Making Green Tea a regular part of one's everyday diet provides an overall feeling of well-being and is associated with various health benefits. Green tea is only partially fermented and hence the greenish color of the leaves is retained. Green teas are pale yellowish-green in color when freshly prepared and give a delicate taste. Green tea, being one of the richest sources of antioxidants called Polyphenols help in neutralizing the harmful effects of free radicals in the body. Free Radicals are the chemical molecules which are formed naturally in the body due to exposure to pollution, sunlight, stress and regular metabolic activities of the body. Medical research has indicated that the presence of excess of such free radicals in the body is the cause of various health disorders.

Studies indicate that adults in Japan who consumed higher quantities of green tea had longer life span and the death rates caused due to Cardiovascular diseases etc., were reduced significantly. In comparison to all other teas, green tea, in particular has been found to contain Polyphenols that prevent Cardiovascular and Chemo-preventive agents.

They are believed to prevent Colon Cancer, Pancreatic Cancer, Lung Cancer, breast cancer and skin cancer. Green Tea is also recommended as a nutritional supplement for individuals suffering from Cancer. Apart from being devoid of any sort of negative side-effects, it contains strong anti-cancerous properties. Green Tea has proven benefits that help prevent skin cancer in particular. The Centre for Disease Control in the US has diagnosed skin cancer as the most common form of cancer in the US, and apart from avoiding sun exposure, regular use of sunscreen and regular examinations by dermatologist, consumption of green tea which has antioxidant, antitumour and antibacterial properties is recommended by dermatologist. Also research indicates that Epigallocatechin Gallate, which is a component found in Green Tea, inhibits the DNA damage that occurs due to exposure to ultraviolet rays.
