" Tea polyphenols are the general name of phenolic substances and their derivatives in tea, and they are also the main components of tea, among which "catechins" account for about 70% of the total polyphenols. Green tea is one of the most abundant catechins in tea, because it can better preserve chlorophyll and vitamins that are easily destroyed by high temperature without fermentation. Catechin, β-carotene, vitamin C and vitamin E have miraculous effects on scavenging free radicals, delaying aging and preventing cancer. It can prevent cell gene mutation, inhibit the growth of malignant tumor, reduce blood fat and blood pressure, prevent cardiovascular diseases, prevent colds and tooth decay, and eliminate halitosis. At the same time, green tea also has a soothing effect. Caffeine contained in green tea is different from caffeine contained in coffee, because when it coexists with catechin, it can prevent the function of caffeine in the stomach and avoid stimulating the secretion of gastric acid, so that the disadvantages of caffeine are not exerted in the body, but the functions of promoting the central nervous system, heart and liver can be skillfully preserved.
