Green Tea may Help Protect Against Glaucoma

by Sreeraman on February 20, 2010 at 9:10 AM Diet & Nutrition News

Green tea contains healthful substances that can penetrate eye tissues, raising the possibility that the tea may protect against glaucoma and other eye diseases, say researchers.

Scientists have confirmed the benefits of green tea in ACS's bi-weekly Journal of Agricultural and Food Chemistry.

Chi Pui Pang and colleagues point out that so-called green tea "catechins" have been among a number of antioxidants thought capable of protecting the eye. Those include vitamin C, vitamin E, lutein, and zeaxanthin. Until now, however, nobody knew if the catechins in green tea actually passed from the stomach and gastrointestinal tract into the tissues of the eye.

Pang and his colleagues resolved that uncertainty in experiments with laboratory rats that drank green tea. Analysis of eye tissues showed beyond a doubt that eye structures absorbed significant amounts of individual catechins. The retina, for example, absorbed the highest levels of gallocatechin, while the aqueous humor tended to absorb epigallocatechin. The effects of green tea catechins in reducing harmful oxidative stress in the eye lasted for up to 20 hours.

"Our results indicate that green tea consumption could benefit the eye against oxidative stress," the report concludes.
