[Solid food introduction and allergic risk]

Solid food introduction in childhood suffered in recent decades many changes due to findings of increased allergies with a likely mismatch schemes and a recent reversal of recommendations for delaying the introduction of foods. The advice may still change due to the latest findings on the mechanisms of sensitization. There is little or no certainty on the date and to provide food at the right time. It seems that the introduction of solid foods may be favorable age between 4 and 6 months. Delaying the introduction of allergenic potential has not yet demonstrated a preventive effect. It could be preferable to induce an early oral tolerance that cause allergy with transcutaneous sensitization by ingesting any new dietary protein introduced in the environment of the infant.
