What are Allergies?

FAQ Allergies address your questions on Allergies, which are a growing health concern. Almost one-third of the industrialized world suffers from Allergies, while one-fifth of North Americans are affected by Hay fever alone. Asthma is diagnosed in one-tenth of North Americans, while Food Allergies have been self-reported by 2.5 million Canadians & 15 million Americans.

Allergies are an overreaction to a normal immune response.  Your immunity is a powerful, intricate system that protects you by combating those causing sickness or infection, such as bacteria & viruses, while also repairing cancer cells.

When other substances enter your body, whether the environment or food, a hyperactive immunity will cause an allergic reaction. People with Allergies have hyperactive immune systems that produce exaggerated responses to something a healthy person would not react to.  It is important to understand that having Allergies means your immunity is not healthy.

What is an Allergen?

An allergen is anything that can trigger an aggressive immune response, wherein the body thinks it’s fighting an offender, that is usually harmless. Allergens may be introduced by eating, breathing or touching.
