                                In 1990, under intense public pressure over health concerns, McDonald's officially switched from beef tallow to vegetable oil for cooking its fries. However, this change in cooking fat led to a significant shift in the fries' beloved flavor, a move that prompted the company to add a 'natural beef flavor' to compensate.
