When you have a fever, you must eat less melon seeds and not more, because melon seeds are easy to get on fire when you eat too much. As saliva secretion and gastrointestinal activity are weakened when you have a fever, the secretion of digestive enzymes, stomach acid, bile and other secretions are correspondingly reduced, and digestion is poor. At this time, you should eat liquid food that is easily absorbed, such as white porridge, minced meat porridge, noodles, thin rice, and egg congee with easily digestible food, such as mackerel. The diet must be light, eat easily digestible food, and oil and salt must be consumed in small amounts. Usually eat small amounts of meals, avoid spicy and stimulating foods, but do not have to avoid eating to prevent malnutrition and decreased resistance.
