Is MY FOODBOOK useful for allergy?

Whether MY FOODBOOK is useful for allergies cannot be directly answered from the provided context, as the product is not mentioned. In general, consumer tests for food allergies or intolerances (e.g., IgG-based or genetic panels) are not recommended by allergy guidelines (EAACI, AAAAI). They often yield false positives and cannot distinguish between sensitization and clinical allergy. For example, a high peanut IgE level indicates sensitization, not necessarily allergy. True diagnosis requires a detailed history and specialist evaluation. MY FOODBOOK may provide some insights into potential triggers, but its clinical utility is limited. Evidence-based allergy testing relies on specific IgE, skin prick tests, and oral food challenges. Therefore, while MY FOODBOOK might be marketed for allergy, its usefulness is questionable and should not replace medical advice. Evidence level: practice/mixed.
