In my kitchen in Abia State, Nigeria, palm oil arrives as deep red oil in a keg, poured straight into the soup pot. On supermarket shelves, the same fruit hides inside biscuits, margarine and chocolate as a pale, refined fat. Palm oil in processed foods is a different product doing a very different job.
Food manufacturers rely on refined palm oil because it is solid enough to give texture, stable enough to last, and cheap enough to use at scale.
Those same qualities have made it one of the most argued-about ingredients in the world.
We bring to you, the many jobs palm oil does in processed foods, the products it usually appears in, and how labels name it.
This post also weighs the main controversies, from saturated fat and process contaminants to infant formula, forests, and palm oil-free labels.
Each claim on this page links directly to the published research behind it.
Prefer palm oil the way West African kitchens have always used it, red, unrefined and fresh from the farm? You can order real red oil, no factory needed from the shop page.

What Is Palm Oil in Processed Foods?
Palm oil in processed foods means refined palm oil and its fractions, used by manufacturers as an ingredient rather than as a cooking oil at home.
It is usually refined, bleached, and deodorized, so it carries no red color, no smell, and almost no taste.
Factories split it into a liquid fraction called palm olein and a firmer fraction called palm stearin, then blend them for each product.
Palm kernel oil, from the seed, also appears in many foods, especially confectionery and ice cream. Together, these fats give packaged foods texture, stability and a long shelf life.
How refining produces olein, stearin and other fractions is covered in palm olein and stearin in detail.
How Common Is Palm Oil in Processed Foods?
A popular claim says palm oil is in about half of all supermarket products. Research published in 2025 suggests that figure has never had public evidence behind it.
A 2025 study in Environmental Research: Food Systems checked about 1,600 food products from supermarket chains in the Netherlands, the UK and Australia. Only about 7.9 percent of them explicitly listed palm oil or palm kernel oil.
The same study found maize, rapeseed and soya oils more common than palm oil in those shops.
It estimated that up to 40 percent of products might contain palm oil, through unnamed vegetable oils or oleochemicals.
| Finding from the 2025 study | Share of food products |
|---|---|
| Explicitly listing palm or palm kernel oil | About 7.9 percent |
| Listing maize oil | About 19 percent |
| Listing rapeseed oil | About 15 percent |
| Listing soya oil | About 14 percent |
| Possibly containing palm through unnamed ingredients | Up to about 40 percent |
These figures come from three Western supermarket chains, so shops in Asia or Africa may look quite different.
In Nigeria, I believe many cookies and crackers contain palm oil, and their labels are worth checking.
Why Manufacturers Use Palm Oil
Palm oil does several jobs at once, which few other single oils can match. The Malaysian Palm Oil Board reports that about 80 percent of palm oil products and fractions go into food formulations.
| Job in the food | Why palm oil suits it |
|---|---|
| Giving texture and body | It is semi-solid at room temperature, so it firms spreads, fillings and doughs |
| Replacing trans fats | It is naturally firm, so it needs no partial hydrogenation |
| Lasting on the shelf | Its saturated and monounsaturated fats resist oxidation better than many liquid oils |
| Frying at scale | Refined palm olein stays stable through long, hot frying |
| Staying neutral | Refining removes color, smell and taste, so other flavors lead |
| Melting in the mouth | Its fractions can be blended to melt at body temperature |
| Keeping costs low | The oil palm yields large amounts of oil from each hectare |
The same board lists margarine, shortening, vanaspati, cooking oil and confectionery fats as its main food applications. Each of those products uses a different blend of palm fractions and other fats.
The Trans Fat Story
Palm oil’s place in processed foods grew sharply when trans fats fell out of favor. Trans fats came mainly from partially hydrogenated oils, which manufacturers once used to firm liquid vegetable oils.
The US Food and Drug Administration determined in 2015 that partially hydrogenated oils were no longer generally recognized as safe. Manufacturers could not add them to foods after June 18, 2018, with some extensions.
A 2014 article in Today’s Dietitian describes how manufacturers turned to palm oil as a naturally trans fat-free replacement. It reports that US palm oil imports rose by nearly 60 percent over the previous seven years.
The swap solved one problem but raised another, since palm oil is high in saturated fat. That trade-off sits at the heart of the health debate covered below.
