IBS should eat low-fat, low-sodium, high-vitamin, high-protein foods, such as apples, strawberries, grapes, etc., but should be careful not to eat too cold fruit. IBS patients can eat apples and other fruits rich in vitamin C, which is conducive to the recovery of gastroenteritis, but also can eat more grapes, blackcurrants, strawberries and other fruits rich in anthocyanins, these fruits in the anthocyanins can remove the free radicals in the body, but also can alleviate the various discomforts of gastroenteritis symptoms. Secondly, it is not recommended that patients with gastroenteritis eat too cold fruits, such as fruits just taken out of the refrigerator, because patients with gastroenteritis have inflammation in the intestinal tract, and eating too cold fruits will stimulate the gastrointestinal tract, which will aggravate the patient’s condition. If the patient’s gastroenteritis symptoms are serious, he should go to the hospital in time, and give standardized treatment after clarifying the cause.
