The green tea is right to prevent the invalid _'s prevention and health care of gastric carcinoma
New York, February 28 (Reuter's medical news) Contrary to result of study in the past, a result of study released on Wednesday indicates to drink the green tea invalid to preventing gastric carcinoma. This research was led by Dr. Yoshitaka Tsubono of Japan Tohoku university medical college. The researchers study the following in 8 years about 26,000 men and women, the result shows, drink the green tea, regardless of quantity, have no special-effect to the health. Takeshi Sano and Dr. Mitsuru Sasako of the state-run cancer central hospital of Tokyo point out in the relevant comment: "Like, drink people of green tea, can continue, keep habit this, don't expect, drink green tea, can lower emergence risk of gastric carcinoma. " Result of study and comment are published on March " medical magazine of New England ". In the whole world, the mortality of gastric carcinoma occupies the second of different mortality of cancer at present. In near these decades, the incidence of gastric carcinoma is dropping progressively, this may be refrigerated because fresh vegetables and fruit in the food are increasing mainly and pickled the food to reduce. But in Japan, no matter gender, gastric carcinoma still occupies the first place in reason of causing death of cancer, probably 18% cancer relevance death is caused by gastric carcinoma. The past several research showed, the content against oxidant was relatively high in the green tea, can prevent cells from damaging and can prevent cancer. Other research brief on too, green tea can prevent gastric carcinoma, the intersection of pancreas and cancer, the intersection of bladder and cancer and cancer of colon. However, if you want to reach the above-mentioned result, the green tea that people drink every day will be up to 10 cups, and will obviously increase the intaking amount of the caffeine while doing it in this way. Some people substitute and drink the green tea by taking green tea extract capsules every day. The researchers have carried on the investigation in living in rural area, man and women above the age of 40 of Japan, have mainly investigated these people drink the quantity of the green tea every day. About 40% of the people drink the green tea in above 5 cups every day, 19% of the people drink the green tea under a cup every day. In the course of the follow-up investigation, 419 people diagnose, suffer from gastric carcinoma, but researcher find emergence of gastric carcinoma and have any relation between the the intersection of green tea and quantity not drunk. This prospective research (researchers will continue carrying on the follow-up investigation to the crowd be studied) Than surveying already patient with cancer of past research (always reviewing) More scientific in terms of research approach. In retrospect research, the drink consumption that patients who has already suffered from gastric carcinoma may reduce the green tea, so may be inaccurate to the retrospect that drank the situation of the green tea in the past, thus will make the result of study offset. One of the authors of this research, Dr. Chung-Cheng Hsieh of the medical center of University of Massachusetts points out: "Though this research is reasonable in design and the performance is better, but this is only one group in a large number of data eventually, we need to carry on further intervention research and could draw the final conclusion.
