What are the benefits of drinking green tea? First of all, we need to understand the ingredients of green tea. Modern scientific research has confirmed that green tea contains more than 450 kinds of organic compounds and more than 15 kinds of inorganic minerals. Most of these ingredients have health care and disease prevention effects. 1. Reduce fat and lose weight, and prevent cardiovascular and cerebrovascular diseases. There is a very close relationship between tea drinking and weight loss. The book "Shen Nong's Materia Medica" mentioned the weight loss effect of tea as early as more than 2,000 years ago: "Long-term use will calm your mind and replenish your qi... you will lighten your body and not grow old." Modern scientific research and clinical experiments have confirmed that drinking tea can reduce blood lipids and cholesterol in the blood and make the body lighter. This is because the phenolic derivatives, aromatic substances, amino acids, and vitamins in the tea are comprehensively coordinated As a result, especially the combined effect of tea polyphenols, tea pigments and vitamin C can promote fat oxidation, help digestion, reduce fat and lose weight. In addition, tea polyphenols can dissolve fat, and vitamin C can promote the excretion of cholesterol from the body. Green tea itself contains tea ganine, which improves the toughness of blood vessels and makes them less likely to rupture. A study published in the American Heart Association's "Circulation" magazine in May 2002 showed that regular tea drinking can help reduce the risk of death from heart disease. Researchers at Harvard Medical School in the United States conducted a follow-up survey on 1,900 heart disease patients. These patients were mainly elderly people over 60 years old. The survey results found that those patients who drank an average of more than 14 cups of tea per week had lower The risk of death about three and a half years after a heart attack was 44% lower than those who didn't drink tea. Research also shows that even patients who drink less than 14 cups of tea per week on average are likely to reduce heart disease mortality by 28%. 2. Prevent cancer. The ingredients contained in green tea - tea polyphenols and caffeine, the combined effect of the two not only refreshes and nourishes the mind, but also has the effect of improving human immunity and anti-cancer. In recent years, the American Chemical Society has discovered that tea not only has inhibitory effects on digestive system cancers, but also on skin, lung, and liver cancers. Scientific research has confirmed that the organic anti-cancer substances in tea mainly include tea polyphenols, theophylline, vitamin C and vitamin E; the inorganic anti-cancer elements in tea mainly include selenium, molybdenum, manganese, germanium, etc. Chinese and Japanese scientists believe that catechins in tea polyphenols have the best anti-cancer effect. 3. Anti-toxic and sterilization. The use of tea as a good detoxification medicine can be traced back to the ancient Shennong era (about 2737 BC). "Shennong tasted hundreds of herbs, encountered seventy-two poisons every day, and got tea to relieve them." This is said in "Historical Records? III" It is recorded in books such as "Huang Ben Ji", "Huainanzi Xiu Wu Xun", and "Compendium of Materia Medica". Tea sage Lu Yu pointed out in his "The Book of Tea", the world's first authoritative book on tea more than 1,200 years ago (780 AD), about the "Efficacy of Tea": "Because tea is extremely cold in nature, it is most suitable for use as a tea. Beverages... If you feel body heat, thirst, nausea, brain pain, tired eyes, tired limbs, or joint discomfort, drinking four or five sips of tea will be effective." The above symptoms listed by Lu Yu are very close to typical pneumonia or suspected cases. Chen Zangqi, a medical scientist in the Tang Dynasty, wrote in "Supplementary Materials of Materia Medica": "Quenches thirst and eliminates epidemics. Tea is also expensive." The famous eunuch Liu Zhenliang also listed "using tea to remove malaise" as one of the tea virtues in his "Ten Virtues of Tea". Since the Tang Dynasty, tea therapy in the past dynasties has also had new descriptions of tea detoxification and sterilization. However, due to the underdeveloped science at that time, highly contagious and epidemic diseases were collectively called "plague" or "disease", although they were not specifically mentioned. It is not clear what kind of bacteria or viruses they are, but it has been confirmed that drinking tea can help fight viruses and sterilize them. The modern medical community has continued to conduct in-depth research on the health-care effects of tea. In 2003, American scientists reported in the Proceedings of the National Academy of Sciences: "The chemical substance called 'theanine' in tea can increase the body's ability to resist infection by five times." .
