It is not good to eat fruits immediately after meals for the following reasons: 1. Fruits contain more sugar, glucose, fructose, sucrose, starch, etc. Eating fruits immediately after meals will increase the burden of gastrointestinal digestion and absorption as well as the digestive burden of the pancreas, especially after eating less ripe fruits, which contain higher starch, leading to an increased burden on digestive function. 2. Fruits are rich in cellulose, pectin and other components, which Have a strong water absorption, absorb water and swell, can increase the feeling of fullness after meals, making people feel uncomfortable, and the content of cellulose in fruits is larger, they can adsorb electrolytes, trace elements and organic acids in the intestine, delaying and reducing the absorption of certain nutrients and vitamins. And certain less ripe fruits contain certain tannic acid, such as bananas, which combine with trace elements in the eaten food, such as iron and calcium, to form more insoluble substances, and prevent the body from absorbing them. If you eat fruit immediately after a meal, it will lead to the above-mentioned adverse reactions, and a long time will affect the normal human digestion and absorption function. It is best to eat fruits 1-2 hours after meals, otherwise the fruits eaten after meals will be retained in the stomach, which will also cause the fruits to rot in the stomach and intestines in the long run, producing too much gas and aggravating the patient’s abdominal distension and diarrhea, so it is not advisable to eat fruits immediately after meals.
