By the end of fiscal 2018, Campbell Soup Co. will make all of its North American products without artificial colors or flavors.

Campbell is removing the ingredients as part of an effort to be more open with consumers, Chief Executive Officer Denise Morrison said.

“We’re talking, thinking and acting differently about the food we make,” Morrison said. “We will be more honest about what goes in our food, how we made our food.”

Campbell, based in Camden, NJ, is joining a series of food companies to make the move. Nestle USA plans to remove all artificial colors and flavors from its chocolate candy by the end of 2015. General Mills Inc. has made a similar pledge for its cereals.

Trying to rekindle growth after years of declining demand for its soup, Campbell is cutting $200 million in costs over three years and renewing its focus on emerging markets.

Campbell shares gained 1.8 percent to $48.32 at the close in New York. The stock has climbed 9.8 percent this year.
