As new research becomes available, an ingredient that might not have been considered problematic may now be an ingredient of concern or unacceptable.

Depending on the degree of concern, we will either immediately remove it from a sale, or we will 'grandmother in' the ingredient and allow products containing it to remain on the shelf while we encourage vendors to reformulate. Our underlying philosophy is that food should come from real sources and undergo as few modifications as possible. We work rigorously to keep our food as clean and as simple as we can.
