Available in PDF, EPUB and Kindle. Book excerpt: Dietary intake data collected in nationwide food consumption surveys are used for various policy, educational, and research purposes. Of interest is the distribution of the usual intake of a dietary component, where usual intake is an individual's long-run average intake of the component. The data available for analysis are a few daily intakes collected on each individual in a sample selected from a population according to a complex survey design. It is reasonable to treat a daily intake as the usual intake plus a measurement error. An estimation approach based on the analysis of transformed data is discussed. First, a least-squares regression spline is used to estimate a transformation that carries observed daily intakes into approximate normality. Then a measurement error model is fit to the transformed data, resulting in an estimated usual intake distribution in the transformed scale. Finally, the original transformation is used to develop an inverse transformation that maps the estimated transformed usual intake distribution back to the original scale. The regression spline model may be applied to the general problem of quantile estimation, where the sampled data are assumed to be realizations of a random variable Y with a smooth quantile function.

This book was released on 2020-11-09 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Harmonized approaches to setting recommendations for safe and appropriate dietary intakes and nutritional interventions are critical to support the resolution of differences across countries in setting national and international nutrition standards; promote consistency in public and clinical health objectives; provide a mechanism for designing national and international food and nutrition policies; and enhance the transparency of national standards for trade and other regulatory actions that have economic, health, and safety implications. Consistent dietary intake recommendations cannot be made without first establishing a consistent approach to derive reference values for population-level nutrient intakes. This tool kit is designed to help global stakeholders, including those in low- and middle-income countries, participate more easily in the process of implementing, disseminating, and evaluating a consistent and homogeneous methodological approach to the nutrient reference value process.

Download or read book Dietary Reference Intakes for Sodium and Potassium written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-07-26 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: As essential nutrients, sodium and potassium contribute to the fundamentals of physiology and pathology of human health and disease. In clinical settings, these are two important blood electrolytes, are frequently measured and influence care decisions. Yet, blood electrolyte concentrations are usually not influenced by dietary intake, as kidney and hormone systems carefully regulate blood values. Over the years, increasing evidence suggests that sodium and potassium intake patterns of children and adults influence long-term population health mostly through complex relationships among dietary intake, blood pressure and cardiovascular health. The public health importance of understanding these relationships, based upon the best available evidence and establishing recommendations to support the development of population clinical practice guidelines and medical care of patients is clear. This report reviews evidence on the relationship between sodium and potassium intakes and indicators of adequacy, toxicity, and chronic disease. It updates the Dietary Reference Intakes (DRIs) using an expanded DRI model that includes consideration of chronic disease endpoints, and outlines research gaps to address the uncertainties identified in the process of deriving the reference values and evaluating public health implications.
Download or read book School Meals written by Institute of Medicine and published by National Academies Press. This book was released on 2010-03-16 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ensuring that the food provided to children in schools is consistent with current dietary recommendations is an important national focus. Various laws and regulations govern the operation of school meal programs. In 1995, Nutrition Standards and Meal Requirements were put in place to ensure that all meals offered would be high in nutritional quality. School Meals reviews and provides recommendations to update the nutrition standard and the meal requirements for the National School Breakfast and Lunch Programs. The recommendations reflect new developments in nutrition science, increase the availability of key food groups in the school meal programs, and allow these programs to better meet the nutritional needs of children, foster healthy eating habits, and safeguard children's health. School Meals sets standards for menu planning that focus on food groups, calories, saturated fat, and sodium and that incorporate Dietary Guidelines for Americans and the Dietary Reference Intakes. This book will be used as a guide for school food authorities, food producers, policy leaders, state/local governments, and parents.
Download or read book Total Diet Studies written by Gerald G. Moy and published by Springer Science & Business Media. This book was released on 2013-11-08 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unless a food is grossly contaminated, consumers are unable to detect through sight or smell the presence of low levels of toxic chemicals in their foods. Furthermore, the toxic effects of exposure to low levels of chemicals are often manifested slowly, sometimes for decades, as in the case of cancer or organ failure. As a result, safeguarding food from such hazards requires the constant monitoring of the food supply using sophisticated laboratory analysis. While the food industry bears the primary responsibility for assuring the safety of its products, the overall protection of people’s diets from chemical hazards must be considered one of the most important public health functions of any government. Unfortunately, many countries do not have sufficient capability and capacity to monitor the exposure of their populations to many potentially toxic chemicals that could be present in food and drinking water. Without such monitoring, public health authorities in many countries are not able to identify and respond to problems posed by toxic chemicals, which may harm their population and undermine consumer confidence in the safety of the food supply. From a trade perspective, those countries that cannot demonstrate that the food they produce is free of potentially hazardous chemicals will be greatly disadvantaged or even subject to sanctions in the international marketplace. The goal of a total diet study (TDS) is to provide basic information on the levels and trends of exposure to chemicals in foods as consumed by the population. In other words, foods are processed and prepared as typical for a country before they are analyzed in order to better represent actual dietary intakes. Total diet studies have been used to assess the safe use of agricultural chemicals (e.g., pesticides, antibiotics), food additives (e.g., preservatives, sweetening agents), environmental contaminants (e.g., lead, mercury, arsenic, cadmium, PCBs, dioxins), processing contaminants (e.g., acrylamide, polycyclic aromatic hydrocarbons, chloropropanols), and natural contaminants (e.g., aflatoxin, patulin, other mycotoxins) by determining whether dietary exposure to these chemicals are within acceptable limits. Total diet studies can also be applied to certain nutrients where the goal is to assure intakes are not only below safe upper limits, but also above levels deemed necessary to maintain good health. International and national organizations, such as the World Health Organization, the European Food Safety Agency and the US Food and Drug Administration recognize the TDS approach as one of the most cost-effective means of protecting consumers from chemicals in food, for providing essential information for managing food safety, including food standards, and for setting priorities for further investment and study. Total Diet Studies introduces the TDS concept to a wider audience and presents the various steps in the planning and implementation of a TDS. It illustrates how TDSs are being used to protect public health from chemicals in the food supply in many developed and developing countries. The book also examines some of the applications of TDSs to specific chemicals, including contaminants and nutrients.

