Why Is Palm Oil in Everything? The Real Reasons

Palm oil shows up in roughly half the packaged products on supermarket shelves, from cookies and instant noodles to shampoo and laundry detergent, because it sits at a rare intersection of cheap, versatile, and physically irreplaceable. No other vegetable oil is naturally semi-solid at room temperature, nearly flavorless, highly resistant to going rancid, and capable of being produced in enormous volumes on relatively little land. Those properties alone would make it popular, but a regulatory earthquake in the early 2000s turned palm oil from a regional commodity into the world’s most consumed edible oil almost overnight.

The Trans Fat Ban That Changed Everything

For most of the twentieth century, food manufacturers relied on partially hydrogenated vegetable oils to get the firm, spreadable textures they needed in margarines, baked goods, and snack foods. Partial hydrogenation was cheap and effective, but it produced trans fatty acids, which turned out to be far worse for cardiovascular health than anyone had anticipated. When regulators around the world began restricting or banning trans fats, the food industry faced an enormous reformulation problem: what do you replace them with?

There were essentially two practical paths. One was to switch to interesterified fats, a newer form of chemically modified oil. The other was to go back to a naturally semi-solid fat that needed no hydrogenation in the first place. Palm oil was the obvious candidate. It is naturally saturated enough to be solid or semi-solid at room temperature without any chemical hardening, it has no cholesterol, and by the time trans fat bans rolled out, global palm oil production had expanded to a scale that could actually meet demand.¹ That timing was not coincidental. The surge in palm oil plantations across Southeast Asia throughout the 1990s and 2000s created the supply capacity just as the demand side exploded.

The Physical Properties That Make It Hard to Replace

Most vegetable oils are liquid at room temperature. Olive oil, sunflower oil, soybean oil, and canola oil all pour freely out of a bottle. That is great for salad dressing, but terrible if you need a fat that holds a cookie together, gives frosting its structure, or keeps a chocolate bar from melting on the shelf. Palm oil’s natural composition, roughly split between saturated and unsaturated fatty acids, gives it a semi-solid consistency in temperate conditions without any processing. Manufacturers can refine it into different fractions to get exactly the melting point they need: a harder fraction for pastry lamination, a softer one called palm olein for frying.

That frying performance matters commercially. In industrial deep fryers, palm olein resists oxidation better than partially hydrogenated soybean oil, meaning it breaks down more slowly and can be used longer before replacement.² For a fast-food chain running thousands of fryers, longer oil life translates directly into lower costs.

Palm oil also plays a less obvious but critical role in confectionery. Pure cocoa butter is expensive and supply is unreliable, so chocolate manufacturers have long used fats that mimic cocoa butter’s melting and crystallization behavior. Palm oil fractions, sometimes blended with other tropical fats, serve as cocoa butter replacers in coatings, fillings, and compound chocolate.³ Researchers have also shown that blending palm oil mid-fraction with other seed fats can produce cocoa butter substitutes that perform well in confectionery applications.⁴ If you have ever eaten a candy bar that says “chocolatey coating” instead of “chocolate,” palm oil derivatives were almost certainly involved.

It Is Not Just in Your Food

About a third of global palm oil production goes into non-food products, which is why the ingredient (or its derivatives) appears on labels you would never associate with cooking. The fatty acid chains in palm oil and palm kernel oil are ideal raw materials for surfactants, the molecules that make soap lather, shampoo foam, and detergent cut through grease. These fatty acyl groups combine with other bio-based compounds like sugars and glycerol to produce surfactants used across cosmetics, personal care, pharmaceuticals, paints, and industrial cleaners.⁵

Palm oil derivatives also show up in lipstick (where they provide smooth texture), toothpaste (as an emulsifier), and candles (as a wax substitute). In many of these products, the palm-derived ingredient has been processed so extensively that it bears no resemblance to the reddish crude oil that comes from the fruit. Ingredient lists may show names like sodium lauryl sulfate, cetyl alcohol, or stearic acid, all of which can be derived from palm.

