There are also quite a few foods that should not be eaten during acute gastroenteritis. Firstly, spicy foods should be avoided, as the digestive function of the intestines is somewhat limited during gastroenteritis, and spicy foods can easily irritate the gastrointestinal tract, worsening the symptoms of gastroenteritis. Additionally, foods that are too cold or too hot should not be consumed. It is also advisable to avoid the stimulation of strong tea, coffee, and hard liquor. Instead, eat soft, easily digestible foods, consume less greasy food, and make sure to drink plenty of water. This helps to replenish fluids and prevent dehydration symptoms that might arise from gastroenteritis.
