NEW YORK (AP) — Panera says it will remove artificial colors, flavors, sweeteners and preservatives from its food by 2016, a reflection of the growing distaste people are showing for such ingredients.

The chain of bakery cafes, which has about 1,800 U.S. locations, is making the pledge as part of a “Food Policy” it is unveiling Tuesday that outlines its commitment to “clean” and “simple” ingredients.

The announcement comes at a time when Panera Bread Co. is facing slowing sales growth and working to jumpstart its business.

It also underscores how positioning foods as natural has become a marketing advantage, regardless of whether it brings any nutritional benefits.
