Ever think that you can see things and read things better after that first cup of coffee in the morning? There may be a reason for that, and it’s not just because you’re finally awake after your first sips of coffee. According to a new study from Cornell University, coffee helps prevent deteriorating eyesight.
The study claims that raw coffee contains roughly 1% caffeine and about 7-9% chlorogenic acid, an antioxidant that prevents the retinas from degenerating in mice.
The retina is a thin layer of tissue that rests on the back wall of your eye. It’s responsible for detecting color and it holds the optic nerve cells that receive and interpret what you see. The retina is one of the most metabolically active tissues in your body, so it is prone to oxidative stress. Damage to the retina causes sight loss, and retinal degeneration can be caused by old age, diabetes, and glaucoma. The study suggests that consuming chlorogenic acid found in coffee daily can provide the antioxidant stress relief your retinas need.
The study is “important in understanding functional foods, that is, natural foods that provide beneficial health effects,” said Chang Lee, professor of food science and the study’s senior author. “Coffee is the most popular drink in the world, and we are understanding what benefit we can get from that.”
Other studies have shown that coffee helps reduce the risk of diabetes, which in turn can also help your eyes.
So yes, drink up your coffee in the morning! Your eyes will thank you for it!
