The Science Behind Shelf Guide
Our extensive product analysis saves you time reading labels.
We evaluated thousands of products to categorize them with our Shelf Guide icons. Many of the items we carry earned more than one attribute! Our Registered Dietitian, Yvette Waters, MS, RDN, CISSN, worked closely with researchers to learn what is essential to our customers searching our shelves and developed a new set of icons.
Waters determined the categories and icons, then created definitions for each and worked with our data partner to decide which products get which attributes.
Ingredient Analysis
In some cases, we more closely analyzed product ingredients and Nutrition Facts to categorize products with the correct Shelf Guide definition.
Certifications and Packaging Claims
We based many of our Shelf Guide definitions on whether a product has a third-party certification or packaging claim. For example, Organic, Sustainable or Non-GMO.
