benefits of drinking oolong tea
Oolong tea contains more than 450 kinds of chemical components and more than 40 kinds of inorganic mineral elements. The organic chemical constituents and inorganic mineral elements in tea contain many nutrients and medicinal ingredients. Organic chemical components mainly include: tea polyphenols, plant alkaloids, proteins, amino acids, vitamins, pectins, organic acids, lipopolysaccharides, sugars, enzymes, pigments, and the like.
Oolong tea, semi-fermented tea and whole fermented tea, has many varieties. It is a tea category with distinctive Chinese characteristics among several large teas in China. Oolong tea evolved from the Song Dynasty and was created around 1725 (the Qing dynasty). The pharmacological effects of oolong tea are highlighted in the aspects of decomposition of fat, weight loss and bodybuilding. It is called “beauty tea” and “bodybuilding tea” in Japan. In addition to domestic sales in Guangdong and Fujian provinces, oolong tea is mainly exported to Japan, Southeast Asia and Hong Kong and Macao. The main production areas are Anxi County and other places in Fujian Province.
The organic chemical components contained in Tieguanyin, such as tea polyphenols, catechins, and various amino acids, are significantly higher than other teas. Inorganic mineral elements are mainly: potassium, calcium, magnesium, cobalt, iron, manganese, aluminum, sodium, zinc, copper, nitrogen, phosphorus, fluorine, and the like. The inorganic mineral elements contained in Tieguanyin, such as manganese, iron, fluorine, potassium and sodium, are higher than other teas.
Oolong tea has the functions of nourishing the skin, detoxifying, facilitating and anti-chemical activities, and eliminating the active oxygen molecules in the cells. Middle-aged people often drink oolong tea to help maintain hearing.
The protective effect on male hearing is significantly greater than that of females. Although drinking oolong tea has a health-care effect on hearing, it cannot be overdose. The amount of tea to drink a day is preferably 1-2 cups.
oolong tea benefits weight loss
Oolong tea has the effect of dissolving fat and losing weight. Because the main component of tea, tannic acid, is closely related to the metabolism of fat. Oolong tea can lower the cholesterol in the blood.
Compared with black tea and green tea, oolong tea can stimulate the activity of pancreatic lipolytic enzymes, reduce the absorption of sugar and fat foods, accelerate the body’s heat production, promote fat burning, and reduce the accumulation of abdominal fat.
As a special Chinese tea, oolong tea has the functions of refreshing and thinking, eliminating fatigue, urinating and digesting, antipyretic and heatstroke, sterilization and anti-inflammatory, cold and hangover, detoxification and disease prevention, digestion and detoxification, weight loss and bodybuilding. Outstanding performance in anti-cancer, hypolipidemic, anti-aging and other special effects:
On June 15, 1998, Han Chi, an associate researcher at the Institute of Toxicology and Chemistry, Institute of Nutrition and Food Hygiene, Chinese Academy of Preventive Medicine, and her assistant Xu Yong conducted a cancer suppression experiment in tea. They respectively fed five kinds of teas such as Anxi Tieguanyin to the rats, and at the same time, they were given artificially synthesized carcinogen methyl-kappa nitrosin with a purity of more than 99.8%. Three months later, the incidence of esophageal cancer in the white rats was 42-67%, and the average number of tumors in the cancer mice was 2.2-3. The incidence of esophageal cancer in rats without tea was 90%, and the average number of tumors in cancer mice was 5.2. The anticancer effect of five teas was the best in Anxi Tieguanyin. At the same time, they also conducted another test, using sodium nitrite and methyl cardamide as carcinogenic precursors. It was found that none of the rats in the tea group had esophageal cancer, and the incidence of non-tea drinking group was 100%. This result proves that tea can completely block the endogenous formation of nitrosamine gel in vivo.
Oolong tea has the effect of preventing and alleviating lipid atherosclerosis in the blood. Drinking oolong tea can also reduce blood viscosity, prevent red blood cell agglomeration, improve blood hypercoagulability, increase blood flow, and improve microcirculation. The in vitro thrombosis test also showed that oolong tea has the effect of inhibiting thrombosis.
Oolong tea has the same anti-aging effect as vitamin E. In the case of taking a sufficient amount of vitamin C daily, drinking oolong tea can keep the blood vitamin C content at a high level, and the amount of vitamin C excreted in the urine is reduced, and vitamin C has an anti-aging effect. Therefore, drinking oolong tea can enhance the body’s anti-aging ability in many ways.
three drinking taboos
Drinking oolong tea is not only good for human health, but also adds endless fun. But there are three taboos:
First, do not drink on an empty stomach, otherwise you feel hungry, dizzy and vomiting, people call it “tea drunk”;
Second, do not drink before going to bed, otherwise it is difficult to fall asleep;
Third, Do not drink cold tea which is not good for the stomach.
These three taboos are especially important for those who drink oolong tea, because oolong tea contains more tea polyphenols and caffeine than other teas.
