Don’t drink tea immediately after eating.
The act of drinking tea immediately after eating will impact food digestion by diluting stomach juice. Meanwhile, tannic acid in the tea can make protein in the food as the solidified non-digestible material to increase the burden on the stomach and affect the absorption of the protein. Tea is rich in tannin, which prevents the absorption of iron in the intestine by combination reaction with the iron in food; the combination of tannin and protein makes tannin protein with the role of convergence, slowing down the intestinal peristalsis, thereby it extends the retention time of stool in the intestine which will not only cause constipation, but also increase the possibility of carcinogens and toxic substances absorbed by the body, so do not drink tea immediately after eating, in particular, do not drink strong tea immediately.
