Palm oil is one of the world’s most successful industrial ingredients: cheap, stable, long-lasting, heat-resistant and outrageously versatile. That’s why you’ll find it in everything from margarine and chocolate to shampoo, toothpaste, candles and biodiesel. But that success has a price — for our health and for the world’s forests, wildlife and climate. This piece pulls no punches: we need to ask why we still let a handful of companies and two countries (Indonesia and Malaysia) decide what ends up in our food and bathrooms — and why consumers with heart or metabolic disease should be alarmed.
Why manufacturers love palm oil (and why we keep seeing it on labels)
Palm oil ticks almost every box a manufacturer cares about:
- It’s cheap to produce and yields more oil per hectare than any other oil crop, so less land — and lower cost — for the same amount of oil.
- It has excellent oxidative stability and a high smoke point, so it gives long shelf life and is ideal for frying and processed foods without generating trans fats.
- It’s semi-solid at room temperature, so it can replace animal fats and hydrogenated oils in spreads, baked goods and confectionery while delivering the desired texture.
Those functional and financial reasons explain why food companies — and many non-food manufacturers — reached for palm oil en masse when trans fats became publicly unacceptable. But convenience and cost aren’t the same as safety or sustainability.
What palm oil does to your health — the hard facts
Palm oil is not a single, uniform ingredient. “Red” (unrefined) palm oil contains antioxidants and provitamin A, while refined palm oil loses many of those compounds and is mostly a mix of saturated and unsaturated fatty acids. The critical point for public health is this:
- Palm oil is relatively high in saturated fat, particularly palmitic acid. Diets high in saturated fats raise LDL (“bad”) cholesterol and are associated with increased cardiovascular disease risk when they replace polyunsaturated fats. Multiple reviews and meta-analyses show that replacing saturated fats with polyunsaturated fats lowers heart disease risk.
- Clinical and feeding studies looking specifically at palm oil find mixed results, but the weight of evidence indicates that substituting palm oil for unsaturated vegetable oils worsens lipid profiles (increases LDL) more than replacing with polyunsaturated oils. That’s relevant for people who already have coronary disease, stents, prior heart attacks, high LDL or diabetes — groups who are particularly sensitive to dietary saturated fat.
- There are other concerns with highly processed cooking fats: at high temperatures some refined oils can form harmful chemicals (e.g., glycidol derivatives), and ultra-processed foods containing palm oil often carry excess salt, sugar and refined carbs — all bad news for hearts.
Bottom line: occasional culinary use of red palm oil carries different nutritional implications than regular consumption of refined palm oil as a staple ingredient in processed foods. If you have heart disease, type 2 diabetes, or high LDL, it’s sensible to treat frequent intake of palm-oil-rich processed foods the same way you treat other saturated-fat loaded foods.
The environmental cost — not just trees, but climate and extinction
Palm oil’s footprint is not limited to local deforestation:
- Vast swathes of tropical rainforest and carbon-rich peatlands in Indonesia and Malaysia have been converted to oil-palm plantations. That destroys habitat for endangered species (orangutans, Sumatran tigers, many birds) and releases huge amounts of greenhouse gases — peatland clearance is a major source of CO₂ emissions.
- Even though oil palm is land-efficient per tonne of oil produced, much expansion has meant permanent loss of ancient forests and drained peat — which is a climate catastrophe. Replacing a hectare of peat forest with palms often releases decades to centuries of stored carbon in months. Earth.org
- The social costs are serious too: local communities lose forests and resources, smallholders can be exploited, and local biodiversity collapses as monocultures replace diverse ecosystems. World Wildlife Fund
So the environmental story isn’t “palm oil = always worse per litre” — it’s that the way palm oil has been expanded and farmed has caused outsized environmental damage.
