McDonald's tweaks recipes: real butter now, not margarine, in its McMuffins

Oak Brook, Illinois

MCDONALD'S has long shied away from talking about how it makes the food on its menu and what is in that food. The company is now being open and loud about it.

At an event on Monday at its HQ here, McDonald's announced several changes to its ingredients, including eliminating artificial preservatives from some breakfast foods and Chicken McNuggets, its most popular food item, and removing high-fructose corn syrup (HFCS) from its buns.
