Scotland:Borders farmers take on Tuscany
Every few years a northern rapeseed oil is launched to ‘take on Tuscany’. It is a fair fight in some ways and a mismatch in others. Both are good oils; they are simply good at different things, and the sales pitch tends to blur that.
Cold-pressed rapeseed oil — canola, to North Americans — has become a genuine culinary product in northern Europe, golden, nutty, locally grown and cheaper than olive oil. Its marketing loves a David-and-Goliath story against Mediterranean olive oil, usually leaning on omega-3 content and food miles. Some of that is true and useful; some is spin. It is worth laying the two side by side without tribal loyalty, because the honest answer is that a good kitchen has room for both.
| Cold-pressed rapeseed | Extra virgin olive oil | |
|---|---|---|
| Main fat | Monounsaturated, with more polyunsaturated | Monounsaturated (oleic), lower polyunsaturated |
| Omega-3 (ALA) | Notably higher | Low |
| Saturated fat | Lower | Low, a little higher than rapeseed |
| Polyphenols | Few | Many (in fresh extra virgin) — the antioxidants |
| Smoke point | Higher — suits high heat | Fine for normal cooking; best raw |
| Flavour | Mild, nutty | Distinct — varies by variety and origin |
| Provenance | Can be very local (UK/N. Europe) | Mediterranean, long tradition |
Where rapeseed genuinely wins
Rapeseed oil has real advantages, and it is fair to name them. It carries more of the omega-3 fat ALA and less saturated fat than olive oil, it has a higher smoke point that suits searing and roasting, it is cheaper, and in Britain or northern Europe it can be grown a few counties away rather than shipped across a continent. For hot cooking and everyday frying, a good cold-pressed rapeseed oil is an entirely sensible, and often local, choice.
Where the marketing overreaches
Now the spin. The favourite line — that rapeseed has ‘ten times the omega-3’ of olive oil — is technically true and largely beside the point, because olive oil was never valued for omega-3 in the first place. Olive oil’s health interest rests on its monounsaturated fat and, above all, its polyphenols, the antioxidant compounds rapeseed largely lacks. Comparing the two on omega-3 alone is like ranking cheeses by their vitamin C. Each oil should be judged on what it is actually for.
The thing olive oil has that rapeseed does not
Flavour and polyphenols are olive oil’s trump cards. A fine extra virgin tastes of a place — a variety, a hillside, a harvest — and carries bitter, peppery antioxidants you can literally taste and that underpin its health reputation. Cold-pressed rapeseed is pleasant and nutty, but it does not have that range or that chemistry. So the honest division of labour is simple: reach for rapeseed for high-heat, everyday, budget and local cooking; reach for a good olive oil when you want flavour and a raw finish. Not a war — a kitchen with two drawers.
Practical takeaways
- Use rapeseed for high heat, frying and roasting, and when you want a local, cheaper oil.
- Use olive oil for flavour and raw finishing, where its polyphenols and taste show.
- Ignore the ’10x omega-3′ pitch — olive oil was never about omega-3.
- Keep both; they solve different problems rather than competing.
Rapeseed vs olive oil: common questions
Is rapeseed oil healthier than olive oil?
Neither is simply ‘healthier’. Rapeseed has more omega-3 and less saturated fat; olive oil has polyphenols and flavour. They suit different jobs.
Does rapeseed oil really have more omega-3?
Yes, considerably — but olive oil was never valued for omega-3, so the comparison misses what olive oil is actually good for.
Which is better for frying?
Rapeseed, generally — its higher smoke point suits high heat, and it is cheaper for everyday cooking.
Which is better for salads and finishing?
A good extra virgin olive oil, whose flavour and polyphenols shine when it is used raw.
Should I switch from olive oil to rapeseed?
No need to choose. Many cooks use rapeseed for high-heat cooking and keep a good olive oil for flavour and finishing.
The ‘local oil takes on Tuscany’ story is good marketing and lazy nutrition. Cold-pressed rapeseed is a genuinely useful oil — more omega-3, higher smoke point, cheaper, often grown down the road — and for frying and everyday heat it is a smart, local choice. But the ‘ten times the omega-3’ boast is beside the point, because olive oil was never an omega-3 product; its whole case is monounsaturated fat, flavour and polyphenols, which rapeseed largely lacks. Keep both, use each for what it is good at, and ignore anyone selling it as a duel.
