Tea contains catechins, cholestene, caffeine, inositol, folic acid, pantothenic acid and other ingredients, which can improve human health, improve body immunity, and enhance physical fitness. Tea is known as "one of the three major beverages in the world" and is the "mental health care agent" for our human beings.
Here are some questions about tea:
Q: I want to lose weight, what tea should I drink?
Answer: Weight loss is suitable for drinking oolong tea such as Tieguanyin and raw Pu'er tea.
1. In human fat cells, the energy that is not consumed is stored as neutral fat for use as energy during exercise. At this time, under the action of enzymes such as protein-like lipase, neutral fat is decomposed into necessary energy for use. Drinking oolong tea can enhance the function of protein-like lipase. That is to say, it is not that oolong tea itself can dissolve fat, but it can improve the enzymes that break down fat. Therefore, after drinking oolong tea, the amount of fat metabolism is also relatively increased, which has the effect of losing weight.
2. Tea polyphenols and their oxidation products in Pu-erh tea (raw tea) can dissolve fat and promote the excretion of lipids, thus reducing the levels of total cholesterol, free cholesterol, low-density lipoprotein cholesterol and triglycerides in the blood. content, thereby reducing cholesterol deposition on the arterial vessel wall and reducing the incidence of arterialization. It can also activate protein kinases, accelerate the decomposition of fat, and reduce the fat content in the body. Scientists have found through human experiments that compared with people who drink ordinary water, the daily energy consumption of tea drinkers is 67eal higher on average, and the fat oxidation rate is higher than 12%. This proves that Pu-erh tea does have a lipid-lowering and weight-loss effect.
Q: I often get angry, what tea should I drink to get rid of the fire?
Answer: Tieguanyin has the effect of clearing heat and reducing fire. Tea is a good drink for preventing heatstroke and cooling down. Li Shizhen's "Compendium of Materia Medica" contains: "Tea is bitter and cold, ... it can reduce fire the most, fire is a hundred diseases, and when fire is lowered, it becomes clear. ... Warm drink will reduce fire due to cold, while hot drink will rise and disperse through fire. "In the dog days of midsummer, when the sun is shining and the heat is overwhelming, drinking a cup of cool Tieguanyin or a cup of hot Tieguanyin will make you feel cool in body and mind, and relieve the heat. This is because the tea soup contains tea polyphenols, sugars, amino acids, pectin, vitamins, etc., which chemically react with the saliva in the mouth to moisten the mouth, so it can play a role in promoting body fluid and quenching thirst. At the same time, due to the effect of caffeine in Tieguanyin, a large amount of energy is released from the skin pores of the human body. According to reports, drinking a cup of hot tea, the heat emitted by sweating through the pores of the human skin is equivalent to 50 times that of this cup of tea, so it can make people feel cool and relieve the heat.
Q: What kind of tea can you drink to resist oxidation and delay aging?
A: Black tea (Yunnan Dianhong), white tea and dark tea (Pu'er tea) all have anti-aging effects:
1. The U.S. government has funded more than 150 studies on green and black teas and their chemical constituents, and the findings show that the antioxidants in green and black tea can completely disrupt the spread of chemicals in cancer cells. "Black tea has roughly the same efficacy as green tea, but black tea has more complex antioxidants than green tea, especially for the heart," said Dr. Murray Mittelman, director of cardiovascular epidemiology at Beth Israel Deaconess Medical Center in Boston. . American magazine reported that black tea has stronger anti-aging effects than garlic, broccoli and carrots.
2. White tea has high-efficiency antioxidant function, which can strengthen the skin's resistance, prevent the discomfort caused by the external environment on the skin and premature aging problems, and keep the skin lasting and smooth.
3. Tea polyphenols and their oxidation products in dark tea (Pu-erh tea) can dissolve fat and promote the excretion of lipid substances, thus reducing the total cholesterol, free cholesterol, low-density lipoprotein cholesterol and triglyceride in the blood. content, thereby reducing cholesterol deposition on the arterial vessel wall and reducing the incidence of arterialization. It can also activate protein kinases, accelerate the decomposition of fat, and reduce the fat content in the body.
