IgE vs. IgG: different antibodies, different meaning
IgE (immunoglobulin E) drives true food allergies — the rapid reactions involving hives, swelling, vomiting, or anaphylaxis. IgE blood tests, alongside skin-prick testing and food challenges, are established tools allergists use.
IgG (immunoglobulin G) is what most “food sensitivity” kits measure. Here is the problem: IgG to foods largely reflects exposure, not intolerance — people commonly have IgG to foods they eat often and tolerate perfectly. Major allergy societies have stated IgG testing should not be used to diagnose food sensitivity.
What IgG results actually show
An IgG panel typically flags dozens of foods as “reactive,” which alarms buyers into restrictive diets. But the flagged foods are often just the ones you eat most. Restricting them without guidance risks nutritional gaps while the real issue — IBS, lactose intolerance, celiac, stress-related gut symptoms — goes unaddressed.
When testing is appropriate
See an allergist promptly if you have ever had rapid-onset hives, lip or tongue swelling, throat tightness, or vomiting after eating — those are allergy red flags. For chronic bloating or digestive discomfort without allergic signs, a gastroenterologist workup (including celiac screening, which is a validated blood test) comes before any sensitivity kit.
The elimination-diet alternative
For suspected non-allergic food issues, the evidence-backed approach is a clinician-supervised elimination and reintroduction diet: remove suspects for a few weeks, reintroduce one at a time, and watch symptoms. It is slower than a mail-in kit and far more informative.
Celiac disease needs specific antibody tests (tTG-IgA) while still eating gluten, followed by biopsy. IgG food panels do not test for celiac, and going gluten-free before proper testing makes real diagnosis harder.
Common questions
Are food sensitivity tests a scam?
Not exactly — they measure real IgG antibodies. The issue is interpretation: the results do not mean what the marketing implies. Skepticism is warranted.
What is the difference between intolerance and allergy?
Allergy is immune-mediated and can be dangerous within minutes. Intolerance (like lactose intolerance) is usually digestive, dose-dependent, and uncomfortable rather than dangerous. Different mechanisms, different tests.
Can a sensitivity test find my IBS trigger?
Unlikely to do so reliably. IBS triggers are better found through structured elimination diets with a dietitian than through IgG panels.
Should children be tested with these kits?
No — restrictive diets in children risk growth and nutrition problems. Any childhood food concern belongs with a pediatric allergist.
