SALEMI, Claudia. Optimal window of food introduction and prevention of food allergies in high-risk infants. An Venez Nutr [online]. 2020, vol.33, n.1, pp.51-60.  Epub 02-Abr-2021. ISSN 0798-0752.

In recent decades, the early introduction of foods in infants' diet has been described as a risk factor for developing specific pathologies, among which food allergies stand out. Due to the increasing prevalence of food allergies, both in developing and developed countries, it is necessary to identify the optimal time to introduce foods to prevent allergies in high-risk infants. The most recent evidence has shown that the strategies proposed to delay exposure to allergenic foods have not reduced the risk of developing allergies. Therefore, a paradigm shift has led to the publication of new guidelines that recommend not delaying the introduction of solid foods after 4-6 months of age, both in low-risk and high-risk infants, to prevent food allergy. In this review, we describe the current scientific evidence on the relationship between the timing of the introduction of allergenic foods (peanuts, eggs, milk, cereals, and fish) into infants' diet and the development of food allergies.
