It is recommended to drink tea one hour after eating bananas, because bananas are rich in many vitamins and trace elements, especially bananas are rich in potassium ions and sugar of glucose. Therefore, eating bananas can replenish the lack of ions in the body and the blood sugar lost in the body, and also quickly replenish the vitamins and trace elements, which are fast-acting energy supplements. If you drink tea immediately after eating bananas, theophylline and tea polyphenols in tea will have certain chemical reactions with potassium ions in bananas, which will prevent or reduce the bioavailability of potassium ions. Reduce the absorption of nutrients in bananas, such as the degree of vitamin absorption, and will also cause a certain burden on the gastrointestinal tract. Therefore, it is recommended to drink tea after an hour interval after eating bananas, and the concentration of tea should not be too high.
