Raw coffee is, on average, just 1% caffeine, and it contains 7% to 9% chlorogenic acid, a strong antioxidant that prevents retinal degeneration in mice, according to the study, published in the Journal of Agricultural and Food Chemistry.
The retina is a thin tissue layer on the back wall of the eye with millions of light-sensitive cells and other nerve cells that receive and organize visual information. It is 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 lead to tissue damage and loss of sight. Retinal degeneration can be caused by glaucoma, aging and diabetes.
