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?
