The food matrix of spinach is a limiting factor in determining the bioavailability of beta-carotene and to a lesser extent of lutein in humans. (1/1433)

Carotenoid bioavailability depends, amongst other factors, on the food matrix and on the type and extent of processing. To examine the effect of variously processed spinach products and of dietary fiber on serum carotenoid concentrations, subjects received, over a 3-wk period, a control diet (n = 10) or a control diet supplemented with carotenoids or one of four spinach products (n = 12 per group): whole leaf spinach with an almost intact food matrix, minced spinach with the matrix partially disrupted, enzymatically liquefied spinach in which the matrix was further disrupted and the liquefied spinach to which dietary fiber (10 g/kg wet weight) was added. Consumption of spinach significantly increased serum concentrations of all-trans-beta-carotene, cis-beta-carotene, (and consequently total beta-carotene), lutein, alpha-carotene and retinol and decreased the serum concentration of lycopene. Serum total beta-carotene responses (changes in serum concentrations from the start to the end of the intervention period) differed significantly between the whole leaf and liquefied spinach groups and between the minced and liquefied spinach groups. The lutein response did not differ among spinach groups. Addition of dietary fiber to the liquefied spinach had no effect on serum carotenoid responses. The relative bioavailability as compared to bioavailability of the carotenoid supplement for whole leaf, minced, liquefied and liquefied spinach plus added dietary fiber for beta-carotene was 5.1, 6.4, 9.5 and 9.3%, respectively, and for lutein 45, 52, 55 and 54%, respectively. We conclude that the bioavailability of lutein from spinach was higher than that of beta-carotene and that enzymatic disruption of the matrix (cell wall structure) enhanced the bioavailability of beta-carotene from whole leaf and minced spinach, but had no effect on lutein bioavailability.  (+info)

Maternal vitamin A or beta-carotene supplementation in lactating bangladeshi women benefits mothers and infants but does not prevent subclinical deficiency. (2/1433)

The effects of maternal postpartum vitamin A or beta-carotene supplementation on maternal and infant serum retinol concentrations, modified relative dose-response (MRDR) ratios and breast milk vitamin A concentrations were assessed during a community-based trial in Matlab, Bangladesh. At 1-3 wk postpartum, women were randomly assigned to receive either (1) a single dose of 200,000 international units [60,000 retinol equivalents (RE)] vitamin A followed by daily placebos (n = 74), (2) daily doses of beta-carotene [7.8 mg (1300 RE)] (n = 73) or (3) daily placebos (n = 73) until 9 mo postpartum. Compared to placebos, vitamin A supplementation resulted in lower maternal MRDR ratios (i.e., increased liver stores) and higher milk vitamin A concentrations at 3 mo, but these improvements were not sustained. The beta-carotene supplementation acted more slowly, resulting in milk vitamin A concentrations higher than the placebo group only at 9 mo. Irrespective of treatment group, over 50% of women produced milk with low vitamin A concentrations (/=0. 06. We conclude that while both interventions were beneficial, neither was sufficient to correct the underlying subclinical vitamin A deficiency in these women nor to bring their infants into adequate vitamin A status.  (+info)

A survey of serum and dietary carotenoids in captive wild animals. (3/1433)

Accumulation of carotenoids varies greatly among animal species and is not fully characterized. Circulating carotenoid concentration data in captive wild animals are limited and may be useful for their management. Serum carotenoid concentrations and dietary intakes were surveyed and the extent of accumulation categorized for 76 species of captive wild animals at Brookfield Zoo. Blood samples were obtained opportunistically from 275 individual animals immobilized for a variety of reasons; serum was analyzed for alpha- and beta-carotene, lutein + zeaxanthin, lycopene, beta-cryptoxanthin and canthaxanthin. Total carotenoid content of diets was calculated from tables and chemical analyses of commonly consumed dietary components. Diets were categorized as low, moderate or high in carotenoid content as were total serum carotenoid concentrations. Animals were classified as unknown, high, moderate or low (non-) accumulators of dietary cartenoids. Nonaccumulators had total serum carotenoid concentrations of 0-101 nmol/L, whereas accumulators had concentrations that ranged widely, from 225 to 35,351 nmol/L. Primates were uniquely distinguished by the widest range of type and concentration of carotenoids in their sera. Most were classified as high to moderate accumulators. Felids had high accumulation of beta-carotene regardless of dietary intake, whereas a wide range of exotic birds accumulated only the xanthophylls, lutein + zeaxanthin, canthaxanthin or cryptoxanthin. The exotic ungulates, with the exception of the bovids, had negligible or nondetectable carotenoid serum concentrations despite moderate intakes. Bovids accumulated only beta-carotene despite moderately high lutein + zeaxanthin intakes. Wild captive species demonstrated a wide variety of carotenoid accumulation patterns, which could be exploited to answer remaining questions concerning carotenoid metabolism and function.  (+info)

Accumulation of astaxanthin all-E, 9Z and 13Z geometrical isomers and 3 and 3' RS optical isomers in rainbow trout (Oncorhynchus mykiss) is selective. (4/1433)

