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, and it is a semi-fermented tea with transparent amber tea juice as its characteristic. But in fact, oolong tea is just a general term, which can be subdivided into many different types of tea. For example: Narcissus, Bai Mudan, Tieguanyin (suitable for seafood) and so on.

Wu Shu's "Tea Fu" in the Song Dynasty said: "It is wonderful for a husband to use tea milk to cleanse his troubles and quench his thirst, and move his bones to strengthen his body."

First, prevent cancer.

1June, 998 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 of the Chinese Academy of Preventive Medicine, and her assistant Xu Yong conducted an anti-cancer experiment on tea in animals. They fed mice five kinds of tea, such as Anxi Tieguanyin, and at the same time, they were fed synthetic carcinogen methyl carbazide glue 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. Among Tieguanyin in Anxi, five teas have the best anticancer effect. 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 nitrosoguanidine in vivo. Transfer from Gaoshan Tea Network

Second, reduce blood lipids.

198 1 year, a male professor from Toyomami Kawamura, Miyagawa, Japan and a foreign women's university conducted an experiment on the effect of oolong tea on animal fat metabolism, which proved that oolong tea can significantly inhibit the increase of cholesterol and neutral fat in blood. From 65438 to 0983, Fujian Institute of Traditional Chinese Medicine observed a group of patients with hypercholesterolemia. Under the condition of stopping all kinds of lipid-lowering drugs, they drank oolong tea twice every morning and evening, and after 24 weeks of continuous use, the blood cholesterol content of patients decreased to varying degrees. Further animal experiments show that oolong tea can prevent and relieve atherosclerosis of main arterial blood lipids. Drinking oolong tea can also reduce blood viscosity, prevent erythrocyte aggregation, improve blood hypercoagulability, increase blood fluidity and improve microcirculation. This is very 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.

Third, anti-aging

The anti-aging experiments conducted by Fujian Institute of Traditional Chinese Medicine from 65438 to 0983 showed that the lipid peroxidation in the liver of two groups of animals fed with oolong tea and vitamin E respectively decreased significantly, which indicated 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. 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 Professor Wang Zenong once wrote a poem during his inspection in Anxi Tea Township, which highly summarized the health care efficacy of Anxi Oolong Tea: Anxi is as fragrant as Tieguanyin, and six roots prolong life. Huang Jingui, a newly selected famous tea, is a panacea to protect Dan's heart. Long-term service for thousands of years is beautiful. It can cure all diseases and is very light.
