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. (1/470)

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)

A survey of serum and dietary carotenoids in captive wild animals. (2/470)

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)

Carotenoid intakes, assessed by dietary questionnaire, are associated with plasma carotenoid concentrations in an elderly population. (3/470)

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)

Comparison of serum carotenoid responses between women consuming vegetable juice and women consuming raw or cooked vegetables. (4/470)

The objective of this study was to examine serum concentrations of alpha-carotene, beta-carotene, lutein, lycopene, and beta-cryptoxanthin due to consumption of vegetable juice versus raw or cooked vegetables. Subjects included female breast cancer patients who had undergone surgical resection and who were enrolled in a feasibility study for a trial examining the influence of diet on breast cancer recurrence. A high-vegetable, low-fat diet was the focus of the intervention, and some of the subjects were specifically encouraged to consume vegetable juice. At 12 months, blood samples were collected and analyzed for carotenoid concentrations via high-performance liquid chromatography methodology. Matched analysis and paired t test were conducted on two groups: those who consumed vegetable juice (the juice group) and those who consumed raw or cooked vegetables (no juice group). Serum concentrations of alpha-carotene and lutein were significantly higher in the vegetable juice group than in the raw or cooked vegetable group (P < 0.05 and P = 0.05, respectively). Paired t test analysis did not demonstrate a significant difference in serum values of beta-carotene, lycopene, and beta-cryptoxanthin between subjects consuming juice and those not consuming any juice. These results suggest that alpha-carotene and lutein appear to be more bioavailable in the juice form than in raw or cooked vegetables. Therefore, the food form consumed may contribute to the variability in serum carotenoid response to vegetable and fruit interventions in clinical studies.  (+info)

Determination of the stoichiometry and strength of binding of xanthophylls to the photosystem II light harvesting complexes. (5/470)

Xanthophylls have a crucial role in the structure and function of the light harvesting complexes of photosystem II (LHCII) in plants. The binding of xanthophylls to LHCII has been investigated, particularly with respect to the xanthophyll cycle carotenoids violaxanthin and zeaxanthin. It was found that most of the violaxanthin pool was loosely bound to the major complex and could be removed by mild detergent treatment. Gentle solubilization of photosystem II particles and thylakoids allowed the isolation of complexes, including a newly described oligomeric preparation, enriched in trimers, that retained all of the in vivo violaxanthin pool. It was estimated that each LHCII monomer can bind at least one violaxanthin. The extent to which different pigments can be removed from LHCII indicated that the relative strength of binding was chlorophyll b > neoxanthin > chlorophyll a > lutein > zeaxanthin > violaxanthin. The xanthophyll binding sites are of two types: internal sites binding lutein and peripheral sites binding neoxanthin and violaxanthin. In CP29, a minor LHCII, both a lutein site and the neoxanthin site can be occupied by violaxanthin. Upon activation of the violaxanthin de-epoxidase, the highest de-epoxidation state was found for the main LHCII component and the lowest for CP29, suggesting that only violaxanthin loosely bound to LHCII is available for de-epoxidation.  (+info)

Algae displaying the diadinoxanthin cycle also possess the violaxanthin cycle. (6/470)

According to general agreement, all photosynthetic organisms using xanthophyll cycling for photoprotection contain either the violaxanthin (Vx) cycle or the diadinoxanthin (Ddx) cycle instead. Here, we report the temporal accumulation of substantial amounts of pigments of the Vx cycle under prolonged high-light stress in several microalgae thought to possess only the Ddx cycle. In the diatom Phaeodactylum tricornutum, used as a model organism, these pigments also participate in xanthophyll cycling, and their accumulation depends on de novo synthesis of carotenoids and on deepoxidase activity. Furthermore, our data strongly suggest a biosynthetic sequence from Vx via Ddx to fucoxanthin in P. tricornutum. This gives experimental support to the long-stated hypothesis that Vx is a common precursor of all carotenoids with an allenic or acetylenic group, including the main light-harvesting carotenoids in most chlorophyll a/c-containing algae. Thus, another important function for xanthophyll cycling may be to optimize the biosynthesis of light-harvesting xanthophylls under fluctuating light conditions.  (+info)

Lutein and zeaxanthin concentrations in plasma after dietary supplementation with egg yolk. (7/470)

