 g/d) but increased (P<.05) N retention by 38% in Trial 1 (1.87 g/d). Phosphorus, K, and Na retention and excretion were not affected by dietary treatments in Trial 1. In Trial 2, P retention increased (linear, P<.05) with increasing dietary CP and was greater (P<.05) in lambs on the 48-h oscillation treatment than in lambs fed the 12.5% CP diet. These results suggest that oscillating the dietary CP concentrations might potentially increase the utilization of N by ruminants fed high-concentrate diets.  (+info)

Hormone-related, muscle-specific changes in protein metabolism and fiber type profile after faba bean intake. (7/4907)

Male growing Wistar rats were fed, over 15 days, isoenergetic (16.72 +/- 0.49 MJ) and isoproteic (11%) diets containing either lactalbumin or raw Vicia faba L. (Vf) as the sole source of protein. Compared with pair-fed controls (PF), soleus muscles of Vf-fed rats showed increased (P < 0.05) synthesis and breakdown rates. In addition, the soleus of Vf-fed rats displayed a decrease (P < 0.05) in type I and an increase (P < 0.01) in type IIc fibers compared with that of PF animals. On the contrary, extensor digitorum longus muscles of both Vf-fed and PF rats showed an increase (P < 0.01) in type I and a reduction (P < 0.05) in type IIb fibers together with a decrease (P < 0.05) in the cross-sectional area of the latter fibers. Vf-fed rats exhibited a significant decrease in serum insulin (P < 0.05) and thyrotropin (P < 0.01) levels, together with an increase in plasma glucagon (P < 0.05) and 3,5,3'-triiodothyronine (P < 0.01) concentrations, compared with the PF group. Both Vf-fed and PF rats experienced an increase in corticosterone concentrations (P < 0.01 vs. control; P < 0.05 vs. PF). The muscle-specific changes in both protein metabolism and fiber type composition may partly depend on the hormonal changes that were observed after Vf intake.  (+info)

Lipoprotein(a) and dietary proteins: casein lowers lipoprotein(a) concentrations as compared with soy protein. (8/4907)

BACKGROUND: Substitution of soy protein for casein in the diet decreases LDL cholesterol and increases HDL cholesterol. How the 2 proteins affect lipoprotein(a) [Lp(a)], an independent risk factor for coronary artery disease, is unknown. OBJECTIVE: We compared the effects of dietary soy protein and casein on plasma Lp(a) concentrations. DESIGN: Nine normolipidemic men were studied initially while consuming their habitual, self-selected diets, and then, in a crossover design, while consuming 2 liquid-formula diets containing either casein or soy protein. The dietary periods lasted 45 d (n = 7) or 33 d (n = 2). Fasting total cholesterol, LDL-cholesterol, HDL-cholesterol, triacylglycerol, and Lp(a) concentrations were measured throughout. RESULTS: After 30 d of each diet, the mean concentration of Lp(a) was not significantly different after the soy-protein and self-selected diets. However, Lp(a) decreased by an average of 50% (P < 0.001) after the casein diet as compared with concentrations after both the soy-protein and self-selected diets. Two weeks after subjects switched from the self-selected to the soy-protein diet, Lp(a) increased by 20% (P = 0.065), but subsequently decreased to baseline. In contrast, the switch to the casein diet did not cause an increase in Lp(a), but instead a continuing decrease in mean concentrations to 65% below baseline (P < 0.0002). Total cholesterol, LDL cholesterol, and HDL cholesterol were significantly lower > or =30 d after both the casein and soy-protein diets than after the self-selected diet (P < 0.001). HDL cholesterol was 11% higher after the soy-protein diet than after the casein diet (P < 0.002), but LDL cholesterol, total cholesterol, and triacylglycerol were not significantly different after the casein and soy-protein diets. CONCLUSION: These findings indicate that soy protein may have an Lp(a)-raising effect, potentially detrimental to its use in antiatherogenic diets.  (+info)

Kidneys produce ammonium to buffer and excrete acids through metabolism of glutamine. Expression of the glutamine transporter Slc38a3 (SNAT3) increases in kidney during metabolic acidosis (MA), suggesting a role during ammoniagenesis. Potassium depletion and high dietary protein intake are known to elevate renal ammonium excretion. In this study, we examined SNAT3, phosphate-dependent glutaminase (PDG), and phosphoenolpyruvate carboxykinase (PEPCK) regulation during a control (0.36%) or low-K(+) (0.02%) diet for 7 or 14 days or a control (20%) or high-protein (50%) diet for 7 days. MA was induced in control and low-K(+) groups by addition of NH(4)Cl. Urinary ammonium excretion increased during MA, after 14-day K(+) restriction alone, and during high protein intake. SNAT3, PDG, and PEPCK mRNA abundance were elevated during MA and after 14-day K(+) restriction but not during high protein intake. SNAT3 protein abundance was enhanced during MA (both control and low K(+)), after 14-day low-K(+) ...
BACKGROUND: High sugar and fat intakes are known to increase intrahepatocellular lipids (IHCLs) and to cause insulin resistance. High protein intake may facilitate weight loss and improve glucose homeostasis in insulin-resistant patients, but its effects on IHCLs remain unknown. OBJECTIVE: The aim was to assess the effect of high protein intake on high-fat diet-induced IHCL accumulation and insulin sensitivity in healthy young men. DESIGN: Ten volunteers were studied in a crossover design after 4 d of either a hypercaloric high-fat (HF) diet; a hypercaloric high-fat, high-protein (HFHP) diet; or a control, isocaloric (control) diet. IHCLs were measured by (1)H-magnetic resonance spectroscopy, fasting metabolism was measured by indirect calorimetry, insulin sensitivity was measured by hyperinsulinemic-euglycemic clamp, and plasma concentrations were measured by enzyme-linked immunosorbent assay and gas chromatography-mass spectrometry; expression of key lipogenic genes was assessed in ...

AU - Keane, William F.. AU - Daniels, Frank. PY - 1990/5. Y1 - 1990/5. N2 - It is unclear whether glomerular hemodynumic changes always accompany alterations in dietary protein, and whether nonhemodynamic factors associated with a high protein intake can influence glomerular injury. In the present study, uninephrectomized (UNx) male rats were fed either standard (20%) or high (40%) protein diets. Body growth was comparable in the two diet groups. At 30 weeks of age, UNx rats fed high protein had increased albuminuria (36.7 ± 12.6 mg/24 hr), compared to UNx rats fed standard protein (10.2 ± 6.2 mg/24 hr; P , 0.05). The incidence of focal glomerulosclerosis (FGS) at 36 weeks was markedly increased in the high protein rats (19.0 ± 7.7%), compared to the standard protein rats (3.2 ± 2.0%; P , 0.05). ...

