Allergies have increased in the population 10 fold in 10 years. I’ve just written a report on allergies which should be available on my website in the next few days. It will be a free report, so watch out for it.
Peanut allergies in children more than tripled from 1997 to 2008 according to a Mount Sinai School of Medicine phone survey in the Journal of Allergy and Clinical Immunology.
In 2008, 1.4 per cent of children in the survey were reported to have peanut allergies, as opposed to just 0.4 per cent in 1997.
Researchers estimate more than three million Americans report peanut and/or tree nut allergies.
Several theories exist for the spike in food allergies. The main theory is the “hygiene hypothesis” that suggesting that “clean living” with less farm living and overuse of medications to prevent and treat infections leaves immune system more prone to attack harmless proteins like those in foods, pollens and animal dander.
