In a study of 450 infants and children, babies who ate a blend of common allergens everyday had higher protective IgG4 antibodies and lower food-specific IgE antibodies, compared to babies who ate only one or two allergens.
In 2021, the North American Allergy Societies (AAAAI, ACAAI, and CSACI*) released a consensus document based on recently published data indicating, "the strong potential of strategies to prevent the development of food allergy."
Researchers in Australia have found encouraging data to suggest that recently introduced infant feeding guidelines that include recommendations for early allergen introduction may be slowing the rate of food allergy anaphylaxis hospital admissions.
