Daily a cup of coffee good for health


A daily cup of coffee can help stop your eyes from aging and eyesight loss, according to a new study.

According to food scientists, a daily cup of coffee can prevent eyesight deterioration and possible blindness from retinal degeneration due to glaucoma, aging and diabetes, writes Tech Times.

The benefits are due to antioxidants, specifically chlorogenic acid (CLA), which is present in coffee, say a team of Korean and U.S. researchers who conducted the joint study effort. The research, conducted on mice, shows that CLA appears to stop retinal degeneration. The study is “important in understanding functional foods, that is, natural foods that provide beneficial health effects,” Chang Y. Lee, Professor of food science and senior author of the study, said in a statement.

“Raw coffee is, on average, just one percent caffeine but it contains seven to nine percent chlorogenic acid – a strong antioxidant that prevents retinal degeneration in mice,” Lee said in a statement.

The retina is a thin tissue layer on back wall of the eye with millions of light-sensitive cells and other nerve cells that receive and organise visual information.

The tissue layer is one of the most metabolically active tissues in the body – requiring high levels of oxygen and making it susceptible to oxidative stress. The lack of oxygen and production of free radicals can lead to tissue damage and loss of sight.
“Coffee is the most popular drink in the world, and we are understanding what benefit we can get from that,” Lee said in a statement.

Research on coffee drinking habits have shown that coffee cuts the risk of chronic diseases such as Parkinson’s, prostate cancer, diabetes, Alzheimer’s and age-related cognitive declines.

While promising, the research results needs further scrutiny, say researchers – it is not yet clear if consumption of coffee provides CLA directly to the retina.

The study was published in the Journal of Agricultural and Food Chemistry.
