The Difference Between Food Allergies, Intolerance, & Sensitivities


Confused by the different terminology associated with food triggers? 

You’re not alone. And what the heck is a food trigger anyway?

*A food trigger simply refers to a food that causes a negative reaction in an individual. 

Now that we've got that out of the way, here's a quick run down of the different types of reactions and the ways in which they're diagnosed.

Food Allergy:

Food allergies cause immune system reactions that typically occur within a few minutes to two hours. Symptoms range from mild to severe and include hives, dizziness, trouble breathing, swollen tongue, and anaphylaxis (which can be life-threatening). Food allergies can only be (and should only be) diagnosed and treated under the care of a physician.


Celiac is an autoimmune disorder where ingestion of gluten leads to damage of the small intestine, which can lead to serious health problems. Diagnostic testing for celiac is done only through your physician. (If you suspect you may have celiac, talk to your doctor and get tested prior to cutting gluten out of your diet. This will give you the most accurate results).

Food Intolerance:

Food intolerance can be caused from a lack of enzymes needed for proper digestion (lactose or gluten) which can be diagnosed through your doctor with medical testing.

Food sensitivity:

Food sensitivity is a general term for unpleasant or negative reactions to foods. Food sensitivities can cause much of the same symptoms as food allergies, but they do not cause an immune system reaction or pose any threat of anaphylaxis. Currently there are no medical tests to determine food sensitivities and an elimination diet is the best way to uncover them.

Depending on which study you read, it's predicted that anywhere between 40% and 90% of the population has food sensitivities. Crazy, right? (Personally, I think it has everything to do with our food supply, but we can debate that in another post!).
