A study by Professor Nicholas Tangshan of the Center for Preventive Medicine in Paris, France, shows that compared with people who don't drink tea, the risk of death of people who love tea is reduced by 24%. An antioxidant experiment in Britain shows that a cup of 300ml tea has the same antioxidant effect as 1.5 bottles of red wine (about 750ml per bottle), 12 bottles of white wine, 4 apples, 5 onions or 7 cups of fresh orange juice. Jiang Yongwen, deputy director of the Tea Research Institute of the Chinese Academy of Agricultural Sciences, said that human aging is a slow "oxidation" process, so everyone needs anti-oxidation. Tea has a strong antioxidant capacity, and the habit of drinking tea every day can effectively solve the anti-aging problem. He emphasized that tea has six major benefits, namely, anti-cancer, anti-radiation, anti-oxidation, lowering blood pressure, lowering blood fat and lowering blood sugar. Epidemiological studies in Japan show that compared with people who drink less than 3 cups of tea a day (30 ml per cup), the risk index of cardiovascular disease in men who drink a small cup of 10 tea a day is reduced by 42%, while that in women is reduced by 18%. Green tea retains the most polyphenols and has the best antioxidant effect. However, tea polyphenols can cause irritation to the stomach. People with chronic gastritis and gastric ulcer had better drink less green tea, and black tea can be used instead. Tea contains a small amount of caffeine, which is not suitable for people with unstable sleep and bad heart. Don't drink tea before going to bed and on an empty stomach. It is recommended to drink tea after meals 1 hour. You can put 3~5 grams of green tea in a teacup, and soak each gram of tea in 50 ml of boiling water for 3~5 minutes, and then soak it for three or four times.