Beyond consumer goods, palm oil has become a significant energy feedstock. Indonesia, the world’s largest producer, has promoted biodiesel blending as national policy, mandating that diesel fuel contain a growing percentage of palm-based biodiesel. The country’s B20 mandate, requiring 20 percent biodiesel blending, was designed to reduce fossil fuel imports while supporting the domestic palm industry.⁶ Indonesia has since pushed toward even higher blending ratios. The European Union, meanwhile, has been moving in the opposite direction, phasing out palm-based biofuel due to deforestation concerns. That policy tension is a good indicator of how politically charged this single crop has become.

The Yield Advantage

One of the most overlooked reasons palm oil dominates is sheer agricultural productivity. The oil palm tree produces far more oil per hectare than any competing oilseed crop. Soybean, sunflower, and rapeseed all need substantially more land to produce the same volume of oil. That yield gap is enormous, typically estimated at four to ten times the output per hectare depending on the comparison crop and growing conditions. This means that even though palm plantations are controversial for their environmental impact, replacing palm oil with another vegetable oil would require dramatically more farmland.

A 2023 modeling study made this point starkly: replacing palm oil with other vegetable oils would lead to an estimated increase in global deforestation of roughly 28 to 52 million hectares, while greenhouse gas emissions would remain roughly the same across all scenarios.⁷ Separate research reached a similar conclusion, finding that total replacement of palm oil could result in even greater adverse environmental consequences because alternative crops need more land.⁸ This does not mean palm oil production is environmentally benign. It means the problem is not palm oil per se but rather how and where it is grown.

The Environmental Costs Are Real

The expansion of oil palm plantations, concentrated in Indonesia and Malaysia, has been one of the major drivers of tropical deforestation over the past three decades. Natural forests, including biologically rich lowland rainforest, have been cleared to make way for monoculture plantations. Replacing these forests with palm eliminates plant diversity and the many animal species that depend on intact forest habitat.⁹ Orangutans, tigers, and elephants have become the recognizable faces of this crisis, but the broader biodiversity loss extends across thousands of less charismatic species.

Particularly damaging has been the conversion of tropical peatlands. Peat soils store enormous quantities of carbon, and when they are drained for plantations, that carbon oxidizes and escapes into the atmosphere for years. Remote sensing analysis of Peninsular Malaysia, Sumatra, and Borneo found that conversion of peatland to oil palm contributed to the loss of roughly 140 million metric tons of aboveground biomass carbon, along with annual emissions of about 4.6 million metric tons of belowground carbon from peat oxidation.¹⁰ Draining peat also makes the land prone to fires, which periodically blanket Southeast Asia in choking haze.

The industry’s response has included voluntary sustainability schemes, most prominently the Roundtable on Sustainable Palm Oil (RSPO), which certifies plantations that meet certain environmental and social standards. But assessments of the RSPO have highlighted both strengths and weaknesses. The standard-setting process has struggled to keep pace with rising global demand, and the effectiveness of sustainability standards remains questionable when market growth continues to outstrip certified supply.¹¹ Major corporations throughout the supply chain have adopted “No Deforestation, No Peat, No Exploitation” pledges, with an estimated 96 percent of global palm oil production covered by some form of no-deforestation commitment.¹² That coverage sounds reassuring, but the same research found that supply chain complexity makes these commitments difficult to implement and verify in practice.

What About the Health Concerns?

Palm oil’s saturated fat content, roughly half its fatty acid profile, has made it a target for nutritional criticism. The main saturated fat in palm oil is palmitic acid, and the default assumption has been that a high-palmitic-acid oil should raise cholesterol and increase heart disease risk. The picture from actual clinical research is more mixed than that assumption suggests.

A review in the World Journal of Cardiology concluded that many scientific studies, in both animals and humans, show that palm oil consumption does not raise serum cholesterol levels to the degree expected and that palm oil is not atherogenic (meaning it does not promote plaque buildup in arteries).¹³ However, a systematic review and meta-analysis of clinical trials found a more nuanced result: compared to vegetable oils low in saturated fat, palm oil raised total cholesterol and LDL cholesterol, though it also raised HDL cholesterol slightly and had no significant effect on triglycerides.¹⁴ The takeaway is that palm oil is not as harmful as the old partially hydrogenated oils it replaced, but it is not a health food either. Compared to oils rich in unsaturated fats like olive or canola, it does nudge blood lipids in the wrong direction.

