Low levels of vitamin e in the blood may contribute to cataracts. Canada, a study showed that elderly people taking vitamin e 50% less than against cataracts.

Diet appropriate to eat cabbages, broccoli, sunflower oil, peanut oil, cereals, beans, dark green vegetables, liver, eggs, and dairy products, you can get more vitamin e. Recently published studies show that dietary intake p carotene and other carotenoids in the greatest number of people, who consume the least reduce by half the risk of developing cataracts.
