Coffee may help protect eyesight
Researchers from Cornell University say they may have found another health benefit of coffee – protection against deteriorating eyesight, and perhaps even blindness.
The source of that protection, the scientists said, is a compound called chlorogenic acid (CGA), an antioxidant that has been associated with a number of health benefits, including weight loss and lowering of blood pressure. About 7 to 9 percent of each coffee bean is CGA.
For their study, the team first tested the effects of CGA on retinal ganglion cells (RGCs) -- the neurons located near the inner surface of the retina. These cells were were exposed to hypoxia--oxygen deprivation. The scientists found that cell damage was reduced if the cells were treated with CGA. Overall, the findings suggest that coffee consumption may prevent retinal degeneration.
