1. Avoid drinking tea after meals. Tea leaves (mainly green tea) contain a large amount of tannic acid, which can react with iron in food to form new substances that are difficult to dissolve. Over time, it will cause iron deficiency in the human body and even induce anemia. Therefore, the correct drinking time is: one hour after meals.

2. Avoid drinking tea with fever. Tea contains theophylline, which has the effect of raising body temperature. Drinking tea for fever patients is tantamount to "adding fuel to the fire".

3. Ulcer patients should not drink tea. Caffeine in tea can promote gastric acid secretion, increase gastric acid concentration, induce ulcers and even perforation.

4. Avoid drinking tea during menstruation. Drinking tea during menstruation, especially strong tea, can induce or aggravate menstrual syndrome.

5. Avoid drinking new tea. The new tea has a short storage time and contains a lot of unoxidized polyphenols, aldehydes and alcohols, which has a strong stimulating effect on the human gastrointestinal mucosa and is easy to induce gastric diseases. Therefore, new dark teas should be drunk less, and new teas that have been stored for less than half a month should be avoided.

6. Don't drink tea for the first time. Tea has been contaminated by pesticides and other harmful substances in the process of cultivation and processing, and there are always certain residues on the surface of tea leaves. Therefore, the first time tea has a cleansing effect and should be discarded.

7. Avoid drinking tea on an empty stomach. Drinking tea on an empty stomach can dilute gastric juice and reduce digestive function. At the same time, the high water absorption rate can cause a large amount of bad ingredients in tea to enter the bloodstream, causing symptoms such as dizziness, palpitation, and weakness of hands and feet.
