FIGURE 1

Expansion of food systems data sources to include global databases. This diagram is a general overview. Using FoodData Central as a starting point [12], arrows indicate connections to different types of data needed for food systems research. This type of mapping visualization provides an overview of data sources grouped by category, all of which are important components in food data systems, rather than identifying specific connections between data sources. The color indicates groups of data that are siloed together. Groups are not intended to be all encompassing, and data sources within each group often overlap. Abbreviations: EPA, Environmental Protection Agency; ERS, Economic Research Service; FDA, United States Food and Drug Administration; FNDDS, Food and Nutrient Database for Dietary Studies; FPED, Food Patterns Equivalents Database; GDP, Gross Domestic Product; GHG, greenhouse gas; HEI, Healthy Eating Index.