There is increasing public pressure on intensive dairy operations to reduce nitrogen (N) excretion into the environment, which can be achieved by adopting on-farm feeding practices that enhance the efficiency of N utilization. One such feeding strategy that has received attention is feeding diets with oscillating crude protein (CP) concentrations, and studies with finishing beef cattle and growing sheep have reported improvements in N retention when oscillating CP diets are fed compared to static CP diets. This experiment was conducted to determine: 1) the optimum frequency of oscillating dietary CP concentration (i.e., 24, 48, or 72 h); 2) the effects of feeding oscillating CP diets on feed intake, milk production and milk composition in dairy cows; and 3) the effects of feeding oscillating CP diets on ruminal fermentation characteristics (NH3, SCFA and pH), microbial protein synthesis, ruminal outflow of nutrients and N balance in dairy cows. Eight Holstein cows (714 ± 36 kg body weight; 114 ...
The primary aim is to examine the effect of a high protein intake (from soy or whey protein) on weightmaintenance after weight loss in a group of predisposed (severe) obese persons. Furthermore, to examine short-term and long-term effect of a high protein intake on appetite regulation and diet induced thermogenese (DIT). Finally to examine the effect of calcium on weightmaintence, bloodlipid profilen, appetite regulation and DIT.. The study is a parallel RCT with a weight loss (WL) period (8 weeks on very low calorie diet) and a weightmaintence (WM) period (24 weeks daily intake of supplement). 200 overweight/obese subjects will be enrolled into the study and randomized to placebo (maltodextrin), soy protein, whey protein or calcium enriched whey protein supplement. At baseline (week 0), after the WL period (week 8) and after WM period (week 24) body weight and composition will be measured and blood samples will be collected. Meal test will be performed at week 0 and 24 (examining both appetite ...
New Australian research suggests that overweight and obese people can increase the amount of fat they burn by simply consuming higher-protein meals.. While previous studies have shown that thin people are more efficient fat burners than those who are overweight, the current research examined whether the protein composition of meals influenced that weight-related disparity.. The researchers found that overweight men and women burned more fat after consuming high-protein meals than after eating lower-protein meals. In other words, the additional protein seemed to compensate for the fat-burning deficit observed in overweight people.. Our research suggests that people with higher body fat burn fat better after a high-protein meal than people with lower levels of body fat, lead researcher Dr. Marijka Batterham of Australias University of Wollongong told Reuters.. Multiple studies have also suggested that high-protein diets may help people lose weight, in part because protein may suppress appetite ...

1. Studies were carried out on six normal male subjects to determine the short-term effect of increasing the dietary consumption of animal protein on the urinary risk factors for stone-formation, namely, volume, pH, calcium, oxalate, uric acid and glycosaminoglycans.. 2. An increase of 34 g/day of animal protein in the diet significantly increased urinary calcium (23%) and oxalate (24%). Total urinary nitrogen increased by an average of 368 mmol/day. The accompanying increase in dietary purine (11 mmol of purine nitrogen/day) caused a 48% increase in the excretion of uric acid.. 3. The overall relative probability of forming stones, calculated from a combination of the risk factors, was markedly increased (250%) throughout the period of high animal protein ingestion. ...
In the study to investigate whether addition of protein may improve weight maintenance by preventing or limiting weight regain after weight loss of 5-10% in moderately obese subjects, a 20% higher protein intake, that is, 18% of energy vs 15% of energy during weight maintenance after weight loss, resulted in a 50% lower body weight regain, only consisting of fat-free mass, and related to increased satiety and decreased energy efficiency.(1 ...
Considerable debate has taken place over the safety and validity of increased protein intakes for both weight control and muscle synthesis. The advice to consume diets high in protein by some health professionals, media and popular diet books is given despite a lack of scientific data on the safety of increasing protein consumption. The key issues are the rate at which the gastrointestinal tract can absorb amino acids from dietary proteins (1.3 to 10 g/h) and the livers capacity to deaminate proteins and produce urea for excretion of excess nitrogen. The accepted level of protein requirement of 0.8g · kg−1 · d−1 is based on structural requirements and ignores the use of protein for energy metabolism. High protein diets on the other hand advocate excessive levels of protein intake on the order of 200 to 400 g/d, which can equate to levels of approximately 5 g · kg−1 · d−1, which may exceed the livers capacity to convert excess nitrogen to urea. Dangers of excessive protein, defined ...

Barenys, M.; Recasens, M.A.; Martí-Henneberg, C.; Salas-Salvadó, J., 1993: Effect of exercise and protein intake on energy expenditure in adolescents
(HealthDay)-High total and animal protein intake correlates with increased incidence of type 2 diabetes, according to a study published online April 10 in Diabetes Care.
Inadequate dietary intake and prolonged undernourishment can lead to short term and long term consequences, which can deplete financial, physical, and social capital, further exacerbating the cycle of undernutrition, poverty, and unhealthy household environment that most food-insecure families already have. Children are a particular focus of interest because of the formative impact nutrition can have on development. Previous research establishes the particular importance of protein consumption in normal childhood growth. This paper seeks to explore dietary protein consumption patterns in countries in Southeast Asia with high rates of stunting, a cumulative indicator of chronic malnutrition - Indonesia, Philippines, Vietnam, Myanmar, and Cambodia - using international health databases. First, it examines the current protein intake level compared to recommended standards for children under five years old. Second, it examines the sources of protein to evaluate the quality of the protein consumption profile
There is a great deal of controversy as to whether higher protein intake improves or worsens insulin sensitivity in humans. The purpose of the study was to determine the influence of a short-term elevation in dietary protein on hepatic and peripheral insulin sensitivity in twelve older subjects (51-70 yrs) with metabolic syndrome. Individuals were randomly assigned to one of the dietary groups: recommended protein intake (RPI, 10% of daily calorie intake) or elevated protein intake (EPI, 20% of daily calorie intake) for 4 weeks. Prior to and immediately following the dietary intervention, subjects were studied with primed continuous infusion of [6,6-2H2]glucose and [1-13C]glucose dissolved in drink during the dual tracer oral glucose tolerance test (DT OGTT) to determine hepatic and peripheral insulin sensitivity. Plasma lipids were measured pre- and post-dietary intervention. In both intervention groups: 1) hepatic insulin sensitivity as assessed by the endogenous glucose rate of appearance (glucose Ra

Considering the limited knowledge on the effects of dietary amino acid intake on dysglycemia, we assessed the possible association of dietary protein and amino acid patterns with the risk of pre-diabetes in a prospective population-based study. Participants without diabetes and pre-diabetes (n = 1878) were recruited from the Tehran Lipid and Glucose Study and were followed for a mean of 5.8 years. Their dietary protein and amino acid intakes were assessed at baseline (2006-2008); demographic, lifestyle, and biochemical variables were evaluated at baseline and in follow-up examinations. Pre-diabetes was defined according to the American Diabetes Association criteria. Multivariate Cox proportional hazard regression models, adjusted for potential confounders, were used to estimate the risk of pre-diabetes across tertiles of dietary protein and amino acid pattern scores. The mean age of the participants (44.9% men) was 38.3 ± 12.7 years at baseline. Three major amino acid patterns were characterized: (1)
11 As with all diets, misconceptions have arisen with this diet. Many individuals adhering to a low-fat diet incorrectly believe that only fat calories cause weight gain, leading to an overindulgence of grains and starches. Increased caloric intake, no matter where the calories come from, can result in weight gain 11 (Table 2; Sidebar: The Old-Fashioned Solution Calorie Counting). Other Dieting Trends Other popular diets include a high-calcium diet, especially from dairy products, to promote weight loss. Although calcium intake has obvious health benefits, its role in weight loss needs further clinical investigation.2 Advocates of high-protein diets suggest that increased protein correlates with increased satiety and increased thermic effect from food. Again, little evidence exists to support this theory, and the effects of high protein intake on renal function and calcium balance are unknown but are worthy of concern.2 Whereas a definite link has yet to be established, epidemiologic data show a ...

