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.
antibiosis

Green tea contains flavonol, which has antioxidant effect, prevents thrombosis and platelet aggregation, and reduces cardiovascular diseases.

Disadvantages:
1, green tea is easy to oxidize and difficult to preserve. Tea polyphenols in green tea are strong antioxidants, so it is easy to nourish itself. Although the reason why tea polyphenols can make people live longer is still inconclusive, the tea brewed from oxidized old tea is coffee red, without tea fragrance, and the taste is greatly deteriorated.
2. Most people drink tea weakly and are not used to strong tea. Therefore, for the sake of health, the amount of tea they drink is insufficient.
3. Beware of "urea tea". What is "urea tea"? A few years ago, there was demand for tea, and tea farmers in some places had "technological innovation". After picking tea every morning, spray urea solution on the tea tree in the afternoon, and the tea will grow very long the next morning. This cycle leads to a sharp increase in tea production. Therefore, when drinking tea, we must recognize the brand and the quality, and we must not be greedy and cheap.