Foods That Commonly Contain Palm Oil
The table below lists product types where palm oil or palm kernel oil frequently appears. Recipes vary by brand and country, so always check the label of the product in your hand.
| Food | What palm oil does there | How the label may show it |
|---|---|---|
| Margarine and spreads | Firms the spread without hydrogenation | Palm oil, palm fat, vegetable fat |
| Biscuits, cookies and crackers | Gives crunch, crumb and shelf life | Palm oil, vegetable fat, shortening |
| Pastries, cakes and doughnuts | Makes layers flaky and holds texture | Palm oil, shortening, vegetable fat |
| Chocolate and confectionery | Controls melting and snap | Palm oil, palm kernel oil, vegetable fat |
| Ice cream and frozen desserts | Gives creaminess and body | Palm kernel oil, vegetable fat |
| Instant noodles | Used in frying many pre-fried noodle blocks | Palm oil, vegetable oil |
| Crisps and fried snacks | Stable frying oil | Palm oil, palm olein, vegetable oil |
| Non-dairy creamers and whipped toppings | Replaces dairy fat | Palm kernel oil, vegetable fat |
| Bread and baked goods | Keeps the crumb soft and extends freshness | Palm oil, vegetable fat |
| Infant formula | Supplies palmitic acid found in breast milk | Palm olein, vegetable oils |
My household does not eat instant noodles, though for reasons that have nothing to do with palm oil.
How Palm Oil Appears on Food Labels
Labels name palm oil in many ways, depending on the country, the product and the fraction used. Learning the common names makes palm oil far easier to spot on any pack.
| Label name | What it is |
|---|---|
| Palm oil, palm fat | Refined palm fruit oil |
| Palm olein | The liquid fraction, used for frying and cooking oil |
| Palm stearin | The firm fraction, used in margarine and shortening |
| Palm kernel oil, palm kernel fat | Oil from the seed, used in confectionery and ice cream |
| Hydrogenated or fractionated palm kernel oil | Kernel oil processed for firmer confectionery fats |
| Vegetable oil or vegetable fat | May include palm, depending on local labeling rules |
| Shortening | A solid baking fat that may be palm based |
| Interesterified fat | Fat blends rearranged for texture, frequently palm-based |
| Mono- and diglycerides of fatty acids, E471 | Emulsifiers that may come from palm or other fats |
Emulsifiers such as E471 can come from palm, soya, sunflower or animal fats, so the label alone may not tell you.
Palm-derived ingredients in cosmetics use a different set of names, covered in palm names on cosmetic labels.
Labeling Rules Differ by Country
In the European Union, refined vegetable oils may be grouped on a label, but each specific plant source must still be named.
Annex VII of EU Regulation 1169/2011 sets that rule, and it took effect in December 2014.
In the United States, labels may list oils that are only sometimes used, if marked with words such as “and/or”.
The US regulation on ingredient labeling gives the example of a shortening that contains one or more of cottonseed, palm or soybean oil.
| Region | What the label must say |
|---|---|
| European Union | Each vegetable oil source named, even when grouped |
| United Kingdom | Retained version of the same EU rule |
| United States | Oils may be listed with “and/or” when not always present |
Rules in other countries vary, so a plain “vegetable oil” on a label may or may not include palm.
The Controversies Around Palm Oil in Processed Foods
Palm oil draws criticism on several fronts, and the research behind each one differs in strength.
Saturated Fat and Cholesterol
Palm oil is roughly half saturated fat, far more than most liquid vegetable oils. A 2021 umbrella review in Nutrients found palm oil raised LDL cholesterol compared with oils rich in unsaturated fats.
The same review called the effect of plant saturated fats on heart disease itself inconclusive. The fuller picture, including the saturated fat debate, sits in the full health research summary.
Process Contaminants From Refining
High refining temperatures can create process contaminants called glycidyl esters and 3-MCPD esters.
The European Food Safety Authority reported in 2016 that palm oils and fats carried the highest levels of these compounds among the oils it assessed.
EFSA found glycidol genotoxic and carcinogenic and set no safe level for it. It also noted that glycidyl ester levels in palm oils and fats roughly halved between 2010 and 2015, after voluntary action by producers.
EFSA named margarines, pastries and cakes as the main sources of exposure for consumers aged three and above. These contaminants come from refining, so unrefined red palm oil is not the product in question.
