  • Fruit and Vegetable Consumption by Low-Income Americans: Would a Price Reduction Make a Difference?

    ERR-70, January 09, 2009

    ERS study found that a 10-percent reduction in prices would encourage low-income Americans to raise consumption of fruit by 2.1-5.2 percent and vegetables by 2.1-4.9 percent.

  • On the Accuracy of Nielsen Homescan Data

    ERR-69, December 30, 2008

    Researchers use Nielsen Homescan data, which provide detailed food-purchase information from a panel of U.S. households, to address a variety of important research topics. However, some question the credibility of the data since the data are self-recorded and the recording process is time-consuming. Matching purchase records from 2004 Homescan data with data obtained from a large grocery retailer, it is evident that quantities purchased are reported more accurately in Homescan than are prices. Many of the price differences may be driven by the way Nielsen imputes prices: when available, Nielsen uses store-level prices instead of the actual price paid by the household. There are also differences by household type in the tendency to make mistakes that are correlated with demographic variables. However, the fraction of variance explained by the documented recording errors is in line with other research data sets for which cross-validation studies have been conducted.

  • Food Safety and Imports: An Analysis of FDA Import Refusal Reports

    EIB-39, September 09, 2008

    This report examines U.S. Food and Drug Administration (FDA) data on refusals of food offered for importation into the United States from 1998 to 2004. Although the data do not necessarily reflect the distribution of risk in foods, the study found that import refusals highlight food safety problems that appear to recur in trade and where the FDA has focused its import alerts, examinations (e.g., sampling), and other monitoring efforts. The data show some food industries and types of violations may be consistent sources of problems both over time and in comparison with previous studies of more limited data. The three food industry groups with the most violations were vegetables (20.6 percent of total violations), fishery and seafood (20.1 percent), and fruits (11.7 percent). Violations observed over the entire time period include sanitary issues in seafood and fruit products, pesticides in vegetables, and unregistered processes for canned food products in all three industries.

  • Is Dietary Knowledge Enough? Hunger, Stress, and Other Roadblocks to Healthy Eating

  • The National School Lunch Program Background, Trends, and Issues

    ERR-61, July 18, 2008

    The National School Lunch Program (NSLP) is the Nation's second largest food and nutrition assistance program. In 2006, it operated in over 101,000 public and nonprofit private schools and provided over 28 million low-cost or free lunches to children on a typical school day at a Federal cost of $8 billion for the year. This report provides background information on the NSLP, including historical trends and participant characteristics. It also addresses steps being taken to meet challenges facing administrators of the program, including tradeoffs between nutritional quality of foods served, costs, and participation, as well as between program access and program integrity.

  • Food Security Assessment, 2007

    GFA-19, July 03, 2008

    The number of food insecure people in the 70 lower income countries covered in this report rose between 2006 and 2007, from 849 million to 982 million. Food insecure people are those consuming less than the nutritional target of 2,100 calories per day. The food security situation of these countries is projected to deteriorate over the next decade. The distribution gap-an indicator of food access-is projected to rise from 44 million tons in 2007 to more than 57 million tons in 2017. This is more than seven times the amount of food aid received by these countries in 2006. Sub-Saharan Africa, already the most vulnerable region with the lowest calorie intake levels, will suffer the greatest deterioration in food security.

  • Dietary Assessment of Major Trends in U.S. Food Consumption, 1970-2005

    EIB-33, March 28, 2008

  • Can Food Stamps Do More To Improve Food Choices? An Economic Perspective

    EIB-29, September 27, 2007

    Eight economic information bulletins compile evidence to address the question of whether the Food Stamp Program could do more to encourage healthful food choices.

  • Can Food Stamps Do More to Improve Food Choices? An Economic Perspective-Making Healthy Food Choices Easier: Ideas From Behavioral Economics

    EIB-29-7, September 27, 2007

    With obesity the most prevalent nutrition problem facing Americans at all economic levels, promoting diets that provide adequate nutrition without too many calories has become an important objective for the Food Stamp Program. Findings from behavioral economics suggest innovative, low-cost ways to improve the diet quality of food stamp participants without restricting their freedom of choice. Unlike more traditional economic interventions, such as changing prices or banning specific foods, the strategies explored in this brief can be targeted to those participants who want help making more healthful food choices.

  • Can Food Stamps Do More to Improve Food Choices? An Economic Perspective—Nutrition Information: Can It Improve the Diets of Low-Income Households?

    EIB-29-6, September 03, 2007

    The Food Stamp Nutrition Education (FSNE) component of the Food Stamp Program is intended to improve the food choices, diet quality, and health of program participants. This brief discusses the FSNE program, how it operates, and how it has grown over time. The brief also considers the challenges of nutrition education in general and discusses the research and evaluation needs suggested by the findings.

  • Food Security Assessment, 2006

    GFA-18, June 28, 2007

    The number of hungry people in the 70 lower income countries covered in this report rose between 2005 and 2006, from 804 million to 849 million. However, the food distribution gap-an indicator of food access-declined, which means that, although more people are vulnerable to food insecurity, the intensity was less in 2006 than in 2005. By 2016, the number of hungry people is projected to decline in all regions, except Sub-Saharan Africa. The average nutrition gap, the indicator of food availability, was 13.5 million tons (grain equivalent) in 2006 and is expected to increase to 14 million tons by 2016. Sub-Saharan Africa accounts for 85 percent of this gap, the low-income countries of Asia for only 14 percent, and the low-income countries of Latin America and the Caribbean for the remaining 1 percent. The average nutrition gap was much smaller than the distribution gap, which takes into account unequal purchasing power within countries. The distribution gap was an estimated 27 million tons in 2006 for all 70 countries, decreasing to close to 26 million tons by 2016.

  • Could Behavioral Economics Help Improve Diet Quality for Nutrition Assistance Program Participants?

    ERR-43, June 01, 2007

  • Vegetables and Melons Outlook: March 2007

    VGS-31901, March 06, 2007

    Carrots are one of the most popular vegetables in the United States and fresh-market carrot consumption has been increasing over the past few decades. Using a combination of ACNielsen Homescan panel data and USDA's Continuing Survey of Food Intakes by Individuals, this article examines where and how much fresh and processed carrots are eaten and links this consumption to various economic, social, and demographic characteristics of consumers. The analysis indicates that per capita carrot consumption is greatest in the East and Central regions of the country. About 80 percent of fresh-market carrots are purchased at retail and consumed at home, with the majority consisting of fresh-cut (including baby) carrots.

  • Did BSE Announcements Reduce Beef Purchases?

    ERR-34, December 29, 2006

    ERS examines retail purchases of beef and beef products for evidence of response to the 2003 government announcements of finding cows infected with Bovine Spongiform Encephalopathy (BSE).

  • Possible Implications for U.S. Agriculture From Adoption of Select Dietary Guidelines

    ERR-31, November 20, 2006

    To help Americans meet nutritional requirements while staying within caloric recommendations, the 2005 Dietary Guidelines for Americans encourage consumption of fruits, vegetables, whole-grain products, and fat-free or low-fat milk or milk products. This report provides one view of the potential implications for U.S. agriculture if Americans changed their current consumption patterns to meet some of those guidelines. For Americans to meet the fruit, vegetable, and whole-grain recommendations, domestic crop acreage would need to increase by an estimated 7.4 million harvested acres, or 1.7 percent of total U.S. cropland in 2002. To meet the dairy guidelines, consumption of milk and milk products would have to increase by 66 percent; an increase of that magnitude would likely require an increase in the number of dairy cows as well as increased feed grains and, possibly, increased acreage devoted to dairy production.
