The Cure (For Peanut Allergy)?

There is an interesting study from King's College, London demonstrating pretty conclusively that exposing children in early life to peanut butter and other peanut-containing foods, greatly reduces the probability of that individual developing peanut allergy in later life (http://www.theguardian.com/society/2015/feb/23/feed-babies-peanuts-reverse-allergy-rise). Peanut allergies (including full-blown anaphylactic shock, a condition that is life-threatening) have been on the rise in recent years and this may be a consequence of parents avoiding anything peanut related in their child's food. Obviously, whole peanuts should not be given to young children as they are a choking hazard but peanut butter (if administered carefully) would seem to be safe enough. The finding is entirely consistent with the view that children develop tolerances for certain foods in early life or even within the womb (this may account to cultural differences in the rates of certain food allergies).
