Food Allergies

With allergies, the immune system reacts by releasing cells called antibodies.  Foods that cause antibodies to be released are called allergens.  There are two types of antibodies commonly produced in response to foods.

IgE Allergies

These are what most people think of when they think allergies.  IgE reactions are more immediate and occur within minutes of consumption.  These allergies can be life-threatening and one of the most common is an IgE allergy to peanuts.
IgG Allergies

This type of reaction can take hours or days to create an inflammatory response.  IgG allergies are insidious allergies that are tough to identify but can cause disruption in a number of different organ systems including the digestive tract, lungs and skin.  Conditions associated with IgG food reactions include eczema, astham, environmental allergies, tantrums and headaches.  IgG allergies also pull resources away from the immune system and can lead to frequent ear infections, colds and upper respiratory infections.
