After food enters the stomach, it must go through the digestion process of 1 ~ 2 hours before it can be discharged slowly. If you eat fruit immediately after a meal, it will be blocked in the stomach by the food that arrives in advance, so that the fruit can not be digested normally in the stomach, and staying in the stomach for too long will cause symptoms such as bloating, diarrhea or constipation. If we persist in this lifestyle for a long time, it will lead to digestive dysfunction.
