Despite viral claims, In-N-Out has not switched to using beef tallow for its fries. The confusion began when a satirical April Fools’ post by a fan account was mistakenly cited in an official White House release praising companies for healthier food choices. In reality, In-N-Out still uses 100% sunflower oil for frying and has no current plans to switch to beef tallow, though the company says it is researching higher-quality oil options. The fast-food chain has made some real changes, like removing artificial dyes and using ketchup with real sugar, but the beef tallow rumor was simply a case of misinformation gone mainstream.
