Taboos for drinking tea:

1, like to drink new tea: because of its short storage time, new tea contains more unoxidized polyphenols, aldehydes and alcohols, which has a strong stimulating effect on human gastrointestinal mucosa and is easy to induce stomach diseases. Therefore, drink less new tea and avoid new tea that has been stored for less than half a month.

2, drinking tea on an empty stomach: drinking tea on an empty stomach will dilute the gastric juice, reduce the digestive function, and the water absorption rate is high, resulting in a large number of bad ingredients in tea entering the blood, causing dizziness, palpitation, weakness and other symptoms.

3, have a fever to drink tea: tea contains theophylline, which has the effect of raising body temperature. Drinking tea with a fever is tantamount to "adding fuel to the fire."

4, drinking tea during menstruation: drinking tea during menstruation, especially drinking strong tea, will induce or aggravate menstrual syndrome. Medical experts have found that compared with people who don't drink tea, people who have tea habits are 2.4 times more likely to have menstrual tension, and those who drink more than 4 cups of tea a day are 3 times higher.

5. Avoid drinking tea for patients with liver disease: most substances such as caffeine in tea are metabolized by the liver. If the liver is sick, drinking too much tea will exceed the metabolic capacity of the liver and damage the liver tissue.

6. Pregnant women should avoid drinking tea, especially strong tea: tea contains a lot of tea polyphenols and caffeine, which has many unfavorable factors for the growth of the fetus in the mother's womb.
