Palm oil, plainly

Palm oil is in almost every Nigerian pot, and it has an odd reputation: revered at home, treated abroad as something to avoid. Most of that confusion comes from two different arguments being run together — one about the oil in your kitchen, and one about how the world's supply is grown.

They are worth separating.

Red is not the same as clear

The deep orange-red oil sold in markets is crude red palm oil, pressed from the fruit and otherwise left alone. That colour is the important part: it comes from carotenoids, the same family of pigments that make carrots orange, and red palm oil contains more of them than any other common food. Your body turns them into vitamin A.

It is also unusually rich in vitamin E — specifically in a form called tocotrienols, which is uncommon in ordinary cooking oils.

The pale, clear oil sold as vegetable or palm olein has been refined, bleached and deodorised. It is the same crop, but the carotenoids and much of the vitamin E have been stripped out. It is a cooking fat and nothing more.

If you are buying palm oil for what it gives you, buy the red one.

Heating it past a point defeats the purpose

Here is the practical bit most people are never told.

Those carotenoids are fragile. Heat red palm oil hard — until it goes clear and starts smoking, the way it is often bleached deliberately before frying — and you destroy them. The colour leaving is not cosmetic; it is the vitamin A precursor being burned off in front of you.

Cooked gently, stirred into a soup, warmed rather than scorched, red palm oil keeps most of what makes it worth having.

There is a second reason to avoid overheating it: taking any oil past its smoke point breaks it down into compounds you would rather not be eating. Neither the nutrition nor the flavour survives.

The saturated fat question

Palm oil is roughly half saturated fat. That is high — much higher than groundnut or sunflower oil, lower than coconut oil or butter.

The honest position is that this is not settled science, and anyone giving you a confident one-line verdict is overstating what is known. Saturated fat's effect on heart disease has been argued over for decades and is still being argued over. What is not in dispute is quantity: palm oil is a fat, all fats are calorie-dense, and how heavy a Nigerian meal sits has far more to do with how much oil went in than with which oil it was.

The useful advice is boring and reliable. Use it, use the red kind, do not burn it, and be aware of how much is going into the pot — because that is the number that actually moves.

The environmental part is a separate argument

Palm oil is criticised internationally mainly for deforestation — the clearing of rainforest in Indonesia and Malaysia for industrial plantations, and the loss of habitat that comes with it. That is a real problem and a serious one.

But it is an argument about industrial monoculture on the other side of the world, not about the oil itself, and not about the West African smallholder farming where the crop originated. Oil palm is native to this region. It has been grown and pressed here for thousands of years, at a scale that never cleared a rainforest.

Two different questions. It is fair to take the second one seriously without letting it tell you anything at all about what is in your pot.
