What is palm oil and why is it debated?

Palm oil is a vegetable oil pressed from the fruit of the oil palm, and it is the most-produced vegetable oil in the world. It is debated for two separate reasons: its high share of saturated fat (health) and the link between its production and tropical deforestation (environment). Both are real, and both are open to exaggeration.

You will meet it in a very wide range of products, from chocolate spread and biscuits to margarine, instant soup, soap and shampoo. The reason it is everywhere is not a conspiracy but a handful of concrete technical advantages. Let us understand those first, then take the two debates one at a time.

What exactly is palm oil?

The oil palm (Elaeis guineensis) grows in hot, humid climates. The oil pressed from the fleshy outer part of its fruit is palm oil, while the oil from the kernel is palm kernel oil. Although both come from the same tree, their fatty acid profiles differ; palm kernel oil is even denser in saturated fat and is used more in cosmetics, coatings and some confectionery.

Crude palm oil has an orange tint; most products use the refined version with its colour and smell removed. On labels you sometimes see 'palm olein' or 'palm stearin': these are the liquid and solid fractions separated by cooling. Olein is more fluid and used in frying, while stearin is firmer and preferred in fillings, coatings and margarine-type products.

Why does industry use it so much?

• It is semi-solid at room temperature, so it gives texture without hydrogenation. Since it let manufacturers avoid the old hydrogenation method that produced trans fat, this was actually an improvement.
• It resists oxidation, so products stay unrancid longer and shelf life extends.
• Its taste and smell are neutral, so it does not carry its own aroma into the product and suits everything from chocolate to biscuits.
• Its yield per unit of land is high: the same amount of oil needs far less farmland than sunflower or rapeseed.
• It is cheap: the four points above together make it the default choice for a cost-pressured food industry.

The health side: it is about saturated fat

About half of palm oil's fatty acids are saturated (mostly palmitic acid). That share is clearly higher than olive or sunflower oil and somewhat lower than butter. So palm oil is neither 'innocent because it is plant-based' nor the worst of the fats; it sits somewhere in between.

The reason saturated fat is discussed rests on this mechanism: regular, high intake of saturated fat tends to raise LDL cholesterol in the blood, and high LDL is associated with cardiovascular disease risk. That is why health bodies recommend limiting saturated fat to a small share of total energy and, where possible, replacing it with unsaturated fats (olive oil, walnuts, hazelnuts, fish oil). The key word is 'replacing': cutting saturated fat and putting sugar and refined starch in its place brings no gain.

The most striking row is usually coconut oil: because it is 'natural' and fashionable it is assumed to be healthy, yet it is denser in saturated fat than palm oil. This shows why the topic cannot be reduced to 'this oil is bad, that one is good'. A biscuit containing a spoonful of palm oil is not harmful; eating several portions of palm-heavy processed products every day is a different picture.

Which names does it appear under on labels?

• Palm oil: the clearest wording, exactly what it says.
• Vegetable oil (palm), vegetable oils (palm, sunflower): when a blend is used, the source is given in brackets.
• Palm olein, palm stearin: the separated liquid and solid fractions of palm oil.
• Palm kernel oil: from the kernel of the same fruit, with an even higher share of saturated fat.
• Sodium palmate, sodium palm kernelate: the saponified form of palm oil in soaps.
• Glyceryl stearate, cetearyl alcohol, sodium lauryl sulfate: these can be palm-derived in cosmetics, but they can also be made from other plant sources.

Remember the ordering: ingredients are listed by weight, from most to least. If 'vegetable oil (palm)' sits second or third, the product contains a serious amount; if it appears near the end, the proportion is low. For the detail of the ordering rule, see our how to read an ingredient list guide.

Where does palm show up in cosmetics?

In cosmetics it is not palm oil itself but its derivatives that are used. In soaps, 'sodium palmate' provides hardness and lather quality; in creams, emulsifiers such as cetearyl alcohol and glyceryl stearate hold the texture; the raw material behind many cleanser surfactants can be palm kernel oil. There is no health debate here: the saturated fat content of an emulsifier applied to skin has nothing to do with heart health. The cosmetic debate is entirely environmental.

The environmental side: deforestation and certification

Palm oil production is heavily concentrated in the tropics. As demand grows, converting rainforest and peatland to open plantation area is linked with deforestation, habitat loss and carbon emissions. This is palm oil's most concrete and least disputed problem.

The response developed against it is certified production; the best known is the RSPO (Roundtable on Sustainable Palm Oil) system. Seeing 'sustainable palm oil' or an RSPO logo on a label means the supply chain is audited against those criteria. There is a counter-intuitive point here: boycotting palm oil entirely is not automatically better for the environment, because getting the same amount of oil from sunflower or rapeseed demands far more farmland. So the question is not 'palm oil' but 'palm oil produced how'.