Concentrations of all-E-, 9Z- and 13Z- geometrical and (3R,3'R), (3R, 3'S) and (3S,3'S) optical isomers of astaxanthin were determined in rainbow trout liver, gut tissues, kidney, skin and blood plasma to evaluate their body distribution. Two cold-pelleted diets containing predominantly all-E-astaxanthin (36.9 mg/kg astaxanthin, 97% all-E-, 0.4% 9Z-, 1.5% 13Z-astaxanthin, and 1.1% other isomers, respectively) or a mixture of all-E- and Z-astaxanthins (35.4 mg/kg astaxanthin, 64% all-E-, 18.7% 9Z-, 12.3% 13Z-astaxanthin, and 2.0% other isomers, respectively), were fed to duplicate groups of trout for 69 d. Individual E/Z isomers were identified by VIS- and 1H-NMR-spectrometry, and quantified by high-performance liquid chromatography. Significantly higher total carotenoid concentration was observed in plasma of trout fed diets with all-E-astaxanthin (P < 0.05). The relative E/Z-isomer concentrations of plasma, skin and kidney were not significantly different among groups, whereas all-E-astaxanthin was higher in intestinal tissues and 13Z-astaxanthin was lower in liver of trout fed all-E-astaxanthin (P < 0.05). The relative amount of hepatic 13Z-astaxanthin (39-49% of total astaxanthin) was higher than in all other samples (P < 0.05). Synthetic, optically inactive astaxanthin was used in all experiments, and the determined dietary ratio between the 3R,3'R:3R, 3'S (meso):3S,3'S optical isomers was 25.3:49.6:25.1. The distribution of R/S-astaxanthin isomers in feces, blood, liver and fillet was similar to that in the diets. The ratio between (3S,3'S)- and (3R,3'R)-astaxanthin in the skin and posterior kidney was ca. 2:1 and 3:1, respectively, regardless of dietary E/Z-astaxanthin composition. The results show that geometrical and optical isomers of astaxanthin are distributed selectively in different tissues of rainbow trout.  (+info)

Carotenoid intakes, assessed by dietary questionnaire, are associated with plasma carotenoid concentrations in an elderly population. (5/1433)

High intakes of fruits and vegetables and of carotenoids are associated with a lower risk for a variety of chronic diseases. It is therefore important to test the validity of dietary questionnaires that assess these intakes. We compared intakes of five carotenoids, as calculated from responses to the Willett 126-item food-frequency questionnaire, with corresponding biochemical measures. Subjects included 346 women and 201 men, aged 67-93 y, in the Framingham Heart Study. Unadjusted correlations were higher among women than men as follows: alpha-carotene 0.33 and 0.18, beta-carotene, 0.36 and 0.25; beta-cryptoxanthin, 0.44 and 0.32; lycopene, 0.35 and 0.21; and lutein + zeaxanthin, 0.27 and 0.10, respectively. Adjustment for age, energy intake, body mass index (BMI, kg/m2), plasma cholesterol concentrations and smoking reduced the gender differences, respectively, to the following: alpha-carotene 0.30 and 0.28; beta-carotene, 0.34 and 0.31; beta-cryptoxanthin, 0.45 and 0.36; lycopene, 0.36 and 0.31; and lutein + zeaxanthin, 0.24 and 0.14. Plots of adjusted mean plasma carotenoid concentration by quintile of respective carotenoid intake show apparent greater responsiveness among women, compared with men, to dietary intake of alpha- and beta-carotene and beta-cryptoxanthin, but similar blood-diet relationships for lycopene and lutein + zeaxanthin. Reported daily intake of fruits and vegetables correlated most strongly with plasma beta-cryptoxanthin and beta-carotene among women and with plasma alpha- and beta-carotene among men. With the exception of lutein + zeaxanthin, this dietary questionnaire does provide reasonable rankings of carotenoid status among elderly subjects, with the strongest correlations for beta-cryptoxanthin. Appropriate adjustment of confounders is necessary to clarify these associations among men.  (+info)

Paracoccus carotinifaciens sp. nov., a new aerobic gram-negative astaxanthin-producing bacterium. (6/1433)

The strain E-396T, isolated from soil, was Gram-negative, aerobic, orange-pigmented, rod-shaped, motile by peritrichous flagella and astaxanthin-producing. This organism produced carotenoids, mainly astaxanthin, and did not produce bacteriochlorophyll. The ubiquinone system was Q-10. Analysis of the 16S rRNA sequence of strain E-396T showed it to be a member of the alpha-3 subclass of the Proteobacteria, forming a cluster with the species of the genus Paracoccus. On the basis of the production of orange pigments and motility by peritrichous flagella, together with DNA-DNA reassociation data, it is concluded that the new isolate should be classified into a new species of the genus Paracoccus, Paracoccus carotinifaciens sp. nov. The type strain is E-396T (= IFO 16121T).  (+info)

Double blind, cluster randomised trial of low dose supplementation with vitamin A or beta carotene on mortality related to pregnancy in Nepal. The NNIPS-2 Study Group. (8/1433)

