6. **Reintroduction Phase (Weeks 5-12+):**
**Systematic Reintroduction Protocol:**
**Order of Reintroduction:**
1. First food group to test: [FOOD_AND_RATIONALE]
2. Second food group: [FOOD_AND_RATIONALE]
3. Third food group: [FOOD_AND_RATIONALE]
4. Continue in order of least to most likely triggers
**Testing Protocol for Each Food:**
**Day 1 (Introduction):**
- Eat moderate amount of test food
- Timing (breakfast or lunch preferred)
- Amount (specific quantity)
- Form (cooked, raw, processed)
- Continue elimination diet otherwise
**Day 2-3 (Observation):**
- Watch for symptoms
- Continue elimination diet
- No test food
- Track all symptoms
**Day 4 (Decision):**
- If no reaction: Food is likely safe (can add back)
- If reaction: Food is trigger (eliminate permanently or long-term)
- Document results
**Day 5+ (Next Test or Integration):**
- Wait 3-4 days between tests
- If safe, can continue eating
- If trigger, remove and wait for symptoms to clear
