CLT Elimination Diets & Food Reintroduction 2 — Questions and Answers
Question 1: When introducing new foods during LEAP reintroduction, how many new foods should typically be introduced per challenge day?
- Five or more to accelerate dietary expansion
- Three foods simultaneously to save time
- One new food at a time to isolate reactions (Correct answer)
- Two foods from the same food family simultaneously
Correct answer: One new food at a time to isolate reactions
Introducing one food at a time is essential so that any adverse reaction can be attributed unambiguously to that specific food.
Question 2: What is the standard waiting period between introducing each new food during LEAP reintroduction?
- 12 hours
- 24 hours
- 48–72 hours (Correct answer)
- One full week
Correct answer: 48–72 hours
A 48–72 hour window allows delayed mediator-release reactions, which may not appear for up to 72 hours, to be fully observed before the next challenge.
Question 3: Which of the following responses following reintroduction of a food most strongly suggests a true sensitivity reaction?
- Mild hunger within one hour of eating
- Fatigue, bloating, headache, or return of the client's primary symptom within 48–72 hours (Correct answer)
- A temporary elevation in appetite lasting 30 minutes
- Improved energy and mood immediately after eating the food
Correct answer: Fatigue, bloating, headache, or return of the client's primary symptom within 48–72 hours
Recurrence of the client's characteristic symptoms—such as fatigue, GI upset, or headache—within 48–72 hours of challenge is the hallmark of a mediator-release sensitivity.
Question 4: If a client reacts to a food during reintroduction, what is the appropriate immediate action?
- Administer an antihistamine and continue the reintroduction schedule
- Remove the reactive food, wait until symptoms resolve, then continue reintroduction with the next safe food (Correct answer)
- Restart Phase 1 completely and extend it by one month
- Immediately introduce the next food to determine if the reaction was coincidental
Correct answer: Remove the reactive food, wait until symptoms resolve, then continue reintroduction with the next safe food
The reactive food is withdrawn and the client returns to confirmed safe foods until symptoms resolve, at which point reintroduction resumes with a different food.
Question 5: What is the purpose of a 'rotation diet' in the later stages of the LEAP protocol?
- To ensure the client eats every color of vegetable daily
- To prevent re-sensitization by avoiding eating the same food more frequently than once every four days (Correct answer)
- To rotate meal timing rather than food choices
- To alternate between high- and low-calorie days for metabolic variety
Correct answer: To prevent re-sensitization by avoiding eating the same food more frequently than once every four days
A 4-day rotation diet reduces repetitive immune exposure to any single food, lowering the risk of developing new sensitivities to previously tolerated foods.
Question 6: In LEAP reintroduction planning, which food category is generally introduced latest in the sequence?
- Fruits that tested in the lowest-reactivity MRT band
- Foods that tested as moderately or highly reactive on the MRT (yellow/red bands) (Correct answer)
- Lean proteins with no MRT reactivity
- Non-starchy vegetables from the green MRT band
Correct answer: Foods that tested as moderately or highly reactive on the MRT (yellow/red bands)
Foods with higher MRT reactivity scores are reserved for the final reintroduction phases, after the client has achieved stable tolerance to their safe foods.
Question 7: How does cross-reactivity between foods affect LEAP reintroduction planning?
- Cross-reactive foods must always be introduced simultaneously to confirm reactivity
- It is irrelevant because MRT measures individual foods, not food families
- Foods from the same botanical or chemical family may need to be spaced apart, as a reaction to one may predict reactions to related foods (Correct answer)
- Cross-reactive foods are automatically excluded from all LEAP diets permanently
Correct answer: Foods from the same botanical or chemical family may need to be spaced apart, as a reaction to one may predict reactions to related foods
Shared proteins among food families (e.g., shrimp and crab) can cause cross-reactive mediator release, so a CLT should space related foods in the reintroduction schedule and monitor carefully.
