Sensitivity vs. Allergy

Food Sensitivities Testing is not as same as a typical Food Allergy Test (scratch test) that you might have done at your allergist’s office.  The major difference between Food Allergy and Food Sensitivities is the onset of symptoms. A food sensitivity test is a blood test that examines your immune system’s response to a wide variety of foods and chemicals.

The Difference between Food Allergy and Food Sensitivities

Food Allergy is much more easily diagnosed because its onset is faster, from immediate to 1 hour after ingestion. Sensitivity vs. AllergyWith Food Sensitivities, delayed reactions manifest in many different ways, can affect any organ system in the body, and can take anywhere from 45 minutes to 72 hours to become apparent. That means you may have a symptom, like a migraine headache, on Tuesday afternoon, caused by the meal you ate at Sunday brunch. This “delayed response” is why food sensitivities are often misdiagnosed, or go completely undiagnosed.

The immunologic mechanism in Food Allergy is IgE, but in Food Sensitivity there are multiple mechanisms: white blood cells, IgG, IgM, C3 and C4. Body organs affected with Food Allergies are limited to airways, skin, gastrointestinal tract and are often acute, whereas in Food Sensitivities, any organs system in the body can be affected and are often chronic (though sometimes acute with a histamine response. The treatments prescribed (for undiagnosed food sensitivities) usually provide only temporary relief that mask the symptoms instead of addressing the root cause of the problem. I was one of them.
