3. Reduce blood fat, lose weight, soften human blood vessels and prevent cardiovascular diseases.
Black tea has good effects of degrading fat, resisting blood coagulation, promoting fibrinogen dissolution, relaxing the blood vessel wall and increasing the effective diameter of blood vessels, thus inhibiting the formation of atherosclerotic plaques on the inner wall of aorta and coronary artery, thus achieving the purposes of lowering blood pressure, softening blood vessels and preventing and treating cardiovascular diseases.
The General Hospital of the Chinese People's Liberation Army observed 55 old cadres with hyperlipidemia in 1990. After taking black tea 180 days (3g a day) continuously, the blood lipid content in 50 cases decreased obviously. Epidemiological investigation in key consumption areas of Fuzhuan tea such as Xinjiang, Inner Mongolia and Qinghai shows that drinking black tea for a long time has a good regulatory effect on human blood lipid, blood sugar, blood pressure and arteriosclerosis, and has a good regulatory effect on body weight and body shape.
Anhua black tea is called by the Japanese? Slimming tea? , Koreans call it? Beauty tea? Southeast Asians call it? Slim healthy tea? . Anhua black tea has become healthy? Three highs? The preferred drink. 4. Anti-oxidation, anti-aging and longevity.

Black tea is not only rich in antioxidant substances, such as catechins, tea pigments, flavonoids, vitamin C, vitamin E, vitamin D, carotene, etc., but also contains a large number of trace elements with antioxidant effects, such as zinc, manganese, copper and selenium.

It can also significantly reduce triglyceride and low-density lipoprotein in animal serum, increase high-density lipoprotein in serum, and significantly inhibit ACE enzyme, with antihypertensive effect.
7. Improve carbohydrate metabolism, lower blood sugar and prevent diabetes.
The results showed that the content of tea polysaccharide in black tea was the highest, and its component activity was stronger than other teas. This is because in fermented tea, sugar chains and peptide chains with short phase length are formed due to the action of glycosidase, protease and hydrolase. Short peptide chains and longer peptide chains are easier to be absorbed and have stronger biological activity. Therefore, this long-dead fermented tea, especially Anhua black tea polysaccharide, has a better hypoglycemic effect than other teas.
