Lay opinion vs evidence: Gluten Männer

Lay opinion often claims gluten affects men more severely—causing 'gluten belly', low libido, or digestive issues—but scientific evidence is limited. Celiac disease is underdiagnosed in men, likely due to lower healthcare-seeking behavior, not biological protection. When diagnosed, men present with similar symptoms but also atypical ones like osteoporosis or fatigue. Non-celiac gluten sensitivity (NCGS) prevalence appears similar across sexes, but studies rely on self-reports and small samples, with high placebo responses. Some men report symptom relief on a gluten-free diet, but rigorous trials show no consistent gender difference. DNA tests (e.g., HLA-DQ) can rule out celiac but not diagnose it; MyBody-X offers such tests with clear caveats. Overall, evidence for gender-specific gluten effects is weak. For persistent symptoms, medical evaluation (celiac serology, endoscopy if indicated) is essential before adopting restrictive diets. Marketing claims about 'male gluten sensitivity' are not evidence-based.
