Episode notes

Phospholipids break off from the cholomide crons as they're undergoing what we call lipolysis, hydrolyzing their triglycerides. Once there's a particle shrink, apo-e assumes sort of a different conformation. Apo-e happens to be a major ligand for the two receptors in the liver that clear apo-b particles. So if you get a blood test and you want to measure chylomicrons, it has to be a postprandial blood test.

Episode #251. Cardiovascular disease is one of the biggest killers in the Western world, and it’s vital that we understand cardiovascular health in order to improve lifespan and healthspan. In this episode, I sit down with Dr Thomas Dayspring for Part One of a three-part deep dive into cardiovascular disease and blood lipids. In this introductory episode, we examine how our body absorbs lipids and transports them throughout the body – and what happens when it goes wrong.

Specifically, we discuss:
