Influenza, also known as the flu, occurs when humans lose resistance to the influenza virus and then get infected in the upper respiratory tract, manifesting mainly with symptoms such as sore throat, cough, and fever. Of course, the influenza virus can also cause nausea, vomiting, and even abdominal pain and diarrhea.

Therefore, diet is very important during the flu season or for those who are infected with the flu. It is recommended that individuals with the flu, or those who have contracted it, should consume foods rich in vitamins, carbohydrates, and proteins, such as fresh vegetables, fruits, fish, beans, lean meats, and fish, to boost resistance and promote the recovery of digestive functions.
