Lung infections generally do not have food contraindications in the absence of allergies. Lung infections are usually caused by pathogenic microorganisms such as Streptococcus pneumoniae, Staphylococcus aureus, Mycoplasma pneumoniae, fungi, influenza virus and other infections of the lungs, which can be manifested as fever, cough, sputum, chest pain and so on. As for patients with lung infections, there are no food contraindications in the absence of allergies. On the contrary, common foods such as beef, eggs and other protein-rich foods can provide the body with high-quality protein, fat and other nutrients, which are helpful for the body’s recovery. If there is a lung infection, it is recommended to go to the hospital as soon as possible, and follow the doctor’s instructions to standardize the treatment, so as not to delay the condition.