BACKGROUND: The food matrix in which carotenoids are found affects their bioavailability. Lutein and zeaxanthin are abundant in egg yolks and accumulate in the macular region of the retina, where they may affect visual function. OBJECTIVE: We sought to determine whether plasma lutein and zeaxanthin concentrations are elevated after dietary supplementation with egg yolk. DESIGN: Eleven moderately hypercholesterolemic men and women consumed 2 separate baseline diets, which contained 29-33% of energy as total fat, with 20% of energy as either beef tallow or corn oil. These diets were supplemented with cooked chicken egg yolks (1.3 egg yolks/d for an intake of 10.4 MJ). Each subject consumed all 4 diets. Each diet was consumed for 4.5 wk, with a washout period of >/=2 wk between diet phases. At the end of each diet phase, fasting morning plasma samples were collected and stored for carotenoid analysis by HPLC. Commercial chicken egg yolks were analyzed for carotenoids and cholesterol. RESULTS: Egg yolk supplementation of the beef tallow diet increased plasma lutein by 28% (P < 0.05) and zeaxanthin by 142% (P < 0.001); supplementation of the corn oil diet increased plasma lutein by 50% (P < 0.05) and zeaxanthin by 114% (P < 0.001). Changes in plasma lycopene and beta-carotene were variable, with no consistent trend. Egg yolk supplementation increased plasma LDL-cholesterol concentrations by 8-11% (P < 0.05). CONCLUSIONS: Egg yolk is a highly bioavailable source of lutein and zeaxanthin. The benefit of introducing these carotenoids into the diet with egg yolk is counterbalanced by potential LDL-cholesterol elevation from the added dietary cholesterol.  (+info)

Bioavailability of lutein from vegetables is 5 times higher than that of beta-carotene. (8/470)

BACKGROUND: To gain more insight into the relation between vegetable consumption and the risk of chronic diseases, it is important to determine the bioavailability of carotenoids from vegetables and the effect of vegetable consumption on selected biomarkers of chronic diseases. OBJECTIVE: To assess the bioavailability of beta-carotene and lutein from vegetables and the effect of increased vegetable consumption on the ex vivo oxidizability of LDL. DESIGN: Over 4 wk, 22 healthy adult subjects consumed a high-vegetable diet (490 g/d), 22 consumed a low-vegetable diet (130 g/d), and 10 consumed a low-vegetable diet supplemented with pure beta-carotene (6 mg/d) and lutein (9 mg/d). RESULTS: Plasma concentrations of vitamin C and carotenoids (ie, alpha-carotene, beta-carotene, lutein, zeaxanthin, and beta-cryptoxanthin) were significantly higher after the high-vegetable diet than after the low-vegetable diet. In addition to an increase in plasma beta-carotene and lutein, the pure carotenoid-supplemented diet induced a significant decrease in plasma lycopene concentration of -0.11 micromol/L (95% CI: -0.21, -0.0061). The responses of plasma beta-carotene and lutein to the high-vegetable diet were 14% and 67%, respectively, of those to the pure carotenoid- supplemented diet. Conversion of beta-carotene to retinol may have attenuated its plasma response compared with that of lutein. There was no significant effect on the resistance of LDL to oxidation ex vivo. CONCLUSIONS: Increased vegetable consumption enhances plasma vitamin C and carotenoid concentrations, but not resistance of LDL to oxidation. The relative bioavailability of lutein from vegetables is higher than that of beta-carotene.  (+info)

We aimed to examine the effect of different doses of lutein supplementation on visual function in subjects with long-term computer display light exposure. Thirty-seven healthy subjects with long-term computer display light exposure ranging in age from 22 to 30 years were randomly assigned to one of three groups: Group L6 (6 mg lutein/d, n 12); Group L12 (12 mg lutein/d, n 13); and Group Placebo (maltodextrin placebo, n 12). Levels of serum lutein and visual performance indices such as visual acuity, contrast sensitivity and glare sensitivity were measured at weeks 0 and 12. After 12-week lutein supplementation, serum lutein concentrations of Groups L6 and L12 increased from 0.356 (SD 0.117) to 0.607 (SD 0.176) mu mol/l, and from 0.328 (SD 0.120) to 0.733 (SD 0.354) mu mol/l, respectively. No statistical changes from baseline were observed in uncorrected visual acuity and best-spectacle corrected visual acuity, whereas there was a trend toward increase in visual acuity in Group L12. Contrast ...
A daily dose of 10 mg lutein supplementation induced an increase in mean plasma lutein by a factor of 5 and a linear 4-week increase in relative MP density of 4% to 5%. To our knowledge, this is the first study in which the effects of intake of lutein have been assessed with objective measurement techniques. In particular, the SLO-based technique provided very reliable results. With this technique all subjects showed a significant increase in MP density. The spectral reflectance analysis provided noisier results that did not allow such a conclusion for all individuals. Figure 4 shows a comparison between our results on naive subjects and heterochromatic flicker photometry data from literature. Landrum et al. 6 published results of a study of 20 weeks of supplementation of 30 mg lutein per day derived from marigolds in two skilled subjects who were measured four to five times week. The noise in their results seems comparable to that in our technique. They found a 4-week increase of 4.2% in ...