Protein toxicity is the effect of the buildup of protein metabolic waste compounds due to insufficient kidney function. It can occur in people with preexisting kidney disease, or those who have lost kidney function due to age. Protein toxicity occurs when the body is unable to get rid of the potentially toxic wastes that are generated as a result of protein metabolism, it may be also caused by kidney failure. Protein toxicity occurs when an individual with impaired kidney function consumes protein rich diet. Specifically proteins from animal sources that are rapidly absorbed into the blood stream and are rapidly metabolized causing the release of high concentration of toxic nitrogenous waste material A high protein diet is a health concern for those suffering from renal disease. The main concern is that a high protein intake may promote further renal damage that can lead to protein toxicity. The physiological changes induced by an increased protein intake, such as an increased glomerular ...

Before getting into this, I want to make something clear. Research does show that high-protein diets can be harmful for people who already have chronic kidney disease, and low-to-moderate protein diets are generally advisable for these patients.. However, just because a low-protein diet can be therapeutic for those with kidney disease, doesnt mean a high-protein diet causes kidney disease in the first place. (This is the same distinction I made when critiquing Dr. Perlmutters broad recommendation for a low-carb diet to prevent neurological disorders.) What Im addressing here is the notion that high-protein diets cause kidney disease in healthy people-which is not, as youll find out, supported by research.. Since one of the main biological roles of the kidney is to metabolize and excrete nitrogen byproducts from protein digestion, many people believe that eating more protein will strain the kidneys. This is similar to the argument made against acid-forming diets. There is an upper limit to ...
A total of 180 pigs (90 barrows and 90 gilts, average initial weight of 148 lb) were used in a 67-day experiment to determine the effects of excess dietary crude protein (CP) on growth performance and carcass measurements in finishing pigs. The pigs were sorted by ancestry and blocked by weight with 12 pigs per pen and five pens per treatment. Treatments were corn-soybean meal-based diets formulated to 15.3 and 18.3 per cent CP and a corn-soybean-DDGS-based diet formulated to 18.3 per cent CP. Feed and water were consumed on an ad libitum basis until the pigs were slaughtered (average final weight of 282 lb) at a commercial abattoir ...
A total of ten experimental diets with protein concentrations ranging from 154 to 400 g/kg and two lipid levels (46 and 85 g/kg) with identical energy densities were offered to 240 male Ross 308 broilers from 7 to 28 d post-hatch. Growth performance was monitored and nutrient utilisation (apparent metabolisable energy (AME), N-corrected AME (AMEn), AME daily intake, AME:gross energy ratios, N retention) was determined. The weight gain response of broiler chickens to dietary protein concentrations in diets containing high and low lipid levels was diverse, with the relevant quadratic regressions being significantly different (P,0·05). With low lipid levels, the predicted maximum weight gain of 1809 g/bird equated to 342 g/kg dietary protein, whereas, for high lipid levels the predicted maximum weight gain of 1694 g/bird equated to 281 g/kg dietary protein. AME was linearly correlated with dietary protein concentration but regressions in diets with different lipid content were not significantly ...
Summary:Dietary protein intake and renal functionRecent trends in weight loss diets have led to a substantial increase in protein intake by individuals. As a result,
Malnutrition at the initiation of dialysis is a strong predictor of subsequent increased mortality on dialysis. Few studies have documented the relationship between the progression of renal failure and spontaneous dietary protein intake (DPI) and other indices of malnutrition. In this prospective study, renal function was sequentially measured by creatinine clearance (CrCl) and DPI by 24-h urine collection; simultaneously, multiple sequential biochemical nutritional indices, including serum albumin, transferrin, prealbumin, and insulin-like growth factor-I (IGF-I) concentrations, were measured. The study involved 90 patients (46 men and 44 women) with chronic renal failure (CRF) of various causes monitored in an outpatient clinic. Dietary interventions were minimal. The mean duration of follow-up was 16.5 +/- 11.8 months. The results show that the mean (+/- SD) DPI was 1.01 +/- 0.21 g/kg per day for patients with CrCl over 50 mL/min and decreased to 0.85 +/- 0.23 g/kg per day for patients with ...

Resistance trainers continue to receive mixed messages about the safety of purposely seeking ample dietary protein in their quest for stimulating protein synthesis, improving performance, or maintaining health. Despite proteins lay popularity and the routinely high intakes exhibited by strength athletes, liberal and purposeful protein consumption is often maligned by experts. University textbooks, instructors, and various forms of literature from personal training groups and athletic organizations continue to use dissuasive language surrounding dietary protein. Due to the widely known health benefits of dietary protein and a growing body of evidence on its safety profile, this is unfortunate. In response, researchers have critiqued unfounded educational messages. As a recent summarizing example, the International Society of Sports Nutrition (ISSN) Position Stand: Protein and Exercise reviewed general literature on renal and bone health. The concluding remark that Concerns that protein intake within
An increase in dietary protein intake has been shown to improve weight loss maintenance in the DIOGenes trial. Here, we analysed whether the source of the dietary proteins influenced changes in body weight, body composition, and cardiometabolic risk factors during the weight maintenance period while following an energy-restricted diet. 489 overweight or obese participants of the DIOGenes trial from eight European countries were included. They successfully lost >8% of body weight and subsequently completed a six month weight maintenance period, in which they consumed an ad libitum diet varying in protein content and glycemic index. Dietary intake was estimated from three-day food diaries. A higher plant protein intake with a proportional decrease in animal protein intake did not affect body weight maintenance or cardiometabolic risk factors. A higher plant protein intake from non-cereal products instead of cereal products was associated with benefits for body weight maintenance and blood pressure.
OBJECTIVE: The long-term association between dietary protein and type 2 diabetes incidence is uncertain. We aimed to investigate the association between total, animal, and plant protein intake and the incidence of type 2 diabetes. RESEARCH DESIGN AND METHODS: The prospective European Prospective Investigation into Cancer and Nutrition (EPIC)-InterAct case-cohort study consists of 12,403 incident type 2 diabetes cases and a stratified subcohort of 16,154 individuals from eight European countries, with an average follow-up time of 12.0 years. Pooled country-specific hazard ratios (HRs) and 95% CI of prentice-weighted Cox regression analyses were used to estimate type 2 diabetes incidence according to protein intake. RESULTS: After adjustment for important diabetes risk factors and dietary factors, the incidence of type 2 diabetes was higher in those with high intake of total protein (per 10 g: HR 1.06 [95% CI 1.02-1.09], P(trend) | 0.001) and animal protein (per 10 g: 1.05 [1.02-1.08], P(trend) = 0.001).
Leucine kinetic and nitrogen balance (NBAL) methods were used to determine the dietary protein requirements of strength athletes (SA) compared with sedentary subjects (S). Individual subjects were randomly assigned to one of three protein intakes: low protein (LP) = 0.86 g, moderate protein (MP) = 1.40 g, or high protein (HP) = 2.40 g for 13 days for each dietary treatment. NBAL was measured and whole body protein synthesis (WBPS) and leucine oxidation were determined from L-[1-13C]leucine turnover. NBAL data were used to determine that the protein intake for zero NBAL for S was 0.69 and for SA was 1.41 A suggested recommended intake for S was 0.89 and for SA was 1.76 For SA, the LP diet did not provide adequate protein and resulted in an accommodated state (decreased WBPS vs. MP and HP), and the MP diet resulted in a state of adaptation [increase in WBPS (vs. LP) and no change in ...
Three levels of dietary crude protein (8.6, 11.4, and 17.2) were fed to 24 pony mares to determine the effects on the estrous cycle, conception rate, and serum progesterone concentrations. Mares were allotted into three treatment groups designated as low protein (LP), medium protein (MP), and high protein (HP). Following estrous synchronization with progesterone and prostaglandin F₂∞, dietary protein at the levels investigated, did not affect (P ,.05) estrous synchronization, length of estrus, the number of days to ovulation, or the number of inseminations per conception. Conception rate following two cycles tended (P, .05) to be higher in the MP (87%) group than the LP (50%) or HP {57%) fed groups. Serum progesterone concentrations were affected (P ,.05) by diet with levels of 6.5±.8, 7.9±.8, and 10.3±.8 ng/ml progesterone (least squares means±SE) in the LP, MP, and HP fed groups respectively. Serum progesterone on days 4, 8, 12, and 16 post-ovulation tended (P =.12) to be higher in ...
High-protein diets typically restrictive in carbohydrates have been the foundation of many fad diets. Often in addition to large amounts of protein, these diets are typically restrictive or even eliminate entire food groups. Although eliminating or severely restricting food groups may cause some weight loss, often these diets are not adequate in providing all the essential phytonutrients, vitamins, minerals, trace minerals, fiber and antioxidants that your body needs.. The Recommended Dietary Allowances (RDAs) for protein needs are set at a minimum of 0.8 g/kg body weight, or about 0.4 g/lb, but many high-protein diets aim for 1.2 to 1.4 g/kg. When determining your protein needs, be sure to calculate it off your body weight, not the percentage of the calories that you aim to consume in a day. High-protein diets typically are about 25% to 30% protein, 40% to 45% carbohydrates, and no more than 30% fat.. The reason why high-protein continues to be a popular aspect of most diets is because eating ...
The body cannot store protein in the same way it can store fat or glycogen and therefore it is necessary to regularly provide the body with dietary protein. There optimal amount of protein to be consumed daily is a contested area between dietitians, sport scientists and medical specialists. For highly active individuals, advice tends to recommend anything between 1-2g per kg of body weight per day. The most commonly advised figure is 1.8g per kg body weight, meaning a reasonable guide is between 99-110g per day for a 55kg dancer. Again it comes down to what works for you, if you feel better, stronger, healthier on around 90g a day, go with that. If you are happier at 110g and up, then up your protein intake to that level. Excess protein intake had previously been linked to kidney problems, however recent studies have shown that high protein intake causes no negative effects on individuals who do not have pre-existing kidney conditions ...

