Why the frying oil matters
Most fast-food chains fry in seed oils like soybean, canola, corn, or a blend of them, which are high in polyunsaturated fat (PUFA). A handful still use beef tallow or other stable fats, which are far lower in PUFA. The oil a kitchen fries in is the single biggest driver of how much seed oil ends up on your plate.