A low MP density could be a risk factor for age-related macular degeneration. Little information is available regarding MP density in relation to serum lutein and zeaxanthin and adipose lutein concentrations in a general population. Objective: The objective was to investigate the associations between MP density and serum lutein, serum zeaxanthin, and adipose lutein, taking into account potential confounders in a population. Design: Volunteers (n = 376) aged 18¿75 y were recruited. In a ...
Purpose: Lutein has been shown to be beneficial in maintaining visual function in age-related macular degeneration (AMD). A dairy beverage has been developed based on lutein-enriched egg yolks and buttermilk. The eggs have been enriched in lutein via the feed of laying hens. The primary aim of this study was to assess the effects of 1-year daily consumption of this dairy drink containing lutein-enriched egg-yolks on macular pigment optical density (MPOD) and visual scores in subjects with early AMD. Also, plasma lutein concentrations, and serum lipids and lipoproteins were measured.. Methods: One hundred and one subjects were recruited to participate in this one-year, double blind, placebo-controlled intervention trial in subjects with early signs of AMD. Subjects in the lutein group consumed the dairy drink containing 1.4 mg lutein daily. MPOD using heterochromatic flicker photometry, best corrected visual acuity (BCVA), and dark adaptation were measured at the start of the study, after 6 ...
This study investigated the antioxidant and cytotoxic effect of oxidized lutein using human cervical carcinoma cell lines (HeLa). Liposome contained phosphatidylcholine (20 micromol) in Tris-HCl buffer and lutein (200 micromol) was exposed to sunlight for 100 min. Photo-oxidized lutein products were characterized by LC-MS (APCI(+)) and studied for their antioxidant property and apoptosis in terms of cell viability, glutathione and malondialdehyde (MDA) levels. Photo-oxidized lutein fragmented ions were identified as 523 (M+ + H+-3CH3), 476 (M+ + H+-6CH3), 551 (M+ + H+-H2O) and its isomers as 13-Z lutein, 13-Z lutein, 13-Z zeaxanthin, all-E zeaxanthin, 9-Z lutein, 9-Z lutein. Free radical scavenging activity of oxidized lutein was higher by 45.9% (IC(50), 3.71 microg) than lutein (IC(50), 5.28 microg). Oxidized lutein lowered the lipid peroxidation by 20.7% than lutein. The viability of HeLa cells, glutathione and MDA levels were decreased by 64%, 40% and 18% than lutein. To conclude, oxidized lutein
In one of our earliest EduFacts briefings (Macular Pigment Density, Dietary Carotenoids and Age-Related Macular Degeneration) we reviewed a study which documented a near-twenty percent increase in macular pigment (MP) density in subjects fed a diet vigorously enriched with spinach and corn (1). The high levels of dietary spinach and corn effectively boosted lutein intake approximately 4-fold and zeaxanthin intake 3-fold. In the same article we reviewed 2 other studies relating increased serum (2) and dietary intake (3) of these dietary carotenoids with reduced risk of age related macular degeneration (AMD). While the value of adequate dietary levels of lutein and zeaxanthin is generally recognized, the value of using lutein/zeaxanthin supplements is disputed. However, a recent (1997) experimental study demonstrates that the use of a lutein supplement can directly generate an increase in the density of the protective macular pigment (4). Landrum, Bone, and colleagues serially measured macular ...

Antioxidant and light filtering protection for healthy visual function Lutein is a carotenoid found in a vast number of fruits and vegetables. Like other carotenoids, lutein has antioxidant activity in various tissues, but is only one of two that is stored within the retina where it promotes the integrity and density of the macular pigment, a key component of ocular health. Multiple clinical studies suggest a direct relationship between lutein supplementation and macula lutein concentration. Lutein uptake reportedly occurs in the receptor layer of the eye through a soluble carotenoid-binding protein called tubulin. Clinical trials have indicated that lutein specifically supports vision health through a combination of pigment associated antioxidant protection and light screening mechanisms. Furthermore, a two-year, double-blind, placebo-controlled pilot study reported that lutein may support healthy visual function in older individuals more efficiently than alpha tocopherol.

Vitamin C aids Lutein, Calcium Fights Polyps, Higher Vitamin D Needs Vitamin C Helps Lutein Absorption Higher intakes of lutein have been linked to a lower risk of developing age-related macular degeneration. Since the levels of lutein associated with eye health are much higher than the amounts we typically get from our diet, many people now take lutein supplements to close that dietary gap. Results from a recent study suggest that it may be better to take supplements of lutein along with vitamin C (1). To learn whether other antioxidants affect the absorption of lutein from supplements, researchers from the University of Wisconsin gave young healthy men and women supplements of lutein alone, or combined with vitamins C or E. Whether given alone or with one of the vitamins, absorption of lutein varied greatly among individuals. However lutein was absorbed significantly faster when given simultaneously with vitamin C. Calcium Works Against Polyps In 1999, Dartmouth Medical School researchers ...
Purpose: To determine whether supplementation with lutein and zeaxanthin improves macular pigment and visual function in patients with early age-related macular degeneration (AMD).. Design: Randomized, double-masked, placebo-controlled trial. Participants:. Participants with probable AMD who were 50 to 79 years of age were screened for study eligibility from the local communities. One hundred eight subjects with early AMD were recruited.

