Assessing Changing Food Consumption Patterns


Book Description

The Food and Nutrition Board of the National Academy of Sciences under contract from the Food and Drug Administration (FDA) was charged to study the sources of data on food consumption and to suggest a system for integrating these data with data on nutrition and health status.




Food data collection in Household Consumption and Expenditure Surveys. Guidelines for low and middle income countries


Book Description

The measurement of food consumption and expenditure is a fundamental component of any analysis of poverty and food security, and hence the importance and timeliness of devoting attention to the topic cannot be overemphasized as the international development community confronts the challenges of monitoring progress in implementing the 2030 Agenda for Sustainable Development. In 2014, the International Household Survey Network published a desk review of the reliability and relevance of survey questions as included in 100 household surveys from low- and middle-income countries. The report was presented in March 2014 at the forty-fifth session of the United Nations Statistical Commission (UNSC), in a seminar organized by the Inter-Agency and Expert Group on Food Security, Agricultural and Rural Statistics (IAEG-AG). The assessment painted a bleak picture in terms of heterogeneity in survey design and overall relevance and reliability of the data being collected. On the positive side, it pointed to many areas in which even marginal changes to survey and questionnaire design could lead to a significant increase in reliability and consequently, great improvements in measurement accuracy. The report, which sparked a lot of interest from development partners and UNSC member countries, prompted IAEG-AG to pursue this area of work with the ultimate objective of developing, validating, and promoting scalable standards for the measurement of food consumption in household surveys. The work started with an expert workshop that took place in Rome in November 2014. Successive versions of the guidelines were drafted and discussed at various IAEG-AG meetings, and in another expert workshop organized in November 2016 in Rome. The guidelines were put together by a joint FAO-World Bank team, with inputs and comments received from representatives of national statistical offices, international organizations, survey practitioners, academics, and experts in different disciplines (statistics, economics, nutrition, food security, and analysis). A list of the main contributors is included in the acknowledgment section. In December 2017 a draft of the guidelines was circulated to 148 National Statistical Offices from low- to high-income countries for comments. The document was revised following that consultation and submitted to UNSC, which endorsed it at its forty-ninth session in March 2018 (under item 3(j) of the agenda, agricultural and rural statistics. The version presented here reflects what was endorsed by the Commission, edited for language. The process received support from the Global Strategy for Agricultural and Rural Statistics. The document is intended to be a reference document for National Statistical Offices, survey practitioners, and national and international agencies designing household surveys that involve the collection of food consumption and expenditure data.




Front-of-Package Nutrition Rating Systems and Symbols


Book Description

During the past decade, tremendous growth has occurred in the use of nutrition symbols and rating systems designed to summarize key nutritional aspects and characteristics of food products. These symbols and the systems that underlie them have become known as front-of-package (FOP) nutrition rating systems and symbols, even though the symbols themselves can be found anywhere on the front of a food package or on a retail shelf tag. Though not regulated and inconsistent in format, content, and criteria, FOP systems and symbols have the potential to provide useful guidance to consumers as well as maximize effectiveness. As a result, Congress directed the Centers for Disease Control and Prevention (CDC) to undertake a study with the Institute of Medicine (IOM) to examine and provide recommendations regarding FOP nutrition rating systems and symbols. The study was completed in two phases. Phase I focused primarily on the nutrition criteria underlying FOP systems. Phase II builds on the results of Phase I while focusing on aspects related to consumer understanding and behavior related to the development of a standardized FOP system. Front-of-Package Nutrition Rating Systems and Symbols focuses on Phase II of the study. The report addresses the potential benefits of a single, standardized front-label food guidance system regulated by the Food and Drug Administration, assesses which icons are most effective with consumer audiences, and considers the systems/icons that best promote health and how to maximize their use.




