Butter vs Margarine / Spreads

Side-by-side comparison, when-to-use-each guide, and instant conversion. Reviewed for 2026.

Quick answer: Butter: ~80% saturated fat, natural, flavour. Traditional margarines: partially hydrogenated vegetable oils (trans fats) — now banned in UK. Modern spreads: mostly unsaturated vegetable oils (sunflower, olive), often lower saturated fat, not suitable for all baking. UK regulations banned trans fats in margarines in 2020.

Frequently asked

?

Is butter worse for your heart than margarine?

The evidence has shifted. Trans fat margarines were worse than butter. Modern spreads (sunflower, olive) have better saturated fat profiles than butter. The UK diet debate has moved on — current NHS guidance focuses on overall dietary pattern rather than butter vs spread, and both fit a healthy diet in moderation.

?

Can I substitute spread for butter in baking?

Only if the label says 'suitable for baking'. Spreads with high water content (>50%) don't behave like butter in cakes and pastry — cakes can be dense or collapse. Block-style baking spread (e.g. Stork blocks) works for most baking. Soft tub spreads generally don't.
