Denny's Canada Seed Oil Report Card
Based on our menu research, Denny's Canada cooks with: canola-based liquid frying oil in Canadian kitchens (the Canadian foodservice default), but Denny's own fry ingredient statements describe the vegetable oil as a blend that may include soybean, cottonseed and sunflower alongside canola, so fried items are scored on the higher end of the canola range (~35-40% of fryer fat as PUFA) rather than pure canola (~30%). Everything deep-fried shares one fryer: wavy-cut fries, seasoned fries, onion rings, tots, mozzarella sticks, chicken tenders and the battered fish. Griddle items (slams, pancakes, French toast, hash browns, eggs, bacon, sausage, burgers, steaks) are cooked on a buttered/oiled flat top and carry mostly animal and dairy fat, which is why they score much lower than the fryer items. Mayo- and ranch-dressed sandwiches and salads pick up extra PUFA from canola-based dressing rather than from the fryer. Canadian nutrition panel gives total fat and saturated fat only (no polyunsaturated line), so PUFA is apportioned from total fat minus saturated fat by cooking method.. Across the 40 menu items we analyzed, it averages 7.5g 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. New to the topic?