High protein intake can not relieve proteinuria, but can aggravate the progression of the disease. Therefore, it is very essential to limit protein intake. From stage 1 Chronic Kidney Disease to stage 4, the protein intake should be restricted to 0.6~0.75g/kg per body weight. If the patients are on hemodialysis, they should keep the protein intake within 1.2 g/kg per body weight. For the patients on peritoneal dialysis, they are recommended to keep the 1.2~1.3g/kg per body weight ...
View Poster. INTRODUCTION. The impact of dietary protein intake on urinary oxalate has not been clearly delineated. Potential reasons include inaccurate dietary assessment of oxalate, calcium, and vitamin C, as well as lack of control for the amount and source of protein. This study will be the first to use the NDSR to obtain a precise dietary assessment of these factors on self-selected rather than controlled diets. The objective of this study is to evaluate the impact of the amount and source of protein intake on urinary oxalate for patients with recent urolithiasis using the NDSR.. METHODS. We prospectively recruited patients from a single institution who either passed or underwent treatment for a calcium oxalate stone within 6 months and were subsequently referred for a complete metabolic work-up. Patients with metabolic predispositions to stone formation or taking medications that may impact urine parameters were excluded. Total dietary intake was obtained using a 3 day food record and 24 ...
The roles of different dietary proteins in the aetiology of type 2 diabetes (T2D) remain unclear. We investigated the associations of dietary proteins with the risk of incident T2D in Finnish men from the prospective Kuopio Ischaemic Heart Disease Risk Factor Study. The study included 2332 men aged 42-60 years at the baseline examinations in 1984-1989. Protein intakes were calculated from 4-d dietary records. Incident T2D was determined by self-administered questionnaires, fasting blood glucose measurements, 2-h oral glucose tolerance tests, and with national registers. The multivariable-adjusted risk of T2D on the basis of protein intakes was compared by the Cox proportional hazard ratios (HR). During the mean follow-up of 19·3 years, 432 incident T2D cases were identified. Total, animal, meat or dairy product protein intakes were not associated with risk of T2D when the potential confounders were accounted for. Plant (multivariable-adjusted extreme-quartile HR 0·65; 95 % CI 0·42, 1·00; P ...
Influence of feeding a high plant protein diet on growth and nutrient utilization to combined all-fish growth-hormone transgenic diploid and triploid Atlantic salmon (Salmo salar L.)
High-quality sources of protein for the formulation of feeds of carnivorous fish species such as Atlantic salmon are currently being sought. In an earlier screening trial we evaluated for the first time in Atlantic salmon (Salmo salar) the applicability of air-classified faba bean (Vicia faba) protein concentrate (BPC) inclusions in combination with soy protein concentrate (SPC) and fishmeal (FM) using parr as a model. Based on the results in parr in freshwater, the present study tested the hypothesis that BPC can effectively replace SPC and/or FM as a dietary protein source in post-smolt Atlantic salmon in seawater. The trial was designed to test nine different combinations of BPC, SPC and FM around the ideal mixture proportions modelled from data on parr (20% BPC, 46% SPC and 34% FM as percent of the total dietary protein). Somatic, physiological, biochemical and molecular parameters were assessed to determine fish performance. On average, fish grew from ~1.28kg to 2.80kg over the course of ...
High dietary protein can reduce fat deposition in animal subcutaneous adipose tissue, but little is known about the mechanism. Sixty Wujin pigs of about 15 kg weight were fed either high protein (HP: 18%) or low protein (LP: 14%) diets, and slaughtered at body weights of 30, 60 or 100 kg. Bloods were collected to measure serum parameters. Subcutaneous adipose tissues were sampled for determination of adipocyte size, protein content, lipid metabolism-related gene expression, and enzyme activities. HP significantly reduced adipocyte size, fat meat percentage and backfat thickness, but significantly increased daily gain, lean meat percentage and loin eye area at 60 and 100 kg. Serum free fatty acid and triglyceride concentrations in the HP group were significantly higher than in the LP group. Serum glucose and insulin concentrations were not significantly affected by dietary protein at any body weight. HP significantly reduced gene expression of acetyl CoA carboxylase (ACC), fatty acid synthase (FAS) and
TY - JOUR. T1 - The measurement and interpretation of dietary protein distribution during a rugby preseason. AU - MacKenzie, Kristen. AU - Slater, Gary. AU - King, Neil. AU - Byrne, Nuala. PY - 2015/8/1. Y1 - 2015/8/1. N2 - Evidence suggests that increasing protein distribution may be desirable to promote muscle protein synthesis (MPS) in combination with resistance exercise. However, there is a threshold above which additional protein consumption has limited benefit for MPS and may promote protein loss due to increased oxidation. This study aimed to measure daily protein intake and protein distribution in a cohort of rugby players. Twenty-five developing elite rugby union athletes (20.5 ± 2.3 years, 100.2 ± 13.3 kg, 184.4 ± 7.4 cm) were assessed at the start and end of a rugby preseason. Using a 7-day food diary the reported daily protein intake was 2.2 ± 0.7 g·kg·day-1 which exceeds daily recommendations. The reported carbohydrate intake was 3.6 ± 1.3 g·kg·day-1 which may reflect a ...
The Western meat-rich diet is both high in protein and fat. Although the hazardous effect of a high fat diet (HFD) upon liver structure and function is well recognized, whether the co-presence of high protein intake contributes to, or protects against, HF-induced hepatic injury remains unclear. Increased intake of branched chain amino acids (BCAA, essential amino acids compromising 20% of total protein intake) reduces body weight. However, elevated circulating BCAA is associated with non-alcoholic fatty liver disease and injury. The mechanisms responsible for this quandary remain unknown; the role of BCAA in HF-induced liver injury is unclear. Utilizing HFD or HFD+BCAA models, we demonstrated BCAA supplementation attenuated HFD-induced weight gain, decreased fat mass, activated mammalian target of rapamycin (mTOR), inhibited hepatic lipogenic enzymes, and reduced hepatic triglyceride content. However, BCAA caused significant hepatic damage in HFD mice, evidenced by exacerbated hepatic oxidative stress,
To exploit the fact that cancer cells rely more heavily on glycolysis than normal cells, we designed low CHO, high protein diets to see if we could limit BG and tumor growth. In designing our diets, we wanted to avoid NCKDs because of the difficulty in achieving long-term compliance with no CHO diets in potential future human studies (27) and because Masko and colleagues recently reported that a 10% or 20% CHO diet slows tumor growth as effectively as NCKDs (27). Following early studies with 8% CHO diets, using 10% and 15% CHO, high protein diets in which 70% of the CHO was in the form of amylose, we found that, compared with a Western diet, they were indeed capable of reducing BG, insulin, and lactate levels and, importantly, in slowing the growth of implanted murine and human tumors, with little or no effects on mouse weight.. We assessed the effects of our low CHO diets in both murine tumor-bearing immunocompetent mice and human tumor-bearing immunocompromised mice, because immune status has ...
Background: It has been shown that dietary protein supplementation during lactation boosts immunity in Nippostrongylus brasiliensis-infected periparturient rats. It is not known whether body protein reserves accumulated during gestation have a similar effect during lactation. Objective: This study aimed to quantify the impact of body protein reserves and dietary protein supplementation on maternal performances and immune responses to N. brasiliensis during lactation. Methods: Multiparous female Sprague-Dawley rats were given a primary infection of N. brasiliensis prior to mating and restrictedly fed either 60 g (Lge) or 210 g (Hge) crude protein (CP) per kg dry matter (DM) until parturition. Parturition onwards, dams were restrictedly fed either 100 g (Lla) or 300 g (Hla) CP per kg DM, generating 4 different dietary treatments. A subset of rats was sampled before parturition; post-parturition, dams were secondary infected with N. brasiliensis and samples were collected at day 5 and 11 post ...
A common criticism of low-carbohydrate diets is the effect of excessive protein intake on bone health and renal function. Reddy et al.19 reported that protein intake of 164-170 g on a 6-week VLCKD increased net acid load, urinary calcium losses, and risk of kidney stones. An earlier review20 of several studies of high-protein diets demonstrated that increasing consumption of alkaline foods (i.e., fruits and vegetables) resulted in a significant decrease in net acid excretion and calciuria along with increased bone deposition. Carter et al.21 found no difference in bone turnover between subjects following a VLCKD and those on a control diet after 3 months. Recent research22 suggests that protein intake of 120 g/day does not adversely affect kidney health in people with normal renal function. There is some evidence that carbohydrate restriction coupled with moderate protein intake may even benefit people with kidney disease and diabetes.23. Because cardiovascular events and stroke are the primary ...
Providing of insufficient nutrients limits the potential growth of pig, while feeding of excessive nutrients increases the economic loss and causes environment pollution. For these reasons, phase feeding had been introduced in swine farm for improving animal production. This experiment was conducted to evaluate the effects of dietary energy levels and phase feeding by protein levels on growth performance, blood profiles and carcass characteristics in growing-finishing pigs. A total of 128 growing pigs ([Yorkshire × Landrace] × Duroc), averaging 26.62 ± 3.07 kg body weight, were assigned in a 2 × 4 factorial arrangement with 4 pigs per pen. The first factor was two dietary energy level (3,265 kcal of ME/kg or 3,365 kcal of ME/kg), and the second factor was four different levels of dietary protein by phase feeding (1growing(G)-2finishing(F) phases, 2G-2F phases, 2G-3F phases and 2G-3F phases with low CP requirement). In feeding trial, there was no significant difference in growth performance. The BUN

