Embrace Exposure to Build Immunity

Immune tolerance develops through early exposure to allergens, countering past recommendations of avoidance. Contrary to the belief that avoiding peanuts prevents allergies, introducing peanuts and other common allergens early in infancy helps children tolerate these substances later in life. This shift in understanding reflects a broader principle that embraces exposure, linking hygiene and microbiome factors to the rise of allergies. The initial guidance by health authorities stemmed from perceived trends in peanut allergies, but this approach has evolved, demonstrating the need for adaptive practices in managing childhood allergies.
