Substance In Green Tea Shown To Boost Brain, Aid Weight Loss

Green tea has long been a favorite of holistic health advocates. Now a new scientific study shows that the brew may have powerfully positive effects on three major health issues.

A new study published by the Federation of American Societies for Experimental Biology suggests that green tea may prevent loss of memory, battle obesity and help the brain absorb insulin.

Specifically, a substance in green tea called EGCG – which is epigallocatechin-3-gallate – is what drives the positive effects. EGCG is what scientists call a “catechin,” a natural plant metabolite long been known to be an antioxidant. It is abundant in green tea leaves.

The study was performed on mice. Three groups were used. One group was fed a standard diet, a second group was given a HFFD (high fat and fructose) diet and a third had a HFFD diet supplemented with EGCG. The diets were monitored over 16 weeks.

The result was that Group Two gained the most weight on the HFFD diet. They had higher weights than the mice who ate ordinary food, clearly showing that high fat and high fructose diets contribute to weight gain. But Group Three ate HFFD while also taking the green tea extract and still lost weight.

Furthermore, the mice that got green tea supplements soundly outperformed the other mice in maze tests, suggesting much better brain function.

It is known that a high fat and fructose diet also weakens the brain’s ability to absorb insulin. The mice that got a lot of fat and sugar supplemented with green tea were able to overcome the negative effects of this bad diet by showing efficient uptake of brain insulin.

Researchers say this hard science adds credibility to the widespread belief that green tea is an extremely healthy beverage for the brain and weight management.
