Effects of Green Tea on the Brain

Probably no other natural substance has been studied more in the past few decades than green tea. It has been the subject of research projects at universities and medical facilities around the world because of it’s health benefits, and the conclusion is that it does have some amazing properties.

Green tea has been associated with everything from the treatment of skin problems and lowering cholesterol, to preventing heart disease and the effects of aging.

It is not surprising, then, that in the category of anti-aging effects, it also deals with the serious problems associated with dementia, Alzheimers, Parkinson’s disease, and stroke.

Due to the actual processing of green tea, more polyphenols or catechins are left in the tea. These antioxidants provide a large number of benefits to the body, and, they stop free radicals from damaging cells.

The star of the show when it comes to green tea is EGCG, Epigallocatechin gallate, a form of catechin, and, a potent and important antioxidant.

Epigallocatechin gallate (EGCG), also known as Epigallocatechin 3-gallate, is the ester of epigallocatechin and gallic acid and a type of catechin.

The difference between green tea and the other varieties is the fact that they have catchins. In fact, they have four times the concentration of these antioxidant catechins than black tea.

During our lifetimes, amyloid plaques, sheets of protein attack the nerve cells of the brain, actually destroying them, by depriving them of oxygen. As we age, more of these cells are destroyed, causing loss of memory, speech, and general overall motor skills. EGCG has been shown to deflect and counterattack free radicals that attack brain cells.

These findings are no great surprise to eastern cultures, who have been major supporters of green tea and it’s benefits for thousands of years.

Japanese researchers have spent years investigating the benefits of green tea on aging, the function of the brain, and memory. For the most part, their findings indicated that senior who drank several cups of green tea over a period of time, fared better in overall test results than others who did not. Black and oolong tea did not show the same findings.

Recently scientists have become hopeful that Parkinson’s disease, a condition of the nervous system may benefit as well. Polyphenols, which are actually found in all plants, have apparently been underrated, and are just now being more appreciated for what they can do. These polyphenols may be the key to the treatment of many nervous system diseases.
