Food Choices and Dietary Quality

Mathematica is a leader in collecting, coding, and analyzing diet-related data using state-of-the-art methods. We assess the food and nutrient content of diets; household food purchases; and meals provided through nutrition assistance programs. We have assessed dietary intakes of infants, toddlers, and young preschoolers; school-age children; and older adults. We have examined the nutritional quality of foods purchased by SNAP households, as well as the nutritional quality of meals and snacks served in schools and congregate and home-delivered meals for older adults.
