Eight functions of green tea
1. Green tea anti-aging
Antioxidants contained in green tea help to fight aging. Because in the process of human metabolism, if it is over-oxidized, it will produce a lot of free radicals, which are easy to age and cause cell damage. SOD (Superoxide Dismutase) is a kind of free radical scavenger, which can effectively remove excess free radicals and prevent the harm of free radicals to human body. Catechins in green tea can significantly improve SOD activity and scavenge free radicals.
2. Green tea is antibacterial
Studies have shown that catechins in green tea can inhibit some bacteria that cause human diseases without harming the proliferation of beneficial bacteria in the intestine, so green tea has the function of whole intestine.
3. Green tea lowers blood fat
Animal experiments made by scientists show that catechins in tea can reduce total cholesterol, free cholesterol, low-density lipoprotein cholesterol and triglycerides in plasma, and at the same time increase high-density lipoprotein cholesterol. Human experiments show that it can inhibit platelet aggregation and reduce the incidence of arteriosclerosis. Green tea contains flavonol, which has antioxidant effect, prevents thrombosis and platelet aggregation, and reduces cardiovascular diseases.
