Immunotherapy and peanut allergies
Immunotherapy — controlled, careful exposure to an allergen — has been shown to reduce the severity of allergic reactions. Sometimes, it can all-but-eliminate the allergy altogether. Increasingly, researchers are finding this is true for dangerous peanut allergies
, as well as the pollen allergies immunotherapy has been more commonly used to fight. Along the same lines, a growing body of evidence suggests that keeping fetuses, infants, and small children away from possible allergens actually increases — not decreases — their likelihood of developing an allergy to those foods.
