When “healthy foods” don’t feel healthy
What “food sensitivity” can mean (and what it doesn’t)
A grounded approach to testing: helpful, optional, and not one-size-fits-all
Testing can be one data point. The most valuable “test” is often a clear, repeatable pattern: what changed, how quickly, and what happened when the food was reintroduced in a controlled way.
Step-by-step: a realistic elimination-and-reintroduction plan
1) Pick a clear “why” and a short timeline
2) Start with the least restrictive change that matches your symptoms
3) Track like a scientist (not like a critic)
4) Reintroduce in a structured, repeatable way
5) Build your “personal tolerance map”
Quick comparison table: common approaches
| Approach | Best fit for | Pros | Watch-outs |
|---|---|---|---|
| Basic elimination + reintroduction (few suspected foods) | Clear suspects (ex: dairy, gluten, eggs) and consistent symptoms | Simple, targeted, less restrictive | Can miss “dose-related” triggers without structured portions |
| Low FODMAP (short-term) + reintroduction | IBS-style bloating/gas, frequent gut discomfort | Well-described 3-step process: restrict, reintroduce, personalize | Too restrictive if done long-term; reintroduction is essential |
| IgG “food sensitivity” panels | Curiosity/data-seekers (as one data point only) | May help generate hypotheses to test with diet | Interpretation is controversial; not the same as allergy testing |
Did you know? (Fast facts that can reduce confusion)
Sometimes the “trigger” is the dose, not the food—especially with certain carbohydrates and sugar alcohols.
For FODMAP-style work, published guidance emphasizes reintroduction and personalization—restriction alone isn’t the endpoint. (research.monash.edu)
The right next step depends on the type of reaction and timing of symptoms. (mayoclinic.org)
