What role does MY FOODBOOK play in allergy?

MY FOODBOOK is a consumer test by MyBody-X that claims to identify food allergies or intolerances. However, such tests often rely on IgG antibodies, which are not validated markers for true IgE-mediated allergies or clinical intolerances. The scientific evidence is weak: studies indicate IgG-based tests produce many false positives and may encourage unnecessary dietary restrictions. Real food allergies should be diagnosed by a specialist using established methods (skin prick test, IgE blood test, oral food challenge). MY FOODBOOK cannot diagnose or manage allergies. It is best considered a lifestyle product with limited utility. Caution: self-interpretation may lead to nutritional deficiencies or delayed proper treatment. The evidence level is marketing-driven, not clinically robust.
