I'm not buying this pseudo-scientific nonsense. Allergies have to do with the immune system, but you cannot be "immunized" against an allergy. Someone genetically predisposed to a peanut allergy cannot have that problem thwarted by early exposure. Allergies grow worse with exposure, as the substance which triggers the allergy is memorized by the immune system. This is sensitization. The second problem with the claim is that nobody actually does what the article describes: avoid giving kids peanut butter until they are 3. The modern protocol is that peanut butter is cautiously introduced in a tiny amount to a weaning infant. If that looks okay, they get more until it either looks obvious that they are fine, or else that they are not. The third problem is that even if people doggedly followed this three year rule, it has not been enough time for that to be imprinted on the human genome, so that we have more prevalence of peanut allergy now in our DNA. All we have today is better awareness. That's why there is more of everything, not just peanut allergies. I wonder, do the believers in this hypothesis also think this would work for industrial irritants? If we just expose infants to epoxy resins, they will later able to work in a fiberglass shop without any problems?