Palm Olein in Infant Formula
Many infant formulas use palm olein to supply palmitic acid, a major fat in breast milk. A 2020 review in Nutrients found most studies reported lower calcium and fat absorption with palm olein formulas.
The review also found harder stools with those formulas, and one trial reported lower bone mineral content at about six months. Three of its four authors worked for Abbott Nutrition, a formula maker, so readers should weigh that context.
Forests and Wildlife
The loudest controversy is environmental, because large plantations in Southeast Asia have replaced tropical forests. Much of the oil in Western processed foods comes from those plantations.
The research on deforestation, peat and wildlife, alongside the case for certified and smallholder oil, is set out in the deforestation debate in full. Certification schemes and their limits are covered in what the RSPO label means.
Palm Oil Free Labels
Some brands now print palm oil free on their packs, but researchers question how much such claims tell shoppers. A 2015 article in the European Journal of Risk Regulation argued that such claims can be misleading in the EU.
Its reasoning is that EU labels already name every vegetable oil, so the claim adds nothing that the ingredient list does not show.
Swapping palm for other oils also changes texture and land use, as covered in oils that replace palm oil.
| Controversy | What research shows | Strength of evidence |
|---|---|---|
| Saturated fat and LDL cholesterol | Palm oil raises LDL compared with unsaturated oils | Consistent for LDL, unclear for heart disease |
| Refining contaminants | Palm fats carry the highest levels among oils assessed | Strong on levels, with falling trends |
| Infant formula | Lower calcium and fat absorption with palm olein | Moderate, with industry authored reviews |
| Deforestation | Plantation expansion has cleared forests in Southeast Asia | Strong, though varied by region and period |
| Palm oil free claims | Can mislead where oils must already be named | Legal argument rather than scientific finding |
Red Palm Oil Is a Different Product
Almost every controversy above concerns refined palm oil in factory foods, not the red oil cooked in West African homes.
Red oil skips bleaching and deodorizing, so it keeps its natural carotenoids and avoids the high heat stage behind refining contaminants.
It still carries the same saturated fat, so it is no free pass on that point. How red, crude, refined and kernel oils differ is set out in red, crude, refined and kernel oil.
How to Read a Food Label for Palm Oil
A few simple steps make it easy to see what fat is in a packaged food.
- Find the ingredients list. Ingredients appear in order of weight, so fats near the top make up a large share.
- Look for palm names. Check for palm oil, palm olein, palm stearin, palm kernel oil and palm fat.
- Read vegetable oil carefully. In the EU and UK, the sources should follow in brackets, while elsewhere they may not.
- Check the emulsifiers. E471 and similar emulsifiers may come from palm, but the label may not say.
- Look for certification marks. An RSPO mark shows certified palm oil, while palm oil free shows the brand avoided it.
Palm-based ingredients also reach far beyond food, into soaps, cosmetics and fuels, as covered in palm oil beyond the food aisle. The industrial chemicals made from palm are listed in palm derivatives and their uses.
What Studies Says About Palm Oil in Processed Foods
Research on palm oil in processed foods centers on how common it is, why manufacturers use it, and what it means for health. Five sources stand out for shoppers, cooks and anyone following the debate.
The 2025 supermarket study found palm or palm kernel oil explicitly listed in about 7.9 percent of foods sampled. The Malaysian Palm Oil Board reports that about 80 percent of palm products go into food formulations.
The FDA ban on partially hydrogenated oils, effective from 2018, pushed manufacturers toward palm oil. EFSA found the highest levels of refining contaminants in palm fats, with glycidyl ester levels falling by about half.
The 2021 umbrella review linked palm oil to higher LDL cholesterol, with heart outcomes unresolved. The 2020 infant formula review found lower calcium absorption with palm olein.
These sources have clear limits worth stating plainly for every single reader. The supermarket study covered only three
Western chains, so other regions may differ. The industry board and formula maker authors have commercial interests, and EFSA’s figures date from 2016.
Conclusion
The red oil in my soup pot and the pale fat in a packet of biscuits come from the same fruit, yet they are very different products.
Manufacturers prize refined palm oil for its texture, stability, neutral taste and low cost. Those benefits come with real debates over saturated fat, refining contaminants, infant formula and forests.
Palm oil is also less universal than the popular half of all products claim suggests. Read the ingredients list on your next packaged food, and you will see exactly where palm oil sits.