OBJECTIVE: To assess the impact on mortality related to pregnancy of supplementing women of reproductive age each week with a recommended dietary allowance of vitamin A, either preformed or as beta carotene. DESIGN: Double blind, cluster randomised, placebo controlled field trial. SETTING: Rural southeast central plains of Nepal (Sarlahi district). SUBJECTS: 44 646 married women, of whom 20 119 became pregnant 22 189 times. INTERVENTION: 270 wards randomised to 3 groups of 90 each for women to receive weekly a single oral supplement of placebo, vitamin A (7000 micrograms retinol equivalents) or beta carotene (42 mg, or 7000 micrograms retinol equivalents) for over 31/2 years. MAIN OUTCOME MEASURES: All cause mortality in women during pregnancy up to 12 weeks post partum (pregnancy related mortality) and mortality during pregnancy to 6 weeks postpartum, excluding deaths apparently related to injury (maternal mortality). RESULTS: Mortality related to pregnancy in the placebo, vitamin A, and beta carotene groups was 704, 426, and 361 deaths per 100 000 pregnancies, yielding relative risks (95% confidence intervals) of 0. 60 (0.37 to 0.97) and 0.51 (0.30 to 0.86). This represented reductions of 40% (P<0.04) and 49% (P<0.01) among those who received vitamin A and beta carotene. Combined, vitamin A or beta carotene lowered mortality by 44% (0.56 (0.37 to 0.84), P<0.005) and reduced the maternal mortality ratio from 645 to 385 deaths per 100 000 live births, or by 40% (P<0.02). Differences in cause of death could not be reliably distinguished between supplemented and placebo groups. CONCLUSION: Supplementation of women with either vitamin A or beta carotene at recommended dietary amounts during childbearing years can lower mortality related to pregnancy in rural, undernourished populations of south Asia.  (+info)

This chapter reviews the epidemiological evidence on the effects of dietary beta-carotene on lung function, respiratory symptoms, mortality and risk of developing chronic obstructive pulmonary disease (COPD). Published studies are located by searching several electronic databases using the relevant key words. High levels of intake of beta-carotene were found to improve lung function (forced expiratory volume in one second and forced vital capacity) and appeared to have some protective effects against respiratory symptoms such as dyspnea, cough and excessive phlegm. However, no tentative conclusion on the association between dieta1y beta-carotene and both the risk and mortality of COPD can be drawn. In view of the emerging epidemiological evidence, further clinical and experimental research is required to ascertain the role of beta-carotene on the aetiology of COPD.. ...

Patients undergoing carotid endarterectomy were pretreated with low-dose, oral beta carotene to determine whether the carotenoid content of plaque could be increased in vivo. Beta carotene-treated patients had a 50-fold increase in their plaque beta carotene level from 0.066 to 3.3 micrograms beta carotene/g plaque. Microscopy and microspectrophotometry demonstrated that plaque from beta carotene-treated patients had higher carotenoid levels and higher absorption (450-500 nm) compared with control specimens, but normal media was unaffected. This demonstration of increased preferential absorption by plaque suggests that selective ablation of atherosclerotic plaque may be enhanced by pretreating patients with oral beta carotene. ...
This study determines the effect of lysophosphatidylcholine (lysoPC) and phosphatidylcholine (PC) in mixed micelles on beta-carotene and retinyl palmitate levels in rats in order to delineate the role of micellar phospholipids in the intestinal uptake of beta-carotene and its conversion into vitamin A. The rats were fed a single dose of beta-carotene solubilized in lysoPC (LPC group), PC (PC group) or no phospholipids (NoPL, control group) in micellar form. The level of beta-carotene and retinyl palmitate in plasma and beta-carotene in liver was analyzed by HPLC after 1, 2, 3, 6 and 9 h of feeding. The postprandial levels of beta-carotene in plasma (599.9 pmol/mL, Area Under Curve (AUC)) and in liver (1,161.3 pmol/g) were significantly (p,0.05) higher in the LPC group compared with its level in plasma (207.2 pmol/mL) and in liver (616.5 pmol/g) of the PC group and in plasma (119.1 pmol/mL) and in liver (626.2 pmol/g) of the NoPL group. No difference was seen between the PC and NoPL groups. The ...

Degradation of beta-carotene during storage is a problem that may prove even more troublesome for the proposed nutritional benefits of Golden Rice than its initial low levels.. Unnoticed by the media, a 2017 paper published in the Journal of Agricultural and Food Chemistry reported that the beta-carotene content of Golden Rice GR2E at harvest is short-lived (Schaub et al. 2017).. This study found Golden Rice retained only 60% of its original beta-carotene levels after 3 weeks of storage and just 13% after 10 weeks.. The apparent explanation is that the beta-carotene in Golden Rice is unstable in the presence of oxygen. Thus, under normal storage conditions, the beta-carotene in Golden Rice grains will rapidly degrade.. Under tropical farming, storage, and household conditions, degradation may be faster still.. In any event, the low levels and rapid degradation of beta-carotene measured in Golden Rice GR2E seem a significant blow to the likelihood that Golden Rice will fulfill expectations. That ...
The project is a passive follow-up of the Alpha-Tocopherol, Beta-Carotene Cancer Prevention (ATBC) Study cohort. Originally, this was a large, randomized, double-blind, placebo-controlled, 2x2 factorial primary prevention trial testing the effects of alpha-tocopherol and beta-carotene supplementation on cancer incidence and mortality. The study was conducted in Finland as a collaboration between the U.S. National Cancer Institute (NCI) and the National Public Health Institute of Finland. NCI has maintained passive surveillance of the cohort through Finnish national registries, including the cancer registry.. The primary purpose of the ATBC cohort follow-up is to use the existing risk factor data and biological specimens (i.e., serum, whole blood, DNA, red blood cells, and toenails) to test hypotheses relevant to cancer etiology, survival, early detection, and prevention. These data and biospecimens continue to provide an invaluable resource for the study of biochemical, nutritional, genetic, and ...

