There are many foods that should not be consumed during a fever caused by a cold, such as spicy foods including chili peppers, black pepper, mustard, onions, ginger, and garlic. Avoid these items, as well as fried foods, foods high in fat, overly sweet foods, and overly sour foods, for example, fried foods, pork belly, pig head meat, or some candies, creams, cheeses, and pastries. Furthermore, attention should also be given to avoiding carbonated drinks, alcoholic beverages, strong tea, and coffee. The diet should be light with the option to consume things like millet porridge, vegetable porridge, or some freshly squeezed juices to provide vitamins and enhance body resistance, helping to expedite recovery from cold and fever symptoms. During a fever, it is important to monitor body temperature. If it exceeds 38.5°C, fever-reducing medication should be taken; otherwise, physical cooling methods can be sufficient.
