Misconceptions about drinking tea that are ignored

　　Everyone has drank tea, but not everyone necessarily understands the misunderstandings about drinking tea. For everyone’s health, we still have to pay attention to some misunderstandings about drinking tea. Let’s take a look now!

　　1. Like to drink new tea: Because new tea has a short storage time, it contains more unoxidized polyphenols, aldehydes, alcohols and other substances, which have a strong stimulating effect on human gastrointestinal mucosa. It is easy to induce stomach problems, so you should drink less new tea, and avoid drinking new tea that has been stored for less than half a month.

　　2. Drink Toubian tea: Since tea is contaminated by pesticides and other harmful substances during cultivation and processing, there are always certain residues on the surface of tea leaves. Therefore, Toubian tea has a cleansing effect and should be discarded.

　　3. Drink tea on an empty stomach: Drinking tea on an empty stomach can dilute gastric juice, reduce digestive function, and increase the absorption rate when adding water, causing a large amount of undesirable components in the tea to enter the blood, causing symptoms such as dizziness, palpitation, and weakness in hands and feet.

　　4. Drink tea after meals: Tea contains a large amount of tannic acid. Tannic acid can react with the iron in food to form new substances that are difficult to dissolve. Over time, it can cause iron deficiency in the human body and even induce anemia. The correct way is: drink tea one hour after a meal.

　　5. Drink tea when you have a fever: Tea contains theophylline, which has the effect of raising body temperature. Drinking tea for patients with fever is like "adding fuel to the fire."

　　6. Patients with ulcers drink tea: The compounds in tea can promote gastric acid secretion, increase gastric acid concentration, induce ulcers and even perforation.

　　7. Drinking tea during menstruation: Drinking tea during menstruation, especially strong tea, can induce or aggravate menstrual syndrome. Medical experts have found that compared with those who do not drink tea, those who drink tea are 2.4 times more likely to suffer from menstrual stress, and those who drink more than 4 cups of tea a day are three times more likely to suffer from menstrual stress.
