Early Peanut Introduction Reduces Allergy Risk in Infants

Early Introduction of Peanuts to Prevent Allergies

Experts now recommend introducing peanuts to infants between 4 and 6 months of age to reduce the risk of developing peanut allergies. This guidance stems from studies showing that early peanut introduction can lower the likelihood of allergy by approximately 43 to 80 percent, especially in high-risk infants such as those with severe eczema or egg allergy. Introducing peanut-containing foods during this window supports immune tolerance development, which may help prevent allergic reactions later in life.

Assessing Infant Risk and Safe Practices

Before introducing peanuts, families should discuss their baby’s allergy risk with a pediatrician. High-risk infants may require allergy testing or evaluation by an allergist to ensure safety. For moderate- or low-risk infants, parents can begin peanut introduction at home once solid foods are tolerated. Continuing to include peanut products regularly in the diet after initial introduction is advised to maintain protection against allergy development.

Long-Term Benefits and Recommendations

Research confirms that early peanut introduction provides lasting allergy prevention benefits extending into childhood and adolescence. Health authorities encourage parents to start peanut exposure early and consistently, integrating it thoughtfully alongside breastfeeding and other complementary foods to promote overall immune health.
