Reviews of food allergens in general stated that introducing solid foods to infants at ages 4–6 months may result in the lowest subsequent allergy risks for eczema, allergic rhinitis and more severe reactions, with the best evidence for peanuts and chicken eggs. As of March 2022, one clinical trial attempted to determine whether introducing sesame to the diets of infants early or delaying until older would affect the risk of subsequent allergy, but there were too few confirmed subsequent sesame allergy subjects in the test or control groups to conduct a statistical analysis.
