McDonald’s has announced it will remove a number of ingredients from its menu in the US as the fast food chain continues to adapt to changing consumer trends. The changes will affect about 50% of products on its US menus.

McDonald’s, which has more than 14,000 restaurants in the US, said it will remove artificial preservatives in a number of products including its chicken nuggets, sausages, eggs and breakfast sandwiches. McDonald’s also said it has stopped sourcing chickens raised on antibiotics also commonly used in humans from its supply chain and announced plans to stop using eggs from chickens raised in cages.
