It is not good to eat fruit after meals. Traditional habits believe that eating fruit after meals is a good eating habit. However, recent studies have found that this view is not scientific. Eating fruits after meals will have adverse effects on digestive function. Fruit eaten after a meal is easily blocked in the stomach by the food eaten first, causing symptoms such as flatulence and constipation. It will also affect the digestion and absorption of food and have adverse effects on digestive function. In addition, it is not appropriate to eat fruits before meals, as this will affect people's normal food intake, and the human intestines and stomach cannot fully absorb the nutrients in the fruits. The most reasonable time to eat fruit should be between meals, usually between 9-10 am in the morning and 3-4 pm in the afternoon. If your meal times are irregular, try to limit your fruit eating time to 1 hour before meals and 2 hours after meals. In addition, some fruits should not be eaten on an empty stomach or at the same time as oily foods. For example, persimmons contain tannins, which solidify when exposed to acid and form "persimmon stones", which can easily lead to "stomach stones". In general, fruits should be eaten raw, and the fresher they are, the more nutritious they are. But if you are a critically ill patient, you can also cook it and eat it