Lutein belongs to the carotenoid family of antioxidants. Lutein has been found in the eye, brain, breast and cervix. Research has shown lutein to be supportive for vision health. In the eye, it is found mainly in the macular region, as well as the entire retina, ciliary iris bodies and lens. As an antioxidant, lutein helps protect macular tissue from photo-oxidation by filtering blue light, and prevents oxidative damage by free radical quenching. Adequate levels of lutein in the eye may potentially be supportive in the absorption and dissipation of damaging UV radiation. Research shows that lutein supplementation can increase serum levels of lutein, and increase macular pigment density.

Lutein (L) and zeaxanthin (Z) status can be quantified by measuring their concentrations both in serum and, non-invasively, in retinal tissue. This has resulted in a unique ability to assess their role in a number of tissues ranging from cardiovascular to central nervous system tissue. Recent reports using animal models have suggested yet another role, a developmental increase in bone mass. To test this, we assessed L and Z status in 63 young healthy adults. LZ status was determined by measuring LZ in serum (using HPLC) and retina tissue (measuring macular pigment optical density, MPOD, using customized heterochromatic flicker photometry). Bone density was measured using dual-energy X-ray absorptiometry (DXA). Although serum LZ was generally not related to bone mass, MPOD was significantly related to bone density in the proximal femur and lumbar spine. In general, our results are consistent with carotenoids, specifically LZ, playing a role in optimal bone health.
3R,3R,6R)-Lutein (1) and (3R,3R)-zeaxanthin (5) are dietary carotenoids that are found in most fruits and vegetables. Numerous studies have shown that 1 and 5 play an important role in the prevention of age-related macular degeneration (AMD) that is the leading cause of blindness. To date, the metabolic pathways of 1 and 5 in ocular tissues of an animal model in relation to AMD have not been explored. This is primarily because of the lack of a viable method for the synthesis of 1 and 5 that can be labeled with a stable isotope. Among the eight possible stereoisomers of lutein, only 1 has been previously prepared by total synthesis in 14 steps in an overall yield of 0.5%. The total synthesis of lutein, zeaxanthin, and their stereoisomers from (rac)-alpha-ionone has been accomplished by a C15+C10+C15 coupling strategy. Therefore, (3R,3R,6R)-lutein (1, 8%), (3R,3S,6S)-lutein (2, 7%), (3R,3S,6R)-lutein (3, 6%), and (3R,3R,6S)-lutein (4, 7%) were each prepared in a high optical purity in 7 ...
Age-related macular degeneration (AMD) is a disease with multiple risk factors, many of which appear to involve oxidative stress. Macular pigment, with its antioxidant and light-screening properties, is thought to be protective against AMD. A result has been the appearance of dietary supplements containing the macular carotenoids, lutein and zeaxanthin. More recently, a supplement has been marketed containing, in addition, the third major carotenoid of the macular pigment, meso-zeaxanthin. The purpose of the study was to determine the effectiveness of such a supplement in raising macular pigment density in human subjects. A 120 day supplementation study was conducted in which 10 subjects were given gel-caps that provided 20 mg/day of predominantly meso-zeaxanthin, with smaller amounts of lutein and zeaxanthin. A second group of 9 subjects were given gel caps containing a placebo for the same 120 day period. Prior to and during the supplementation period, blood serum samples were analyzed by high
Retinal pigment epithelial (RPE) cells are central to retinal health and homoeostasis. Oxidative stress-induced damage to the RPE occurs as part of the pathogenesis of age-related macular degeneration and neovascular retinopathies (e.g., retinopathy of prematurity, diabetic retinopathy). The xanthophyll carotenoids, lutein and zeaxanthin, are selectively taken up by the RPE, preferentially accumulated in the human macula, and transferred to photoreceptors. These macular xanthophylls protect the macula (and the broader retina) via their antioxidant and photo-protective activities. This study was designed to investigate effects of various carotenoids (β-carotene, lycopene, and lutein) on RPE cells subjected to either hypoxia or oxidative stress, in order to determine if there is effect specificity for macular pigment carotenoids. Using human RPE-derived ARPE-19 cells as an in vitro model, we exposed RPE cells to various concentrations of the specific carotenoids, followed by either graded hypoxia or
1. Showed a 30% reduced macular pigment density in eyes with AMD.. 2. Found a correlation between reduced macular pigment density and increased lens density (cataracts) in seniors; and. 3. Demonstrated that macular pigment density can be increased with dietary and/or supplemental Lutein. Maintaining sufficient levels of Lutein & Zeaxanthin (the only Carotenoid antioxidants active in the retina) can prevent ARMD and Cataracts and preserve youthful visual sensitivity.. Most individuals supplementing with sublingual Lutein and Zeaxanthin report reduced glare and visual fatigue; improved contrast sensitivity. Vinpocetine (vin-po-seh-teen) an extract from periwinkle seeds (vinca major) has been well researched and available in Europe for the past twenty years. Recently, it became available as a dietary supplement. Vinpocetine has been included in this formula for safer and more effective circulatory benefits to the entire retina. There are no known negative interactions with other dietary ...
Lutein is a carotenoid, the family of nutrients responsible for giving vegetables their bright yellow or orange color. All carotenoids are excellent anti-oxidants, helping to protect cells against damage caused by free radicals, but lutein also plays an important role in healthy vision. The retina at the back of the eye is responsible for processing the images our eyes see. A part of the retina called the macula is especially sensitive to the blue and ultraviolet portions of the light spectrum. Lutein is concentrated in the macula, and helps support the pigment density that protects the macula from damage, by filtering out blue and ultraviolet light. We are born with lutein in our eyes, but the body cannot make this nutrient on its own, so replenishment can only come from diet. Dark, leafy green, or bright cruciferous vegetables are good sources of lutein, but many people have diets lacking in sufficient quantities of these types of food. As well, regardless of diet, the amount of lutein in the ...
The aim of the present study was to evaluate the effects of lutein and lycopene supplementation on carotid artery intima-media thickness (CAIMT) in subjects with subclinical atherosclerosis. A total of 144 subjects aged 45-68 years were recruited from local communities. All the subjects were randomly assigned to receive 20 mg lutein/d (n 48), 20 mg lutein/d+20 mg lycopene/d (n 48) or placebo (n 48) for 12 months. CAIMT was measured using Doppler ultrasonography at baseline and after 12 months, and serum lutein and lycopene concentrations were determined using HPLC. Serum lutein concentrations increased significantly from 0·34 to 1·96 μmol/l in the lutein group (P, 0·001) and from 0·35 to 1·66 μmol/l in the combination group (P, 0·001). Similarly, serum lycopene concentrations increased significantly from 0·18 to 0·71 μmol/l in the combination group at month 12 (P, 0·001), whereas no significant change was observed in the placebo group. The mean values of CAIMT decreased significantly ...
Low prices on Lutein! Nutritional support for eye health*. Poor nutrition is one of the leading causes of eye deterioration. Studies show that lutein is an important component of visual function and healthy vision depends on good nutrition.* Lutein is a naturally occurring antioxidant carotenoid found in large concentrations in the eye. Lutein in the macula protects the eyes by blocking harmful blue light rays.
Lutein and zeaxanthin belong to the xanthophyll family of carotenoids and are the two major components of the macular pigment of the retina. The macula lutea or yellow spot in the retina is responsible for central vision and visual acuity. Lutein and zeaxanthin are the only carotenoids found in both the macula and lens of the human eye, and have dual functions in both tissues - to act as powerful antioxidants and to filter high-energy blue light.1 Lutein is found in high amounts in human serum.2 In the diet it is found in highest concentrations in dark green, leafy vegetables (spinach, kale, collard greens, and others), corn, and egg yolks.3 Zeaxanthin is the major carotenoid found in corn, orange peppers, oranges, and tangerines (Table 1).4 In addition to playing pivotal roles in ocular health, lutein and zeaxanthin are important nutrients for the prevention of cardiovascular disease, stroke, and lung cancer. They may also be protective in skin conditions attributed to excessive ultraviolet ...

