Coffee prevents eye sight damage from glaucoma, aging and diabetes

Another study published in the Journal of Agricultural and Food Chemistry has highlighted the benefits of consuming coffee and its potential anti-oxidant activity. Previous studies have revealed that coffee impacts on lowering the risk chronic diseases as Parkinson’s, prostate cancer, diabetes, Alzheimer’s and age-related cognitive declines. This study demonstrated its impact on eye sight. The retina is found on the inside back wall of the eye and contains millions of light-sensitive cells and other nerve cells that receive and process visual information. It is also one of the most metabolically active tissues, demanding high levels of oxygen and making it prone to oxidative stress. The lack of oxygen and production of free radicals leads to tissue damage and loss of sight.

Coffee contains chlorogenic acid (CLA), a strong anti-oxidant that prevents retinal degeneration in mice. Mice eyes were treated with nitric oxide, which creates oxidative stress and free radicals, leading to retinal degeneration, but mice pretreated with CLA developed no retinal damage.

The study is “important in understanding functional foods, that is, natural foods that provide beneficial health effects,” said Chang Y. Lee, professor of food science and the study’s senior author.

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.
