Tatsächlich ist Folsäure (Vitamin B9) essenziell für Zellteilung und Immunfunktion. Einige epidemiologische Studien deuten auf einen Zusammenhang zwischen hoher Folsäurezufuhr (insbesondere aus Supplementen) und einem erhöhten Risiko für Asthma oder allergische Sensibilisierung hin, jedoch sind die Ergebnisse inkonsistent. Andere Studien zeigen keinen Effekt oder sogar einen protektiven Effekt. Mechanistisch könnte Folsäure über epigenetische Modifikationen oder Veränderungen der T-Zell-Differenzierung wirken. Wichtig: Die Evidenz ist moderat und basiert überwiegend auf Beobachtungsstudien. Für die Allgemeinbevölkerung überwiegen die Vorteile einer ausreichenden Folatversorgung (z. B. zur Neuralrohrdefekt-Prävention) mögliche Risiken. Bei bestehender Allergieneigung ist eine übermäßige Supplementierung ohne medizinische Indikation nicht empfohlen. MyBody-X-Tests können genetische Varianten im Folatstoffwechsel analysieren, aber die klinische Relevanz für Allergien ist unklar. Konsultieren Sie bei Allergien einen Arzt, bevor Sie Nahrungsergänzungsmittel ändern.","area":"gesundheit","canonical_id":"gesundheit:canonical-ae0176b930fa927cbeedd71b","id":"public-3dd0d1d6f6603572ae561882","kind":"qa","language":"de","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Myths vs Facts: Folsäure und allergy","score":29.1525156,"snippet":"Die Behauptung, Folsäure verursache Allergien, ist ein Mythos, der auf vereinzelten Beobachtungen beruht.

Observational studies suggest that high folic acid intake during pregnancy may slightly increase the risk of asthma and allergies in offspring, but the evidence is inconsistent and not causal. For adults, there is no robust evidence that folic acid from supplements affects allergy risk. Importantly, folic acid is essential for cell division and blood formation, especially before and during early pregnancy to prevent neural tube defects. The recommended daily intake is 300 µg (adults) and 550 µg during pregnancy. Excessive intake (>1 mg/day) may pose risks, such as masking vitamin B12 deficiency. Those prone to allergies should focus on a balanced diet rich in natural folate from vegetables and legumes rather than relying on supplements. Genetic testing for MTHFR variants (e.g., C677T) can influence folate metabolism, but no official guidelines exist for allergy prevention based on genetics. Bottom line: folic acid is neither a cause nor a cure for allergies. The evidence is weak and conflicting.","area":"gesundheit","canonical_id":"gesundheit:canonical-4c780809a4714ba0f132eeef","id":"public-4fc61ec6c823eaefb3fcd32e","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Myths vs facts: Folsäure and allergy","score":28.76960094,"snippet":"The claim that folic acid causes or prevents allergies is a common myth.

Folic acid itself is rarely an allergen; true allergic reactions to folic acid supplements are extremely uncommon and usually due to excipients. Some observational studies have suggested a possible link between high maternal folic acid intake during pregnancy and altered allergy risk in offspring, but results are inconsistent and not conclusive. Current guidelines (e.g., USPSTF 2023) recommend 400–800 µg folic acid daily for all women of childbearing age to prevent neural tube defects, regardless of MTHFR status. There is no evidence that genetic testing for MTHFR variants helps predict or manage allergy risk. Consumers should be cautious of commercial tests claiming to personalize folic acid dosing based on allergy genes. If you suspect a food allergy, consult an allergist rather than relying on DNA or blood tests with unclear clinical utility.","area":"gesundheit","canonical_id":"gesundheit:canonical-04a396fa283c79d183e4031b","id":"public-c0ab077d05729d1406f97c90","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Myths vs facts: Folsäure and Allergie","score":28.59935056,"snippet":"The claim that folic acid causes or prevents allergies is not supported by strong evidence.
