Three vitamins—along with certain nutrients known as carotenoids—have been associated with a lower risk of age-related cataract (ARC) in a recent study.
More than 24.4 million Americans 40 and older have cataracts, in which the eye’s lens becomes cloudy. By age 75, about half of the population has them. Chinese researchers analyzed the results of eight randomized trials and 12 cohort studies to see how nutrient intake affected cataract risk.
According to results published in the American Journal of Clinical Nutrition, ARC risk reduction was linked to consumption of vitamins A, C and E as well as the carotenoids beta carotene, lutein and zeaxanthin; the last two have long been linked to reduced risk of another age-related eye disorder called macular degeneration.
