When a child experiences diarrhea, their gastrointestinal function is clearly disordered. They have absorption dysfunction, meaning the nutritional substances they consume are not easily absorbed. There may even be a bacterial infection in the intestines, leading to inflammatory exudation and consequently, a noticeable increase in the frequency of bowel movements and watery stools. If the child consumes cold fruits during this period, it could aggravate the diarrhea. Therefore, if parents need to give fruits to a child with diarrhea, they should choose fruits like apples or oranges and serve them warm. Other fruits, such as bananas, could increase gastrointestinal motility and thus worsen the symptoms of diarrhea. During a diarrhea episode, it is important to select appropriate fruits and avoid cold foods.
