The Lipid Digest

Reverse-engineering biology

From food and molecules to brain and body.

What does the science actually say about food, metabolism, and the brain-body connection? A working scientist reads the peer-reviewed literature — so you get the real story, not the headlines.

Stanford Scientists Regrew Cartilage by Preserving a Lipid Signal

Inhibiting 15-PGDH restores PGE₂ in arthritic joints — regenerating cartilage and reducing pain. The lipid signaling story behind a potential first disease-modifying treatment for osteoarthritis.

The Mediterranean diet is the most scientifically validated dietary pattern in human history. I grew up eating it in Campania — the region that gave the world mozzarella, ragù, and pizza. These posts pair traditional Southern Italian recipes with the peer-reviewed science behind why they work.

Alici di Cetara: The Ancient Roman Fish Sauce That's a DHA Delivery Vehicle

Colatura di alici — the amber liquid from salted anchovies in Cetara — is one of the most concentrated sources of EPA and DHA in the Mediterranean diet. Fermentation science, omega-3 biochemistry, and the recipe.

The Walnut: Why Every Mediterranean Kitchen Keeps a Bowl of Them

The only nut with significant omega-3 content — plus ellagitannins converted by gut bacteria to urolithins, dietary melatonin, and a polyphenol profile that rivals berries. The science, with a Campanian walnut pasta sauce.

OEA: The Lipid Molecule That Tells Your Brain You're Full

Every time you eat olive oil, your gut releases oleoylethanolamide. Here's what 20 years of research — including work from my own lab — reveals about how this tiny molecule controls hunger.

Alzheimer's Is Depleting Your Brain's 'Bliss Molecule'

Anandamide — your brain's natural cannabis-like compound — is significantly reduced in Alzheimer's disease. Here's what that means and where the research is heading.
