Red Wine May Prevent Blindness: This Week on AOL Health

We've all heard many reasons why red wine has some health-improving benefits, from its high antioxidant content to protecting the brain after a stroke. And now a new study reveals another potential positive for red wine drinkers: preventing blindness.

The ingredient in red wine known as resveratrol is responsible for sight preservation, and it can also be found in blueberries, peanuts and grapes. The results are most promising for those who suffer from blinding conditions like diabetic retinopathy and age-related macular degeneration. The researchers also found that resveratrol can block angiogenesis, or the rapid formation of new blood vessels -- a key factor in some cancers and a syndrome which affects the arterial blood vessels.
