Does green tea promotes good eye health

While the antioxidants in green tea, specifically catechins, have been studied extensively in humans and have been proven to offer many disease-fighting health benefits, researchers have been unsure whether the catechins in green tea pass from the stomach and gastrointestinal tract into eye tissues. A new study conducted by researchers at Hong Kong Eye Hospital suggests that green tea is absorbed in large amounts by certain eye structures and does provide protection from oxidative stress harmful to the eyes.

Green Tea and Eye Health

Until recently, the catechins in green tea have been thought to only offer some protection for the eyes against UV rays; however, a new animal study published in the Journal of Agricultural and Food Chemistry suggests that eye structures of rats absorb significant amounts of individual catechins, especially the retina, which absorbs the highest levels of gallocatechin. The results of the study also show that the catechins in green tea reduce harmful oxidative stress in the eye for up to 20 hours. The results of this new study lead researchers to believe drinking green tea may promote eye health in humans by reducing the risk of developing glaucoma and other eye diseases.

Other Benefits of Catechins

Belonging to the same family of antioxidants that includes vitamins C and E, lutein, and zeaxanthin, the catechins found in green tea is well-known for its ability to help the body fight free radical damage and certain age-related diseases. In addition to possibly promoting eye health in humans, studies show catechins can lower the risk of heart disease, lower high blood pressure and high cholesterol, may reduce the risk of certain cancers, and aids weight loss.

How Much Green Tea?

Does green tea promotes good eye health

Green tea typically contains 150 to 200 milligrams of catechins, but until a study is conducted on humans in the area of green tea and eye health, it’s unclear how much of this powerful antioxidant is needed to boost eye health. Experts do, however, recommend consuming at least two to three cups of green tea per day to gain the greatest health benefits.

Although results of this most recent study look promising, further research is needed to confirm these same types of findings in humans.