Researchers at USC have announced that a protein-restricted diet appears to improve memory and slow the advance of Alzheimers disease in laboratory mice.. For their research, the scientists placed mice with advanced stages of the dementia on a low-protein diet with amino acid supplements every other week for four months. The researchers then ran the mice through mazes and found that those on the low protein diet had improved cognitive ability compared to a control group of mice that ate a higher-protein diet. The mice on the low-protein diets also showed lower levels of the growth hormone IGF-1 - which has been associated with aging and disease in mice and several diseases in older humans.. Whats more, the mice on the protein-restricted diet also showed lower levels of the defective protein known to accumulate in the brains of those diagnosed with Alzheimers and other dementias.. The researchers say their future studies will look at whether low-protein diets have the same ability to slow ...

Each day we are bombarded with new data. My goal is to share a breakdown of what I have discovered and read this past month. There is a little something for everyone here. How do I choose which articles to share? Is it clinically relevant? Does the story share something new or raise an interesting question? Most studies have some internal flaw that can be poked and while I try to only share those having high quality, my number one goals is to share something unique, progressive or surprising.. Published research:. In the recent release of The American Journal of Clinical Nutrition there is a good article supporting the benefits of a high-protein breakfast. Data reveals that a high-protein diet alters ghrelin and peptide YY concentrations subsequently leading to decreased appetite and also curbed late night snacking. Is this study perfect - no. But it is pretty darn good - Yes. I have been blogging on this topic for sometime. Where, when and why did the public begin thinking high protein intake ...

In this study, high total and animal protein intake, but not vegetable protein intake, was associated with increased diabetes risk. This relation was not explained by specific protein sources such as meat or by weight change during follow-up but was attenuated after adjustment for baseline adiposity measures. Consuming 5 energy % from protein at the expense of 5 energy % from carbohydrate or fat increased diabetes risk by ∼30%.. Some aspects of the study need to be addressed. First, although we corrected for all possible available confounders, we cannot exclude unknown or unmeasured confounding. Second, the presence of diabetes goes often undetected and may be preclinical up to 9-12 years (21). Individuals with undetected diabetes may have been misclassified as nondiabetic individuals, resulting in attenuated associations. Strengths of our study include its prospective design, large sample size, and long follow-up. Use of validated cases of diabetes minimized the presence of false-positive ...
Inadequate animal protein intake is widely orchestrated among Nigerians especially Ogun State indigenes. This led to investigating other sources of animal protein in the rural and suburban areas of the state that could bridge inadequate supply from the conventional sources of animal protein. Structured questionnaires were administered in each of the then twelve local governments of the state to collect information on other sources of animal protein. The study showed that a wide range of animal species - mammals, aves, reptiles, amphibian, pisces, gastropods, insects and crustaceans are widely, though infrequently, consumed in virtually all local governments of Ogun State. But while a few are readily available, many are seasonal. Therefore, a concerted effort by the state governments and well meaning individuals to improve production of these animals especially in the local governments where they abound could make them a ready source of supplementary animal protein for the indigenes ...
BACKGROUND: Increased physical activity and dietary protein intake are promising interventions to prevent or treat the age-related decline in physical performance in older adults. There are well-controlled exercise as well as dietary intervention studies that show beneficial effects on physical performance in older adults. In practice, however, weekly group based exercise or nutritional programs may not be as effective. To optimise these exercise programs for community dwelling older adults, a digitally supported and personalised home-based exercise training program has been designed aiming to improve physical performance in older adults. In addition, a protein intervention in combination with the training program may further improve physical performance in older adults. METHODS: The VITAMIN study will be a cluster randomised controlled trial with three parallel arms. In total, 240 community dwelling older adults (≥ 55 years) participating in weekly group exercise are randomly allocated into: ...
Fouque and colleagues review of 6 randomized trials suggests that the prescription of low-protein diets to patients with chronic renal failure can prolong the course of the disease and delay the onset of dialysis. Locatelli and colleagues (1), however, the authors of the largest of these studies, concluded that low-protein diets were of marginal benefit and probably not worth the sacrifice and negative effect on quality of life. The clinical course of the patient with chronic renal disease does not end with dialysis but continues after dialysis and transplantation. The major predictors of success on dialysis are adequacy of dialysis and the nutritional status of the patient as measured by serum albumin, serum creatinine, and protein catabolic rate (a measure of dietary protein intake) (2). Current studies do not address the long-term nutritional implications of low-protein diets, nor do they delineate the degree of protein restriction that prolongs the course of chronic renal failure but ...

