Can Drinking Coffee Be Good For Your Eyes?
Drinking Coffee May Protect Your Vision
You may have heard before that drinking coffee is bad for you, mainly because of the caffeine that it contains. You may have even told your own kids they couldn’t drink coffee because it would stunt their growth and stain their teeth. Sound familiar? Most parents probably say this, including your own parents. But recent studies show that drinking coffee can actually have benefits for your health, including protecting your eye health.
A compound found in raw coffee beans called chlorogenic acid, or CGA, which is an antioxidant that has many health benefits associated with it, such as reducing blood pressure and helping people to lose weight. CGA is what gives coffee its acidic taste and nutty, bitter aroma. One coffee bean contains between seven and nine percent of CGA, which may not sound like a lot, but that small amount actually has a big effect on your body health, including your eyes.
CGA and Your Eyes
Researchers from Cornell University have released a recent study that shows that CGA may be able to prevent retinal degeneration. The retina is located at the back of the eye and contains light-sensitive cells and nerve cells. These cells are what allow your eyes to receive and organize the information that you see, but they are susceptible to a condition called hypoxia.
Hypoxia causes parts of your body to become deprived of oxygen and can result in severe damage to those areas. When retinas are deprived of oxygen they become damaged, which can lead to various eye diseases and conditions such as diabetic retinopathy, macular degeneration, and glaucoma. All of these conditions can result in varying degrees of blindness.
Since CGA is beneficial for other areas of your health, scientists were interested to see what kind of effect it would have on preventing hypoxia and degeneration in the eyes. The study, which was published in the Journal of Agricultural and Food Chemistry, was performed on mice and the outcome shows that it is possible that CGA and coffee extract could prevent retinal degeneration.
CGA is also being looked at as a reliable preventive measure to health conditions such as diabetes, mainly diabetic cataracts. However, more time and research must still be done in order to fully learn its effectiveness when it comes to the human cases.
So enjoy the smell and taste of your morning brew, knowing that it has the potential to do more than just wake you up!
