Health benefits of Green Tea


Health benefits of Green Tea will make you amazed that how this green tea component can deliver power house of antioxidant. the most well known is green tea's benefit for weight loss. It helps speed up the metabolism, and reduces appetite, both of which are deeply appreciated by dieters everywhere. Green tea also helps regulate insulin levels, which mean less cravings when you're on a diet (or even when you're not!).

Green tea is particularly rich in health-promoting flavonoids (which account for 30% of the dry weight of a leaf), including catechins and their derivatives. The most abundant catechin in green tea is epigallocatechin-3-gallate (EGCG), which is thought to play a pivotal role in the green tea's anticancer and antioxidant effects. Catechins should be considered right alongside of the better-known antioxidants like vitamins E and C as potent free radical scavengers and health-supportive for this reason.

There are several benefits that green tea offer. I am listing few to make you younger, dynamic and glowing.

It improves Cardio health
Green tea mainly promotes heart health via its benefits for cholesterol. Green tea reduces overall cholesterol, and in particular, levels of the 'bad' cholesterol. It blocks the absorption of cholesterol in the intestines, by up to 89%. And it increases the elimination of cholesterol in the feces; protects the liver from the effects of high cholesterol; and reduces the conversion of low-density lipoproteins (LDL - building block for the 'bad' cholesterol) into sticky, artery-clogging plaque.

The heart health benefits of green tea may be lost somewhat in all the talk about how green tea helps with weight loss, but they are significant.

Green Tea fights against Cancer
Green tea extract is rich in antioxidants, such as ECGC, that kill cancer cells and prevent their growth without harming healthy tissue. Consumption of this extract is especially beneficial to patients suffering from breast, lung, skin, liver, bladder, pancreatic, stomach or prostate cancer.

Antioxidant Slows down the Aging Process

The antioxidants present in green tea extract are responsible for slowing down the aging process of the body. This helps you look younger.

Improves your Immune System
Green tea has shown promise in treating anogenital warts, inhibiting the replication of the adenovirus and the influenza virus (both cold and flu viruses), as well as increasing the effectiveness of antibiotics up to three times, without producing any side effects. The studies on the cold and flu viruses were done in a lab, and not on people, and as such are considered preliminary studies.

However the other studies were done on people. It is believed the theanine in tea boosts the immune system, though there are also other constituents of green tea that benefit the immune system. It was the catechins in green tea (in particular one called sinecatechin) that were tested in the study on warts, and other studies have shown that another catechin, EGCG, works in the same way that some antibiotics do in regard to bacteria.

One cup of green tea contains about 200 mg of catechins. And it should be steeped in hot water for at least 5 minutes, preferably 15 minutes for those wishing to use green tea medicinally.

Lowers Cholesterol and Blood Pressure
Green tea extract helps to lower the LDL (bad) cholesterol that’s responsible for clotting of blood. The extract helps prevent strokes and heart attacks. It promotes the production of HDL (good) cholesterol that removes the plaque in the arteries and keeps them elastic. This lowers your risks of suffering from heart disease. Persons suffering from hypertension also benefit by consuming green tea extract, because it lowers blood pressure.

Green Tea Prevents Tooth Decay
Some studies also showed that green tea’s ability to destroy bacteria can also actually put a stop to dental plaque. Good oral health is very important to a person’s overall well-being and health, after all.
