1, sun protection. Recently, a study in the United States pointed out that catechins in green tea have strong antioxidant function. Skin care products containing green tea can reduce about 1/3 of peroxides that cause sunburn, relaxation and roughness of the skin even after being exposed to the sun. This proves that the ingredients in green tea have sunscreen function.

2. Radiation protection. For 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 makes eyes see things more clearly in dark light. So green tea can not only eliminate computer radiation, but also protect and improve vision.

3. Reduce blood fat. Drinking tea can lower blood fat and cholesterol and make the body lighter. This is because the comprehensive coordination of phenolic derivatives, aromatic substances, amino acids and vitamins in tea, especially the comprehensive function of tea polyphenols, theanine and vitamin C, can promote fat oxidation, help digestion and reduce fat and weight.

4. Prevent bad breath. Green tea contains fluorine, in which catechins 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 residues from breeding bacteria, so it can effectively prevent bad breath.
