Green tea refers to a product made from the new leaves of the tea tree, which is unfermented and undergoes typical processes such as fixing, rolling, and drying. The color of the finished product and the tea soup after brewing largely preserve the main green tone of fresh tea leaves. Green tea has many benefits, which are roughly as follows:
1. Weight loss and fat reduction: Green tea contains theophylline and caffeine, which can activate protein kinase and triglyceride lipase through various effects, reduce fat cell accumulation, and thus achieve a weight-loss effect.
2. Prevents cavities and freshens breath: Green tea contains fluoride, and its catechins can inhibit the action of cariogenic bacteria, reducing the occurrence of dental plaque and periodontitis. The tannic acid in tea has a bactericidal effect, which can prevent food debris from breeding bacteria, so it can effectively prevent bad breath.
3. Cancer prevention: Green tea has an inhibitory effect on certain cancers, but its mechanism is still at the stage of inference. Drinking more tea certainly has a positive encouraging effect on preventing cancer.
4. Whitening and UV protection: Experts found in animal experiments that catechins in green tea can resist skin cancer caused by UV-B.
5. Can improve indigestion: Studies show that green tea can help improve indigestion. For example, for acute diarrhea caused by bacteria, drinking a little green tea can alleviate the condition.
