What to watch with Zöliakie Test and Langlebigkeit?

Combining a celiac test with longevity is scientifically challenging. A celiac DNA test (typically HLA-DQ2/DQ8) indicates genetic predisposition, not disease. Only about 2–5% of carriers develop active celiac disease. Longevity tests from direct-to-consumer companies are often speculative, relying on small GWAS effects (e.g., FADS2, PPARG) that have limited individual predictive value. If you already have celiac disease, monitoring nutrient deficiencies (iron, vitamin D, B12, folate) is important for long-term health. However, a standalone genetic risk test for celiac without clinical confirmation (antibodies, biopsy) cannot guide longevity recommendations. Be cautious of overblown claims: the evidence here is mostly marketing. Consult a gastroenterologist if celiac is suspected.
