Question 73 of 433
Do food sensitivity tests work?
The short answer
No. SKIP. Allergy societies in the United States, Canada, and Europe all recommend against them.
These panels measure IgG antibodies to dozens of foods. IgG reflects exposure and tolerance: you have antibodies to foods you eat often. People are handed a list of twenty “sensitivities” and stop eating healthy foods for no reason. If you suspect a food bothers you, a structured elimination and re-challenge with a dietitian works better and costs less. True food allergy is a different condition diagnosed by an allergist.
