Palm oil

What is palm oil?

Palm oil is the edible oil pressed from the fruit of the African oil palm, Elaeis guineensis. It is semi-solid at room temperature, roughly 50% saturated fat (mostly palmitic acid), 40% monounsaturated (oleic acid), and 10% polyunsaturated (linoleic acid). Palm kernel oil — from the seed rather than the fruit — is a distinct product, higher in saturated fat (~82%).

Palm oil is now the most-consumed vegetable oil globally, ahead of soybean, rapeseed, and sunflower. Roughly 85% of world production comes from Indonesia and Malaysia. Its dominance in industrial baking dates to the 2003 Danish trans-fat ban, which created an urgent need for a semi-solid, cheap, trans-fat-free replacement.

Where you find it

• Industrial baked goods — biscuits, croissants, doughnuts, cakes.
• Chocolate spreads and confectionery — including Nutella, most commercial chocolate.
• Instant noodles and ramen fried packets.
• Margarines and spreads.
• Frozen ready meals and pastry cases.
• Ice cream (for structural fat).
• Non-food uses — soap, cosmetics, biodiesel — outside this article's scope.

On ingredient lists it appears as "palm oil", "palm fat", "palm olein", "palm stearin", "hydrogenated palm oil", "palm kernel oil", "vegetable oil (palm)", or under one of ~200 derivative names (glyceryl palmitate, sodium palmitate).

Health evidence

The evidence on palm oil is nuanced:

• Compared to trans fats: substantially safer. Replacing trans fats with palm oil reduces cardiovascular risk.
• Compared to butter or coconut oil: roughly equivalent on lipid profile.
• Compared to unsaturated oils (olive, rapeseed, sunflower): palm oil raises LDL cholesterol. The Cochrane 2020 review estimated an approximate 0.24 mmol/L LDL increase when saturated fat replaces polyunsaturated fat at 5% of energy.

The WHO 2023 guideline on saturated fatty acid intake recommends keeping saturated fat below 10% of daily energy — for an adult on 2,000 kcal, roughly 22 g/day. A single palm-oil-heavy pastry can account for a third of that limit.

Environmental context

Palm oil cultivation is the largest single driver of tropical rainforest loss in Southeast Asia over the past three decades. The 2022 Curtis et al. analysis in Global Environmental Change attributed roughly 5% of global tropical deforestation to palm oil directly. RSPO certification exists but covers a minority of production. NakedCalorie surfaces palm-oil presence but does not currently distinguish RSPO-certified from conventional.

How NakedCalorie flags palm oil

Palm oil is a Tier 2 marker in the ingredient encyclopedia — a NOVA Group 4 signal when combined with industrial reformulation context, and always surfaced with the saturated-fat contribution per serving. See hydrogenated oils for the trans-fat context, seed oils for the alternative debate, and the scoring methodology for how it feeds the final score.