If you are afraid to consume meat because of some of the proposed deleterious effects and decide to supplement with vitamins A and E instead you may want to rethink that idea. An article published in the Journal of the American Medical Association (16) looked at 68 randomized trials and 230,000 participants to take a look at the effect of supplemental beta-carotene, vitamin A and E on mortality (deaths). Unfortunately, the usage of vitamin A and E supplements significantly correlated with increased mortality (16)! This means that taking long term vitamin A and E supplements may lead to death earlier then without it. Utilizing supplemental vitamin A and E products may not be advantageous, but we ...

Doctors believe antioxidants and the colorful carotenoids help protect the eye. In this analysis, doctors reviewed eight placebo-controlled trials, plus 12 studies following men and women over several years.. Overall, for every 10 mg increase per day of lutein or zeaxanthin, chances for age-related cataract declined 26 percent. Each 500 mg daily increase in vitamin C lowered chances 18 percent; each 5 mg increase in beta carotene, 8 percent; and each 5 mg daily increase in vitamin A lowered chances of cataract by 6 percent..

The term carotene (also carotin, from the Latin carota, carrot[1][2]) is used for many related unsaturated hydrocarbon substances having the formula C40Hx, which are synthesized by plants but in general cannot be made by animals (with the exception of some aphids and spider mites which acquired the synthesizing genes from fungi).[3] Carotenes are photosynthetic pigments important for photosynthesis. Carotenes contain no oxygen atoms. They absorb ultraviolet, violet, and blue light and scatter orange or red light, and (in low concentrations) yellow light. Carotenes are responsible for the orange colour of the carrot, for which this class of chemicals is named, and for the colours of many other fruits, vegetables and fungi (for example, sweet potatoes, chanterelle and orange cantaloupe melon). Carotenes are also responsible for the orange (but not all of the yellow) colours in dry foliage. They also (in lower concentrations) impart the yellow coloration to milk-fat and butter. Omnivorous animal ...
β,β-Carotene 15,15′-dioxygenase cleaves β,β-carotene into two molecules of retinal, and is the key enzyme in the metabolism of β,β-carotene to vitamin A. The enzyme has been known for more than 40 years, yet all attempts to purify the protein to homogeneity have failed. Recently, the successful cloning and sequencing of an enzyme with β,β-carotene 15,15′-dioxygenase activity from chicken, as well as from Drosophila, has been reported. Here, we describe in detail our attempt to enrich the chicken β,β-carotene 15,15′-dioxygenase to such an extent as to allow determination of partial amino acid sequences, which were then used to design degenerate oligonucleotides. Screening of a chicken duodenal expression library yielded a full-length clone containing a coding sequence of 1578bp. Functional expression in Escherichia coli and in eukaryotic cell lines confirmed that we had cloned the first vertebrate dioxygenase that cleaves β,β-carotene at the central 15,15′-double bond. By ...
p align=justify,GLV could be helpful to suggest using leafy vegetables as a part of daily meal. To achieve this goal, nutritional awareness on the importance of these GLV is warranted among various communities in the country. The present study clearly demonstrates that PC in mixed micelles suppresses the intestinal uptake, accumulation and conversion of newly absorbed β-carotene in to retinol, while lysoPC enhances β-carotene level and conversion efficiency of retinol by activating the dioxygenase. Thus, the present results suggest that the hydrolysis of PC to lysoPC is an important step for the intestinal uptake of β-carotene solubilized in mixed micelles and that dietary lysoPC modify the bioavailability of β-carotene. The mechanism of these effects of phospholipids in mixed micelles on the intestinal uptake of β-carotene and, in particular, its relationship to intestinal lipid metabolism deserves further study.,/p ...

