Investigators have pointed out that compounds donning a crucial part for several of the health advantages of green tea are able to permeate the tissues present in the eyes and have anti-oxidant activities.
Since long green tea has been plugged for several advantages to health which encompass being capable of combating cardiovascular ailments and cancer, with all due regard to green tea’s elevated concentrations of ailment-combating antioxidant presence known as catechin.
Investigators have stated that catechin is amongst several antioxidants, inclusive of vitamin E, zeaxanthin, vitamin C and lutein that have been believed to assist in safeguarding the fine tissues present in the eyes from eye conditions like glaucoma and several others. However, several studies conducted till date has not been able to show that catechin present in green tea was able to be taken in by the tissues present in the eyes.
Glaucoma is the prevailing reason for sightlessness in the U.S. afflicting over two million of its adults. Damage due to glaucoma is irreversible and has since long been known as ‘the robber of eyesight’ as it could lead to considerable eye harm prior to the problem being detected.
An added heath advantage of Green Tea
Investigators of a research that was printed in the ‘Journal of Agricultural and Food Chemistry’ indicated that varied components of the eye were observed to absorb different quantities of catechins.
In the course of the study, researchers had been feeding lab rodents extracts of green tea. The eye tissues of these rodents were then examined by the researchers.
The outcomes revealed that retina; the light-sensitive tissue lining the backside of the eye had the maximum catechin concentration. The outer-placed, clear eye layer, cornea was that part having the lowest amount of catechin absorbed.
The study additionally revealed that a computation of antioxidant activity endured for almost twenty hours following intake of green tea extract.
Investigators Kai On Chu from the dept. of Ophthalmology and visual sciences, Chinese Univ. of Hong Kong along with associates stated that the study outcomes indicate that consuming green tea could safeguard the eyes. Additional research would still be necessary for corroborating a safeguarding outcome on human beings.
