Last August, I wrote about a troubling pattern in inflammation research: brilliant scientists studying arachidonic acid metabolism while remaining “blissfully unaware that half the arachidonic acid story exists in a parallel research universe.” I documented how eicosanoid researchers and endocannabinoid scientists study the same substrate, same concentration ranges, same tissues—yet publish in…

2025 in ECS Research: The Year the Substrate-Driven ECS Model Came of Age
Endocannabinoid system substrate—specifically membrane fatty acid composition—is the primary determinant of CB1 receptor function, not genetics or receptor density. For years, I’ve been making the case that endocannabinoid system function is not primarily about receptor density or genetic variants, it’s about substrate availability. The composition of fatty acids in cell…

The Biochemical Plateau: Rethinking Linoleic Acid and Heart Health
The Linoleic Acid Paradox: Protection or Peril? For decades, linoleic acid has enjoyed a privileged place in nutritional policy. It is the cornerstone of “heart-healthy” messaging, the molecular mascot of seed oils, and the quiet passenger in countless processed foods. But beneath this reputation lies a paradox: the very molecule…

Soybean oil, linoleic acid, and the gut ECS
A recent study titled ‘Diet high in linoleic acid dysregulates the intestinal endocannabinoid system and increases susceptibility to colitis in Mice‘ shows that eating a lot of linoleic acid from soybean oil changes lipid chemistry in the gut in a way that weakens the protective endocannabinoid system and strengthens inflammatory…

Too Much Omega-6? New Link Shows Linoleic Acid Directly Flips a Master Metabolic Switch
Discover how dietary linoleic acid (LA), a major omega-6 fat, directly activates the master metabolic switch mTORC1 through a newly found pathway involving FABP5. Explore the implications for Metabolic Syndrome, potential interactions with the endocannabinoid system (ECS), and what this means for understanding modern diets.

Omega-6, Mortality, and Your ECS: Unpacking the Latest UK Biobank Bombshell
A major UK Biobank study found higher plasma linoleic acid (LA) linked to lower mortality, seemingly contradicting concerns about high dietary omega-6 driving ECS dysfunction. This post unpacks the findings, distinguishing between plasma snapshots and tissue arachidonic acid (AA) realities, and explains why the omega-6/omega-3 balance and ECS perspective remain crucial for understanding metabolic health.

The Silent Saboteur: How Modern Diets Hijack Your Body’s Master Regulator (While Science Looks Away)
Discover how ‘heart-healthy’ seed oils may hijack your body’s ancient metabolic regulator—the endocannabinoid system—driving obesity, mental health crises, and neurodevelopmental disorders. Explore why 50 years of nutrition research ignores this critical connection.

Dietary Fats – More Than Just Sources of Energy
Fats are more than just calories—they shape our biology. Learn how dietary fats like omega-6 and omega-3 influence health through the endocannabinoid system and why choosing the right fats is key to a healthier future.
