First, the four taboo methods of drinking tea
1, avoid drinking tea because of malnutrition.
Tea has the function of decomposing fat. People who are already malnourished will be more malnourished if they drink tea to decompose fat.
2. Be careful when you are drunk.
Tea has the function of exciting the nerve center, and drinking strong tea after drunkenness will increase the burden on the heart.
Drinking tea will also accelerate diuresis, so that toxic aldehydes in alcohol will be discharged from the kidneys before decomposition, which is very irritating to the kidneys and harmful to health.
Therefore, for people with heart disease or poor function, don't drink tea, especially don't drink a lot of strong tea; For healthy people, you can drink a small amount of strong tea. When you wake up, you can eat a lot of fruit or sip vinegar to speed up human metabolism and relieve drunkenness.
3. Avoid drinking tea if you have a fever
Caffeine in tea can not only raise the body temperature, but also reduce the efficacy.
4, neurasthenia, be careful with tea.
Caffeine in tea can excite the nerve center. Drinking strong tea for neurasthenia, especially in the afternoon and evening, will cause insomnia and aggravate the condition. You can drink tea once in the morning and once in the afternoon during the day. It is better to drink scented tea in the morning, green tea in the afternoon and no tea at night. In this way, patients will be refreshed during the day, calm and comfortable at night, and can fall asleep early.
Second, people who are not suitable for drinking tea
1, children should not drink strong tea.
Because when the concentration of tea is high, the content of tea polyphenols is too high, which is easy to react with iron in food, which is not conducive to the absorption of iron and is easy to cause iron deficiency anemia in children.
Children can drink some light tea in moderation (one-third of adult tea). For preschool children, you can drink some rough tea, because the content of tea polyphenols in rough tea is low.
2. Patients with coronary heart disease should drink tea cautiously.
For coronary heart disease patients with tachycardia, premature beats or atrial fibrillation, caffeine and theophylline in tea are stimulants, which can enhance the heart function. Drinking a lot of strong tea will make the heart beat faster, which often leads to its onset or aggravation;
Therefore, such people can only drink some light tea; On the contrary, patients whose heart rate is generally below 60 beats/min should drink more tea, which is not only harmless, but also can improve the heart rate, which has the effect of cooperating with drug treatment.
3. Old people should not drink raw tea.
The so-called green tea refers to the green roasted green tea that is directly dried without twisting after being immobilized. This kind of tea has a natural green appearance, and its components are basically the same as those contained in fresh leaves. Aldehydes and alcohols with low boiling point do not transform and volatilize much, and the aroma is seriously green.
Drinking this kind of green tea for the elderly is very irritating to the gastric mucosa, and it is easy to have a stomachache after drinking; Young people will also have a feeling of stomach discomfort after drinking, which is also commonly known as "scraping the stomach."
If you buy this kind of raw tea by mistake, you'd better not make it directly. You can put it in a non-greasy iron pan, fry it slowly with slow fire, roast it to get rid of the green gas, and drink it after it produces a slight chestnut fragrance.
