The TyG index is a validated surrogate for insulin resistance that performs comparably to HOMA-IR without requiring fasting insulin.
The TyG index is a validated surrogate for insulin resistance that performs comparably to HOMA-IR without requiring fasting insulin. It is also a strong independent predictor of non-alcoholic fatty liver disease, cardiovascular events, and all-cause mortality.
Dietary excess of refined carbohydrates and saturated fats, physical inactivity, obesity, metabolic syndrome, type 2 diabetes. Genetic dyslipidaemia can elevate TG independent of metabolic health.
Usually asymptomatic at moderate elevations. Very high values (high TG): xanthomas, eruptive skin lesions, pancreatitis risk.
Omega-3-rich fatty fish (salmon, mackerel, herring), leafy greens, legumes, whole oats, low-sugar fruits. Post-meal activity reduces postprandial TG spikes.
Sugar, particularly fructose from juices and sweetened beverages. Alcohol markedly raises triglycerides. Refined starches and trans fats compound the effect.
