At the same time, there are new challenges for diet, health, and food safety. Biotechnological innovations in food production have raised concerns among some consumers about the safety of some foods.

How does consumption of specific foods change after a food safety outbreak? Many different kinds of information are needed to address these questions and to formulate or adjust policy: information on food expenditures, food consumption, food prices, where food is purchased and consumed, food preparation, diet and health knowledge, and possible sources of contamination.

However, with existing data sources, actual consumption of this food can only be inferred on an aggregate level. The most timely data on food purchases and food consumption are collected by market research firms to assess trends in food consumption.

As part of this effort, ERS asked the Committee on National Statistics of the National Academies to convene a panel of experts to review data needs to support research and decision making for USDA food and nutrition policies and programs. The panel was also charged to assess the adequacy of the current data infrastructure and to recommend enhancements to improve it.

reviewed almost 100 data sources for their potential to support food assistance program outcomes research, identifying 13 data sources that are clearly useful, another 13 sources that could be useful if they were expanded in one or more ways, and 70 sources that are not useful because they are outdated, restricted to specific populations, lack sufficient content on program participation, nutrition, and health, or comprise administrative records that would be difficult to link to datasets with program participation information.

and will issue a final report that examines in depth the current food insecurity measure and possible alternatives to it. So as not to duplicate work, this report on improving data to analyze food and nutrition policies does not consider food insecurity measurement, although there is a brief discussion in Chapter 4 of the food insecurity scale and other food-related information in the Current Population Survey December supplement.

Food assistance programs include the Food Stamp Program, the National School Lunch and Breakfast Programs, the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) , and several smaller programs, including the Child and Adult Care Food Program, the Commodity Supplemental Food Program, the Emergency Food Assistance Program (TEFAP)

Finally, food safety policies, including federal and state regulations for food production and preparation, inspections, and surveillance of food-borne illness, affect the quality and variety of foods that reach the consumer. This overview makes it clear that a great deal of information is needed to fully understand food consumption decisions and their consequences for diet and health.

However, the Food Safety Survey, which was fielded in 1988, 1993, 1998, and 2001, does not include data on actual food consumption, its data on household characteristics are limited, and its response rates are low (61 percent in 2001 -- see www.cfsan. fda.gov/~lrd/ab-foodb.html [June 2005]

However, the FoodNet population information does not include questions about food preparation and storage or residents' knowledge of food safety issues, and information on household characteristics is limited (www.cdc.gov/foodnet/what_is.htm [June 2005]

The Total Diet Study began in 1961. It obtains samples of food purchased by FDA personnel in selected cities, which are then analyzed by FDA laboratories; the results are used to estimate exposures by weighting to food consumption patterns from the Continuing Survey of Food Intakes by Individuals (the CSFII food consumption data are now part of NHANES -- see Chapter 2)
