can coffee really protect eyes?

the researchers exposed the eyes of some experimental mice to nitric oxide gas, which can cause oxidative stress and free radical production, and exposure to this gas is more likely to lead to retinal degeneration. The results of comparative study showed that compared with the rats not pretreated with the antioxidant chlorogenic acid (CLA), the rats pretreated with the technology did not develop retinal degeneration even in the presence of nitric oxide.

experts pointed out that raw coffee contains about 9% chlorogenic acid, which is a highly effective phenolic natural antioxidant and can effectively prevent retinal degeneration. Retina is the most active metabolic tissue in the body. It is a thin tissue composed of many light sensitive and nerve cells in the posterior wall of eyeball. Lack of oxygen and the production of free radicals in the body can lead to retinal damage.

experts said that in animal experiments, the dosage of CLA is equivalent to that of one cup of coffee per day in humans, which shows that regular coffee drinking can effectively reduce the risk of retinal injury. At the same time, drinking coffee also helps to prevent the risk of visual deterioration and blindness caused by various reasons.

new studies also found that drinking 3 or more cups of coffee a day reduced the risk of type 2 diabetes by more than 37%. Previously, the study also found that drinking four cups of coffee a day reduced the risk of liver cancer by 42%.

another study found that drinking two or more cups of coffee a day reduced the risk of liver cirrhosis by 66%. Drinking coffee also helps prevent Parkinson’s disease and liver disease.
