When you have a cold and a headache, you can certainly eat eggs. First, it's important to properly understand the cold, which is a type of self-limiting infectious disease. Clinically, it is mainly divided into the common cold and the influenza. During a cold, in terms of diet, avoid foods that are too greasy, irritating, or spicy. Foods like eggs and milk are fine to eat. Drink more millet porridge and eat more vegetables and fruits such as celery, spinach, mung bean sprouts, tomatoes, carrots, and kiwi, which are rich in Vitamin C. These can help promote recovery of bodily functions and aid in alleviating symptoms of a cold. Also, drink plenty of water and get plenty of rest.
