Intake of allergenic foods at 1.5 years and 3 years of age in a general child population in Japan: a cross-sectional study.

Caregivers avoided giving various foods, independent of allergy risk factors, to their young children. Since delayed introduction of an allergenic food has been reported to increase the risk of developing an allergy to the food, the results warrant future investigation of the development of food allergies in relation to current eating habits and recommendations.
