2. What are the effects and functions of green tea?

1. Green tea for anti-aging

The antioxidants contained in green tea help fight aging. Because of the human body's metabolic process, if it is peroxidized, it will produce a large number of free radicals, which can easily lead to aging and cell damage. SOD (superoxide dismutase) is a free radical scavenger that can effectively remove excess free radicals and prevent free radicals from damaging the human body. The catechins in green tea can significantly increase the activity of SOD and eliminate free radicals.

2. Green tea is antibacterial

Studies have shown that the catechins in green tea have an inhibitory effect on some bacteria that cause disease in the human body, while not harming the reproduction of beneficial bacteria in the intestines. Therefore, green tea has the function of regulating the intestines. Studies have shown that tea polyphenols can eliminate excessive harmful free radicals in the body and regenerate high-efficiency antioxidant substances such as α-VE, VC, GSH, SOD, etc. in the human body, thereby protecting and repairing the antioxidant system, and have significant effects on enhancing the body's immunity, preventing cancer, and anti-aging. Drinking green tea for a long time can lower blood sugar, blood lipids and blood pressure, thereby preventing cardiovascular and cerebrovascular diseases. A medical research team at Showa University in Japan put 10,000 highly toxic Escherichia coli 0-157 into 1 ml of tea polyphenol solution diluted to 1/20 of the concentration of ordinary tea. After five hours, all the bacteria died, not a single one was left.

3. Green tea lowers blood lipids

Animal experiments done by scientists have shown that catechins in tea can lower total cholesterol, free cholesterol, low-density lipoprotein cholesterol, and triglycerides in plasma, while increasing high-density lipoprotein cholesterol. Experiments on humans have shown that it can inhibit platelet aggregation and reduce the incidence of arteriosclerosis. Green tea contains flavonoids, which could help prevent blood clots and platelet formation, and reduce cardiovascular disease.

4. Green tea helps lose weight and reduce fat

Green tea contains theanolide and caffeine, which can activate protein kinase and triglyceride lipase through many functions, reduce the accumulation of fat cells, and thus achieve the effect of weight loss.

5. Green tea prevents tooth decay and relieves bad breath

Green tea contains fluoride, and the catechins in it can inhibit the action of caries-causing bacteria and reduce the occurrence of dental plaque and periodontitis. The tannic acid contained in tea has a bactericidal effect and can prevent bacteria from breeding in food residues, so it can effectively prevent bad breath.

6. Green tea prevents cancer

Green tea has an inhibitory effect on certain cancers, but its principles are still limited to the inference stage. Drinking more tea will definitely have a positive encouraging effect on preventing cancer.

7. Green tea whitens skin and protects against UV rays

Experts have found in animal experiments that catechins in green tea can resist skin cancer caused by UV-B.
