Peru

Peru never ate raw maca.
The supplement industry does.

Maca root  ·  Lepidium meyenii  ·  Mechanism: glucosinolate degradation

Maca has been grown on the Junín plateau, at roughly 4,000 meters above sea level, for around three thousand years. The communities that grew it always processed it before eating. They dried the root in the sun for weeks. They boiled it. Some fermented it into a thick porridge called mazamorra.

Fresh, unprocessed maca root was not eaten. This was not inconvenience. It was knowledge.

Raw maca contains glucosinolates, the same class of compounds found in broccoli and cabbage. In moderate amounts they are fine. In concentrated supplement doses from raw powder, they interfere with iodine uptake in the thyroid. The traditional drying and boiling process degrades them significantly.

There is a second problem. The active compounds in maca, a group called macamides, are locked inside a dense starch matrix. Without breaking that structure, most passes through unabsorbed. Heat processing, what is called gelatinization, dissolves the starch and frees the macamides.

Raw maca labels it "premium." The processing that works labels it "gelatinized."

The supplement industry sells raw maca as the purer option. The word "raw" implies nothing was removed. In this case, nothing was removed that should have stayed. And nothing was done that needed to be done.

The how-to

The traditional preparation is a warm drink, not a capsule. It takes two minutes.

Buy gelatinized maca. The label will say "gelatinized" or "pre-cooked." Avoid raw.
Add one teaspoon to warm oat milk or cacao. It needs to be warm: the starch stays broken down with heat.
Add a small amount of fat. Macamides are fat-soluble. A teaspoon of coconut oil or full-fat milk is enough.
Drink in the morning. That is when the Junín communities used it, before physical work.

Tomorrow: a practice from Georgia
that Western dairy science finally caught up to.

See you then.
