You can eat eggs in moderation when you have a cold and cough. When you are sick, your gastrointestinal function is poor, so you should avoid eating foods that are not well digested. Eggs and seafood are difficult to digest and eating such foods when you are sick is likely to make your condition worse. Protein can be replenished by eating other milder foods such as milk, soy products, etc. During cold, whether it is wind-cold or wind-heat cold, avoid eating all nourishing, greasy, sour and astringent foods, such as pork, duck, chicken, mutton, glutinous rice, maitake, ginseng, placenta, gum, crab, pomegranate, etc., and all kinds of sticky dessert foods. In case of wind-cold cold, you should also avoid cold foods, such as persimmon, tofu, snail, mussels, raw radish, raw lotus root, raw groundnut, herbal tea, honeysuckle and fat sea. People with wind-heat cold should also avoid eating ginger, pepper, cinnamon, cloves, white wine, cordyceps, etc.
