'Age-related cataracts are the leading cause of low vision and blindness throughout the world. Up to 30% of people over the age of 50 will develop them. By age 75, about 70% will have cataracts. Surgery to remove cataracts has become almost routine.
Cataracts develop when proteins build up in the lens of the eye making it cloudy. It happens with age and is primarily due to oxidative damage. Age-related cataracts are the result of a lifetime of molecular damage to the lens proteins by free radicals.
Can your diet make a difference? Studies to date haven't been conclusive. Animal studies have found that wheat grass reverses cataract damage. Human studies have found only a non-significant or modest association between fruit and vegetable intake and cataract risk.'
