Peanut allergies affect an estimated three million people in the U.S., and while there is currently no known cure or treatment, new research suggests that introducing peanut-containing foods during infancy may help prevent the development of a peanut allergy. As of January 2017, an expert panel sponsored by the National Institute of Allergy and Infectious Diseases (NIAID) issued this new recommendation for peanut-containing foods. While these new guidelines may help reduce the incidence of children developing peanut allergies, a 2015 study suggests that genes and epigenetics also play a role.