Everyday products that commonly contain palm oil (read labels)
Palm oil and palm-kernel derivatives hide under many ingredient names. You’ll find them in:
Foods
- Margarine, spreads and baking fats
- Packaged biscuits, cakes and pastries
- Chocolate and confectionery
- Instant noodles and snack chips/crisps
- Ice cream and creamy fillings
- Ready meals and many processed savoury products
- Some margarines and low-cost butter replacements
Household & Personal care
- Soap, shampoo, shower gel and detergents
- Toothpaste, lipstick, moisturisers and cosmetics
- Laundry detergents, candles and some cleaning products
Other uses
- Some biofuels and industrial lubricants
Check labels for: “palm oil,” “palm kernel oil,” “palm stearin,” “sodium palmate,” “sodium palm kernelate,” “glyceryl,” “stearate” and many other derivatives — palm derivatives are widely used because they’re cheap and functional. Verywell Health
Better alternatives manufacturers can use — and the trade-offs
There is no perfect one-to-one swap that’s identical in price, performance and environmental footprint. But producers who want to cut saturated fat, improve nutrition, and reduce environmental harm can consider mixes and smarter sourcing.
Healthier oil alternatives (nutrition focus)
- High-oleic sunflower oil / high-oleic canola/rapeseed oil — lower in saturated fat, higher in monounsaturated fats; good for frying and shelf stability when fractionated or blended. These are healthier for heart disease risk compared with palm. BMJ
- Canola (rapeseed) oil — relatively neutral taste, low saturated fat and favourable lipid effects when used instead of palm. JACC
- Olive oil / avocado oil — heart-healthy monounsaturated fats, but higher cost and different functional properties (may not set the same way in margarine or confectionery). Best for dressings and low-temperature cooking. The Nutrition Source
Technical / functional substitutes for texture and stability
- Interesterified blends (blending fully hydrogenated oils with liquid oils to get semi-solid fats without trans fats) — these can replace palm in some applications, but technical expertise and regulatory testing are required.
- Cocoa butter / cocoa-butter equivalents — used in some confectionery to replicate structure, but costlier and taste/texture differences matter.
- Shea or illipe — used in specialty formulations (cost and supply limit use at scale).
Environmental and supply considerations
- Some alternatives (e.g., soybean) require more land per tonne of oil than palm — so wholesale substitution without care can increase deforestation elsewhere. Any reformulation plan must consider both nutritional and environmental trade-offs. Palm’s high yield is a reason it’s so widespread; the correct response is better farming and supply-chain accountability, not an automatic swap to another oil that causes greater land use.
A pragmatic producer roadmap
- Prioritise replacing refined palm oil in foods with high-oleic sunflower or rapeseed blends where feasible — lowers saturated fat.
- Reduce overall fat and reformulate recipes to rely less on semi-solid fats where possible (use emulsifiers, restructure recipes).
- Use certified sustainable palm (RSPO) only if palm cannot be removed — and push for transparent traceability to mills and plantations. Certification is imperfect but better than nothing when done properly.
- Invest in innovation — interesterification, enzymatic solutions and novel plant oils can replicate texture without the same saturated fat profile.
- Label clearly and communicate to consumers why changes are made — many shoppers will prefer lower-saturated-fat formulations and deforestation-free sourcing.
What consumers can do — practical and powerful steps
- Check labels. If the product lists palm derivatives and you have heart disease or high LDL, consider switching to alternatives with sunflower, rapeseed, olive or avocado oils.
- Eat fewer ultra-processed foods. Many palm-oil exposures come from packaged snacks, pastries and instant meals that are unhealthy for multiple reasons.
- Support companies that publish transparent supply chains and use RSPO-segregated or 100% traceable palm, or better still, no palm in their products.
- Push for policy change. Demand that governments and large buyers (retailers, catering services) require deforestation-free sourcing and healthier fat profiles.
Final reckoning: stop treating palm as a convenience, start treating it like a policy problem
Palm oil is a symptom of a global system that values cheap calories, long shelf life and low manufacturer costs over community health and planetary health. It’s not enough for companies to hide behind “efficiency” or “jobs” — the environmental cost (forest loss, peat emissions, species extinction) and the public health trade-offs (increased saturated fat in processed food) are real and measurable.
For those of us with heart disease, diabetes or metabolic risk, the message is clear: READ THE LABEL, minimise regular consumption of refined palm-oil-rich processed foods, choose products formulated with unsaturated oils where possible, and hold producers accountable for both the fat profile and the origin of the oils they use.
