Food Purchases, Intakes, and Dietary Quality

As knowledge of the relationship between diet and long-term health has grown, so have concerns about hunger and food insecurity; overweight and obesity; and dietary knowledge, attitudes, and behavior. Mathematica collects the data needed to address these issues, including dietary intake data for national samples of infants, toddlers, and young preschoolers; school-age children; older adults; and SNAP households.  We are a leader in collecting, coding, and analyzing nutrition-related data using state-of-the-art methods.
