IIN Food Sensitivities & Allergies 3

Question 1

Leaky gut (increased intestinal permeability) is believed to contribute to food sensitivities primarily by:

Accepted Answer

Allowing partially digested food proteins to enter the bloodstream and trigger immune responses

Answer

When tight junctions between intestinal epithelial cells loosen, larger food protein fragments can cross into systemic circulation and provoke immune activation.

Question 2

A client with a tree nut allergy is most at risk for cross-reactive reactions with which food group?

Accepted Answer

Other tree nuts

Answer

Many tree nuts share similar protein structures, so individuals allergic to one tree nut are at elevated risk of reacting to others.

Question 3

FODMAPs are a category of fermentable carbohydrates that can trigger symptoms in people with:

Accepted Answer

Irritable bowel syndrome (IBS)

Answer

FODMAPs are poorly absorbed short-chain carbohydrates that cause osmotic water draw and fermentation in the gut, commonly worsening IBS symptoms.

Question 4

Which laboratory test is considered the most clinically reliable for diagnosing a true food allergy?

Accepted Answer

Oral food challenge (OFC) conducted under medical supervision

Answer

The oral food challenge, where the suspected food is consumed under controlled medical observation, is the gold standard for confirming food allergy diagnosis.

Question 5

Histamine intolerance is best described as:

Accepted Answer

Impaired ability to break down dietary histamine, often due to low diamine oxidase (DAO) activity

Answer

DAO is the primary enzyme that degrades ingested histamine in the gut; deficiency allows histamine to accumulate and produce allergy-like symptoms.
