From these objectives, the committee developed research goals, specifically to examine literature relevant to: • Food package regulation and the regulatory environment, including federal agency jurisdiction over animal based food products; • The context for consumers' use of nutrition information and product choices; • Consumer understanding and use of front-of-package (FOP) labeling systems, point-of-purchase labeling, and shelf tags; • Impact of the FOP labeling environment, including package design, package clutter, and product claims on consumer food choice and behavior; • Design models of FOP symbol systems and influences of symbol systems on consumer food choice and behavior; • Nutrients to limit and nutrient thresholds consistent with current dietary guidance; and • FOP educational and promotional health campaigns.