References What Is It?. Beta-carotene is probably the best known of the carotenoids, those red, orange, and yellow pigments that give color to many fruits and vegetables. The body converts beta-carotene into Vitamin A, a nutrient first identified in the 1930s and now recognized as vital to the growth and development of the human body.. As a potent immune-system booster and a powerful Antioxidantâ€it counters the effects of molecules called free-radicals that damage cellsâ€beta-carotene plays an important role in human health.. Consuming plenty of fruits and vegetables is the best way to supply the body with beta-carotene. In addition, beta-carotene is now sold in supplement form.. Scientists have long hoped that supplements could provide concentrated sources of beta-carotene and thus provide increased protection against heart disease and even against certain cancers. But disappointing results from the well-publicized Harvard University Physicians Health Study, in which more than 22,000 ...
The present study was conducted to investigate the effect of β-carotene on the antioxidant system of rats with diabetes. Forty Sprague Dawley rats were fed the AIN-76 control diet or the same diet supplemented with β-carotene (7.2 mg/kg diet) for 3 weeks, then diabetes was induced in half the rats by administering streptozotocin (45 mg/kg BW) into the femoral muscle. Diabetic and normal rats were fed the experimental diets for 2 more weeks. To investigate the effect of dietary β-carotene on diabetes, the activities of antioxidative enzymes and glutathione concentration were determined in normal and streptozotocin-induced diabetic rats. The plasma glucose levels in diabetic rats were not influenced by the dietary supplementation of β-carotene. Hepatic activities of catalase and superoxide dismutase in diabetic rats were significantly lower than those of control rats but β-carotene tended to induce these activities. Glutathione-S-transferase activity was not significantly different between ...
An increased intake of fruits and vegetables has been shown to be associated with reduced risk of cancer. In epidemiological studies, supplements of β-carotene, which is abundant in fruits and vegetables, were not found to be beneficial in reducing the incidence of lung cancer in high-risk groups. Epoxycarotenoids are abundant in nature. 5,6-Epoxy-β-carotene was much more active than β-carotene in the induction of differentiation of NB4 cells [Duitsman, Becker, Barua and Olson (1996) FASEB J. 10, A732]. Epoxycarotenes may, therefore, have protective effects against cancer. In order to do this, however, epoxycarotenoids must be absorbed by the human body. There is no evidence that epoxycarotenoids, despite their abundance in dietary fruits and vegetables, are absorbed by humans. In this paper, it is demonstrated that orally administered dietary or synthetic epoxy-β-carotenes are absorbed by humans, as indicated by their appearance in the circulating blood.. ...
Nutritional Benefits of Parsley:. Parsley is a nutrient powerhouse containing high levels of beta carotene, vitamin B12, folate, chlorophyll, calcium, more vitamin C than citrus fruits, and just about all other known nutrients. Parsley is a moistening, nourishing, restoring, warming food, pungent with a slightly bitter, salty flavor. It enhances and stimulates the energy of organs, improving their ability to assimilate and utilize nutrients.. Beta carotene is used for protein assimilation. This nutrient benefits the liver and protects the lungs and colon. Beta-carotene is converted by the body to vitamin A, a nutrient so important to a strong immune system that its nickname is the anti-infective vitamin.. Chlorophyll Parsley is abundant in chlorophyll, thus purifying and inhibiting the spread of bacteria, fungi and other organisms. Chlorophyll from parsley is slightly anti-bacterial and anti-fungal which acts to enhance immune response and to relieve mucus congestion, sinusitis and other ...
Your body has a sophisticated method of keeping this oxidation in check, however. A group of nutrients called antioxidants swoop around the body soaking up and destroying any free radical molecules before they can cause any damage. Thankfully, antioxidants can be found in abundance if we eat a nutritious wholefood diet.. Vitamins A, C and E are a very important group of nutrients called carotenoids. These are the chemicals that give fruit and vegetables their rich colour - for example, orange and yellow colours found in squashes and carrots are from the carotenoid beta carotene. Beta carotene is converted into an active form of vitamin A, known as retinol.. Lycopene is also a strong antioxidant and gives tomatoes their wonderful red colour. Lycopene has been shown to be especially effective at repairing skin damage, as well as supporting the prostate.. Lutein and zeanthinin are also types of carotenoid and have received a lot of positive research recently. They demonstrate health-promoting ...
Although we are all susceptible to the occasional cold or flu, there are some ways to ensure that your immune system is functioning at its best.. First, enrich your diet with antioxidants. These are vitamins and minerals found in foods or supplements that help to remove harmful oxidants from the body. Oxidants are toxic byproducts of cigarette smoke, pollution, sunlight exposure, and the conversion of food to energy.. Antioxidants include Vitamin C, E, and beta carotene.. Heres a list of foods rich in those antioxidants:. Vitamin C: tomatoes, spinach, broccoli, strawberries (also high, prunes, grapes, artichoke, berries). Vitamin E: astaxanthin (salmon), wheat germ, nuts and seeds,vegetable oil, fish oil. Beta Carotene: carrots, winter squash, broccoli, sweet potatoes, cantaloupe, peaches, apricots. Second, include a wide variety of foods to ensure that you are getting adequate nutrients. Include health fat sources such as omega-3 fatty acids found in fish, nuts, seeds, and flax. Choose lean ...

The recent report1 of the study in Finland of vitamin E and beta carotene on the incidence of cancer in male smokers is important, not because of its scientific value, but for the way it was treated in the national press. The news media headlines carried the grim message vitamins may increase cancer.2 This is the message that many of my patients received, and for the next few days I received anxious calls even though my patients are much more sophisticated about vitamins than are the average individuals. They wanted reassurance that it was safe to continue with their vitamin C, or vitamin E and beta carotene. The media did not distinguish between the vitamins. There is a tendency in the public (including physicians) to have a global view of vitamins. If there is bad news about one, it means it is bad for them all. The vitamin critics were given one more opportunity to blast the use of vitamins, and to return to their ancient position that only food was safe and no one needed added ...

