Myths vs facts: MY FOODBOOK and gut health

Myth: MY FOODBOOK can pinpoint exactly which foods cause bloating via an IgG blood test. Fact: IgG antibodies are not a validated marker for food intolerances. These tests often yield false positives and are not diagnostic; the evidence is marketing-based, not clinical. A microbiome test can reveal bacterial levels (e.g., Bifidobacteria, Lactobacilli) but cannot diagnose the cause of bloating – many factors like diet, stress, and medical conditions play a role. DNA tests for metabolism have small effect sizes and are not prescriptive. MY FOODBOOK may serve as lifestyle inspiration, but it is not a substitute for medical evaluation. Persistent symptoms require a doctor’s assessment.
