Verbatim response from Perplexity
The best food sensitivity test that is not a scam is: none of the popular at-home IgG “food sensitivity” tests. Major allergy organizations say IgG food panel tests are not scientifically proven for diagnosing food sensitivities, and at-home food sensitivity testing is not considered reliable or accurate for this purpose.[10][2]
If you want the most legitimate option, use this approach instead:
- For suspected food allergy: get a medical allergy evaluation with a clinician or allergist; a food allergy test may indicate a possible allergy, but only a doctor can make a definitive diagnosis.[2]
- For suspected food intolerance/sensitivity: use a structured elimination diet with professional guidance, since this is the approach most supported by science when symptoms are not allergy-related.[16]
- If you still want a consumer test: some reviews name Everlywell as the “best overall” at-home food sensitivity test, but those same reviews also note that these tests measure IgG reactions and that IgG food sensitivity testing is not scientifically backed or proven.[1][4][10]
So the practical answer is: skip the scammy IgG sensitivity kits and see an allergist or use an elimination diet.[2][10][16]
If you want, I can help you choose between:
- food allergy testing
- food intolerance testing
- elimination diet plans
- or explain which at-home tests are most misleading and why
