Green Leafy Vegetables and Eye Health

Friday, March 26, 2010

Carrots arent the only vegetable good for the eyes. Leafy green vegetables and colored fruits are also beneficial to eye health. Dr. Edward Hill discusses a University of Georgia study on eye health in todays 60 Second Housecall.

Dr. Hill:

Green leafy vegetables and colored fruits and vegetables may affect visual performance and may prevent age-related eye diseases.

These foods contain the carotenoids which play an important role in vision and have a positive impact on the retina. Carotenoids are found in kale and spinach, among other vegetables.

Carotenoids may help reduce disability and discomfort from glare, enhance contrast and reduce photostress recovery times and also may increase visual range.

University of Georgia researchers reviewed multiple studies of the effects of carotenoids on visual performance.

While there are about 600 carotenoids identified in nature, only a fraction is absorbed by people. Of the 20 carotenoids found in human blood, only lutein and zeaxanthin are found in the visual system.

Green leafy vegetables are arguably one of the richest sources of nutrition and have numerous health advantages. They contain high levels of dietary fiber, magnesium, potassium, folic acid, calcium and even Omega-3 fatty acids, which aid in digestive regulation, increase bone strength and boost the immune system.
