Morocco

Amazigh families in southwestern Morocco drizzle argan oil on nearly everything they eat.
Most Americans have only ever rubbed it on their hair.

Argan oil  ·  Argania spinosa  ·  Mechanism: phytosterol competition

The argan tree is native to southwestern Morocco and parts of Algeria, Mauritania, and Western Sahara, but its culinary heartland is a dry, rocky band of land between the cities of Agadir, Essaouira, and Taroudant. The Amazigh people of this region have been cracking its fruit, pressing its oil, and eating it as a daily fat for centuries.

The preparation has barely changed. Women split the hard outer shell with flat stones, roast the inner kernels over low fire until they turn dark and fragrant, grind them on a stone mill, and press the thick paste by hand until the oil separates.

That roasted oil is the finishing fat of the daily table, not a cosmetic. It goes over bread, couscous, vegetables, and salads, and gets stirred with ground almonds and honey into a thick paste called amlou, served at breakfast and at celebrations.

A second version, pressed from raw unroasted kernels, is the one made for skin and hair, but in the Amazigh kitchen argan oil has always meant food. UNESCO designated the argan forest a Biosphere Reserve in 1998 and inscribed Amazigh argan practices on the Intangible Cultural Heritage list in 2014.

Argan oil carries a plant sterol profile unlike any common cooking oil. About 75 to 88% of its sterols are schottenol and spinasterol, two compounds nearly absent from olive oil and sunflower oil, which are dominated by a different sterol called sitosterol.

In the small intestine, dietary cholesterol has to ride inside tiny clusters called bile salt micelles to get absorbed into the bloodstream. Schottenol and spinasterol are shaped enough like cholesterol to crowd into those same clusters and physically shove it out, so less cholesterol makes it through the intestinal wall and into circulation.

The West turned argan oil into a hair serum. The sterols that lower cholesterol work in the intestine, not on the scalp.

A meta-analysis of five randomized controlled trials, published in Phytotherapy Research and covering 292 participants, tested the whole culinary oil eaten as food, not a sterol extract or capsule. Daily consumption at roughly 20–25 milliliters significantly reduced total cholesterol, LDL cholesterol, and triglycerides.

The how-to

This is a finishing oil, not a cooking project. One bottle, a daily drizzle, no recipe required.

Buy culinary argan oil, labeled "food-grade," "culinary," or "roasted," not cosmetic grade. Several Moroccan brands sell it on Amazon for roughly $25 to $45 per 8-ounce bottle, about a 10-day supply at daily use.
Drizzle about 1.5 tablespoons (roughly 22 mL) per day over couscous, grain bowls, roasted vegetables, or salads. For a simple amlou, stir a tablespoon of argan oil into a spoonful of almond butter with a drizzle of honey and spread it on toast.
The oil tastes toasty and nutty, noticeably stronger than olive oil. The clinical trials measured lipid changes at three to four weeks of daily use, so check your next blood panel after consistent use rather than expecting changes you can feel.
If you have tree nut allergies, check with your allergist first, as cross-reactivity has been reported. Do not substitute argan oil for prescribed cholesterol medication, and for persistent or worsening lipid concerns, see your doctor.
