Blood antioxidants changes in young women following beta-carotene depletion and repletion.
This study was undertaken to investigate the relationship between beta-carotene intake and biochemical indices of antioxidant status in the blood of nine premenopausal women ages 18 to 42. Nine healthy adult women were fed a low beta-carotene diet for 68 days. During the last week of the study, they received an additional mixed carotenoid supplement. Erythrocyte catalase activities seemed to parallel GP activities. Our results are consistent with the suggestion that carotenes may be important in the prevention of oxidative damage.