There is epidemiological evidence of a relationship between low plasma concentrations of lutein and zeaxanthin on the one hand, and the risk of developing age-related macular degeneration (AMD) on the other. Some studies support the view that supplemental lutein and/or zeaxanthin help protect against AMD. There is also epidemiological evidence that increasing lutein and zeaxanthin intake lowers the risk of cataract development. On September 10, 2007, in a 6-year study, researchers, led by John Paul SanGiovanni of the National Eye Institute, Maryland found that Lutein and zeaxanthin (nutrients in eggs, spinach and other green vegetables) protect against blindness (macular degeneration), affecting 1.2 million Americans, mostly after age 65. Lutein and zeaxanthin reduce the risk of AMD (journal Archives of Ophthalmology). Foods considered good sources of the nutrients also include kale, turnip greens, collard greens, romaine lettuce, broccoli, zucchini, corn, garden peas and Brussels sprouts.[1] ...
It is believed that different populations have different distributions of macular pigments [11]. Studies to determine MPOD in certain populations have been performed in many locations, including China [14], Australia [16], Central Europe [12], and South Asia [17]. Mean MPOD values have varied substantially from one study to the other. Mean MPOD obtained from a sample from Central Europe (0.126 d.u. ± 0.004) is very close to this Brazilian sample (0.14 d.u. ± 0.05). The remaining studies found higher values: mean MPOD in Australia was 0.41 d.u. ± 0.20; mean MPOD in South Asia was 0.43 d.u. ± 0.14; and mean MPOD in China was 0.303 d.u. ± 0.097. A possibility for this difference could be the technique used to determine MPOD. This study and the one performed in Central Europe were the only ones to use the Visucam 500 (Carl Zeiss Meditec, Jena, Germany). The studies performed in South Asia and Australia used the subjective HFP method. However, the literature shows a strong correlation between ...

