In the new study, Prof. Y·Li, a professor of food science at Cornell University, and colleagues have exposed the eyes of some experimental rats to nitric oxide gas, which causes oxidative stress and free radicals. Exposure to the gas is more likely to cause retina. Degenerative lesions. The comparative study found that the experimental mice treated with this technique did not undergo retinal degeneration even in nitric oxide compared with the experimental mice that were not pretreated with the antioxidant chlorogenic acid (CLA).
Professor Li pointed out that raw coffee contains about 9% chlorogenic acid, and this highly effective phenolic natural antioxidant can effectively prevent retinal degeneration. The retina is the most metabolically active tissue in the body. It is a thin layer of light and nerve cells on the posterior wall of the eye. Insufficient oxygen and free radical production in the body can cause damage to the retina.
Professor Li said that the amount of CLA in animal experiments is comparable to that of humans drinking one cup of coffee a day, which indicates that drinking coffee can effectively reduce the risk of retinal damage. At the same time, drinking coffee also helps prevent vision loss and blindness from a variety of causes.
The US Journal of Agriculture and Food Chemistry published a new study by the Korea Institute of Science and Technology and found that drinking 3 or more cups of coffee a day can reduce the risk of type 2 diabetes by more than 37%. Previously, the study also found that drinking 4 cups of coffee a day reduced the risk of liver cancer by 42%. Another study found that drinking 2 or more cups of coffee a day reduced the risk of cirrhosis by 66%. Drinking coffee also helps prevent Parkinson’s disease and liver disease.
