What is HDL size?

High-Density Lipoprotein (HDL) size refers to the average diameter of high-density lipoprotein particles in the blood.‍HDL particles come in varying sizes, with larger particles generally being more effective at reverse cholesterol transport.‍

What does it assess?

HDL size assesses cardiovascular health and lipid metabolism.‍It can be measured through advanced lipid testing and is used as a marker for assessing cardiovascular health.‍An optimal HDL size can indicate efficient cholesterol metabolism and reduced cardiovascular risk.

How can I optimize my HDL size?

Omega-3 fatty acids, found in fatty fish like salmon and plant sources like flaxseeds, help increase HDL particle size and improve overall lipid profiles.‍Monounsaturated fats from sources like olive oil and avocados can also support healthy HDL function. Physical activity, especially moderate to intense aerobic exercise, is effective at improving HDL size and functionality.‍Exercise boosts HDL particle formation and promotes a healthier lipid profile. Limiting added sugars and refined carbs can help improve HDL levels and particle size by reducing triglycerides, which in turn supports a healthier lipid environment.

What do large and small HDL sizes mean?

Larger HDL particle size is generally associated with effective cholesterol transport and reduced cardiovascular risk.‍Large HDL particles are more efficient in reverse cholesterol transport, helping to remove excess cholesterol from arteries and reducing the risk of plaque buildup.‍Smaller HDL particle size may indicate reduced cholesterol transport efficiency, potentially raising cardiovascular risk.‍Low HDL size can be associated with factors like insulin resistance, metabolic syndrome, and an overall pro-inflammatory state.
