Lay opinion vs evidence: IgE Allergie Alltag

In everyday life, many lay opinions circulate about IgE-mediated allergies: that they can be 'cured' by detox diets, that supplements like vitamin C or quercetin lower IgE production, or that a DNA test can pinpoint allergens. The evidence tells a different story. IgE allergies are driven by specific IgE antibodies against harmless environmental triggers. Diagnosis relies on skin prick tests or laboratory measurement of specific IgE (sIgE) – not on consumer genetic tests. MyBody-X and similar tests lack clinical validation for allergy diagnosis. Management is based on allergen avoidance, symptomatic medication (antihistamines, corticosteroids), and allergen immunotherapy (desensitization). Supplements have not shown consistent benefit in randomized trials for reducing IgE levels or symptoms. The evidence for such 'everyday remedies' is mostly mechanistic or anecdotal, not from robust human studies. Caution: self-treatment can delay proper care and increase anaphylaxis risk. Bottom line: evidence-based allergology differs sharply from marketing claims.