When the gut tastes phenylalanine (PHE), leucine (LEU), glutamate (GLUT) and tryptophane (TRP), satiety ensues (Daly. 2012) -- In their most recent paper Christin Daly et al. report on the cholecystokinin (CCK) release in the gut. According to the scientists from the University of Liverpool (UK) and the Kyushu University (Japan), the effect is mediated by interactions with the gastrointestinal bitter taste receptors. Since CCK inhibits food intake and reduces appetite, this provides another mechanistic explanation for the satiety promoting effects of high protein intakes. The effects was observed only for the L- and not the D-amino acids ...
A study out of the University of Illinois supports recent research touting the effects of a high-protein, low-carbohydrate diet plus exercise as the most effective regimen for achieving weight loss. This is one of the few investigations that have considered the role exercise plays in weight loss and altering body composition. The study team randomly assigned 48 women ages 40 to 56 to 1 of 4 regimens: a high-protein diet; a high-protein diet plus exercise; a high-carb diet; or a high-carb diet plus exercise. All diets were nutritionally sound, as the women consumed recommended amounts of fruits, vegetables, and dairy. Those in the exercise groups walked 30 minutes a day 5 times a week and included resistance/weight training.

Quackery From the British Dietetic Association and BBC Newsbeat on High Protein Intakes In an area as nebulous and vital as nutrition, its perfectly natural th
the number and time of protein intake.. According to the current recommendations of nutritionists, an adult should consume 0.8 gram of protein per kilogram of their weight, approximately 62 grams and weighs 77 kg. the Elderly, according to some, needs to consume 0.4 g/kg protein for each meal (31 g 3 times a day with the weight of 77 kg). This is a much larger protein than the recommended dietary recommendations. Researchers from the Centre for translational research in aging and longevity Institute on aging at the University of Arkansas conducted an experiment to find out whether greater daily protein intake to greater net protein synthesis in the elderly. They also considered the time of protein consumption, the difference in the synthesis process in which cells make more pure protein.. For the study, we selected 20 healthy people aged 52-75 years who were divided into 4 groups randomly. Two groups were consuming the recommended 0.8 g/kg of protein ...

The requirements for energy and protein of an individual are defined in the following terms:. Energy. The energy requirement of an individual is the level of energy intake from food that will balance energy expenditure when the individual has a body size and composition, and level of physical activity, consistent with long-term good health; and that will allow for the maintenance of economically necessary and socially desirable physical activity. In children and pregnant or lactating women the energy requirement includes the energy needs associated with the deposition of tissues or the secretion of milk at rates consistent with good health.. Protein. The protein requirement of an individual is defined as the lowest level of dietary protein intake that will balance the losses of nitrogen from the body in persons maintaining energy balance at modest levels of physical activity. In children and pregnant or lactating women, the protein requirement is taken to include the needs associated with the ...

Dietary protein dilution (DPD) promotes metabolic-remodelling and -health but the precise nutritional components driving this response remain elusive. Here, by mimicking amino acid (AA) supply from a casein-based diet, we demonstrate that restriction of dietary essential AA (EAA), but not non-EAA, drives the systemic metabolic response to total AA deprivation; independent from dietary carbohydrate supply. Furthermore, systemic deprivation of threonine and tryptophan, independent of total AA supply, are both adequate and necessary to confer the systemic metabolic response to both diet, and genetic AA-transport loss, driven AA restriction. Dietary threonine restriction (DTR) retards the development of obesity-associated metabolic dysfunction. Liver-derived fibroblast growth factor 21 is required for the metabolic remodelling with DTR. Strikingly, hepatocyte-selective establishment of threonine biosynthetic capacity reverses the systemic metabolic response to DTR. Taken together, our studies of ...

I admit it: I eat a high-protein diet. Not just low-carb, and not just high-fat. Its high protein.. I thought I should make a public confession because every time some dunce in the media opines that the high-protein Atkins diet will kill you, low-carbers around the world jump up and down and yell, Its not high protein! Its high fat!. Speak for yourself.. Its true that when most of us switch to a low-carb diet, we dont replace 300 grams of carbohydrate with 300 grams of protein.

Environmental perturbations during early mammalian development can affect aspects of offspring growth and cardiovascular health. We have demonstrated previously that maternal gestational dietary protein restriction in mice significantly elevated adult offspring systolic blood pressure. Therefore, the present study investigates the key mechanisms of blood pressure regulation in these mice. Following mating, female MF-1 mice were assigned to either a normal-protein diet (NPD; 18 % casein) or an isocaloric low-protein diet throughout gestation (LPD; 9 % casein), or fed the LPD exclusively during the pre-implantation period (3·5 d) before returning to the NPD for the remainder of gestation (Emb-LPD). All offspring received standard chow. At 22 weeks, isolated mesenteric arteries from LPD and Emb-LPD males displayed significantly attenuated vasodilatation to isoprenaline (P = 0·04 and P = 0·025, respectively), when compared with NPD arteries. At 28 weeks, stereological analysis of glomerular ...

Persillade is a mixture of chopped garlic and chopped parsley in French cuisine. Parsley is the main ingredient in Italian salsa verde, which is a mixed condiment of parsley, capers, anchovies, garlic, and sometimes bread, soaked in vinegar. It is an Italian custom to serve it with bollito misto or fish. Gremolata, a mixture of parsley, garlic, and lemon zest, is a traditional accompaniment to the Italian veal stew, ossobuco alla milanese. In England, parsley sauce is a roux-based sauce, commonly served over fish or gammon. Root parsley is very common in Central, Eastern, and Southern European cuisines, where it is used as a snack or a vegetable in many soups, stews, and casseroles, and as ingredient for broth. In Brazil, freshly chopped parsley (salsa) and freshly chopped scallion (cebolinha) are the main ingredients in the herb seasoning called cheiro-verde (literally "green aroma"), which is used as key seasoning for major Brazilian dishes, including meat, chicken, fish, rice, beans, stews, ...

