McDonald's is on a mission to eliminate artificial ingredients from its menu. 

The fast-food company, which hopes to attract more health-conscious consumers to its drive-thrus and counters, announced changes to its most popular hamburgers Wednesday.

“We know quality choices are important to our customers. From switching to 100 percent fresh beef in our quarter-pound burgers, cooked right when ordered in a majority of our restaurants, to removing artificial preservatives in our Chicken McNuggets, we’ve made significant strides in evolving the quality of our food—and this latest positive change to our classic burgers is an exciting part of that story," said Chris Kempczinski, McDonald’s USA President. "This development demonstrates our commitment to leading with the customer and building a better McDonald’s.”
