Early exposure to food and food allergy in children

Can Fam Physician. 2014 Apr;60(4):338-9.


Question I have been under the impression that infants should avoid potential allergenic foods such as nuts, cow's milk, and eggs in order to avoid developing allergic reactions. What advice should I give parents regarding the introduction of food in infancy and the development of food allergy? Answer There is no evidence that delaying the introduction of any specific food beyond 6 months of age helps to prevent allergy. A recent Canadian Paediatric Society statement recommends no delay in the introduction of food in infancy. Recent research also appears to suggest that early introduction of potentially allergenic foods (at 4 to 6 months of age) might actually provide a form of protection and help prevent allergy, but more research is needed.
