Carotenoid actions and their relation to health and disease.
Lutein bioavailability is higher from lutein-enriched eggs than from supplements and spinach in men.
The lUTEin bioavailability from egg is higher than that from other sources such as lutein, lute in ester supplements, and spinach, and this finding may have implications for dietary recommendations that may decrease the risk of certain diseases, e.g., ARMD.

Lutein supplementation increased MPOD eccentrically and DHA resulted in central increases, which may be due to changes in lipoproteins.

Reviewed studies were heterogeneous and lacked the methodologic rigor to draw any conclusions regarding the effects of dietary cholesterol on CVD risk, and carefully adjusted and well-conducted cohort studies would be useful to identify the relative effects.
Healthy lifestyles related to subsequent prevalence of age-related macular degeneration.
Modifying lifestyles might reduce risk for early AMD as much as 3-fold, lowering the risk for advanced AMD in a person's lifetime and the social and economic costs of AMD to society.
Xanthophyll (lutein, zeaxanthin) content in fruits, vegetables and corn and egg products
Predictors of optical density of lutein and zeaxanthin in retinas of older women in the Carotenoids in Age-Related Eye Disease Study, an ancillary study of the Women's Health Initiative.
Macular pigment optical density (MPOD) is directly related to dietary intake of lutein and zeaxanthin but even more strongly to serum concentrations, which may reflect unmeasured physical and medical factors that influence the uptake, distribution, and utilization of lutenin and zexanthin.
