To Prevent Cataracts, Eat Produce

Another reason to eat fruits and vegetables high in vitamin C: They may help re­­duce the risk of the most common type of age-related cataracts.

In a study of 1,000 pairs of female twins (average age 62) in the U.K., researchers found that women consuming the most dietary vitamin C at baseline had a 20 percent reduced risk of such cataracts, called nuclear cataracts, compared to those who consumed the least. Ten years later, a follow-up of 324 of the pairs of twins found that those who consumed the most C were 33 percent less likely to have their cataracts progress. The researchers also estimated that about one-third of the difference in disease progression was related to genetic factors, the rest to lifestyle factors such as diet.

Taking vitamin C (or other nutrients) in supplement form was not associated with reduced risk.

Previous clinical trials on supplements and cataract risk have had inconsistent results. The study appeared in the journal Ophthalmology.
