An elimination diet is a gold-standard diagnostic method for identifying foods that trigger symptoms. When applied properly, it can provide major improvements in IBS, food intolerance, eczema, and migraine.
How Is an Elimination Diet Applied?
Phase 1 — Elimination (2–6 weeks): Suspected foods are completely removed from the diet. This list commonly includes gluten, dairy, egg, soy, corn, peanut, alcohol, and processed foods. Symptoms are tracked during this period.
Phase 2 — Reintroduction: Each food group is reintroduced one at a time with 3-day intervals. Whether symptoms are triggered, when they start, severity, and resolution are recorded. This phase takes at least 4–6 weeks.
Key Considerations in Elimination Diets
- Do not apply without dietitian supervision
- Avoid inadequate calorie intake during elimination
- Be patient during reintroduction; do not rush
- Keep a symptom diary to guide decisions
- In children, growth monitoring is essential
Who Can Benefit?
Individuals with IBS, chronic headache or migraine, eczema or psoriasis, chronic fatigue, bloating and gas, or unexplained digestive symptoms may benefit from this protocol.
