Can cutting back on red meat help keep your vision sharper longer? Yes, according to a study by England’s Oxford University, particularly with regard to risk of age-related cataracts.
The decade-long study, which tracked more than 27,000 people, showed a definite correlation between the consumption of red meat and risk for the development of age-related cataracts. Participants over age 65 who ate a vegetarian diet had the lowest risk of cataracts, while their counterparts who ate the most read meat had the highest risk.
Cataracts, a gradual clouding of the lens of the eye that can significantly impair vision, are among the most common age-related problems. About 60% of people between 65 and 74 develop cataracts, and as many as 90 percent of people over 75 develop cataracts. In the initial stages special glasses can help somewhat, but the only effective treatment for cataracts is surgery.