Lutein is an important eye-protective nutrient. This study investigates the protective effects and mechanisms of lutein on lipopolysaccharides (LPS)-induced uveitis in mice. Lutein, suspended in drinking water at a final concentration of 12.5 and 25 mg/mL, was administered to mice at 0.1 mL/10 g body weight for five consecutive days. Control and model group received drinking water only. Uveitis was induced by injecting LPS (100 mg per mouse) into the footpad in the model and lutein groups on day 5 after the last drug administration. Eyes of the mice were collected 24 hours after the LPS injection for the detection of indicators using commercial kits and reverse transcription-polymerase chain reaction. LPS-induced uveitis was confirmed by significant pathological damage and increased the nitric oxide level in eye tissue of BALB/C mice 24 hours after the footpad injection. The elevated nitric oxide level was significantly reduced by oral administration of lutein (125 and 500 mg/kg/d for five days) before
Lutein and zeaxanthin are xanthophylls in the family of carotenoids found in common foods including spinach, peas, and broccoli. These compounds are unique being highly concentrated in the macular region of the retina and function as antioxidants and as filters for high-energy blue light [1]. Studies in primates and in adults suggest that lutein and zeaxanthin may help provide protection against oxidative and blue light damage [2, 3]. Lutein is a structural component of the eye and is a potent antioxidant. Lutein is well suited for protecting the retina from oxidative damage compared with other chain-breaking antioxidants in the eye like alpha-tocopherol (Vitamin E). Lutein can return singlet oxygen to ground state by temporarily becoming triplet-state lutein and then dissipating the energy as heat. This process can be repeated over and over again, because the lutein molecule remains intact after the energy transfer [4]. No data currently exists which demonstrates that lutein supplementation ...
Costs associated with age-related macular degeneration could be avoided through more widespread lutein & zeaxanthin supplementation, says Frost & SullivanLO...
Lutein and zeaxanthin are members of the carotenoid family, a family best known for another one of its members, carotene (see Beta-Carotene). They are natural fat-soluble yellowish pigments found in some plants, algae and photo-synthetic bacteria. They serve as accessory light-gathering pigments and to protect these organism against the toxic effects of ultra-violet radiation and oxygen. They also appear to protect humans against phototoxic damage. Lutein and zeaxanthin are found in the macula of the human retina, as well as the human crystalline lens. They are thought to play a role in protection against age-related macular degeneration and age-related cataract formation. They also be protective against some forms of cancer. This two carotenoids are sometimes referred to as macular yellow, retinal carotenoids or macular pigment.. ...
Supplements of a lycopene-rich tomato nutrient complex or lutein may protect against the damaging effects of UV exposure on the skin, says a new study.
Lutein is a carotenoid antioxidant and essential nutrient for eye health and good vision. As a powerful antioxidant carotenoid, it reduces risks of developing cataract and helps prevent a condition called age-related macular degeneration (AMD), or loss of central vision. Macular degeneration occurs naturally as a result of old age. Nutritional deficiencies, genetics, disease and free radical damage affect eye health directly, causing damage that produces physical changes significant enough to impair normal vision. Our body does not synthesize or produce lutein itself, so we need to meet our daily requirements from dietary sources or dietary supplements.. The nutrient-pigment being physically present in the retina and macula lutea area of our eyes, good eyesight would not be possible without it. What is interesting is that getting enough lutein has been shown to lead to improve pigment density in the macula lutea area of the retina (Dietary modification of human macular pigment density). In ...
Lutein Eyes Advanced provides a high level of Lutein per capsule. Lutein has powerful antioxidant properties and is intended to provide nutritive support for eye health. Many people think of Lutein as the eye vitamin, as it is easily transported around the body, especially to the parts of the eyes called the macula and the lens. It is one of two major carotenoids found as a color pigment in the human eye (macula and retina) and is thought to function as a light filter, protecting the eye tissues from sunlight damage. Additional herbs and whole foods are included in this unique formula for added eye health support. Directions: ...
from:Robert O. Young New findings from UCLA indicate that Lutein -- a carotenoid recently discovered in California avocados and found in green vegetables -- can help protect against prostate cancer. This study was presented at the American Institute of Cancer Research (AICR) meeting in July 2001 in Washington D.C. In recent studies, Lycopene -- a carotenoid found in tomatoes -- was associated with a reduced risk of prostate cancer, but lutein had not been linked to prostate cancer prevention until now. According to Dr. David Heber, director of the UCLA Center for Human Nutrition and author of What Color Is Your Diet, the study initially focused on a rural area of China, which had a low incidence of prostate cancer despite a diet virtually free of lycopene (due to lack of tomato intake) but rich in lutein (due to a high consumption of green vegetables). The study was then expanded to include Chinese American men and Caucasian men. UCLA lab tests showed that lutein reduced prostate cancer cell ...
Lutein is a naturally occurring carotenoid found in many fresh fruits and vegetables.

