A few days ago, the influence of drinking tea for a long time on the proportion and distribution of body fat content pointed out a ray of dawn for many people who are trying to get rid of waist and abdomen fat. Dr. Wu Zhixing pointed out in his research that tea extract may enhance the generation of heat energy, promote fat oxidation and 24-hour heat consumption rate, stimulate fat hydrolysis, and inhibit the activity of pancreatic lipolytic enzymes, thus affecting the body's fat mass.

The results show that people who have long-term tea drinking habits (drinking tea at least once a week for more than half a year 1 time) will have significantly less body fat content and abdominal fat than those who have never drunk tea.

In Japan, I especially like oolong tea in China. Because oolong tea has a strong role in decomposing fat, it can help solve greasy, help digestion and lose weight. Dr. Carobbi, clinical director of St. Anthony's Department of Medicine, confirmed that drinking Pu 'er tea produced in Yunnan often can reduce triglycerides and cholesterol in the human body. French women, especially young women, attach great importance to physical beauty. They call Pu 'er tea "slimming tea". French doctors experimented with Pu 'er tea. Each subject drank three cups of Pu 'er tea every day for one month. As a result, some people lost weight, and some people lost their blood lipids. French doctors also experimented with Yunnan Tuocha on 40 obese men and women, asking them to drink a cup of Tuocha every morning and evening. After continuous use for one month, more than 40% have lost weight to varying degrees. This is also one reason why French people like to drink Yunnan tea.

Second, drinking tea can prevent tooth decay.

Drinking tea or brushing your teeth with tea can not only eliminate bad breath, but also prevent dental caries? #653 10; Dacheng Zhou, MD, Beijing Stomatological Hospital. In the 1990s, we began to study the efficacy of tea in preventing dental caries, such as drinking tea, gargling with tea soup, brushing your teeth, or using toothpaste containing tea leaves, but brushing your teeth with tea soup is the best. This is because tea contains fluorine, which has great affinity with calcium in teeth, and can become a kind of "neon apatite" which is difficult to dissolve in acid? #653 10; Add a protective layer to toad teeth to improve their ability to prevent acid and caries? Nbsp Using tea to prevent caries is one of the ways to protect teeth. Therefore, gargling, brushing teeth and drinking tea with tea soup can be popularized among children. In low fluorine areas, it is recommended to drink ordinary low-grade tea (high-grade tea and famous tea have low fluorine content) to prevent dental caries. Drinking tea soup brewed with10g of tea every day can meet the human body's demand for fluorine. Tea with high fluorine content includes Fujian oolong tea, Yunnan tea, Yunnan black tea, Zhejiang tea, Jiangxi jasmine tea and Guizhou brick tea.

Third, tea can prevent cardiovascular diseases.

Drinking tea is beneficial to cardiovascular diseases such as hypertension. Coronary heart disease has certain preventive and therapeutic effects. Clinical experiments have proved that people who drink three bowls of Tuocha every day for a month have reduced their blood lipid by 13% and cholesterol. Clinical trials were conducted on 80 patients with hypertension. As a result, after 5 days of treatment with green tea, the blood pressure of 30 patients decreased and some people returned to normal. Some people also study the relationship between drinking tea and coronary heart disease, which is divided into three groups: no drinking tea, occasional drinking tea and frequent drinking tea. The results showed that the incidence of coronary heart disease was 3.65438 0% without drinking tea, 2.3% with occasional drinking tea and 65438 0.4% with frequent drinking tea. We can see the effect of drinking tea on preventing coronary heart disease.

Fourth, tea is a good medicine for intestinal diseases.

Zhang Zhongjing, a medical sage, said, "Tea is very effective in treating purulent blood." Modern medical research has confirmed that tea is a good medicine for treating intestinal diseases. Polyphenols in tea can solidify and precipitate protein. Tea polyphenols combined with single-celled bacteria can coagulate eggs and kill bacteria. Such as harmful cholera bacteria, typhoid bacilli, Escherichia coli and so on. Soak in strong tea soup for a few minutes, and most of them will lose their ability to move. Therefore, Chinese medicine and folk often use strong tea or ground green tea to treat intestinal diseases such as bacillary dysentery and enteritis. The method is that 3 grams of tea leaves and a bowl of water are decocted three times a day; Or three times a day, a cup of strong tea and 20 ml of vinegar; You can also take tea 15g and shepherd's purse flower 15g, decocted and taken three times a day before meals. Secondly, when making tea with water, if the drinking water is not clean, the tea leaves can adsorb impurities in the water and precipitate them, which has the function of purification and disinfection and is good for preventing intestinal infectious diseases.