National Research Initiative


Book Description

Our nation faces daunting challenges to its food and fiber system and to the condition of our natural resources in the coming decades. Rapid increases in world population and the pressure on resources generated by increasing per capita consumption as a result of increasing per capita income challenge the very basis of our standard of livingâ€"our food, fiber, and natural-resource base. As the nation faces the challenges, new technologies and new information systems are changing the face of biologic research. The US Department of Agriculture (USDA) has traditionally been the nation's primary public research engine in food, fiber, and natural resources. The National Research Initiative Competitive Grants Program (NRI) is a small part of that USDA research effort, but it accounts for a substantial portion of the nation's merit-based peer-reviewed fundamental research efforts in food, fiber, and natural resources. In 1997, USDA asked the National Research Council Board on Agriculture (now the Board on Agriculture and Natural Resources) to conduct an independent assessment of the NRI program. Specifically, USDA asked the Research Council to: perform a retrospective assessment of the quality and value of research funded by the program; determine whether the science and technology priorities in the major NRI programs are defined appropriately; assess how NRI activities complement other USDA programs, those of other federal agencies, and state programs in the private sector; and recommend the nature and content of changes for the future. This report summarizes the results of the committee's analysis. Chapter 2 summarizes the value of food, fiber, and natural resources-research to the United States, focusing on economic contributions and rates of return of food and fiber research. The committee's analysis of the quality, value, fairness, relevance, and responsiveness of the NRI competitive grants program is presented in chapter 3. Chapter 4 presents the committee's analysis of the role and scope of the NRI, including its scientific objectives, its value in training and education, and its complementarity with other research activities. The committee's analysis of NRI's priority-setting process and its research priorities is given in chapter 5. The committee's analysis of organizational and funding issues is given in chapter 6. Chapter 7 presents the committee's recommendations to improve the effectiveness of the NRI program. Additional supporting materials are found in appendixes A through I.




Food Insecurity and Hunger in the United States


Book Description

The United States is viewed by the world as a country with plenty of food, yet not all households in America are food secure, meaning access at all times to enough food for an active, healthy life. A proportion of the population experiences food insecurity at some time in a given year because of food deprivation and lack of access to food due to economic resource constraints. Still, food insecurity in the United States is not of the same intensity as in some developing countries. Since 1995 the U.S. Department of Agriculture (USDA) has annually published statistics on the extent of food insecurity and food insecurity with hunger in U.S. households. These estimates are based on a survey measure developed by the U.S. Food Security Measurement Project, an ongoing collaboration among federal agencies, academic researchers, and private organizations. USDA requested the Committee on National Statistics of the National Academies to convene a panel of experts to undertake a two-year study in two phases to review at this 10-year mark the concepts and methodology for measuring food insecurity and hunger and the uses of the measure. In Phase 2 of the study the panel was to consider in more depth the issues raised in Phase 1 relating to the concepts and methods used to measure food security and make recommendations as appropriate. The Committee on National Statistics appointed a panel of 10 experts to examine the above issues. In order to provide timely guidance to USDA, the panel issued an interim Phase 1 report, Measuring Food Insecurity and Hunger: Phase 1 Report. That report presented the panel's preliminary assessments of the food security concepts and definitions; the appropriateness of identifying hunger as a severe range of food insecurity in such a survey-based measurement method; questions for measuring these concepts; and the appropriateness of a household survey for regularly monitoring food security in the U.S. population. It provided interim guidance for the continued production of the food security estimates. This final report primarily focuses on the Phase 2 charge. The major findings and conclusions based on the panel's review and deliberations are summarized.




Dietary Risk Assessment in the WIC Program


Book Description

Dietary Risk Assessment in the WIC Program reviews methods used to determine dietary risk based on failure to meet Dietary Guidelines for applicants to the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Applicants to the WIC program must be at nutritional risk to be eligible for program benefits. Although "dietary risk" is only one of five nutrition risk categories, it is the category most commonly reported among WIC applicants. This book documents that nearly all low-income women in the childbearing years and children 2 years and over are at risk because their diets fail to meet the recommended numbers of servings of the food guide pyramid. The committee recommends that all women and children (ages 2-4 years) who meet the eligibility requirements based on income, categorical and residency status also be presumed to meet the requirement of nutrition risk. By presuming that all who meet the categorical and income eligibility requirements are at dietary risk, WIC retains its potential for preventing and correcting nutrition-related problems while avoiding serious misclassification errors that could lead to denial of services for eligible individuals.




Pesticides in the Diets of Infants and Children


Book Description

Many of the pesticides applied to food crops in this country are present in foods and may pose risks to human health. Current regulations are intended to protect the health of the general population by controlling pesticide use. This book explores whether the present regulatory approaches adequately protect infants and children, who may differ from adults in susceptibility and in dietary exposures to pesticide residues. The committee focuses on four major areas: Susceptibility: Are children more susceptible or less susceptible than adults to the effects of dietary exposure to pesticides? Exposure: What foods do infants and children eat, and which pesticides and how much of them are present in those foods? Is the current information on consumption and residues adequate to estimate exposure? Toxicity: Are toxicity tests in laboratory animals adequate to predict toxicity in human infants and children? Do the extent and type of toxicity of some chemicals vary by species and by age? Assessing risk: How is dietary exposure to pesticide residues associated with response? How can laboratory data on lifetime exposures of animals be used to derive meaningful estimates of risk to children? Does risk accumulate more rapidly during the early years of life? This book will be of interest to policymakers, administrators of research in the public and private sectors, toxicologists, pediatricians and other health professionals, and the pesticide industry.