Early age-related macular degeneration (AMD) is an early hallmark of irreversible vision impairment accompanying with senescence of macular. Given the fact in treatment, prevention strategy is thought to be an efficient and robust approach to diminish early AMD patients in low-income countries, however, feasible cocktail provision in most developing nations remain mysteries. Here we proposed an effective cocktail treatment with different amounts of lutein and zeaxanthin could increase the macular pigment optical density (MPOD) and serum xanthophylls concentrations among randomized Chinese AMD patients; and might improve visual function measured by visual performance indices such as best-spectacle corrected visual acuity (BSCVA), contrast sensitivity (CSF), flash recovery time (FRT), multifocal electroretinogram (mfERG) and microperimetry ...

Carotenoids have many biological effects,23 and can function as antioxidants to protect eye tissues against free radicals.4-6 The only source of carotenoids for humans is food, and the carotenoid availability in plasma is critical in long term maintenance of adequate tissue levels. A correlation exists between carotenoid intake and plasma carotenoid concentrations.24 However, the individual variability in plasma response to carotenoid intake in humans is large.25The mechanisms providing the transport of carotenoids from intestine to the tissues are not clearly understood. Scita et al 26 proposed that the uptake of carotenoids in cultured small intestine cells of rats takes place in the absence of any receptor regulation. The postprandial incorporation into lipoproteins could be demonstrated in normolipaemic subjects for β carotene by Cornwell et al in 1962.27 The transport of the carotenoids in blood, and the distribution to the different tissues is done by lipoproteins.

A composition of matter comprising a capsule or tablet, sized and designed for oral ingestion by a human, containing the 3R-3′R stercoisorner of zeaxanthin. The 3R-3′R stereoisomer of zeaxanthin constitutes at least about 90 percent of all zeaxanthin, while S-S and S-R stereoisomers constitute less than about 10 percent of all zeaxanthin in the capsule or tablet. The capsule or tablet contains a sufficient quantity of the 3R-3′R stereoisomer of zeaxanthin to cause a detectable increase in zeaxanthin concentration in retinal tissue, or at least about 0.5 milligrams. It can be concentrated into an oily fluid or prepared in a microencapsulated granular formulation. The zeaxanthin can also be added to various types of foods, such as margarine, dairy products, syrup, cookie dough, and meat preparations. When consumed, the zeaxanthin can help treat and prevent eye diseases including macular degeneration, a leading cause of vision loss.
Uptake, metabolism, and stabilization of xanthophyll carotenoids in the retina are thought to be mediated by specific xanthophyll-binding proteins (XBPs). A membrane-associated XBP was purified from human macula using ion-exchange chromatography followed by gel-exclusion chromatography. Two-dimensional gel electrophoresis showed a prominent spot of 23 kDa and an isoelectric point of 5.7. Using mass spectral sequencing methods and the public NCBI database, it was identified as a Pi isoform of human glutathione S-transferase (GSTP1). Dietary (3R,3R)-zeaxanthin displayed the highest affinity with an apparent Kd of 0.33 microm, followed by (3R,3S-meso)-zeaxanthin with an apparent Kd of 0.52 microm. (3R,3R,6R)-Lutein did not display any high-affinity binding to GSTP1. Other human recombinant glutathione S-transferase (GST) proteins, GSTA1 and GSTM1, exhibited only low affinity binding of xanthophylls. (3R,3S-meso)-Zeaxanthin, an optically inactive nondietary xanthophyll carotenoid present in the human
The xanthophyll cycle involves the enzymatic removal of epoxy groups from xanthophylls (e.g. violaxanthin, antheraxanthin, diadinoxanthin) to create so-called de-epoxidised xanthophylls (e.g. diatoxanthin, zeaxanthin). These enzymatic cycles were found to play a key role in stimulating energy dissipation within light-harvesting antenna proteins by non-photochemical quenching- a mechanism to reduce the amount of energy that reaches the photosynthetic reaction centers. Non-photochemical quenching is one of the main ways of protecting against photoinhibition.[3] In higher plants, there are three carotenoid pigments that are active in the xanthophyll cycle: violaxanthin, antheraxanthin, and zeaxanthin. During light stress, violaxanthin is converted to zeaxanthin via the intermediate antheraxanthin, which plays a direct photoprotective role acting as a lipid-protective anti-oxidant and by stimulating non-photochemical quenching within light-harvesting proteins. This conversion of violaxanthin to ...

