As the national drink of our country, green tea is rich in nutrients and is a very healthy drink. Especially, the content of vitamin C in green tea is higher than that in other teas. Because green tea does not ferment, it can better maintain the content of vitamin C.

Green tea is also rich in nutrients such as catechin, vitamin E and-carotene. Catechin is a natural antioxidant, which can scavenge free radicals in the body, protect cell health and play an anti-aging role. In addition, catechins can also improve the metabolic capacity of fat, reduce the accumulation of fat in the body and protect the health of blood vessels.

At the same time, caffeine, dietary fiber and vitamin E in green tea can lower cholesterol level, protect blood vessels and prevent arteriosclerosis. Caffeine in green tea stimulates the central nervous system of the brain and plays an awakening role. Therefore, I don't recommend that you drink strong tea before going to bed. It may affect normal sleep.

Research shows that caffeine can stimulate the secretion of gastric juice, help food digestion, and relieve the greasy feeling caused by high-fat food. However, it should be noted that it is best to drink green tea 3 minutes after meals instead of immediately.

As we said earlier, green tea has many health benefits, but there are three kinds of people who are not suitable in daily life.

1. Green tea can sober up, and people with neurasthenia and poor sleep quality should not drink it.

Caffeine in tea can promote the secretion of gastric acid, and patients with gastric ulcer may get worse after drinking it.

3. Because caffeine in green tea may affect the development of fetus and young children, it is not recommended for pregnant women and lactating women to drink tea.

the last type of people are people who take medicine every day. Because the alkaline substances in tea are easy to combine with some substances in drugs to form precipitation, it will not only affect the absorption of normal nutrients, but also affect the absorption of drugs, with slow efficacy and poor effect. Green tea is called "national drink", and it is better to drink it often, but please pay attention to the following three kinds of people not to leave, so tea is a good thing, but pay attention when drinking. It is best for these three kinds of people not to drink.
