Looking at allergies vs. intolerances

Have a food allergy? Many allergies -- to things like wheat, peanuts and milk -- are often not allergies at all, but just simple intolerances. Sound the same, don't they?

In wheat, the "gluten" part may be the cause of an allergic reaction instead of the wheat itself (but since gluten is part of the wheat stalk, wheat is often banned from many pantries).

Defining an intolerance is as easy as saying that there is no immune system response from the body. In an allergy, the immune system's response is what causes those rashes and dry heaves. Want to know more? See this.