(
  • High-Protein Diets: Are They Safe? (
  • On the other hand, there is some scarce information on the potential of dietary lectins, edible plant proteins and high protein diets to modulate angiogenesis. (
  • This argument has been raised once again due to the success of many popular high-protein weight-loss diets (which I will address in an upcoming article). (
  • There is no evidence high-protein diets cause kidney damage in healthy individuals. (
  • Concern about this is extrapolated from the evidence that high-protein diets exacerbate pre-existing kidney disorders, 7 and that when dietary protein is reduced in persons suffering with kidney disease, the progression to end-stage dysfunction has been retarded or halted. (
  • 8 As Lemon comments, if high-protein diets caused healthy kidneys to become dysfunctional, one would expect to see many athletes develop kidney problems, 5 since athletes have consumed amounts of dietary protein far greater than the RDA requirements for many years. (
  • Poortmans R, Dellaliux O. Do regular high-protein diets have potential health risk on healthy kidney functions in athletes? (

  • The 0.4% P diets (vs 1.4% P diets) significantly increased the period that GFR remained stable before it decreased, but dietary protein did not have significant effect. (
  • Despite the popularity of high protein diets, there is little research about how diets high in protein might impact men's heart failure risk. (
  • As many people seem to take the health benefits of high-protein diets for granted, it is important to make clear the possible risks and benefits of these diets,' said Jyrki Virtanen, Ph.D., study author and an adjunct professor of nutritional epidemiology at the University of Eastern Finland in Kuopio. (
  • Earlier studies had linked diets high in protein - especially from animal sources -- with increased risks of Type 2 diabetes and even death. (
  • Long-term interventions comparing diets with differential protein compositions and emphasizing differential protein sources would be important to reveal possible effects of protein intake on risk factors of heart failure. (
  • Both diets were formulated to differ only in protein source, thus providing equivalent amounts of dietary fibers and monounsaturated, polyunsaturated (including n-3), and saturated fatty acids (1.1:1.8:1.0). (

  • The authors concluded that the results indicate that gestation diets containing protein at 50 per cent and 250 per cent of recommendation and differing in protein:carbohydrate ratio led to marked changes in protein and fat metabolism in gilts resulting in foetal growth retardation of 15 per cent, which mainly occurred during the second half of gestation. (
  • Because the brain Trp levels are regulated by its ratio to large neutral amino acids (Trp:LNAA) in circulation, this study elucidated whether diets of various protein sources that contain different Trp:LNAA affect depression- and anxiety-like behaviours in C57BL/6J mice under short-day conditions (SD). (
  • Furthermore, mice on gluten or soya protein diets before transition to SD exhibited high Trp:LNAA levels in plasma under SD. (
  • Diets that are rich in high-protein foods, in combination with resistance training, have been shown repeatedly to help athletes add or retain lean mass. (
  • However, diets that include moderate or high-protein foods have plenty of other advantages. (
  • For one, as Jose Antonio, Ph.D., writes in the article " 3 Myths about High-Protein Diets Debunked ," "It's very difficult to get fat if the only thing you overfeed on is protein. (
  • High-protein diets can also help you lose unwanted weight. (
  • Protein is supplied by food ingredients, whole foods, sole-source foods and mixed diets and the match between dietary supply and human protein needs is vital to support the health and well-being of human populations. (
  • A closed respirometer was used to measure oxygen consumption of the southern catfish Silurus meridionalis fed with six isonitrogenous (48% crude protein) diets replacing 0%, 13%, 26%, 39%, 52% and 65% fish meal (FM) protein by soybean meal (SBM) protein, in order to investigate the effects of dietary soybean protein level (SPL) (replacing FM) on metabolic rates of the southern catfish. (
  • Recent trends in weight loss diets have led to a substantial increase in protein intake by individuals. (
  • Meanwhile, high-protein diets may contribute to disturbance of glucose metabolism, but evidence from prospective studies is scarce. (
  • CONCLUSIONS Diets high in animal protein are associated with an increased diabetes risk. (
  • Finisher diets with 40 per cent dried distillers grains with solubles (DDGS) decreased growth performance and economically important carcass measurements but the effects were not caused by the high level of crude protein in the diet. (
  • Many scientists (particularly in Europe) suggest that excess crude protein (CP) in diets reduces energetic efficiency in pigs. (
  • As a result, the guidelines recommend that men and boys "reduce their overall intake of protein foods" such as meat, poultry and eggs and add more vegetables to their diets. (
  • Diets that regularly exceed the recommendations for protein intake have been found to lead to an increased glomerular filtration rate in the kidneys and also have an effect on the hormone systems in the body. (
  • I'd note that BV is typically tested at very low protein intakes, far below what the average American (and certainly any athlete would eat). (
  • This claim is based on an hypothesis that artificially assembles various notions, including in vitro observations on the physical-chemical property of apatite crystal, short term human studies on the calciuric response to increased protein intakes, as well as retrospective inter-ethnic comparisons on the prevalence of hip fractures. (
  • In the elderly, low protein intakes are often observed in patients with hip fracture. (
  • In agreement with both experimental and clinical intervention studies, large prospective epidemiologic observations indicate that relatively high protein intakes, including those from animal sources are associated with increased bone mineral mass and reduced incidence of osteoporotic fractures. (
  • Intakes of meat protein, total meat, or any meat subtype were not associated with HF (heart failure) risk, either. (
  • The idea is also becoming more prevalent in the general public as people realize that higher protein intakes are better for dieting, fat loss and appetite control. (
  • This is the same level recommended by the Dietary Reference Intakes (DRIs) for a healthy diet for normal adults. (
  • Serum high sensitivity C-reactive protein (CRP) was measured, and intakes of 7 specific fatty acids (% of energy) were evaluated by a validated self-administered dietary history questionnaire. (
  • The new title for these values Dietary Reference Intakes (DRIs), is the inclusive name being given to this new approach. (
  • This new book is part of a series of books presenting dietary reference values for the intakes of nutrients. (
  • As a result, the safety of habitually consuming dietary protein in excess of recommended intakes has been questioned. (
  • While protein restriction may be appropriate for treatment of existing kidney disease, we find no significant evidence for a detrimental effect of high protein intakes on kidney function in healthy persons after centuries of a high protein Western diet. (
  • Use this tool to calculate daily nutrient recommendations for dietary planning based on the Dietary Reference Intakes (DRIs). (
  • We examined the cross-sectional association of plasma IGF-I and IGF-binding protein 3 (IGFBP-3) levels with intakes of alcohol, energy, macronutrients, micronutrients, and specific foods in 1037 healthy women. (
  • We conclude that higher energy, protein, and milk intakes were associated with higher levels of IGF-I. These associations raise the possibility that diet could affect cancer risk through influencing IGF-I level. (
  • In the present study, we examined the cross-sectional association of IGF-I and IGFBP-3 levels with intakes of various dietary factors in 1037 healthy women enrolled in the NHS. (
  • Several studies, however, have found no evidence of protein toxicity due to high protein intakes on kidney function in healthy people. (
  • Protein concentrate , a human or animal dietary supplement that has a very high protein content and is extracted or prepared from vegetable or animal matter. (
  • Study participants who took a milk protein supplement had a 2.3 millimeters of mercury (mmHg) lower systolic blood pressure, compared to when they took a refined carbohydrate supplement. (