Are antioxidants worthless against heart disease? By Neil E. Levin, CCN, DANLA 8/15/07 In a published report, A Randomized Factorial Trial of Vitamins C and E and Beta Carotene in the Secondary Prevention of Cardiovascular Events in Women (Results From the Womens Antioxidant Cardiovascular Study), researchers concluded that, There were no overall effects of ascorbic acid (vitamin C), vitamin E, or beta carotene on cardiovascular events among women at high risk for CVD. (1) This is simply untrue. In order to reach that conclusion, the researchers had to count non-compliant subjects as taking vitamin E, even when it was obvious that they werent following the study protocol. Is that intellectually honest? I would have given the opposite conclusion. When subjects assigned to take vitamin E actually took their vitamin E, the results were significant and proved that the vitamin had benefits: Censoring participants on noncompliance led to a significant 13% reduction in the primary end ...
For instance, articles in newspapers, such as the New York Times, and incorrect statements made by well-meaning people who are expected to be nutritional experts, like Dr. Andrew Weil and Dr. Joseph Mercola, have raised unjustified concerns about vitamin A (retinol) in supplements being toxic.. Also, highly accomplished Health Ranger Mike Adams has supported sales of whole-food vitamins, which only contain beta carotene, with no true retinol vitamin A. Several large vendors of whole-foods vitamins promote this concept, too.. Vitamin A (retinol, not beta carotene) is an essential nutrient, which means that you must have it for normal health and well-being and even to stay alive. Vitamin A is critical for the health of the eyes, lungs, bones, skin, cardiovascular and immune systems and healthy pregnancy. Some other well-known sources of information began to say that people should not take vitamin A because vitamin A can be toxic.. However, this is a misunderstanding, as there are no ...
A recent journal article pointed out the widely-reported danger of smokers using beta-carotene, a natural source (provitamin) of vitamin A, as part of their multivitamins. 1 In this meta-analysis (as in common in such analyses) the researchers have neglected to consider pre-existing dietary and serum levels of this nutrient, making their claim to control by placebo inadequate to properly isolate this variable. In fact, this failure to determine the effects of beta-carotene at a dose-dependent plasma level - and by neglecting to measure total beta-carotene intake along with the relevant synergistic antioxidants associated with it, as opposed to simply measuring supplemental intake - raises serious questions about the validity of these results. 2 There is also legitimate scientific debate over the use of trans versus cis forms of this provitamin that may affect the way it is used by our bodies in vivo that dispute whether all forms are equal, which most studies simply do not address (including ...

This study examined the effects of palm carotene feeding on DNA damage of bone marrow, recovery of peripheral leukocyte counts, and the survival of mice that received whole-body X-ray irradiation. The palm carotene was composed of alpha- and beta-carotene in a ratio of 1:3. Mice were fed either a basal diet or a carotene diet (50 mg carotene/100 g diet) for 2 weeks, then irradiated. The carotene diet was prepared by the dietary protocol that markedly enhanced the accumulation of carotene in tissues (J. Nutr. 125, 3081, 1995). DNA damage in bone marrow was evaluated by micronucleus assay using peripheral blood. When mice received X-ray (1.5 Gy), marked DNA damage in bone marrow and reduction of peripheral leukocyte count were observed. These changes were significantly attenuated in mice fed the carotene diet. In addition, X-ray (6.5 Gy)-induced survival of mice fed the carotene diet was higher than those fed the basal diet. In mice fed the carotene diet, alpha- and beta-carotene were detected in ...
The aim of this work is to clarify the effect of curcumin and beta-carotene on cisplatin-induced tissue damage and to demonstrate the potential of Raman spectroscopy to detect tissue changes consistent with liver and kidney histopathology as a potential diagnostic adjunct. In the study, 56 Wistar albino female rats were used and randomly divided into 7 groups (n:8). Sham group received only sesame oil; Cisplatin group, received a single dose injection of cisplatin; Beta-carotene group, treated with beta-carotene orally; Cisplatin + Beta-carotene group, pretreated with beta-carotene 30 min prior to the cisplatin injection, then received cisplatin; Curcumin group, orally treated with curcumin; Cisplatin + Curcumin group, pretreated with curcumin 30min prior to the cisplatin injection, then received cisplatin. The second application was performed 1 week after the first application. One of the liver and kidney tissues was taken to 10% form for histopathological examinations and the others were taken ...
Carotenoids are natural pigments which are synthesized by plants and are responsible for the bright colors of various fruits and vegetables. There are several dozen carotenoids in the foods that we eat, and most of these carotenoids have antioxidant activity. β-carotene has been best studied since, in most countries it is the most common carotenoid in fruits and vegetables. However, in the U.S., lycopene from tomatoes now is consumed in approximately the same amount as β-carotene. Antioxidants (including carotenoids) have been studied for their ability to prevent chronic disease. β-carotene and others carotenoids have antioxidant properties in vitro and in animal models. Mixtures of carotenoids or associations with others antioxidants (e.g. vitamin E) can increase their activity against free radicals. The use of animals models for studying carotenoids is limited since most of the animals do not absorb or metabolize carotenoids similarly to humans. Epidemiologic studies have shown an inverse ...
The effect of beta-carotene on race performance was evaluated using eleven well-trained runners (all running 40 miles per week) while monitoring the time to complete a 5 kilometer race by K. LeBanc, Ph.D. and coworkers from Louisiana State University, Baton Rouge, LA. In addition, beta-carotenes effects on oxidative stress was also measured by malondialdehyde (MDA) concentrations, a marker of muscle damage.. These subjects were tested using a double blinded, cross-over design. During the supplemental phase, each subject ingested 25000 IU of beta-carotene daily. The results indicated that there was a statistically significant improvement in 5 kilometer race performance. The average race times during the placebo and beta-carotene phases were 19:55 minutes and 19:18 minutes respectively. In addition, 64% of the subjects noted a subjective benefit from the use of beta-carotene supplementation. There was no statistically significant effect on MDA levels.. The results of this study indicate that ...
In vitro and in vivo studies have associated iron with both the initiation and promotional stages of carcinogenesis. We investigated whether iron was associated with colorectal cancer in a nested case-control study within the α-tocopherol, β-carotene cancer prevention study cohort. Exposure was assessed at baseline, using a 276-item food frequency questionnaire and a fasting serum sample. The study included 130 colorectal cancer cases (73 colon cancers and 57 rectal cancers) and 260 controls. Conditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). Supplemental iron intake was only reported for 4 cases and 18 controls; therefore, we were unable to obtain meaningful results for this variable. Comparing the highest to the lowest quartiles, there was an inverse association between serum ferritin and colorectal cancer risk (OR = 0.4, 95% CI = 0.2-0.9) and a suggestion of an inverse association between dietary iron and colorectal cancer risk (OR = ...
Aside from GLA which comes directly from evening primrose, borage and black currant seed and indirectly from flax seed, there are many other safe and effective natural substances that can mimic the ways in which aspirin works. It must be stressed, however, that if one continues to eat a lot of sugar, refined foods, saturated fat (e.g. red meat, chicken, dairy products, etc.), does not exercise, smokes cigarettes and drinks alcohol to excess, neither aspirin nor any of the following alternatives can be guaranteed to do much good.. Beta carotene - The best source of beta carotene is whole carrots. Equally good is a live whole food concentrate of carrots. Eating carrots or swallowing live whole food carrot concentrate capsules is therefore better than just drinking carrot juice which in turn is better than just taking a beta carotene supplement. Carrot juice contains beta carotene but it also contains small amounts of protein, carbohydrate, fat, fiber, potassium, vitamin C and a long list of other ...

