Efficacy and function of green teaDrinking green tea often has many benefits. According to the latest report of British "Reuters News Network", a large-scale new Japanese study published in American Journal of Clinical Nutrition found that the elderly who often drink green tea are more flexible and independent than other elderly people. The effects and functions of green tea are as follows:
1. Sun protection
Recently, a study in the United States pointed out that catechins in green tea have a strong antioxidant function. After skin care products containing green tea are applied to the skin, even if they are exposed to the hot sun, the peroxides that cause sunburn, relaxation and roughness of the skin can be reduced by about 1/3. This proves that the ingredients in green tea have sunscreen function.
2. Radiation protection
For the busy people, the easiest way to resist computer radiation is to drink 2 ~ 3 cups of green tea and eat an orange every morning. Because tea is rich in provitamin A, it can be quickly converted into vitamin A after being absorbed by the human body. Vitamin a can synthesize rhodopsin, which can makeeyeYou can see things better in dim light. Therefore, green tea can not only eliminate computer radiation, but also protect and improve eyesight.
3. Reduce blood fat
Drinking tea can reduce blood lipids and cholesterol, and make the body lighter. This is because of the comprehensive coordination of phenolic derivatives, aromatic substances, amino acids and vitamins in tea, especially the comprehensive effect of tea polyphenols, theanine and vitamin C, which can promote fat oxidation, help digestion, reduce fat and lose weight.
4. Anti-halitosis
Green tea contains fluorine, in which catechin can inhibit the action of cariogenic bacteria and reduce the occurrence of dental plaque and periodontitis. Tannic acid contained in tea has bactericidal effect, which can prevent food scraps from breeding bacteria, so it can effectively prevent bad breath.
5. Anti-aging
Antioxidants contained in green tea help to resist aging. Because of the process of human metabolism, if it is over-oxidized, it will produce a lot of free radicals, which will easily age and cause cell injury. SOD (Superoxide Dismutation) is a free radical scavenger, which can effectively remove excess free radicals and prevent the damage of free radicals to human body. Catechins in green tea can significantly improve SOD activity and scavenge free radicals.
6, antibacterial
Studies have shown that catechins in green tea can inhibit some bacteria that cause human diseases, and at the same time, it will not harm the proliferation of beneficial bacteria in the intestine, so green tea has the function of whole intestine. Studies have shown that tea polyphenols can eliminate excessive harmful free radicals in the body, and can regenerate efficient antioxidant substances such as α-VE, VC, GSH and SOD in the human body, thus protecting and repairing the antioxidant system, which has significant effects on enhancing the body’s immunity, preventing cancer and preventing aging.
7, prevent stomach trouble
A study shows that drinking more green tea can prevent chronic gastritis and gastric cancer. The study found that the longer people drink green tea, the lower the rate of chronic gastritis and gastric cancer, and the rate of gastric cancer of people who love green tea is 48% lower than that of people who don’t like tea.
8. Cancer prevention
Green tea can inhibit some cancers, but its principle is limited to the inference stage. Drinking more tea is bound to have a positive encouraging effect on preventing the occurrence of cancer.
9. Promote digestion
Recent research reports show that green tea can help improve indigestion, such as acute diarrhea caused by bacteria, and drinking a little green tea can alleviate the condition.
Experts specially remind: the fresher the tea, the better. Nutritionally speaking, the nutrients of the freshest tea are not necessarily the best, because the so-called new tea refers to the tea that has been picked for less than a month. Because these tea leaves have not been placed for a period of time, some substances that have adverse effects on the body, such as polyphenols, alcohols and aldehydes, have not been completely oxidized. If you drink new tea for a long time, you may have uncomfortable reactions such as diarrhea and abdominal distension.
