1. Anti-aging effect of Tieguanyin Some scientific studies at home and abroad show that human aging is related to the over-oxidation of unsaturated fatty acids in the body, and the over-oxidation of unsaturated fatty acids is related to the action of free radicals. Free radicals with high chemical activity can over-oxidize unsaturated fatty acids, make cell function mutate or decline, cause tissue proliferation and necrosis, and produce fatal diseases. Lipid over-oxidation is the devil of human health, but the culprit is free radicals. As long as the free radicals are removed, cells can get normal growth and development and live a long and healthy life. Usually, the 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.
II. Anti-cancer effect of Tieguanyin Cancer is an "incurable disease" that seriously threatens people's health today. Therefore, in recent years, the study of tea anti-cancer has aroused great interest and concern. A few years ago, there was a report 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, it has been recognized by the world that drinking tea can prevent and fight cancer, and Tieguanyin has the best anti-cancer effect in tea. As early as 1983, Professor Tuonan Okuda of Okayama University in Japan screened dozens of plant polyphenols for their anticancer effects. The results showed that catechins (EGCG) had strong anticancer activities. Other scientists believe that Tieguanyin tea polyphenols are the main active components in the study of confirming Tieguanyin's anti-mutation. In the study of chemical carcinogenesis, the preventive effect of Tieguanyin tea polyphenols was affirmed. In addition, vitamin C and vitamin E in Tieguanyin can block the synthesis of nitrosamines, a carcinogen, which plays a great role in the prevention and treatment of cancer.
III. Anti-arteriosclerosis effect of Tieguanyin On May 31, 1999, at the fourth oolong tea and health seminar held in Tokyo, Japan, Vice President Chen Ling of Fujian Institute of Traditional Chinese Medicine reported that they had taken 25 patients with hyperlipidemia and obesity as clinical observation objects to explore the effect of drinking Tieguanyin oolong tea on inhibiting the oxidation of low-density lipoprotein in blood and improving blood lipid metabolism. 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 improve 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 investigation of 18 farmers in Anxi Tea Township, Fujian Province in 1974, the research group of coronary heart disease prevention and treatment of Fujian Medical University found that the incidence of not drinking Tieguanyin tea was 3.1%. Occasionally drinking is 2.3%; Drinking all the year round (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.
iv. the preventive and therapeutic effect of tieguanyin on diabetes mellitus is a worldwide disease. At present, about 2 million people in the world suffer from diabetes, and more than 3 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 being weak all over. This disease is called "diabetes" in Chinese medicine, which belongs to the category of scorching damp heat. The main reason for getting sick is the lack of polyphenols in the body, such as vitamin B1, pantothenic acid, phosphoric acid, methyl salicylate, etc., which makes the sugar metabolism disorder, the blood sugar in the body increases sharply, and the metabolic effect is weakened. Japanese medical doctor Ogawa Takechiro and other clinical experiments have confirmed that drinking tea regularly can supplement vitamin B1, pantothenic acid, phosphoric acid, methyl salicylate and polyphenols in human body in time, and 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's slimming and bodybuilding effect Obesity 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 a lot of inconvenience to people's daily life, but also causes cardiovascular diseases and diabetes.
