The fats we actually cooked with

Strip away the last hundred years and the fats humans actually cooked with were a short, almost boring list: butter and ghee, beef tallow and lard, olive oil, a little coconut where it grew. Boring is exactly the point. These are the fats we ate for thousands of years, and our bodies are built around them.

Why they’re stable

What they all share is chemistry. Animal fats and olive oil are mostly saturated and monounsaturated — the sturdy, single-linked kind that shrug off oxygen, the opposite of the fragile polyunsaturated oils from the oxidation piece. You can heat them, store them and cook with them without them quietly falling apart. That’s not romance about the old days; it’s the reason they kept in a kitchen that had no refrigerator.

You could make them yourself

A jar of tallow is just rendered fat — heat and time, nothing else. Butter is churned cream. Olive oil is pressed olives. Any of them could be made in an ordinary kitchen, and for most of history they were. Set that beside getting oil out of a soybean, which takes an industrial plant, high heat, pressure and chemical solvents. One is food. The other is a manufacturing process that happens to end in a bottle.

Not a superfood — just a baseline

None of this means butter is a miracle or that you should pour tallow over everything. It’s simpler than that: these are the fats humans are adapted to, they’re stable in heat and time, and they carry the fat-soluble vitamins — A, D, E and K — that we actually need. Choosing them isn’t a wellness trend. It’s a return to a default that only got abandoned because something cheaper showed up.

So when people ask what on earth they’re supposed to cook with instead, the answer isn’t exotic or expensive. It’s the fats your kitchen would have stocked a century ago. Turning that into an everyday habit — what to buy, what to reach for when — is the whole job of Practice.
