In the recovery period of gastroenteritis, which is just about the time, the clinical diet must pay attention to easy digestion and absorption. The focus should be on eating foods that are less stimulating to the gastrointestinal tract, such as porridge, fruits can choose bananas, for dairy products, other fruits including cold, spicy, cold food, is definitely not recommended clinically. At this time, the transition to a normal diet is generally recommended only after the intestine has recovered its function for more than a week, so the early clinical choice of food is still mainly porridge, eating light porridge, light vegetables, including noodles can be chosen. After 1-2 days of transition, other foods such as meat, easily digestible meat can be added gradually in the clinic. In general, patients can transition to a normal diet after more than a week, but of course, there are individual differences, some patients may have a faster recovery of the gastrointestinal tract, and can transition to a normal diet after 1-2 days, including eating spicy foods are not affected, but clinically it is recommended that more than a week is a safer time period.
