The popularity of oolong tea is entirely due to its slimming effect of dissolving fat, and this statement does have scientific basis. Because tannic acid, the main component of tea, is proved to be closely related to fat metabolism, and the experimental results also confirm that oolong tea can really reduce the cholesterol content in the blood, which is really a rare slimming tea. As we all know, oolong tea is the representative of China tea, which is a kind of semi-fermented tea, and the transparent amber tea juice is its characteristic. But in fact, oolong tea is just a general term, and it can be subdivided into many different types of tea. For example: Narcissus, Bai Mudan, Tieguanyin, which is suitable for seafood, and so on. There are many kinds, so you can choose from them. Experiments have proved that drinking one liter of oolong tea every day can inhibit the rise of cholesterol. Although the amount of drinking should be determined according to each person's physical condition, when the food is too greasy, it is best to match oolong tea, which not only makes you feel full, but also removes greasy food. The health-care function of oolong tea: tea works like a god, which has long been known. Lu Quan, a poet in the Tang Dynasty, described the efficacy of tea in this way: "A bowl of throat is moist, two bowls are lonely and boring, and three bowls are impoverished, with only 5,000 volumes of words; Four bowls of light sweat, life is unfair, and it is scattered to the pores; Five bowls of clear skin; Six bowls of fairy spirits; Seven bowls can't be eaten; I only feel the breeze in my armpits. \ "Song Dynasty Wu Shu's" Tea Fu "said: \" It's wonderful for a husband to cleanse his annoyance and cure his thirst, change his bones and make him fit, and benefit from tea ru. Li Shizhen's Compendium of Materia Medica in the Ming Dynasty said: \ "Tea is bitter and cold, and the yang in the yin will sink and fall, which can best reduce the fire. \ "Oolong tea is a special famous tea in China. It has been confirmed by modern scientific research at home and abroad that Oolong tea not only has health care functions such as refreshing mind, relieving fatigue, promoting fluid production and diuresis, relieving fever and preventing diseases, sterilizing and diminishing inflammation, detoxicating and preventing diseases, promoting digestion and removing boredom, losing weight and keeping fit, but also has special functions such as preventing cancer, reducing blood fat and resisting aging. 1. Cancer Prevention1June, 1998 15 "Health News" (Reporter Zheng Yuanxiang) reported that not long ago, Han Chi, an associate researcher in the Toxicology and Chemistry Research Office of the Institute of Nutrition and Food Hygiene, Chinese Academy of Preventive Medicine, and her assistant Xu Yong conducted a cancer inhibition test of tea in animals. They fed rats five kinds of tea, such as Anxi Tieguanyin, and at the same time, they were fed synthetic carcinogen methyl carbazide gum with purity greater than 99.8%. After three months, the incidence of esophageal cancer in rats was 42-67%, and the average number of tumors in rats with cancer was 2.2-3. However, the incidence of esophageal cancer in rats who did not drink tea was 90%, and the average number of tumors in mice with cancer was 5.2. The five kinds of tea had the best anti-cancer effect in Anxi Tieguanyin. At the same time, they also conducted another experiment, that is, using sodium nitrite and methyl carrageenan as carcinogenic precursors. The results showed that none of the rats in the tea drinking group developed esophageal cancer, and the incidence rate in the tea drinking group was 100%. This result proves that tea can completely block the endogenous formation of nitrosgum in vivo. Transferred from Gaoshan Tea Network II, Reducing Blood Lipids 198 1 year, a male professor from Miyagawa Toyomami and Kawamura, Japan, conducted an experiment on the effect of oolong tea on animal fat metabolism, which proved that it could significantly inhibit the increase of cholesterol and neutral fat in blood. 1983, Fujian Institute of Traditional Chinese Medicine observed a group of patients with high blood cholesterol. Under the condition of stopping all kinds of lipid-lowering drugs, they drank oolong tea twice a day in the morning and afternoon, and after 24 weeks in a row, the blood cholesterol content of patients decreased to varying degrees. Further animal experiments show that oolong tea can prevent and alleviate the atherosclerosis of blood lipids in main arteries. Drinking oolong tea can also reduce blood viscosity, prevent erythrocyte aggregation, improve blood hypercoagulability, increase blood fluidity and improve microcirculation. This is important for preventing vascular diseases, intravascular thrombosis and traditional Chinese medicine? quot; Blood stasis has positive significance. In addition, in vitro thrombosis test also shows that oolong tea has the effect of inhibiting thrombosis. Anti-aging 1983, the anti-aging experiment conducted by Fujian Institute of Traditional Chinese Medicine showed that the lipid peroxidation in the liver of two groups of animals fed with oolong tea and vitamin E respectively decreased significantly, which showed that oolong tea had the same anti-aging effect as vitamin E. Human experiments also show that drinking oolong tea can keep the content of vitamin C in blood at a high level and reduce the excretion of vitamin C in urine, and the anti-aging effect of vitamin C has long been proved by research. Therefore, drinking oolong tea can enhance the anti-aging ability of human body in many ways. 1985 10 when professor Wang Zenong visited Anxi tea town, he wrote a poem, which highly summarized the health care efficacy of Anxi oolong tea: Anxi is as fragrant as Tieguanyin, and its longevity is prolonged by six roots. Huang Jingui, a newly selected famous tea, can be called a panacea to protect Dan's heart. Long-term service for thousands of years is beautiful, and it can cure all diseases and is light. It is well known that drinking tea has many benefits. But why does drinking tea have many benefits? For the average person, this is knowing it but not knowing why. With the development of science, the composition of tea industry was gradually clarified in the early19th century. After modern scientific separation and identification, oolong tea contains more than 450 kinds of organic chemical components and more than 40 kinds of inorganic mineral elements. Organic chemical components and inorganic mineral elements in tea contain many nutrients and medicinal components. Organic chemical components mainly include: tea polyphenols, plant alkaloids, protein, amino acids, vitamins, pectin, organic acids, lipopolysaccharides, sugars, enzymes and pigments. Tieguanyin contains organic chemical components, such as tea polyphenols, catechins and various amino acids, which are significantly higher than other teas. Inorganic mineral elements mainly include: potassium, calcium, magnesium, cobalt, iron, manganese, aluminum, sodium, zinc, copper, nitrogen, phosphorus, fluorine, iodine and selenium. Tieguanyin contains more inorganic mineral elements such as manganese, iron, fluorine, potassium and sodium than other teas.
