A Cup A Day Keeps Your Vision Healthy
Hip-hip-hooray its National Coffee Day! And the good news for those of you that enjoy a hot cup everyday - research has shown that drinking coffee can help prevent a host of vision degenerating diseases like glaucoma and diabetes. Coffee contains a powerful antioxidant called chlorogenic acid (CLA). This antioxidant prevented retinal degeneration in a study done by Cornell and published in the Journal of Agricultural and Food Chemistry.
Why is this important? Your retina is a thin layer of tissue located on the back wall of the eye. It contains millions of light sensitive cells - these cells organize visual information - they help your brain take in an image and process it. These cells can degenerate, with age and because of diseases like glaucoma and diabetes.
"Since scientists know that CLA and its metabolites are absorbed in the human digestive system, the next step for this research is to determine whether drinking coffee facilitates CLA to cross a membrane known as the blood-retinal barrier. If drinking coffee proves to deliver CLA directly into the retina, doctors may one day recommend an appropriate brew to prevent retinal damage. Also, if future studies further prove CLA's efficacy, then synthetic compounds could also be developed and delivered with eye drops," quoted from Science Daily.
In recent years, coffee has been shown to have many other health-boosting benefits. So, in celebration of National Coffee Day - brew a cup and enjoy, knowing your drinking to your eye health!
