The evidence tells a more nuanced story. Genetic variants in CRP, IL-6, and TAS1R2 are associated with inflammation and sugar preference, which may influence skin aging indirectly. However, effect sizes are small, and direct causal links to visible skin aging are lacking. Robust evidence supports that overall lifestyle factors – a Mediterranean diet, sun protection, adequate sleep, and avoidance of smoking – have a far greater impact than any single gene or nutrient. Direct-to-consumer DNA tests can flag predispositions but cannot prescribe effective anti-aging nutrition. The evidence is rated 'human-moderate': observational and GWAS data exist, but interventional trials confirming genotype-specific dietary benefits for skin aging are scarce. Consumers should be wary of marketing that overstates the power of nutrigenetics for skin health.","area":"gesundheit","canonical_id":"gesundheit:canonical-fc7cbc41d48834e0fd9f27d4","id":"public-350d6282f752989ae430f616","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Lay opinion vs evidence: Hautalterung Ernährung","score":38.3672389,"snippet":"Lay opinion often claims that specific foods or supplements can directly reverse or prevent skin aging.
