The 5 cleanest things to order at Fatburger
Learn this once: a salad with grilled protein and the dressing left off is nearly always the lowest seed oil order anywhere. So the list below sticks to real meals, salads included, never just a water.

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. See the full breakdown on the Fatburger report card, or where it lands on the Seed Oil Index.
