Benefits of Green Tea

The bioactive polyphenolic compounds found in green tea account for the benefits of drinking green tea. Its predominant polyphenols are the catechins and include epicatechin, epicatechin-3-gallate, epigallocatechin and epigallocatechin-3-gallate (EGCG).

Studies show that green tea can increase our metabolic rate and greater use of fat.

This is because the catechins in green tea inhibit the enzyme that breaks down norepinephrine (a chemical released from the sympathetic nervous system in response to stress, also referred to as a stress hormone) so that its biological effect (e.g., increased metabolic rate, increased fat breakdown, etc.) are prolonged.

Further, green tea causes a preferential use of fat over carbohydrate. A study shows that green tea is an effective in shedding fat, particularly in the mid-section. It has a great effect on reductions in subcutaneous and visceral fat in the abdomen, a region associated with higher risk for many chronic diseases.

The increased metabolic rate and greater use of fat amounted to an increase in energy expenditure ranging from 65 to 200 kcal/day. This extra fat burning translates into about 0.7 to 1.5 pounds of fat loss over a month period.

Green tea may also act to reduce food intake and inhibit the main enzymes involved in fat storage.

In addition, several lines of evidence point to green tea as an effective preventative and therapeutic agent in heart disease and cancers.

Green tea lowers cholesterol levels in the blood and is positively associated with a lower incidence of different forms of heart disease. This could be due to improved antioxidant capacity in the blood after intake of green tea and lowering of oxidized LDL. Green tea can also prevent a variety of different cancers.

And it may be used as a nutritional supplement for atherosclerosis, blood sugar control, HPV virus infection and neurodegenerative diseases.