A start-up biotech company from South Africa, Cape Carotene, has received funding from Cape Biotech to develop technologies to produce astaxanthin, a powerful antioxidant and dietary supplement used in aquaculture, from algae. According to a report in the Cape Business News:. The algae will be grown in small, shallow ponds for a short period. The algal strain has been derived from fresh water culture collections which has been adapted for commercial use. Once grown, the algae will be stressed by changing the growth conditions which induces it to synthesize astaxanthin. Astaxanthin is produced by the cells as a secondary metabolite, which is only found in a specific cell state. The algal cells are then harvested and processed.. Although Cape Carotenes immediate target is to export the naturally produced astaxanthin to European fish and feed industries, the company also plan to develop it as a nutraceutical for human consumption. Because of its antioxidative properties, much research has been ...
A meta-analysis of 67 randomised trials with antioxidant supplements has reported that vitamins A and E, and beta-carotene may increase mortality risk by up to 16 per cent.
One of the best ways to understand why most published nutritional studies in Conventional Medicine are not helpful is precisely because the only nutrients that interests the Industry and conventional research are isolated nutrients, thanks to which they can be synthesized and patented for cash flow. However, contrarily to whole foods, isolated nutrients act like drugs with side toxic effects. Even many dietary supplements that are considered healthy by integrative doctors can have deleterious effects. Consider the findings of the effects of beta carotene and alpha-tocopherol supplements on lung cancer.. We found no reduction in the incidence of lung cancer among male smokers after five to eight years of dietary supplementation with alpha-tocopherol or beta carotene. In fact, this trial raises the possibility that these supplements may actually have harmful as well as beneficial effects. (Source). In effect, those taking the pills got more lung cancer than those who didnt, and there were more ...
Peel some carrots and kumara then throw on a pot of green beans to keep diseases and ageing at bay!. Eating lots of orange and dark green veges such as carrots, sweet potatoes and green beans may be tied to less disease and longer life, suggests a new study.. This time it is not the beta-carotene in vegetables that has the spotlight, but rather its cousin: alpha-carotene. Both are members of the carotenoid antioxidant family. Scientists believe carotenoid antioxidants promote health by counteracting oxygen-related damage to DNA.. Consumption of fruits and vegetables has long been associated with lower risks of health problems such as cancer and heart disease, said Dr. Chaoyang Li of the U.S. Centers for Disease Control and Prevention, in Atlanta, in e-mail to Reuters Health.. However, it is still not clear which elements contribute to the health effects or how they do so, he added, pointing to recent studies that have found no apparent benefit for beta-carotene supplements..

Maize has been targeted for biofortification with provitamin A carotenoids through traditional breeding. Two studies were conducted in gerbils to evaluate factors that may affect provitamin A activity. Maize diets had equal theoretical concentrations of vitamin A (VA) assuming 100% bioefficacy. Study 1 (n = 57) varied the ratio of β-cryptoxanthin and β-carotene but maintained the same theoretical VA. Study 2 (n = 67) varied lutein and zeaxanthin. Other treatments were oil, VA, or β-carotene doses. Serum and livers were analyzed for VA and carotenoids. In study 1, total liver VA did not differ among the maize groups. In study 2, total liver VA of the VA and maize groups were higher than controls (P ...

Source: New England Journal Medicine 1994; 330:1029-1035. And 18 years after this study was published it was revealed that excessive vitamin A supplementation via beta carotene (which converts to vitamin A in the body) impairs vitamin D blood levels and negates any reduction in lung cancer achieved by vitamin D supplementation. Vitamin D supplements (sunshine in a pill) were found to reduce the risk of lung cancer in sun-deprived Finnish men, but not when they consumed excessive amount of vitamin A. These Finnish men needed more vitamins, not less.. Excessive beta carotene is shuttled to the skin to provide internal sun protection and is not toxic to the liver as is mega-dose vitamin A. Most reports of liver toxicity from vitamin A supplementation emanate from alcoholics whose livers are compromised by their drinking habit.. The Council For Responsible Nutrition (CRN) says: the human data, however, are often confounded by other factors such as alcohol intake, infectious hepatitis, hepatotoxic ...
Asymmetrically cleaves beta-carotene at the 9,10 double bond resulting in the formation of beta-apo-10-carotenal and beta-ionone. Besides beta-carotene, lycopene is also oxidatively cleaved.

