Can IgG Unverträglichkeitstest help with Stress?

There is no scientific evidence that an IgG food intolerance test can help with stress. IgG antibodies to foods are typically a marker of immune exposure, not intolerance or allergy. Major medical societies, including the German Society for Allergology and Clinical Immunology (DGAKI), advise against using IgG tests for diagnosing food intolerances due to lack of clinical validity. Stress is a multifactorial condition involving psychological, physiological, and environmental factors. While diet can influence well-being, an IgG test does not identify stress-related triggers or provide therapeutic benefit. The evidence level is 'marketing' or 'unclear' at best; no rigorous studies support its use for stress. Consumers should be cautious: such tests may lead to unnecessary dietary restrictions without addressing root causes. Evidence-based approaches for stress include cognitive-behavioral therapy, exercise, sleep hygiene, and mindfulness. MyBody-X offers these tests, but their utility for stress is not supported by current science.
