Palm oil shows up everywhere — in spreads, biscuits, instant noodles, chocolate, even shampoo — and it carries a heavy reputation. You've probably heard it's bad for your health and bad for the planet, full stop. The truth is more interesting, and a bit calmer. By the end of this, you'll know when palm oil is worth a second thought and when it really isn't.
Palm oil and your health: it depends on how much you eat
Palm oil is high in saturated fat — roughly half its fat is saturated. Diets heavy in saturated fat are linked to higher LDL ("bad") cholesterol over time. That's the core health consideration, and it's a real one — though what it means for you also depends on your overall diet and lifestyle, not on any single food.
But the dose matters more than the ingredient. A spoonful of palm oil in a biscuit you eat once a week is not the same as palm oil in something you eat daily. So the practical question isn't "is palm oil bad?" — it's "how often does this food land on my plate?"
- You eat a lot of it — a spread, cooking fat, breakfast cereal, kids' snacks: here saturated fat adds up, and it's worth comparing options.
- You eat a little — the occasional bar of chocolate or a treat: the palm oil in it is a small part of an already-occasional indulgence.
There's also a processing angle. When palm oil is refined at high temperatures, it can form contaminants such as 3-MCPD and glycidyl esters. Food authorities track these and set limits, and manufacturers have lowered them over the years. It's a genuine topic, not a reason to panic — and it's far more relevant in products eaten in large amounts, like fats for infants or everyday cooking, than in a rare treat.
Palm oil and the environment: efficient, but not innocent
Here's the part that surprises people. Per litre of oil, the oil palm is the most land-efficient crop we have — it yields several times more oil per hectare than soy, sunflower or rapeseed. Replace palm with another vegetable oil and you'd often need more land, not less, to make the same amount.
The problem isn't the plant — it's where new plantations went. Rapid expansion, mainly in Southeast Asia, drove deforestation of tropical rainforest and peatland, with real costs to wildlife and carbon storage. That history is why palm oil earned its reputation.
In response, certifications appeared. The best known is RSPO (Roundtable on Sustainable Palm Oil), which aims for palm grown without clearing high-value forest. It's a step forward, though its standards and enforcement have known limits, and "certified" doesn't mean "perfect." A simple boycott isn't the clean answer it sounds like — switching crops can shift the damage elsewhere rather than remove it.
How to spot palm oil on a label
Palm oil hides behind several names. Once you know them, they're easy to catch:
- Palm oil or palm fat — the direct version.
- Palm kernel oil — pressed from the seed; even higher in saturated fat than palm oil itself.
- Vegetable oil (palm) or "vegetable fats (palm)" — EU labels often name the specific oil in brackets.
- In cosmetics, it appears in INCI under names like Sodium Palmate, Sodium Palm Kernelate, Elaeis Guineensis Oil, or as a source for ingredients like Glycerin and Sodium Lauryl Sulfate — which is why palm in cosmetics is hard to avoid and rarely the main thing to weigh.
This is exactly the kind of label-reading Mira is built for. Scan a food product and its saturated fat gauge shows you, at a glance, whether the fat in it is something to weigh — without you having to decode the ingredient list yourself. The score is Mira's own opinion, meant to help you choose — not an absolute judgement of the product, a medical claim, or a statement about your health, which depends on how much and how often you eat something across your whole diet. Mira's method is its own and isn't endorsed or approved by any health authority.
The honest takeaway
Palm oil isn't a villain or a health food. For your body, it's about frequency: watch it in foods you eat often, relax about the occasional treat. For the planet, it's genuinely land-efficient, but its past is tied to deforestation, which is why certifications exist. Neither question has a tidy "always avoid" answer — and that's fine.
Tomorrow in the shop: pick up the one palm-oil product you buy most often — your spread, your cooking fat, your everyday biscuit — and check its saturated-fat figure against one alternative on the shelf. That single swap, on a food you eat a lot, does more than avoiding palm in a treat you have twice a year.
