From a modern medical perspective, patients with a cold can totally eat eggs. Eating eggs will not affect the cold and is actually beneficial. A cold is a type of infectious disease, specifically, a common acute upper respiratory tract infection that can cause the body to consume resources, including water and nutrients such as proteins. Eggs are a high-quality source of protein and are very rich in nutrients. Therefore, eating eggs does not worsen the symptoms of a cold. In fact, the nutrients in eggs are a very beneficial supplement to counteract the depletion caused by the illness. Therefore, if cold patients have a good appetite, they can eat eggs and are encouraged to eat more eggs.