An excess of dietary carotenoids may cause a marked orange discoloration of the outermost skin layer. This benign and reversible condition - which is most easily observed in light-skinned people and may be mistaken for jaundice - is known as carotenosis or carotenoderma or carotenodermia. Carotenemia or carotenaemia (xanthaemia) is the presence of the orange pigment carotene in the blood from excessive intake of carrots or other vegetables containing the pigment resulting in increased serum carotenoids. Carotenoids are lipid-soluble compounds that include alpha- and beta-carotene, beta-cryptoxanthin, lycopene, lutein, and zeaxanthin. The primary serum carotenoids are beta-carotene, lycopene, and lutein. Serum levels of carotenoids vary between region, ethnicity, and sex in the healthy population. All are absorbed by passive diffusion from the gastrointestinal tract and are then partially metabolized in the intestinal mucosa and liver to vitamin A. From there they are transported in the plasma ...
Research performed at Schepens Eye Research Institute and the Department of Ophthalmology, Harvard Medical School, has established that dietary zeaxanthin plays an essential role in protecting the retina of the eye from the damaging effects of light and may help prevent age-related macular degeneration (AMD). From the many carotenoids in the diet, the human retina selectively accumulates only two: zeaxanthin and lutein, and they are known as the macular pigment because their concentration in the macula is so high. Because these carotenoids absorb blue light and because they are powerful antioxidants, scientists have hypothesized that they protect the retina.. To test this hypothesized protection, the team selected Japanese quail because the retina resembles the human macula in having more cone photoreceptors than rods and in highly selective accumulation of zeaxanthin and lutein from their diet.

Epidemiologic evidence suggests that serum carotenoids are potent antioxidants and may play a protective role in the development of chronic diseases including cancers, cardiovascular disease, and inflammatory diseases. The role of these antioxidants in the pathogenesis of diabetes mellitus remains unclear.This study examined data from a cross-sectional survey to investigate the association between serum carotenoids and type 2 diabetes.Study participants were adults aged > or = 25 y (n = 1597) from 6 randomly selected cities and towns in Queensland, Australia. Study examinations conducted between October and December 2000 included fasting plasma glucose, an oral-glucose-tolerance test, and measurement of the serum concentrations of 5 carotenoid compounds.Mean 2-h postload plasma glucose and fasting insulin concentrations decreased significantly with increasing quintiles of the 5 serum carotenoids--alpha-carotene, beta-carotene, beta-cryptoxanthin, lutein/zeaxanthin, and lycopene.

It is true that spinach can save your eyes. It can prevent and even undermine the process of macular degeneration that can eventually lead to incurable blindness. Spinach has this function because that it has lutein and zeaxanthin which are two strong antioxidants for eyes. Lutein and zeaxanthin work coordinately as a pair of invisible glasses to protect you from eye problems associated with age. Spinach is one of the rich sources of these two antioxidants. Taking 6 mg of lutein and zeaxanthin per day is enough for average people. For those who want to treat macular degeneration, the amount should be 11-12 mg every day. There is research showing that eating spinach will improve the vision of people who are suffering from macular degeneration. Besides spinach, other leafy greens like Romaine lettuce, broccoli and zucchini are also rich in lutein and zeaxanthin.

Writing in this month?s issue of the Journal of Nutritional Biochemistry, UCLA scientists note that avocados are the richest source of lutein among commonly eaten fruits. This carotenoid acts as an antioxidant and has been linked to a reduced risk of prostate cancer in previous studies.. In a new study, they looked at the inhibition of human prostate cancer cell growth when exposed to an extract of whole avocado fruit versus treatment with pure lutein. Dr David Heber, director of the UCLA center for human nutrition, and colleagues showed that when avocado extract was added to two lines of prostate cancer cells, cell growth was inhibited by up to 60 percent, whereas purified lutein alone was ineffective. Whats really exciting about this study is that the results indicate that the carotenoids, vitamins, and diverse compounds in avocados might have additive or synergistic effects against prostate cancer compared with pure lutein alone, said Heber.. Our results suggest that further studies ...

In the new study, the researchers investigated which method of preparation is the best way of obtaining lutein. They chose to study spinach, which contains comparatively high levels of lutein and is eaten by many people. Just as many other nutrients, lutein is degraded by heat.. What is unique about this study is that we have used preparation methods that are often used when cooking food at home, and we have compared several temperatures and heating times. We have also investigated methods of preparation in which the spinach is eaten cold, such as in salads and smoothies, says Lena Jonasson, professor in the Department of Medical and Health Sciences and consultant in cardiology.. In order to simulate methods of preparation that are often used in everyday life, the researchers purchased baby spinach at a supermarket. They subjected the spinach to, for example, frying, steaming, or boiling for up to 90 minutes, and measured the lutein content at different times ...
