Build my orderHow Arby's has changed its frying oil
Arby's announced the change in late November 2006 and said in June 2007 that every US restaurant had made the switch. The frying oil went from partially hydrogenated to non hydrogenated corn oil, and its potato suppliers stopped using hydrogenated oil in the par fry step too. Source

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 Arby's report card, or where it lands on the Seed Oil Index. See which chains fry in real fats on Tallow Watch.
