Die Erhöhung von HDL durch Medikamente (z. B. CETP-Hemmer) senkte in großen Studien nicht die Ereignisrate. Für die Langlebigkeit sind andere Faktoren wie Entzündungsstatus, Insulinsensitivität und Telomerlänge vermutlich relevanter. Der Kontext zu DNA-Tests (MY FOOD BOOK) und APOE4 zeigt, dass genetische Risikofaktoren wie APOE4 die HDL-Funktion beeinflussen können, aber die Interpretation einzelner Genvarianten für die Lebenserwartung bleibt spekulativ.

The function of HDL – its ability to promote reverse cholesterol transport and exert anti-inflammatory effects – may matter more than the absolute level. Lifestyle factors like regular exercise, moderate alcohol intake, and a Mediterranean diet can raise HDL naturally, but their longevity benefit likely comes from multiple pathways, not HDL alone. For most people, having HDL in the normal range (men >40 mg/dL, women >50 mg/dL) is favorable, but extremely high levels are not necessarily protective and may even signal dysfunction.

Evidence shows triglycerides are strongly influenced by lifestyle (diet, exercise, alcohol, weight) and often cluster with other risk factors (LDL, HDL, insulin resistance). Randomized controlled trials proving that isolated triglyceride reduction prolongs life are lacking. Genetic factors also play a role: variants in genes like APOA5, LPL, or FADS1 can modulate triglyceride levels, but their effect on longevity is modest and not clinically actionable. Consumer DNA tests that report such variants often overstate clinical relevance. Bottom line: Triglycerides are an important biomarker but not a standalone predictor of longevity.
