Green Tea Health

The reason Green tea & White Tea have more polyphenol antioxidants than other teas is because of the way they are processed. Preventing the degradation of cell membranes by neutralizing the spread of free radicals (which occurs during the process of oxidation). The health benefits of these teas are derived from the light processing of the leaves which maintain the ingredients like Catechin that research is now demonstrating to be beneficial. White & Green tea are often steamed or pan fired rather than being semi-fermented (oolong) or fermented (black tea). Fermentation leaches out some of these beneficial ingredients in the same way that frying food tends to reduce nutrient value that steaming does not. It should be no surprise that steamed green tea also maintains more of its polyphenol antioxidant profile than pan-fired green tea as well.

If green tea proves to be helpful for preventing colon cancer, this would be an added benefit for those with IBD because they are at risk for colon cancer. The healthful properties of green tea are largely attributed to polyphenols, chemicals with potent antioxidant properties. In fact, the antioxidant effects of polyphenols appear to be greater than vitamin C. The polyphenols in green tea also give it a somewhat bitter flavor. Polyphenols contained in teas are classified as catechins. Green tea contains six primary catechin compounds: catechin, gallaogatechin, epicatechin, epigallocatechin, epicatechin gallate, and apigallocatechin gallate (also known as EGCG). EGCG is the most studied polyphenol component in green tea and the most active.

Green tea also contains alkaloids including caffeine, theobromine, and theophylline. These alkaloids provide green tea's stimulant effects. L-theanine, an amino acid compound found in green tea, has been studied for its calming effects on the nervous system.
