VLDL

Definition

Very Low-Density Lipoprotein is a lipoprotein particle produced by the liver that carries triglycerides through the bloodstream and is associated with increased cardiovascular risk.

How it works

VLDL particles are synthesized by the liver and are particularly rich in triglycerides, carrying approximately 55-65% triglyceride content by weight. As VLDL circulates in the bloodstream, triglycerides are gradually removed by tissues, converting VLDL into intermediate-density lipoprotein (IDL) and eventually LDL cholesterol. High VLDL levels indicate excessive triglyceride production, typically from overconsumption of refined carbohydrates, added sugars, and alcohol. Like LDL, elevated VLDL contributes to atherosclerosis and increases cardiovascular disease risk.

Role

VLDL transports triglycerides from the liver to tissues and gradually converts to LDL cholesterol, playing a significant role in atherosclerosis development.

Examples

• Excess refined carbohydrates and sugary drinks
• Alcohol consumption, especially in excess
• Processed foods high in added sugars and saturated fats

Recommendations

Reduce refined carbohydrate and added sugar consumption to lower VLDL production by the liver. Limit alcohol intake and increase fiber intake through whole grains, fruits, and vegetables. Regular physical activity helps reduce VLDL levels by promoting triglyceride utilization.

Key takeaway

Controlling VLDL through reduced refined carbohydrate intake is essential for lowering triglyceride levels and protecting cardiovascular health.
