Gastrointestinal colds are caused by Coxsackie virus infection. Patients can eat more vegetables and fruits to supplement plant-based fiber and hydrate. Eating nutritious foods such as beef and mutton can help replenish energy and enhance resistance. Staple foods should be soft, such as rice soup, noodle soup, and vegetable soup. It is important to note that spicy and irritating foods should be avoided, and the consumption of strong tea, coffee, and alcohol should be minimized during the cold.
