Past research has established that specific vitamins and nutrients or healthy eating in general can help prevent the development of cataracts.
But a new British study has investigated the link between vegetarian, vegan and low-meat diets and developing the condition. The study focused on more than 57 000 people and concluded that the risk of cataracts was highest in meat eaters, but steadily decreased with low meat eaters (15% less risk), fish eaters (those who ate fish but not meat, 21% less risk), vegetarians (30% less risk) and vegans (40% less risk). Cataracts causes misting and clouding of the normally transparent eye lens. If not treated, this condition can lead to a loss of vision. The only effective treatment is surgical replacement with an artificial lens.
