Triglycerides

DETriglyzeride

Triglycerides are the main way your body stores fat, from your diet and from what your body makes. They travel in your blood inside fat-carrying particles. The main ones are VLDL, chylomicrons, IDL, and their remnants. Fasting triglycerides climb with insulin resistance, too many refined carbs, alcohol, and metabolic syndrome. High levels mean more of those triglyceride-rich 'remnant' particles. And the cholesterol they carry (remnant cholesterol) is a proven cause of artery disease, shown by Mendelian randomization. Lower fasting triglycerides go with better insulin sensitivity and lower heart risk.
