Book's by Committee on the Application of Global Harmonization of Methodological Approaches to Nutrient Intake Recommendations for Young Children and Women of Reproductive Age
Recommended intake levels for nutrients and other dietary components were designed initially to prevent nutrient deficiency diseases in a given population, and the original methodological approach used to derive intake values did not include consideration for other applications. However, with the increasing globalization of information and the identification of a variety of factors specific to different population subgroups (e.g., young children and women of reproductive age) that influence their nutritional needs, there has been increasing recognition of the need to consider methodological approaches to deriving nutrient reference values (NRVs) that are applicable across countries and that take into account the varying needs of different population subgroups. There is a need for guidance and recommendations about methodological approaches, as well as their potential for application to an international process for the development of NRVs, and particularly for young children and women of reproductive age. Harmonization of Approaches to Nutrient Reference Values: Applications to Young Children and Women of Reproductive Age examines these issues and makes recommendations for a unified approach to developing NRVs that would be acceptable globally.

More than 16 million children in the United States live in food-insecure households where they are unable to obtain enough food to meet their needs. At the same time, a growing number of children are overweight or obese. Because of these challenges, improving child nutrition has emerged as one of the nation's most urgent public health needs. The Child and Adult Care Food Program (CACFP), a U.S. Department of Agriculture (USDA) food program, served about 3.3 million children in 2011, as well as more than 124,000 adults who require daily supervision or assistance. Since many children rely on CACFP for the majority of their daily food, the quality of foods provided has the potential to greatly improve the health of the children's diets. The USDA asked the IOM to review and recommend improvements, as necessary, to the CACFP meal requirements in order to keep them aligned with other federally funded food assistance programs and with the Dietary Guidelines for Americans. The 2011 IOM report, Child and Adult Care Food Program Aligning Dietary Guidance for All, reviewed the program in detail and provided recommendations for improvement. In February 2012, at the request of the USDA, the IOM conducted an additional workshop to examine research methods and approaches that could be used to design and conduct a nationally representative study assessing children's dietary intake and participation rates in child care facilities, including CACFP-sponsored child care centers and homes. Research Methods to Assess Dietary Intake and Program Participation in Child Day Care: Application to the Child and Adult Care Food Program Workshop Summary is the report that summarizes the workshop.
Since 1938 and 1941, nutrient intake recommendations have been issued to the public in Canada and the United States, respectively. Currently defined as the Dietary Reference Intakes (DRIs), these values are a set of standards established by consensus committees under the National Academies of Sciences, Engineering, and Medicine and used for planning and assessing diets of apparently healthy individuals and groups. In 2015, a multidisciplinary working group sponsored by the Canadian and U.S. government DRI steering committees convened to identify key scientific challenges encountered in the use of chronic disease endpoints to establish DRI values. Their report, Options for Basing Dietary Reference Intakes (DRIs) on Chronic Disease: Report from a Joint US-/Canadian-Sponsored Working Group, outlined and proposed ways to address conceptual and methodological challenges related to the work of future DRI Committees. This report assesses the options presented in the previous report and determines guiding principles for including chronic disease endpoints for food substances that will be used by future National Academies committees in establishing DRIs.
In this final report on the 'The influence of maternal, fetal and child nutrition on the development of chronic disease in later life', the Subgroup on Maternal and Child Nutrition (SMCN) reviews the evidence that early life nutrition exerts long-term effects and influences the risk of chronic disease in adulthood, bringing together findings from both observational and experimental studies, and considering implications for maternal and child nutrition in the UK. SACN concludes that there is cause for concern about the later health consequences of compromised or excessive nutrient supply during early fetal and infant life. It notes that in the context of reproduction, the impact of current dietary patterns on women and girls is of particular concern, and considers that improving the nutritional status of women of childbearing age, infants and young children has the potential to improve the health of future generations. The Committee also offers recommendations for future research in this area, particularly emphasising the need for data which better characterise dietary patterns and patterns of pre and postnatal growth.
