Precautions for drinking tea:

1, don't drink tea immediately after eating meat.

Protein, which is rich in meat, can react with tannic acid in tea to generate new substances, which will affect the peristalsis of human intestine, thus prolonging the retention time of feces in the intestine. Especially those who have eaten pork, dog meat, mutton and donkey meat think that drinking tea at this time can clear the stomach and relieve boredom, but they don't know that it can clear the stomach and easily cause constipation.

2, patients with liver disease avoid drinking tea.

Caffeine and other substances in tea are mostly metabolized by the liver, which is sick. Drinking too much tea exceeds the metabolic capacity of the liver and will damage the liver tissue.
