A cup of coffee a day may keep retinal damage away

I can't stand the taste of coffee. Too bitter.

Chlorogenic acid is also present in black tea.

Coffee drinkers, rejoice! Aside from java’s energy jolt, food scientists say you may reap another health benefit from a daily cup of joe: prevention of deteriorating eyesight and possible blindness from retinal degeneration due to glaucoma, aging and diabetes.

Raw coffee is, on average, just 1 percent caffeine, but it contains 7 to 9 percent chlorogenic acid, a strong antioxidant that prevents retinal degeneration in mice, according to a Cornell study published in the Journal of Agricultural and Food Chemistry.

Previous studies have shown that coffee also cuts the risk of such chronic diseases as Parkinson’s, prostate cancer, diabetes, Alzheimer’s and age-related cognitive declines.

Chlorogenic acid and its isomers also occur in the fruit, leaves, and other tissues of dicotyledenous plants.

The chlorogenic acids in coffee beans are destroyed when the beans are roasted. But J. A. Vinson and colleagues at the University of Scranton (PA) recently found that consuming the chlorogenic acid–rich extracts of green coffee beans promotes weight loss and improves glucose tolerance in humans.
