Palm oil is not generally better than standard vegetable oils like soybean, canola, or sunflower oil when it comes to heart health. It contains significantly more saturated fat, which raises LDL (“bad”) cholesterol. But the full picture is more nuanced: palm oil has real advantages in cooking stability, shelf life, and even micronutrient content in its unrefined form. Which oil is “better” depends on what you’re using it for and how much of it you eat.
How They Differ in Fat Composition
The core difference between palm oil and most vegetable oils comes down to their fatty acid profiles. Palm oil is roughly 50% saturated fat, with palmitic acid as its dominant fatty acid. That puts it in a middle ground between butter (about 63% saturated) and oils like canola or soybean (which sit around 7% to 15% saturated). The rest of palm oil is mostly monounsaturated fat, with a small amount of polyunsaturated fat.
Common vegetable oils, whether soybean, sunflower, canola, or corn, are dominated by unsaturated fats. Canola oil is roughly 62% monounsaturated and 32% polyunsaturated. Soybean oil is about 61% polyunsaturated. These unsaturated fats behave differently in your body than the saturated fat concentrated in palm oil, and the health implications are measurable.
The Cholesterol and Heart Health Question
A meta-analysis of clinical trials published in the Journal of Nutrition found that palm oil raised LDL cholesterol by about 0.24 mmol/L compared to vegetable oils low in saturated fat. In the higher-quality randomized trials, the increase was even larger: 0.31 mmol/L. That’s a meaningful shift, roughly equivalent to what you’d predict based on palm oil’s saturated fat content alone.
Palm oil did slightly raise HDL (“good”) cholesterol compared to low-saturated-fat oils, but only by 0.02 mmol/L, a negligible bump. It performed better when compared to oils containing trans fats, raising HDL by 0.09 mmol/L. But since most countries have largely phased out trans fats, that comparison matters less than it used to.
At the cellular level, the difference makes sense. Palmitic acid, the main saturated fat in palm oil, and oleic acid, the main monounsaturated fat in oils like canola and olive, follow different metabolic pathways in muscle cells. Palmitic acid is associated with reduced insulin sensitivity, while oleic acid is not. Research on human muscle cells found that palmitic acid had a lower rate of fat breakdown and altered gene activity in ways linked to metabolic dysfunction. U.S. dietary guidelines have consistently recommended keeping saturated fat below 10% of total calories, a threshold that’s easier to exceed when palm oil is a regular part of your diet.
Where Palm Oil Has an Edge: Cooking Performance
If your priority is high-heat cooking or deep frying, palm oil holds up better than most vegetable oils. Refined, fractionated palm oil has a smoke point of about 235°C (455°F), compared to roughly 220°C (428°F) for a typical refined vegetable oil blend. That 15-degree difference matters in commercial frying and can mean less breakdown of the oil into harmful compounds at sustained high temperatures.
Palm oil is also naturally semi-solid at room temperature, which gives it functional properties that liquid vegetable oils can’t replicate without processing. After the food industry moved away from partially hydrogenated oils (the main source of artificial trans fats), palm oil became a go-to replacement in products like cookies, crackers, pastries, and margarine. The harder fraction of palm oil, called stearine, mimics the texture and mouthfeel that trans fats once provided. One trade-off: palm oil crystallizes slowly, which can cause products to become harder over time during storage.
Unrefined Palm Oil Has Unique Nutrients
Not all palm oil is the same. Unrefined “red” palm oil retains significant concentrations of compounds that are stripped out during standard refining. Crude palm oil contains between 400 and 3,500 ppm of carotenoids, the same orange-red pigments found in carrots and sweet potatoes that your body converts into vitamin A. Red palm olein, even after partial refining, retains around 534 ppm of carotenoids. Standard yellow palm oil, which undergoes full bleaching and deodorizing, loses these entirely.
Palm oil is also one of the richest natural sources of tocotrienols, a form of vitamin E that acts as a potent antioxidant. Total vitamin E content in palm oil ranges from 600 to 1,000 ppm, with tocotrienols making up 72% to 80% of that total. Red palm olein contains even higher concentrations, around 1,260 ppm total. Most common vegetable oils contain tocopherols (the other form of vitamin E) but far fewer tocotrienols.
These micronutrient advantages apply specifically to unrefined or minimally refined red palm oil. The refined palm oil found in packaged foods and most grocery stores has been stripped of its carotenoids and much of its vitamin E content, leaving behind the fat profile without the nutritional bonuses.
Land Use and Environmental Cost
Oil palm trees produce far more oil per hectare than any competing crop. A hectare of oil palm yields roughly 3,000 to 4,000 kilograms of oil per year, while soybean yields around 400 to 600 kilograms per hectare, and rapeseed (canola) falls somewhere in between at roughly 1,000 to 1,500 kilograms. This efficiency means that replacing palm oil with other vegetable oils would require dramatically more farmland to produce the same volume of oil.
That efficiency creates a paradox. Palm oil requires less land per ton of oil, but its high profitability has driven massive deforestation in Southeast Asia, particularly in Indonesia and Malaysia. Choosing between palm oil and other vegetable oils on environmental grounds isn’t straightforward. If you want to reduce your environmental footprint, certified sustainable palm oil (look for the RSPO label) is one option, though the certification system has its critics.
Which One Should You Cook With?
For everyday cooking at moderate temperatures, sautéing vegetables, making dressings, or light pan-frying, standard vegetable oils like canola, soybean, or sunflower are the better choice for heart health. They’re lower in saturated fat, and the evidence on LDL cholesterol is consistent enough to take seriously.
Palm oil makes more sense in specific situations: high-temperature frying where stability matters, baking where you need a solid fat, or when you’re using unrefined red palm oil for its carotenoid and vitamin E content. In West African and Southeast Asian cuisines, red palm oil is a traditional cooking fat with genuine nutritional value that a bottle of canola oil can’t replicate.
The dose matters more than the choice of oil in isolation. Using palm oil occasionally in cooking or eating packaged foods that contain it is unlikely to meaningfully change your cholesterol levels. Making it your primary cooking fat, especially the refined version, shifts your saturated fat intake in a direction that most nutrition evidence suggests you’d want to avoid.
