Cocoa Powder

Food · Pantry & Condiment · Food, Typed Supps

The drinking chocolate without the three-quarters sugar. Almost nothing else changes.

Stage by stage

Bitter (Taste): The bitterness is the polyphenols — which is why sweetening it is what most products do.
Iron, inhibited (Gut): 30 mg per 100 g, non-haem, and partly blocked by cocoa’s own polyphenols.
Magnesium (Circulation): 590 mg per 100 g — among the densest sources in the library.
Theobromine (Brain): The main stimulant in cocoa, milder and longer-acting than the 150 mg/100 g of caffeine.

Timing

If the iron matters, keep it away from tea and coffee and pair it with something acidic. Cocoa partly inhibits its own iron absorption regardless.

Time to effect

Per 10 g: About 59 mg magnesium and 440 mg potassium.
Habitual: The mineral contribution is cumulative rather than acute.

Allergens

None of the fourteen major allergens. Derived from what this food is, not from a product label.

Eating patterns

Fits: Vegan, Vegetarian, Pescatarian, Halal, Kosher, Gluten-free. Depends on the product: Low-FODMAP.

Satiety

Not scored: the satiety index is measured on 240 kcal servings, and nobody eats a 240 kcal serving of this. The question does not apply rather than the answer being unknown.

Environmental footprint

46.7 kg CO2e and 3402 litres of freshwater per kg, matched to "Dark chocolate" in Poore & Nemecek (2018), Science 360.

Cost band

Pricey — roughly £14 per kg, as a band midpoint rather than a price.

Food vs. supplement

Cocoa powder against drinking chocolate is the cleanest before-and-after in the library. Same plant, same minerals — and one has been alkalised and cut with three parts sugar, which removes the polyphenols and adds 73 g of free sugar per 100 g.

Kitchen tip

Cocoa plus your own sweetener beats drinking chocolate on every axis, and lets you find the point where you stop noticing less sugar.

Common myth

“Hot chocolate powder and cocoa powder are basically the same thing.” In reality: One is 1.5 g of sugar per 100 g, the other 74.3 g. Drinking chocolate is mostly sugar with cocoa in it, and it is usually alkalised, which strips out most of the flavanols the cocoa research was about. Cocoa powder keeps the magnesium, potassium, iron and polyphenols, and lets you decide how sweet it ends up.