Download or read book Nutrition in Lifestyle Medicine written by James M. Rippe and published by Humana Press. This book was released on 2016-12-29 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: This newest addition to the Nutrition and Health series focuses on nutrition’s key role in lifestyle interventions to prevent and manage diseases. The book pays particular attention to nutritional considerations related to obesity, diabetes, and cardiovascular disease. Edited by cardiologist, Dr. James Rippe, a well-known expert in the nascent specialty of Lifestyle Medicine, Nutrition in Lifestyle Medicine will also focus on a variety of specialized areas such as nutrition for athletes and physically active individuals, hydration, and nutrition throughout the life cycle (spanning from children to individuals over the age of 60). In addition, chapters will be included on controversies in nutrition, such as health effects of added sugars and saturated fatty acids in the diet. Finally, specialized chapters will be included in such areas as nutrition for women, nutrition for men, nutrition for latinos, the use of supplements, communication about nutrition, public policy issues, and the interface between nutrition and physical activity. Lifestyle Medicine, supported by the American Journal of Lifestyle Medicine, Dr. Rippe’s textbook Lifestyle Medicine (CRC Press, 2013) and American College of Lifestyle Medicine (ACLM), is a new national medicine specialty that stresses the use of lifestyle interventions in the treatment and management of disease. Its practitioners effectively manage medical treatments alongside the lifestyle interventions, for example lowering insulin treatment for patients with diabetes, reducing the dose of anti-hypertension medications for people with hypertension, and prescribing certain medical interventions that aid in smoking cessation.
Download or read book Child and Adult Care Food Program written by Institute of Medicine and published by National Academies Press. This book was released on 2011-06-06 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Child and Adult Care Food Program (CACFP) is a federally-funded program designed to provide healthy meals and snacks to children and adults while receiving day care at participating family day care homes, traditional child care centers, afterschool facilities, adult care facilities, and emergency shelters. CACFP has the broadest scope of any of the U.S. Department of Agriculture (USDA) food program, serving more than 3 million children and 114,000 adults across the nation. To receive reimbursement for the foods served, participating programs must abide by requirements set by the USDA. Child and Adult Care Food Program assesses the nutritional needs of the CACFP population based on Dietary Guidelines for Americans and the Dietary Reference Intakes (DRIs) and makes recommendations for revisions to the CACFP meal requirements. The book outlines meal requirements that include food specifications that could be used for specific meals and across a full day, covering all age groups from infants to older adults and meal patterns designed for use in a variety of settings, including in-home care and in large centers. By implementing these meal requirements, consumption of fruits, vegetables, and whole-grain rich foods will increase while consumption of solid fats, added sugars, and sodium will decrease. Not only will this address the high prevalence of childhood obesity, it will also help to achieve consistency with the standards and regulations of other USDA nutrition assistance programs, particularly the Supplemental Nutrition Program for Women, Infants, and Children (WIC), and the National School Lunch and School Breakfast programs. Child and Adult Care Food Program makes practical recommendations that would bring CACFP meals and snacks into alignment with current dietary guidance. The book will serve as a vital resource for federal and state public health officials, care providers working in child and adult day care facilities, WIC agencies, officials working with the National School Lunch and School Breakfast programs, and other organizations serving at-risk populations.
Download or read book Dietary Reference Intakes for Vitamin C Vitamin E Selenium and Carotenoids written by Institute of Medicine and published by National Academies Press. This book was released on 2000-08-27 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the newest release in the authoritative series of quantitative estimates of nutrient intakes to be used for planning and assessing diets for healthy people. Dietary Reference Intakes (DRIs) is the newest framework for an expanded approach developed by U.S. and Canadian scientists. This book discusses in detail the role of vitamin C, vitamin E, selenium, and the carotenoids in human physiology and health. For each nutrient the committee presents what is known about how it functions in the human body, which factors may affect how it works, and how the nutrient may be related to chronic disease. Dietary Reference Intakes provides reference intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for different groups based on age and gender, along with a new reference intake, the Tolerable Upper Intake Level (UL), designed to assist an individual in knowing how much is "too much" of a nutrient.
Download or read book Dietary Reference Intakes written by Institute of Medicine and published by National Academies Press. This book was released on 1999-05-07 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: The model for risk assessment of nutrients used to develop tolerable upper intake levels (ULs) is one of the key elements of the developing framework for Dietary Reference Intakes (DRIs). DRIs are dietary reference values for the intake of nutrients and food components by Americans and Canadians. The U.S. National Academy of Sciences recently released two reports in the series (IOM, 1997, 1998). The overall project is a comprehensive effort undertaken by the Standing Committee on the Scientific Evaluation of Dietary Reference Intakes (DRI Committee) of the Food and Nutrition Board (FNB), Institute of Medicine, National Academy of Sciences in the United States, with active involvement of Health Canada. The DRI project is the result of significant discussion from 1991 to 1996 by the FNB regarding how to approach the growing concern that one set of quantitative estimates of recommended intakes, the Recommended Dietary Allowances (RDAs), was scientifically inappropriate to be used as the basis for many of the uses to which it had come to be applied.
