Diet during influenza A should be kept light, while adequate and balanced nutrition should be ensured. Patients suffering from influenza A should pay attention to a light diet, drink plenty of water, avoid greasy, spicy and stimulating diets, and try to eat as little as possible of foods such as hot pot, fatty meats, fried chicken, barbecue, etc. As the digestive function of patients suffering from influenza A will be affected to a certain extent, patients should choose easy-to-digest foods, such as white congee, yoghurt, soya bean milk, fruit juice, etc., which can help to alleviate the burden on the stomach and intestines. During the period of illness, patients should also ensure adequate nutritional intake, including foods rich in high-quality protein and vitamins, such as meat, eggs, milk, fresh vegetables and fruits, which can replenish proteins and provide the body with a source of energy to promote the recovery of patients. Influenza A patients should go to the hospital in a timely manner for standardized treatment and dietary regimen under the guidance of the doctor.