What does the number mean?. A UPF rating of 25 means that only 1/25th (or 4%) of the UV radiation can penetrate the fabric, giving a 96% protection against both UVA and UVB rays. A minimum UPF 15 clothing is good (94% protection), but 50+ (98%) is excellent, especially considering the effectiveness of sun protection will lessen over time, youll have longer lasting protection.. Regarding the measurement of sun protection, SPF is a bit more variable as the number is calculated based on increasing the amount of time you can spend in the sun before getting sunburned. For example, if the average person would burn after 20 minutes in the sun, a sunscreen with SPF 30 is supposed to protect against sunburn for about 10 hours. This effectiveness varies widely because some peoples skin burns more easily, the mid day hours have more intense UVB rays, and even most water repellant sunscreens wear off with sweat and water. Also, the SPF calculation does not account for the UVA rays.. Diet. Most people ...

Ah yes, then came Golden rice. In my third year of university, I sat in my plant physiology class hearing about golden rice for the first time. I was in complete awe, and in that moment I decided I wanted to be involved in biotechnology in one way or another. Golden rice was modified to produce beta-carotene, a precursor of vitamin A. The idea was to prevent vit A deficiency, which is caused by malnutrition, and kills almost 700 000 children under the age of 5 annually. Naysayers argued and argued against golden rice, first saying there wasnt enough vitamin A being produced, so scientists went in and made new strains producing even more beta-carotene. Then came the arguments that the use of golden rice would create a slippery slope for more widespread GMO use. Because thats the real concern, forget the millions of people who are affected by vitamin deficiencies. Golden rice is still being argued over, but has generally been shown to have sufficient levels of beta-carotene, and that the levels ...

Lycopene is one of the major carotenoids in Western diets and is found almost exclusively in tomatoes and tomato products. It accounts for about 50% of carotenoids in human serum. Among the common dietary carotenoids lycopene has the highest singlet oxygen quenching capacity in vitro. Other outstanding features are its high concentration in testes, adrenal gland and prostate. In contrast to other carotenoids its serum values are not regularly reduced by smoking or alcohol consumption but by increasing age. Remarkable inverse relationships between lycopene intake or serum values and risk have been observed in particular for cancers of the prostate, pancreas and to a certain extent of the stomach. In some of the studies lycopene was the only carotenoid associated with risk reduction. Its role in cancer risk reduction still needs to be clarified. Patients with HIV infection, inflammatory diseases and hyperlipidemia with and without lipid lowering treatment may have depleted lycopene serum ...
Forgetfulness, lack of orientation, cognitive decline about 700,000 Germans suffer from Alzheimers disease (AD). Now researchers from the University of Ulm, among them the Epidemiologist Professor Gabriele Nagel and the Neurologist Professor Christine von Arnim, have discovered that the serum-concentration of the antioxidants vitamin C and beta-carotene are significantly lower in patients with mild dementia than in control persons. It might thus be possible to influence the pathogenesis of AD by a persons diet or dietary antioxidants. 74 AD-patients and 158 healthy controls were examined for the study that has been published in the Journal of Alzheimers Disease (JAD). ...
Long-term supplementation with beta-carotene did not affect the incidence of cancer or cardiovascular disease in men. The CARET trial is 1 of a series of important randomized trials that tests the efficacy of dietary supplements. The study design is exemplary, although follow-up is relatively short (median 3.7 y). Patients in the target group (men exposed to asbestos and long-term smokers, 44% of whom were women) were at high risk for lung cancer and cardiovascular disease. The finding that patients who were randomized to β-carotene and vitamin A had an increase in overall mortality and lung cancer deaths, plus an increase in cardiovascular mortality, is contrary to the observational studies that show a lower mortality rate with higher intake of fruits and vegetables (1). Intriguingly, the baseline serum β-carotene levels in this study were inversely correlated with subsequent development of lung cancer. Because supplements had no beneficial effect on survival, this finding needs to be ...

Consuming large meals causes the stomach to produce large amounts of stomach acid, which tends to cause ulcers. It is better to eat smaller meals. Diets for ulcers should be low in fat and sugar and high in fiber. A diet that is rich in oily fish, such as salmon, mackerel, sardines and herring, helps to line the stomach and alimentary canal and prevent the break in the stomach lining. Eat fresh fruits and vegetables, such as carrots, kale, kiwi and apricots, which help to protect the stomach lining with beta carotene, but avoid citrus. Foods rich in vitamin E, such as wheatgerm and hazelnuts are also known for intestinal healing properties. ...

In 1996, the United States Food and Drug Administration (FDA) published regulations requiring the addition of folic acid to enriched breads, cereals, flours, corn meals, pastas, rice, and other grain products.[95][96] This ruling took effect on January 1, 1998, and was specifically targeted to reduce the risk of neural tube birth defects in newborns.[97] There were concerns expressed that the amount of folate added was insufficient.[98] As a result of the folic acid fortification program, fortified grain foods became a major source of folic acid in the American diet.[8][99] The Centers for Disease Control and Prevention in Atlanta, Georgia used data from 23 birth defect registries covering about half of United States births, and extrapolated their findings to the rest of the country. These data indicate that since the addition of folic acid in grain-based foods as mandated by the FDA, the rate of neural tube defects dropped by 25% in the United States.[100] Before folic acid fortification, about ...
