Preventing cancer still remains unanswered for modern science and medicine. Green tea research is providing some answers but even more questions. Drinking tea does one thing for certain, it introduces green tea as a daily source of beneficial micro nutrients. Science has shown links between green tea catechins and flavonoids on reducing the incidence of cancerous tumors in both animals and humans. Green tea in particular has been the focus of study because greater quantities of these compounds exist in green tea and white tea. Black tea and oolong tea still contain many of the same beneficial components, but they have not received as much attention or study. The compounds of most interest within green tea are called polyphenols also known as tea tannins. The best known is Epigallocatechin Gallate (EGCG). Other green tea polyphenols with similiar properties are Epicatechin, Epigallocatechin, and Epicatechin Gallate. Research conducted by the National Cancer Center in Tokyo suggests about tens cups of green tea per day for the prevention of cancer. Especially for people with high risk of stomach, intestine, colon or liver cancer. Cancer research also suggests that green tea polyphenols can inhibit the pathways of developing cancer cells.
One mechanism of tumor production may involve oxidative damage to cells by free radicals. Drinking green tea "mops" up these free radical and helps safely pass them through the body with out causing cell damage. Carcinogens are introduced throughout the digestive system mainly from the foods we eat. Smoking, food additives and pesticides make up the majority of the harmful carcinogens we consume, but they also exist in foods that are smoked, pickled, fermented, or contain small amount of mold from products containing grain, wheat, corn or, rye. Green tea’s rich supply of antioxidants may also play a key role in the prevention of other cancers, like breast, and lung cancer. While the potential anti-cancer properties of green tea look promising, they are also complex and not yet completely understood. Antioxidants are best consumed in loose tea. Take the time to prepare and enjoy a nice cup of tea. There are many extracts and pills on the market today, but as with any product, capitalists have tried to bottle this healthy beverage and this process removes any of the health benefits.
