You can eat peanuts during fever, but try not to eat too much to avoid increasing the burden on the digestive system. Fever is a common clinical symptom, while most patients have fever related to infections, such as bacterial, viral, pathogenic microorganisms, and pathogen infections, which may cause an increase in body temperature. Eating peanuts appropriately during fever usually does not affect the health of the body and does not lead to an increase in body temperature. Therefore, patients can eat peanuts. However, be sure to pay attention to the intake and try not to eat too much. If the fever is caused by a cold, the digestive function is weak during the disease, eating too many peanuts may increase the burden on the gastrointestinal tract, and some patients may show signs of indigestion. During the fever period, you should pay close attention to the change of body temperature in the armpit, and if necessary, go to the general internal medicine department of the hospital to look for the cause of the fever and give treatment for the cause.