Is a 'palm oil free' product automatically better?

No, because what replaces the removed oil decides the answer. If palm oil was taken out and coconut oil or fully hydrogenated fat put in, the saturated fat share may not have fallen at all and may even have risen. The wording 'palm oil free' tells you what is NOT in the product, not what is. The right reflex is to read the ingredient list and the saturated fat line on the back rather than the claim on the front.

A saturated fat budget: how much per day?

Without a concrete anchor, the advice to 'limit it' stays vague. The common recommendation from health bodies is to keep saturated fat below 10 percent of daily energy. For an adult taking in 2,000 calories a day, that works out at roughly 22 grams of saturated fat. You do not need to memorise the figure; what makes it useful is that it helps you judge whether the grams on a label are a lot or a little.

An example for scale: spreading two tablespoons of a chocolate spread containing 12 grams of saturated fat per 100 grams takes a noticeable share of the daily budget. That same calculation is unimportant for a one-off, and meaningful when it repeats every morning. This is exactly where the palm oil debate lands in practice: the question is not whether a product contains palm oil but how often and how much of it you eat.

Is palm oil better than trans fat?

This is important background for understanding why palm oil spread so widely. Industry used to apply partial hydrogenation to give liquid vegetable oils a firmer texture, and that process produced trans fat. The negative effect of trans fat on cardiovascular health was established more strongly than that of saturated fat, which is why partially hydrogenated oils have been restricted or banned in many countries.

Because palm oil is naturally semi-solid, it removes the need for hydrogenation. So the food industry's turn towards palm oil was partly a consequence of moving away from trans fat. That does not make palm oil 'good', but it places the debate in context: the choice is not 'palm oil or no fat' but 'palm oil or another solid fat'. If you see 'partially hydrogenated vegetable oil' on a label today, that phrase deserves more caution than palm oil does.

Frying and home use

Palm oil's resistance to oxidation makes it a stable fat at high temperatures, which is why it is common in industrial frying. At home the picture is different: olive oil and sunflower oil are already established options in Turkish kitchens, and there is no practical reason to buy palm oil as a separate bottle.

The point that really matters here is not whether you buy palm oil directly but how much of it you consume through ready-made products. Almost all the palm oil an average person takes in comes from packaged products rather than their own kitchen. So saying 'I do not buy palm oil' does not mean you are not consuming it. This is where the habit of reading labels comes in.

Eating out and bakery products

Reading labels does not help with unpackaged products. There is usually no ingredient list for a pastry from the bakery, a cream-filled item at the patisserie or something fried while eating out. In these products, concerns about cost and shelf life make margarine and palm-based solid fats common.

It is right to read this as a question of scale rather than a list of problems: a bakery item eaten once a week is not worth calculating, while the total shifts noticeably once it becomes part of every breakfast. Rather than trying to restrict what you cannot control, being consistent where you can (in the packaged products you choose at home) is a more sustainable approach.

A 30-second check at the shelf

• Look at the first five ingredients: if palm oil or 'vegetable oil (palm)' is among them, the product contains a noticeable amount.
• Read the saturated fat line in the nutrition table: check grams per 100 grams, not per portion.
• Compare two similar products on the shelf per 100 grams; shrinking the portion is the oldest way to make a label look good.
• Prioritise what you eat often: the spread you use every morning matters more than a biscuit eaten once a week.
• If the environmental side matters to you, look for RSPO or a 'sustainable palm oil' statement.

Common mistakes

• Assuming 'it is plant-based so it is healthy': being plant-based does not change the saturated fat share.
• Focusing on a single product: your weekly total of processed products decides more than the contents of one packet of biscuits.
• Treating a 'palm oil free' label as a quality guarantee: without checking what replaced it, the claim says nothing.
• Mistaking palm derivatives in cosmetics for a health issue: there the concern is environmental, not cardiovascular.

Who does it matter most to?

Total saturated fat matters more for people monitoring cholesterol, those warned by their doctor about cardiovascular risk, or those with a family history of early heart disease, and palm oil is part of that total. For readers who put environmental concern first, the certification statement is the deciding factor. For most other people the practical message is simple: make palm-heavy processed products an occasional item rather than a routine one.

In short

Palm oil is neither devil nor innocent. Because it is high in saturated fat it makes sense to count it in your total; because its environmental impact is real, certified production is a meaningful distinction. The most useful habit is reading the list and the saturated fat line on the back rather than the claims on the front.
