McDonald’s is rolling out a new version of the famous Chicken McNugget. The new recipe drops artificial preservatives in favor of more ingredients like rice starch and lemon juice. The restaurant has already been testing the new nuggets in parts of Oregon and Washington State. The current McNugget has more than 30 ingredients. The company says the new McNugget formula is something “parents can feel good about.” The plan is to start selling the new McNuggets nationwide ahead of this year’s Olympic Games in Rio de Janeiro.
