Ein weiterer Mythos: Die Darmflora habe keinen Einfluss auf HDL. Neuere Forschung zeigt jedoch, dass bestimmte Darmbakterien kurzkettige Fettsäuren produzieren, die den HDL-Stoffwechsel modulieren können. Allerdings ist die Evidenzlage noch überwiegend mechanistisch und aus Tiermodellen; große Humanstudien fehlen. Fakt ist: Ein gesunder Lebensstil mit Ballaststoffen, Omega-3-Fettsäuren und Bewegung unterstützt sowohl HDL-Funktion als auch Darmgesundheit. Consumer-Tests, die angeblich den HDL-Wert oder die Darmflora isoliert bewerten, sind oft irreführend – sie messen nur Konzentration, nicht Funktion.

Fact: A healthy gut, especially high microbial diversity and adequate short-chain fatty acid (SCFA) production (e.g., butyrate), can positively influence HDL metabolism. SCFAs upregulate ABCA1 transporters in intestinal cells, supporting HDL formation. Gut bacteria also modulate bile acid metabolism, indirectly affecting HDL. Myth: A high HDL level always protects against cardiovascular disease. Recent evidence shows HDL function (e.g., cholesterol efflux capacity) matters more than concentration. Dysbiosis can produce pro-inflammatory HDL that loses its protective properties. The evidence is mostly mechanistic and observational; robust randomized controlled trials linking gut health to HDL and then to cardiovascular outcomes are lacking. Consumer DNA or microbiome tests claiming direct links between single gene variants (e.g., VDR) and HDL should be viewed skeptically—effects are small and context-dependent. Bottom line: Supporting gut health through a high-fiber Mediterranean diet may improve HDL, but a high HDL number alone is not a reliable shield.
