In The Peanut Allergy Epidemic: What’s Causing It and How to Stop It (Skyhorse Publishing, 2015), Heather Fraser explains the phenomenon of a life-threatening allergy in children, in specific countries, occurred simultaneously, without warning and quickly intensified. The number of allergic children in the United States alone went from virtually none to about two million in just twenty years. As these children have aged, the combined number of American adults and children allergic to peanuts has grown to a total of four million.

One study confirmed that most Venezuelan Indians living in the rainforest had worms but no allergies while very few of the wealthy Venezuelans living in the cities had worm infections, but many had allergies.












This is a provocative concept. However, because it was developed before the rise in peanut allergy, it lacks specificity — again, why peanut and why the sudden increased prevalence in children?
