I. Anti-aging Effect of Tieguanyin Some scientific studies at home and abroad show that human aging is related to the peroxidation of unsaturated fatty acids in the body, and the peroxidation of unsaturated fatty acids is related to the action of free radicals. Free radicals with high chemical activity can make unsaturated fatty acids over-oxidized, make cell function mutate or decline, cause tissue proliferation and necrosis, and produce fatal diseases. Lipid peroxidation is the devil of human health, but the culprit is free radicals. As long as free radicals are removed, cells can grow and develop normally, and live a long and healthy life. Commonly used antioxidants are vitamin C and vitamin E, which can effectively prevent the over-oxidation of unsaturated fatty acids. Recently, Japanese researchers have shown that polyphenols in Tieguanyin can prevent excessive oxidation; Purine alkaloids can indirectly scavenge free radicals, thus achieving the purpose of delaying aging.

2. Anti-cancer effect of Tieguanyin Cancer is an "incurable disease" that seriously threatens people's health. Therefore, in recent years, the anti-cancer research of tea has aroused great interest and concern. A few years ago, it was reported that the esophageal cancer of Shanghai residents decreased year by year because of drinking tea, so the fact that drinking tea can prevent cancer caused great repercussions all over the world. Nowadays, drinking tea to prevent cancer has been recognized by the world, and Tieguanyin is the best anticancer effect in tea. As early as 1983, Professor Tuonan Okuda of Okayama University in Japan had screened out the anticancer effects of dozens of plant polyphenols. The results showed that catechin (EGCG) had strong anticancer activity. Another scientist believes that Tieguanyin tea polyphenols are the main active ingredient in the study of confirming Tieguanyin's anti-mutation. In the study of chemical carcinogenesis, the preventive effect of Tieguanyin tea polyphenols has been affirmed. In addition, vitamin C and vitamin E in Tieguanyin can block the synthesis of nitrosamines, which plays a great role in the prevention and treatment of cancer.

Three. Anti-arteriosclerosis Effect of Tieguanyin 1999 On May 3 1, at the 4th Symposium on Oolong Tea and Health held in Tokyo, Japan, Vice President Chen Ling of Fujian Academy of Traditional Chinese Medicine reported that they took 25 patients with hyperlipidemia and obesity as clinical observation objects to explore the effects of drinking Tieguanyin Oolong tea on inhibiting the oxidation of low-density lipoprotein in blood and improving lipid metabolism in blood. Studies have proved that tea polyphenols and vitamins in Tieguanyin can inhibit the oxidation of low-density lipoprotein in blood. Dr. Masahiko Hara of Mitsui Institute of Agriculture and Forestry in Japan has also confirmed in many years' research that tea polyphenols can not only reduce cholesterol in blood, but also significantly increase the ratio of high-density lipoprotein to low-density lipoprotein in blood. Caffeine can relax blood vessels, speed up breathing, reduce blood lipids, and has a certain effect on the prevention and treatment of cardiovascular and cerebrovascular diseases such as coronary heart disease, hypertension and arteriosclerosis. According to the survey of farmers in Anxi Tea Township 1080 of Fujian Medical University, the incidence of not drinking Tieguanyin tea is 3. 1%. Occasionally drinking alcohol is 2.3%; Drinking for more than 3 years is 1.4%.

It can be seen that people who often drink Tieguanyin have lower incidence of coronary heart disease than those who don't drink Tieguanyin.

Tie Guanyin's prevention and treatment of diabetes is a worldwide disease. At present, about 200 million people in the world suffer from diabetes, and more than 30 million people in China suffer from diabetes. Diabetes mellitus is a chronic progressive disease with disorder of glucose metabolism. The typical clinical manifestations are "three more and one less", that is, drinking more, urinating more, eating more and wasting away, and feeling weak all over. This disease is called "diabetes" in Chinese medicine and belongs to the category of hot and humid heat. The main cause of the disease is the lack of polyphenols in the body, such as vitamin B 1, pantothenic acid, phosphoric acid, methyl salicylate and so on. , make the glucose metabolism disorder, the blood sugar in the body rises sharply, and the metabolism is weakened. The clinical experiments of Nana Ogawa Takeichiro, a Japanese doctor of medicine, confirmed that drinking tea regularly can replenish vitamin B 1, pantothenic acid, phosphoric acid, methyl salicylate and polyphenols in human body in time, which can prevent the occurrence of diabetes. For patients with moderate and mild diabetes, blood sugar and urine sugar can be reduced to very little or completely normal; For patients with severe diabetes, it can reduce blood sugar and urine sugar and relieve various main symptoms.

5. Tieguanyin is a nutritional disorder accompanied by the continuous improvement of people's living standards, which is caused by excessive nutrient intake or insufficient use of energy stored in the body. Obesity not only brings inconvenience to people's daily life, but also causes cardiovascular diseases and diabetes.
