Tea includes green tea, black tea and so on. From the health care effect, green tea is the best.

1. Green tea contains the most abundant nutrients needed by human body, such as protein, vitamins and trace elements. Although determined, the iron content per 100g green tea is 40mg, which is 8 times higher than that of hawthorn/kloc-0 and 29 times higher than that of grape. Drinking 10g green tea every day can get 30% iron needed by physiology. It also contains a lot of zinc. People who drink green tea regularly can get 30 mg of zinc every day, which is more than those who don't drink 16 mg. As for manganese, which has unique advantages in preventing diseases such as osteoporosis and skin itching, green tea is also the most abundant.

Second, green tea contains some special disease-resistant ingredients, such as antidiabetic substances, which can lower blood sugar, promote insulin secretion and help diabetic patients recover, while black tea contains very little.

Third, there are the least harmful elements. Take aluminum for example. According to the test, tea is an aluminum-loving plant, which can absorb a lot of aluminum in the soil, especially black tea, with the highest aluminum content, which can reach 7.2-7.5 mg per ml of soaking solution, while green tea is much less.

Therefore, whether men, women and children drink tea, green tea should be the first choice.
