IIN Food Sensitivities & Allergies 2

Question 1

Which immune system component is primarily responsible for IgE-mediated food allergies?

Accepted Answer

Mast cells and basophils

Answer

IgE antibodies bind to mast cells and basophils, and upon re-exposure to the allergen these cells release histamine and other inflammatory mediators.

Question 2

A client reports bloating and diarrhea several hours after eating wheat but tests negative for celiac disease and wheat IgE. This most likely represents:

Accepted Answer

Non-celiac gluten sensitivity

Answer

Non-celiac gluten sensitivity produces GI and systemic symptoms from gluten without the autoimmune damage of celiac or IgE-mediated allergy.

Question 3

The 'Big 9' major food allergens recognized by the FDA include all of the following EXCEPT:

Accepted Answer

Corn

Answer

Corn is not one of the FDA's Big 9 allergens; the list includes milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, and sesame.

Question 4

Which symptom pattern is most characteristic of a true IgE-mediated food allergy rather than a food intolerance?

Accepted Answer

Rapid onset within minutes to 2 hours after exposure

Answer

IgE-mediated reactions are rapid because preformed IgE triggers immediate mast cell degranulation upon allergen contact.

Question 5

An IIN health coach working with a client who has a peanut allergy should recommend that the client carry which emergency medication?

Accepted Answer

Epinephrine auto-injector (EpiPen)

Answer

Epinephrine is the first-line treatment for anaphylaxis and must be administered promptly; antihistamines are too slow for life-threatening reactions.
