You can eat donkey meat in moderation when you have a cough, but do not eat too much. Donkey meat itself is a high-protein diet and is not well digested, and the digestive function decreases accordingly when you have a cough, so it is not suitable to eat too much of it. If you develop a cough, you should still pay attention to your diet and eat foods that are well digested and nutritious, such as lean vegetable porridge, tomato and egg noodles, egg custard, etc. You can also eat vegetables and fruits rich in vitamin C, such as apples, bananas, oranges, kiwis, dragon fruit, etc., and green vegetables, such as spinach, baby bok choy, rape and chard. Do not eat spicy, stimulating, greasy and cold food when you have a cough. Especially, you should not overeat, as this may cause indigestion. Of course, it is still important to emphasize rest and drinking more water when a cough appears, but older people should be careful not to drink too much water at once to avoid causing heart failure.