A separate concern involves processing contaminants. When palm oil is refined at high temperatures, it can form compounds called chloropropanols, specifically 3-MCPD, which are classified as potentially harmful food contaminants.¹⁵ The European Food Safety Authority flagged these contaminants in 2016, and refiners have since invested in mitigation strategies to reduce 3-MCPD levels. This is a processing issue rather than something inherent to the oil itself, and it applies mainly to heavily refined palm oil used in infant formula and other sensitive products.

Smallholders and the Economics of Production

Conversations about palm oil tend to focus on large industrial plantations, but a substantial share of production comes from smallholder farmers, particularly in Indonesia. These smallholders manage their own plots, typically a few hectares, and palm oil has been a genuine engine of rural economic development and poverty reduction in regions with few other cash-crop options.¹⁶

The complications are real, though. Smallholders tend to have lower productivity per hectare than industrial estates and are associated with disproportionately higher rates of illegal land clearing, in part because they lack the capital and technical knowledge to farm sustainably. Certification programs designed for large companies are often too expensive and bureaucratically complex for a farmer with five hectares to navigate. Research on Indonesian smallholders has found wide variation in livelihood resilience: some, particularly migrants who received government support through Indonesia’s transmigration program, are relatively adaptive, while others, especially local farmers who established plantations independently, are considerably more vulnerable to market shocks and regulatory changes.¹⁷ Any serious effort to reform the palm oil industry has to grapple with the fact that millions of families depend on it for their livelihoods.

Could Anything Actually Replace It?

Given the environmental and social costs, a reasonable question is whether we could just stop using palm oil. The short answer is that substitution at scale creates its own set of problems, as the deforestation modeling mentioned earlier illustrates. But the longer answer involves emerging technologies that might eventually reduce demand without requiring more cropland at all.

Precision fermentation, using engineered microorganisms like yeast to produce specific fats in industrial bioreactors, is one of the more promising avenues. Researchers are working on tuning the metabolism of organisms like the yeast Yarrowia lipolytica to synthesize lipid fractions that could substitute for palm oil in high-value applications such as confectionery coatings and cosmetic ingredients.¹⁸ Advanced metabolic engineering and the use of low-cost feedstocks are helping close the price gap with traditional palm oil, though fermentation-derived fats remain significantly more expensive for bulk applications. These approaches are more likely to chip away at premium market segments first, think specialty chocolates and high-end skincare, before they could compete in the commodity frying-oil market.

Other researchers are exploring algae-based oils, waste-fat upgrading, and even gene-edited oilseed crops that could produce palm-like fat profiles in temperate climates. None of these are close to displacing palm oil at the roughly 80 million metric tons the world currently consumes each year, but they represent the beginning of a diversification that could eventually take pressure off tropical forests.

Reading the Label

If you have ever tried to avoid palm oil, you know how disorienting the ingredient list can be. Palm oil rarely appears under its own name outside of cooking oils. In processed foods, it may be listed as palm kernel oil, palm fruit oil, palmitate, palmate, or simply “vegetable oil” (a deliberately vague term that in many regions can legally refer to palm). In cosmetics and cleaning products, palm derivatives hide behind chemical names: sodium laureth sulfate, glyceryl stearate, cetearyl alcohol, stearic acid. One estimate suggests there are over 200 ingredient names that can indicate a palm-derived component.

Certification labels like RSPO-certified or Green Palm offer some traceability, but the supply chain is complicated. Palm oil from certified and uncertified plantations often passes through the same mills and refineries, making full segregation difficult and expensive. The “mass balance” model used by some certifiers allows mixing of certified and uncertified oil, with the producer buying credits equivalent to the certified volume. It is better than nothing, and it channels money toward more sustainable producers, but a consumer looking at an RSPO label should know it does not guarantee the physical oil in their product came from a deforestation-free plantation.

For people who want to reduce their palm oil footprint without driving up demand for alternatives that may require even more land, the most effective consumer strategy is simply eating fewer highly processed foods. The vast majority of palm oil in a typical Western diet enters through packaged snacks, instant noodles, frozen meals, baked goods, and confectionery. Cooking with whole ingredients and less-processed oils sidesteps the issue more effectively than trying to decode every ingredient list. That said, the realistic lever for systemic change is not individual shopping decisions but policy and corporate sourcing standards that push production toward already-degraded land and away from intact forest and peatland.
