The Podcast That Explains the Body System Medicine Forgot
ECS Explained is the official podcast of ECS.education, hosted by Stefan Broselid — independent researcher in molecular pharmacology and neuroscience. Each episode builds the evidence-based case for why the endocannabinoid system belongs at the centre of modern medicine, physiology education, and public health conversation.
No supplement agenda. No cannabis politics. Just the primary literature, explained with the precision it deserves.
What Is the Endocannabinoid System?
The endocannabinoid system — ECS — is a regulatory network present in virtually every vertebrate on Earth. It controls metabolism, immune function, inflammation, sleep architecture, brain development, mood, appetite, and pain. It has over 76,000 peer-reviewed citations in the scientific literature. And it is missing from most medical textbooks.
Not because the evidence is not there. Because of what it was named. When researchers discovered this system in 1988, they were studying cannabis. The name they gave it carried a stigma that quietly kept it out of medical education for more than thirty years. ECS Explained exists to close that gap.
What to Expect
ECS Explained is long-form science. Each episode covers one aspect of ECS biology in depth — from the dietary fats that stock the molecular inventory the ECS depends on, to the developmental programming that begins in the womb, to how the ECS connects addiction, sleep, metabolism, psychiatric illness, and longevity into a single coherent biological story.
- How dietary fat balance programs the ECS from before birth
- Why omega-6 to omega-3 ratio may be an upstream driver of both metabolic disease and neurodevelopmental conditions
- How CB1 receptor availability connects addiction, sleep architecture, and cognitive aging
- Why the ketogenic diet’s diverse therapeutic effects may share a single ECS mechanism
- What PET imaging of CB1 receptors reveals about schizophrenia, withdrawal, and recovery
- How the ECS responds to exercise, social connection, gut microbiome health, and mindfulness
- Why measuring arachidonic acid in red blood cells may become a clinical biomarker for ECS tone
Episodes
Episode 001 — The Body System That Could Explain Two Modern Epidemics (And Why Medicine Never Taught It)
The endocannabinoid system has over 76,000 peer-reviewed citations and is absent from most medical school curricula. In this first episode, Stefan Broselid explains how dietary fat balance programs the ECS from before birth, why a skewed omega-6 to omega-3 ratio may be a shared upstream driver of both the global metabolic disease epidemic and the rise in neurodevelopmental conditions like ADHD and autism, and what the research on maternal nutrition during pregnancy reveals about how reward drive and social behaviour are wired in the womb.
Topics covered: Substrate-driven ECS model · Omega-6/omega-3 ratio · Fetal programming · Maternal nutrition · Metabolic syndrome · Neurodevelopment · ADHD · Autism · Sleep architecture · Gut microbiome · Medical cannabis · CB1 receptors

Episode 002 — The Diet That Keeps Winning — And Why Nobody’s Telling You the Real Reason
The Mediterranean diet has produced the same results in study after study for decades. Body weight down. Blood sugar down. Triglycerides down. Metabolic syndrome reversed. The recommendations are not controversial. What almost nobody explains is why this particular combination of interventions keeps working — what the single upstream biological problem is that all of them are correcting at once.
In this episode, Stefan Broselid traces the mechanism in full. Arachidonic acid — not omega-6 as a category, but this specific molecule — accumulates in cell membranes when dietary linoleic acid intake is high. It is the primary substrate for both the chronic inflammatory pathway and the peripheral CB1 overactivation that drives fat storage, insulin resistance, and fatty liver disease. Every effective component of the Mediterranean diet — EPA and DHA from fish, fibre, olive oil, vitamin D, exercise — corrects this substrate imbalance from a different angle. The episode also covers why a widely cited 2011 review claiming tissue arachidonic acid is not a concern measured the wrong tissue, why population-based reference ranges may be normalising a pathological state, and what 1.54 billion people with metabolic syndrome have to do with a fifty-year shift in the fatty acid composition of human body fat that no food label has ever been required to disclose.
Topics covered: Arachidonic acid · Membrane fatty acid composition · CB1 overactivation · Metabolic syndrome · Mediterranean diet · EPA and DHA · Linoleic acid · Phospholipase A2 · Visceral fat · Fatty liver disease · Gut microbiome · Akkermansia · Vitamin D · Exercise · Food labelling · Industrial seed oils

About the Host
Stefan Broselid is an independent researcher in molecular pharmacology and neuroscience, and the founder of ECS.education. His work focuses on the substrate-driven endocannabinoid system — the framework that the fatty acid composition of cell membranes is a primary controller of ECS function — with applications in neurodevelopmental medicine, metabolic disease, addiction, and sleep neurophysiology. He is developing a non-invasive biomarker for CB1 receptor availability and a non-cannabinoid formulation targeting ECS dysfunction in autism spectrum disorder and related conditions.
