If a child’s fever is not caused by a digestive tract infection and is not allergic to milk and its products, yogurt can be consumed appropriately. If a child’s fever is caused by a gastrointestinal infection, it may be accompanied by diarrhea, abdominal pain and other symptoms, and at this time it is not recommended that the child consume yogurt, because yogurt has a high content of protein, and if the child’s digestive function is poor when consuming too much yogurt will exacerbate the condition. Most of the proteins in yogurt are hydrolyzed during the fermentation process into amino acids and peptides that are more easily absorbed and less allergic, so babies who are allergic to cow’s milk may not be allergic to yogurt. If the baby does not have a history of allergy to milk and its products, it can consume yogurt appropriately to replenish nutrients and strengthen resistance. However, if the baby has a history of allergy to milk and its products, it is still recommended not to consume yogurt during fever, so as to avoid triggering allergic symptoms and affecting the treatment of the original disease.
