NEW EVIDENCE SUPPORTS GRAPES' BENEFITS TO EYE HEALTH

Eating grapes may help protect eye health, according to new research published in the journal Nutrition. The study showed that a diet supplemented with grapes was able to counter damage from oxidative stress and preserve retinal structure and function in a laboratory model of retinal degeneration. Natural components in grapes that help promote antioxidant activity are thought to be responsible for these beneficial effects, in keeping with previous studies that indicate grape-derived compounds are biologically active in the retina.

The retina is the part of the eye that contains the cells that respond to light, known as photoreceptors. There are two types of photoreceptors: rods and cones. Retinal degenerative diseases cause progressive photoreceptor death and irreversible vision impairment, including blindness, affecting millions of people in the U.S. Elevated oxidative stress is strongly associated with retinal disease and has been widely studied in the development of age-related macular degeneration and other retinal degenerations.

In this new grape study, researchers at the Bascom Palmer Eye Institute at the University of Miami Miller School of Medicine, investigated whether a diet supplemented with grapes, in the form of whole grape freeze-dried powder, would protect the photoreceptors of the retina from degeneration induced by acute oxidative stress. ...
