What role does Triglyceride play in longevity?

The provided context does not contain specific information on the role of triglycerides in longevity. Generally, triglycerides are a key biomarker of lipid metabolism. Elevated fasting levels (>150 mg/dL) are considered a risk factor for cardiovascular disease, which can impact lifespan. Evidence from epidemiological studies shows a moderate association, but direct causal evidence for longevity is limited. Lifestyle factors such as diet, exercise, and weight management have a stronger influence on triglyceride levels than individual genetic variants. MyBody-X tests can offer insights but not a diagnosis. The effect sizes are small and ancestry-specific, so results should be interpreted cautiously.
