The wrong advice may have caused a steep rise in kids' allergies

Let them go nuts and eat nuts. Let them crawl in the sand, and don't fret if they get soiled by dog poo. Babies and toddlers need to be exposed to "trigger" foods like peanuts and random pickings from the great outdoors to avoid developing allergies later in life. The steep rise in allergies in South Africa and globally seems to be linked to decades of the wrong advice - that young children should be protected from contact with potential allergens.
