Approaches to Assessing Intake of Food and Dietary Supplements in Pregnant Women and Children 2 to 11 Years of Age


Book Description

A virtual workshop series titled Approaches to Assessing Intake of Food and Dietary Supplements in Pregnant Women and Children 2 to 11 Years of Age was convened in May, 2021 by the Food and Nutrition Board of the National Academies of Sciences, Engineering, and Medicine. The four-day workshop series explored the evidence on methodological approaches to assessing intake of food and dietary supplements in pregnant women and children 2 to 11 years of age. Obtaining reliable and valid dietary intake information for these population groups is particularly difficult - in pregnancy, rapid changes in nutrient needs and dietary intakes occur, and in young children, much of dietary intake is consumed outside the home and is often misreported by the children or their proxy reporters. To advance the quality of the science in these areas, the workshop had four goals: identify the suite of current methods used in dietary assessments, including food and dietary supplements, in pregnant women and children 2 to 11 years of age; identify the methodological challenges and opportunities in improving current methods; explore methodologies in other disciplines and their application in dietary assessments in those populations; and discuss factors to consider when implementing dietary assessment tools in those populations. This publication summarizes the presentations and discussions of the workshop series.







Harmonization of Approaches to Nutrient Reference Values


Book Description

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.




Nutrition in the Prevention and Treatment of Disease


Book Description

Nutrition in the Prevention and Treatment of Disease, Fourth Edition, is a compilation of current knowledge in clinical nutrition and an overview of the rationale and science base of its application to practice in the prevention and treatment of disease. In its fourth edition, this text continues the tradition of incorporating new discoveries and methods related to this important area of research Generating and analyzing data that summarize dietary intake and its association with disease are valuable tasks in treating disease and developing disease prevention strategies. Well-founded medical nutrition therapies can minimize disease development and related complications. Providing scientifically sound, creative, and effective nutrition interventions is both challenging and rewarding. Two new chapters on metabolomics and translational research, which have come to be used in nutrition research in recent years. The new areas of study are discussed with the perspective that the application of the scientific method is by definition an evolutionary process. A new chapter on Genetics and Diabetes which reviews the latest research on causal genetic variants and biological mechanisms responsible for the disease, and explores potential interactions with environmental factors such as diet and lifestyle. Includes all major "omics" – the exposome, metabolomics, genomics, and the gut microbiome. Expands the microbiota portions to reflect complexity of diet on gut microbial ecology, metabolism and health




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.

Dietary Reference Intakes


Book Description

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.




Review of WIC Food Packages


Book Description

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) began 40 years ago as a pilot program and has since grown to serve over 8 million pregnant women, and mothers of and their infants and young children. Today the program serves more than a quarter of the pregnant women and half of the infants in the United States, at an annual cost of about $6.2 billion. Through its contribution to the nutritional needs of pregnant, breastfeeding, and post-partum women; infants; and children under 5 years of age; this federally supported nutrition assistance program is integral to meeting national nutrition policy goals for a significant portion of the U.S. population. To assure the continued success of the WIC, Congress mandated that the Food and Nutrition Service of the U.S. Department of Agriculture (USDA) reevaluate the program's food packages every 10 years. In 2014, the USDA asked the Institute of Medicine to undertake this reevaluation to ensure continued alignment with the goals of the Dietary Guidelines for Americans. In this third report, the committee provides its final analyses, recommendations, and the supporting rationale.




Dietary assessment


Book Description

FAO provides countries with technical support to conduct nutrition assessments, in particular to build the evidence base required for countries to achieve commitments made at the Second International Conference on Nutrition (ICN2) and under the 2016-2025 UN Decade of Action on Nutrition. Such concrete evidence can only derive from precise and valid measures of what people eat and drink. There is a wide range of dietary assessment methods available to measure food and nutrient intakes (expressed as energy insufficiency, diet quality and food patterns etc.) in diet and nutrition surveys, in impact surveys, and in monitoring and evaluation. Differenct indicators can be selected according to a study's objectives, sample population, costs and required precision. In low capacity settings, a number of other issues should be considered (e.g. availability of food composition tables, cultural and community specific issues, such as intra-household distribution of foods and eating from shared plates, etc.). This manual aims to signpost for the users the best way to measure food and nutrient intakes and to enhance their understanding of the key features, strengths and limitations of various methods. It also highlights a number of common methodological considerations involved in the selection process. Target audience comprises of individuals (policy-makers, programme managers, educators, health professionals including dietitians and nutritionists, field workers and researchers) involved in national surveys, programme planning and monitoring and evaluation in low capacity settings, as well as those in charge of knowledge brokering for policy-making.




Dietary Reference Intakes


Book Description

Since 1994 the Institute of Medicine's Food and Nutrition Board has been involved in developing an expanded approach to developing dietary reference standards. This approach, the Dietary Reference Intakes (DRIs), provides a set of four nutrient-based reference values designed to replace the Recommended Dietary Allowances (RDAs) in the United States and the Recommended Nutrient Intakes (RNIs) in Canada. These reference values include Estimated Average Requirement (EAR), Recommended Dietary Allowance (RDA), Adequate Intake (AI), and Tolerable Upper Intake Level (UL). To date, several volumes in this series have been published. This new book, Applications in Dietary Assessment, provides guidance to nutrition and health research professionals on the application of the new DRIs. It represents both a "how to" manual and a "why" manual. Specific examples of both appropriate and inappropriate uses of the DRIs in assessing nutrient adequacy of groups and of individuals are provided, along with detailed statistical approaches for the methods described. In addition, a clear distinction is made between assessing individuals and assessing groups as the approaches used are quite different. Applications in Dietary Assessment will be an essential companion to any-or all-of the DRI volumes.
