It seems as if each passing week scientists discover another health benefit of everyone’s favorite caffeinated drink, coffee. Their most recent research concludes that aside from an energy jolt, coffee may prevent deteriorating eyesight and retinal degeneration due to glaucoma, aging and diabetes.

The key to this discovery lies in the chlorogenic acid (CLA), a strong antioxidant found in your cup of Joe.  A Cornell study published in the Journal of Agricultural and Food Chemistry back in December found that when they pretreated mice with CLA, they developed no retinal damage after they were given doses of nitric oxide.

The retinal itself is a thin tissue layer on the inside, back wall of the eye that receives and organizes visual information. Retinal degeneration is a result of oxidative stress and free radicals due to a lack of oxygen. With the information discovered by scientists, they can take research to the next step to determine whether drinking coffee facilitates CLA to cross a membrane known as the blood—retinal barrier. Once this is proven, doctors may one day recommend an appropriate brew to prevent retinal damage.
