“More than one in 15 Canadian children, or two kids in every classroom across the country, report having at least one food allergy.” Most allergies, it appears, are caused by very few foods: peanuts, milk, eggs, tree nuts, fish, shellfish, soy, wheat and sesame. Allergies to these foods have been on the rise since the 1990’s and can be life threatening.

When a person has an allergy and comes in contact with a peanut, for example, their immune system overreacts to the allergen by producing antibodies called IgE’s (Immunoglobulin E).

These antibodies travel to cells that release chemicals, causing an allergic reaction. IgE-mediated food reactions can cause severe allergy anaphylaxis that if left untreated can be life-threatening. EpiPens and antihistamines help in the control of many food allergy episodes.

Dr. Upton touched on the complex issues surrounding allergies such as the inaccuracy of testing procedures, the elimination of parasites in much of the developed world, living in cities instead of farms, and the timing of the introduction of solid foods to infants as all influencing the rate of allergic disease.

We are fortunate to have doctors such as Dr. Upton who have the passion and expertise to help unscramble this complex world of allergies. For more information visit .
