USDA’s Economic Research Service (ERS) has developed a unique treasure trove of data from a survey on food purchases and acquisitions by U.S. households - USDA’s National Household Food Acquisition and Purchase Survey FoodAPS. To protect individual survey respondents’ privacy, access to the data had been restricted to researchers from academic institutions and government agencies. Now, a modified version that aggregates information so individuals cannot be identified, but still provides valuable data for research and planning is available to everyone.

What can FoodAPS data tell us? USDA’s investment in FoodAPS was undertaken to fill a critical knowledge gap and encourage research that can support an evidence-based approach to Federal food assistance policies and programs. The data are being used to address a range of questions such as where households acquire food in a typical week, which foods they acquire, how much they pay for the food and how the acquired foods match recommendations for a healthy diet.

What’s in the food we eat? Have you ever wondered if the foods past generations ate as children were more nutritious than the foods you now eat, or vice versa? Well, let’s take a look at the amount of nutrients available in foods for over 100 years!

The Nutrient Content of the U.S. Food Supply is a historical data series beginning with 1909, on the amounts of nutrients available in the food supply for consumption (not nutrients consumed), on a per capita per day basis, as well as percentage contributions of nutrients by major food groups. The series provides data for food calories and the calorie-yielding nutrients which are protein, carbohydrate, and fat (total, saturated, monounsaturated, polyunsaturated, and individual fatty acids); cholesterol; dietary fiber; 10 vitamins; and 9 minerals. Food supply nutrients are closely linked to food and nutrition policy, with prominence in areas related to nutrition monitoring, Federal dietary guidance, fortification policy, and food marketing strategies.
