Dietotherapy is the basis for treating food allergies. Breastfeeding with a mother's hypoallergenic diet is optimal for children with food allergies. In the absence of milk from the mother and with allergies to cow's milk, soya mixtures (Alsoy, Bonasoa, Frisoosa, etc.) are used. If soy is intolerant, a mixture based on products of high protein hydrolysis (Alfare, Alimentum, Pepti-Junior, etc.) and partial hydrolysis milk protein (Humana, Frisepep).
