Wendy's UK Seed Oil Report Card
Based on our menu research, Wendy's UK cooks with: rapeseed + sunflower blend — the UK ingredient statement for the fries reads "Vegetable Oils (Rapeseed, Sunflower) - in varying proportions" (plus rapeseed oil with dimethylpolysiloxane anti-foam), which is a very different fryer from the US soybean/canola/cottonseed blend; everything that goes through the fryers (natural-cut skin-on fries, Boneless Bites, Chicken Tenders, breaded chicken fillets, Halloumi Fries, Hash Brown Bites, Mini Doughnuts) carries that rapeseed/sunflower PUFA, and the Heinz mayo, ranch, Caesar dressing and dip pots are rapeseed-oil emulsions on top; the fresh-beef patties, bacon, cheese and Frostys are dairy/beef fat led and score much lower. UK portions are notably smaller than US ones (large fries 239 kcal / 11 g fat), so the fried scores land below the US equivalents. Across the 40 menu items we analyzed, it averages 6.2g estimated PUFA per item, earning a seed-oil grade of C (High Risk).

What are seed oils?
Seed oils — canola, soybean, sunflower, corn, and similar vegetable oils — are extracted from seeds using high heat and chemical solvents. They are very high in polyunsaturated fats (PUFAs), which are unstable at cooking temperatures and can oxidize easily. Many health-conscious eaters choose to minimize seed oils and prefer foods cooked in beef tallow, butter, coconut oil, or olive oil instead. This page shows estimated PUFA grams per menu item to help you make more informed choices. These are estimates — actual values vary by preparation and location. Curious why people avoid them?
