McDonald's Ditches Beef Tallow

In 1990, McDonald's ditched beef tallow in their fries after millionaire Phil Sokolof-who survived a heart attack-spent $3 million on full-page newspaper ads blasting them for using unhealthy fats. The switch to vegetable oil was meant to be healthier, but fans hated the new taste. McDonald's ended up adding "natural beef flavoring" just to win them back.
