We’ve been told that heart disease is a simple math problem: "Lower your ApoB at all costs." But the latest science suggests we’re looking at the scoreboard instead of the game. Your LDL particles aren't just numbers; they are structural delivery trucks. The real question isn't how many trucks are on the road, but what they are carrying and how stable they are. In Part 2 of our deep dive, we break down the 5 Pillars of Vascular Resilience

In the latest health podcasts, the message is clear: "Lower your ApoB at all costs and replace SFA with seed oils or face the consequences." But what if the number of trucks on the road isn't the problem? What if the problem is the cargo? In Part 1 of this series, we go "under the hood" of human biochemistry to debunk the mainstream narrative. We explore the Five Phases of the Lipid Loop

At this point, it’s worth asking: if polyunsaturated seed oils and plant sterols disrupt red blood cells, fuel oxidation, promote inflammation, and crystallise in plaques — then why are they still recommended as “cardioprotective”?

Explore the physiological link between seed oils, linoleic acid, and oxidized LDL. Learn how high triglycerides and metabolic dysfunction turn LDL into "explosive cargo," leading to arterial inflammation and plaque formation. A deep dive into MPO, LOX, and the real cause of heart disease.

What’s actually most prone to oxidation in LDL is the fatty acid tail of the cholesteryl ester in the “oil barrel” (and the PUFA in the phospholipid shell). Cholesterol itself — the rigid steroid ring — is remarkably stable. Pure cholesterol won’t just oxidise easily in the body.

When the metabolic environment is calm — low inflammation, low oxidative stress, good insulin sensitivity — LDL particles circulate, deliver nutrients, and return to the liver without incident. But in an inflamed environment, those same particles can get trapped, oxidised, and turned into plaque.

The simple claim “saturated fat raises LDL, therefore causes heart attacks” is outdated. A more accurate view must consider biochemistry, particle quality, metabolic health, and dietary context.

Saturated fat became a convenient scapegoat, while the role of refined carbohydrates, ultra-processed foods, and chronic inflammation in driving heart disease was largely overlooked.
