You can eat eggs when you have a cough. Cough is mainly considered to be caused by respiratory and cardiovascular diseases, and when you have these diseases you need to pay attention to your diet and strengthen your nutrition. Eggs contain more protein and other vitamins and trace elements, which are good for your health. You can eat them in moderation, usually 1-2 per day, to replenish the nutrients your body needs. During a cough, you should pay attention to a light diet and try not to eat scrambled eggs. If they are greasy, they will aggravate the cough, but you can make egg custard or boiled eggs.
