A report published in the Journal of Nutrition reveals the results of a study that found a lower risk of metabolic syndrome among those with higher serum levels of vitamin C and carotenoids.
May A. Beydoun of the National Institutes on Aging (NIA) and her associates evaluated data from up to 11,845 men and women enrolled in National Health and Nutrition Examination Survey (NHANES) 2001-2006. Anthropometric measurements and blood pressure were assessed upon enrollment and blood samples were analyzed for the antioxidant nutrients retinol, retinyl esters, carotenoids, vitamin C and vitamin E, as well as glucose, lipids, C-reactive protein and other factors.
Participants with metabolic syndrome had significantly lower vitamin D and higher total homocysteine levels. Having higher serum carotenoid or vitamin C was associated with a lower adjusted risk of metabolic syndrome in men and women, while retinol and retinyl esters were associated with a protective effect only in men.
