The appearance of the six tea families gradually changed from green to yellow-green, yellow, green-brown and black, and the tea soup gradually changed from green to yellow-green, yellow, green-brown and reddish-brown.
Green tea: green leaves are cold, clear and annoying.
From the point of nutritional value, green tea has not been fermented, and the natural substances in tea are well preserved. Vitamins, chlorophyll, tea polyphenols, amino acids and other nutrients are the most abundant in all tea leaves. Green tea can clear away heat, eliminate irritability, enhance thinking ability and improve immunity. It is most suitable for busy young people, mental workers and people who often face computers, while green tea is cool and not suitable for people who get angry or get angry easily at ordinary times.
White tea: Huangbai decoction can lower blood sugar.
When processing white tea, only the tender tea leaves with fluff on the back are dried or dried with slow fire, so that the white fluff can be completely preserved. Its fermentation degree is between 10-20%, and it belongs to lightly fermented tea.
White tea is most suitable for diabetics, because white tea is not fried and kneaded in the processing process, and the polysaccharide contained in tea is basically not destroyed. Tea polysaccharide has a certain effect on treating diabetes. In addition, white tea is cool and refreshing, and has the functions of reducing fire, removing dryness and treating constipation. However, when diabetics drink white tea, it is best to soak it in low-temperature boiling water at about 80℃ for 4 to 6 hours, and drink it in the morning and evening. It is not allowed to brew with boiling water, so as not to destroy tea polysaccharide at high temperature.
Yellow tea: yellow leaf yellow soup helps digestion
Yellow tea is characterized by "yellow leaves" and "yellow soup". In fact, it is the product of fried green tea. In the process of frying green tea, the process of suffocating yellow was added to make yellow tea. The fermentation degree of yellow tea is between 20-30%, which belongs to micro-fermented tea.
Yellow tea needs to be stuffy, which belongs to "retting tea". A large number of digestive enzymes are produced in the process of retting tea, which is good for the spleen and stomach, so people with indigestion, loss of appetite or obesity are most suitable for drinking. However, yellow tea contains more caffeine and tea polyphenols, which is easy to make people feel excited and increase the amount of urination, so it is not suitable for the health of expectant mothers and fetuses, and it is easy to cause pregnancy poisoning, so it is not suitable for pregnant women to drink.
Green tea: bodybuilding tea with green leaves and red edges.
Green tea, also known as oolong tea, is a semi-fermented tea with a fermentation degree of 30-60%, that is, a kind of tea between green tea and black tea when its leaves are slightly red after proper fermentation in the production process.
Green tea is best for obese people. Because of its good effects of lowering blood fat, cholesterol and helping digestion, it is called "beauty and bodybuilding tea" in Japan. In addition, oolong tea has a refreshing effect, which is suitable for students who study hard at night or those who stay up late to work overtime. All people who drink green tea should be careful not to drink on an empty stomach, otherwise they will not only feel hungry, but even some people will feel dizzy and sick, that is, they will get drunk after drinking tea. In addition, it is best for pregnant women not to drink alcohol, in which theophylline has an exciting effect, which will increase fetal movement and be unfavorable to the fetus.
Black tea: thick black and brown should not be thin.
The raw materials of black tea are coarse and old, and the fermentation degree reaches 100%. During the processing, after a long period of accumulation and fermentation, the leaves are dark brown. Therefore, it is called black tea, which belongs to post-fermented tea and is mainly consumed by ethnic minorities in the border areas.
Black tea is most suitable for people who always like to eat meat, because its tea is warm and has obvious effects of removing greasy, fat and blood fat. However, black tea contains a lot of tea polyphenols and caffeine. It has an effect on fetal growth and is contraindicated by pregnant women.
Black tea: Tang Hong warms the spleen and stomach.
In China, black tea is the second largest tea after green tea. Both dry tea and brewed tea soup are red, so they are called black tea. The fermentation degree of black tea can reach 80-90%, which belongs to fully fermented tea.
Black tea is warm, the tea soup is sweet, non-irritating, and has the function of regulating the spleen and stomach. In foreign countries, it is customary to add milk and sugar to the tea soup of black tea, which can supplement nutrition and increase body heat energy. For people with poor stomach or weak body, green tea is not suitable, and black tea is more suitable. Black tea is warm, so it is not suitable for people who get angry or get angry easily at ordinary times.
