US researchers say there needs to be a better understanding and regulation of foods offered at grocery stores. The team developed a publicly available database on the availability of processed foods at three large retailers to inform and empower consumers and policymakers.The GroceryDB database ranks 50,000 processed foods from Target, Whole Foods and Walmart stores based on ingredient lists, nutrition facts and prices. The results are available on the TrueFood website, where consumers can compare foods. For each food, the database includes a processing score, nutrition facts and an ingredient tree that shows its makeup.