  • The maker of a dietary supplement was sued on March 19 for allegedly spiking its products to artificially inflate the level of protein. (
  • A dietary supplement that may help deliver a boost of energy thanks to powdered caffeine and collagen. (
  • Always consult with a qualified healthcare professional prior to beginning any diet or exercise program or taking any dietary supplement. (
  • Notwithstanding the allowance in 21 CFR § 101.9(c)(7) to calculate the amount of protein to be declared in nutrition labeling of a dietary supplement or food on the basis of the factor of 6.25 times the nitrogen content of the food, the quantity of protein in a product should be calculated to include only proteins that meet the following definition: "A chain of amino acids connected by peptide bonds. (
  • Nothing in this guidance is intended to replace or conflict with any regulatory requirement established under any other subpart or section of 21 CFR Part 101 for labeling of food and dietary supplement products. (

  • The effects of dietary protein and amino acids on skeletal metabolism. (
  • The cellular and molecular mechanisms that underpin the actions of dietary protein on mineral metabolism and skeletal homeostasis remain unclear. (
  • There are likely source-specific effects of dietary protein on skeletal metabolism, the intestine and the IGF-1/IGFBP axis. (
  • Furthermore, there is no consistent evidence for superiority of vegetal over animal proteins on calcium metabolism, bone loss prevention and risk reduction of fragility fractures. (
  • Beyond their nutritional role as the source of amino acids for protein synthesis, they are instrumental in the regulation of food intake, glucose and lipid metabolism, blood pressure, bone metabolism and immune function. (
  • This review discusses the interaction of dietary proteins during digestion and absorption with the physiological and metabolic functions of the GI tract, and illustrates the importance of this interaction in the regulation of amino acid, glucose, lipid metabolism, and food intake. (
  • Protein Metabolism In Its Relation To Dietary Standards. (
  • Here, we investigate the mechanisms mediating the action of dietary phytoestrogens on lipid and glucose metabolism in rodents. (
  • The present study was aimed to observe the effects of urea ingestion, non-protein nitrogen, on the disorder of nitrogen metabolism with the L-carnitine contents using the blood, kidney, liver, and femoral muscle as markers. (
  • The present study aimed to evaluate the effect of urea ingestion as a non-protein nitrogen source, which could induce a disorder of nitrogen metabolism, on the L-carni- tine contents of various tissues. (
  • The results showed that there were no significant differences in routine metabolism among dietary treatments. (
  • Results of the present study suggested that an imbalance of essential amino acids at higher dietary SPL resulted in more energy channeled into metabolism, and subsequently increased the SDA coefficient. (
  • The idea goes like this: glucagon is the opposite of insulin, and if they're released together, as they are when you eat a high-protein meal, then their effects on blood sugar , on hunger , and on fat metabolism cancel one another out in a way that they would not following a carbohydrate-heavy meal. (
  • Titled: Dietary protein and weight reduction: a statement for healthcare professionals from the Nutrition Committee of the Council on Nutrition, Physical Activity, and Metabolism of the American Heart Association. (
  • A significant amount of research shows that many people can lose and maintain a healthy weight, support a healthy metabolism and age more vibrantly when they consume more high-quality protein," Dr. Richard Thorpe, a Texas cattle rancher and doctor, said in a statement on behalf of the National Cattlemen's Beef Association, an industry trade group. (
  • Food protein quality is traditionally dependent on its amino acid content and the availability of these amino acids in circulation, factors that would influence their metabolism within different body protein pools. (
  • Protein toxicity occurs when the body is unable to get rid of the potentially toxic wastes that are generated as a result of protein metabolism. (
  • In people with healthy kidney function, the kidneys work continuously to excrete the by-products of protein metabolism which prevents protein toxicity from occurring. (
  • Most of the problems stem from the accumulation of unfiltered toxins and wastes from protein metabolism. (
  • To test our hypothesis we assessed the inhibitory effect of protein diet restriction on prostate and breast cancer growth, serum PSA and IGF-1 concentrations, mTOR activity and epigenetic markers, by using human xenograft cancer models. (
  • Your dietitian will determine the level of protein restriction you need. (
  • Does Dietary Potassium Supplementation plus Moderate Sodium Restriction Have An Additive Blood Pressure Lowering Effect in Essential Hypertension? (
  • Recent data suggest that dietary protein restriction improves survival and delays the progression to end-stage renal disease (ESRD) in non-diabetic nephropathies. (
  • The purpose of our study was to determine the effect of dietary protein restriction on survival and progression to ESRD in diabetic nephropathy. (
  • Moderate dietary protein restriction improves prognosis in type 1 diabetic patients with progressive diabetic nephropathy in addition to the beneficial effect of antihypertensive treatment. (
  • Mus musculus was used as a model to test whether dietary protein restriction leads to changes in milk composition. (
  • Protein restriction affects fat intake and serum lipids in children with chronic renal failure. (
  • When measuring carcass characteristics, the timed protein restriction resulted in altered fat deposition, particularly subcutaneous and internal fat. (
  • Now, scientists at the Buck Institute for Age Research have shown that HIF-1 is also a key player in dietary restriction. (
  • The data in this study also points to HIF-1 as a likely target for regulating the protective effects of dietary restriction in mammals, said Kapahi. (
  • Dietary restriction is one of the most robust methods for extending lifespan and delaying age-related disease among various species. (
  • Kapahi says the molecular mechanisms involved in how dietary restriction slows cancer and extends lifespan have been largely unknown. (
  • This study gets us closer to understanding that process and gives us better targets for both designing and testing drugs which could mimic the effects of dietary restriction in humans, said Kapahi. (
  • Furthermore, it was found that the lifespan extension resulting from dietary restriction required activity in signaling pathways in the endoplasmic reticulum, the part of the cell involved in processing and the proper folding of proteins. (
  • The Modification of Diet in Renal Disease (MDRD) Study was the largest randomized clinical trial to test the hypothesis that protein restriction slows the progression of chronic renal disease. (
  • Many physicians interpreted the failure of the MDRD Study to demonstrate a beneficial effect of protein restriction over a 2- to 3-yr period as proving that this therapy does not slow disease progression. (
  • Since then, numerous secondary analyses of the MDRD Study have been undertaken to clarify the effect of protein restriction on the rate of decline in GFR, urine protein excretion, and onset of end-stage renal disease. (
  • Although these secondary results cannot be regarded as definitive, the authors conclude that the balance of evidence is more consistent with the hypothesis of a beneficial effect of protein restriction than with the contrary hypothesis of no beneficial effect. (
  • The Modification of Diet in Renal Disease (MDRD) Study was a multicenter clinical trial designed to test the hypotheses that dietary protein restriction and strict BP control would delay the progression of chronic renal disease. (
  • Although the primary analysis was inconclusive, numerous secondary analyses have been carried out using the MDRD Study database, several of which have implications for the efficacy of dietary protein restriction. (
  • The purpose of this review is to examine the results of these secondary analyses, compare them with other randomized trials, and assess the cumulative evidence regarding the efficacy of dietary protein restriction on the progression of chronic renal disease. (
  • Nonetheless, these analyses provide additional insight into the efficacy of dietary protein restriction. (

  • Some previous observational research on eating carbohydrates inconsistently suggested that a high carbohydrate diet might help reduce blood pressure," said He, an epidemiologist at Tulane University School of Public Health and Tropical Medicine in New Orleans, La. "In contrast, our clinical trial directly compares soy protein with milk protein on blood pressure, and shows they both lower blood pressure better than carbohydrates. (
  • A low carbohydrate/high protein diet can reduce body weight and visceral fat, increase the expression of ghrelin, and decline GLP-1 expression in diet-induced obesity rats. (
  • Regina had severe hypoglycaemia and eating adequate protein plus fat would also help this enormously because these slow the emptying of the stomach and allow the sugars from carbohydrate foods to enter the bloodstream more slowly. (