Since 1997, the Institute of Medicine has issued a series of nutrient reference values that are collectively termed Dietary Reference Intakes (DRIs). The DRIs offer quantitative estimates of nutrient intakes to be used for planning and assessing diets. Using the information from these reports, this newest volume in the DRI series focuses on how the DRIs, and the science for each nutrient in the DRI reports, can be used to develop current and appropriate reference values for nutrition labeling and food fortification. Focusing its analysis on the existing DRIs, the book examines the purpose of nutrition labeling, current labeling practices in the United States and Canada, food fortification practices and policies, and offers recommendations as a series of guiding principles to assist the regulatory agencies that oversee food labeling and fortification in the United States and Canada. The overarching goal of the information in this book is to provide updated nutrition labeling that consumers can use to compare products and make informed food choices. Diet-related chronic diseases are a leading cause of preventable deaths in the United States and Canada and helping customers make healthy food choices has never been more important.
What foods should Americans eat to promote their health, and in what amounts? What is the scientific evidence that supports specific recommendations for dietary intake to reduce the risk of multifactorial chronic disease? These questions are critically important because dietary intake has been recognized to have a role as a key determinant of health. As the primary federal source of consistent, evidence-based information on dietary practices for optimal nutrition, the Dietary Guidelines for Americans (DGA) have the promise to empower Americans to make informed decisions about what and how much they eat to improve health and reduce the risk of chronic disease. The adoption and widespread translation of the DGA requires that they be universally viewed as valid, evidence-based, and free of bias and conflicts of interest to the extent possible. However, this has not routinely been the case. A first short report meant to inform the 2020 review cycle explored how the advisory committee selection process can be improved to provide more transparency, eliminate bias, and include committee members with a range of viewpoints. This second and final report recommends changes to the DGA process to reduce and manage sources of bias and conflicts of interest, improve timely opportunities for engagement by all interested parties, enhance transparency, and strengthen the science base of the process.
Food choices and eating habits are learned from many sources. The school environment plays a significant role in teaching and modeling health behaviors. For some children, foods consumed at school can provide a major portion of their daily nutrient intake. Foods and beverages consumed at school can come from two major sources: (1) Federally funded programs that include the National School Lunch Program (NSLP), the School Breakfast Program (SBP), and after-school snacks and (2) competitive sources that include vending machines, "a la carte" sales in the school cafeteria, or school stores and snack bars. Foods and beverages sold at school outside of the federally reimbursable school nutrition programs are referred to as competitive foods because they compete with the traditional school lunch as a nutrition source. There are important concerns about the contribution of nutrients and total calories from competitive foods to the daily diets of school-age children and adolescents. Nutrition Standards for Foods in Schools offers both reviews and recommendations about appropriate nutrition standards and guidance for the sale, content, and consumption of foods and beverages at school, with attention given to foods and beverages offered in competition with federally reimbursable meals and snacks. It is sure to be an invaluable resource to parents, federal and state government agencies, educators and schools, health care professionals, food manufacturers, industry trade groups, media, and those involved in consumer advocacy.
The federal government requires that most packaged foods carry a standardized label-the Nutrition Facts panel-that provides nutrition information intended to help consumers make healthful choices. In recent years, manufacturers have begun to include additional nutrition messages on their food packages. These messages are commonly referred to as 'front-of-package' (FOP) labeling. As FOP labeling has multiplied, it has become easy for consumers to be confused about critical nutrition information. In considering how FOP labeling should be used as a nutrition education tool in the future, Congress directed the Centers for Disease Control and Prevention to undertake a two-phase study with the IOM on FOP nutrition rating systems and nutrition-related symbols. The Food and Drug Administration is also a sponsor. In Phase 1 of its study, the IOM reviewed current systems and examined the strength and limitations of the nutrition criteria that underlie them. The IOM concludes that it would be useful for FOP labeling to display calorie information and serving sizes in familiar household measures. In addition, as FOP systems may have the greatest benefit if the nutrients displayed are limited to those most closely related to prominent health conditions, FOP labeling should provide information on saturated fats, trans fats, and sodium.
