In marginally nourished children, information is scarce regarding the circulating concentrations of carotenoids and tocopherols, and physiological factors influencing their circulating levels. We determined the serum concentrations of carotenoids, tocopherols and retinol at steady state and in response to a 9-week vegetable diet intervention in 9-12-year-old girls (n=54) and boys (n=65) in rura...
The “vitamin E” family consists primarily of four naturally occurring tocopherols (alpha-, beta-, gammaand delta-) and four unsaturated corresponding tocotrienols, which differ in their structure by the composition of methyl groups attached to the chromanol ring. Apart from their potent antioxidant activity, it is hypothesized that some of these compounds might play protective role against canc...
PURPOSE To determine whether higher levels of individual carotenoids and tocopherols in the serum are related to less severe nuclear and cortical opacities within the general population. METHODS Levels of individual carotenoids and tocopherols in the serum were determined in 400 randomly selected persons aged 50 to 84 years participating in the Nutritional Factors in Eye Disease Study of Beav...
