Dietary reference values for energy
Dietary reference values (DRVs) for energy are based on estimating the total energy expenditure (TEE) for groups of people. TEE provides a measure of the energy requirement at energy balance i.e. when energy intake matches energy expenditure. The methodology to measure TEE - the doubly labelled water (DLW) method - has advanced and as a result, the evidence base on TEE in a wide variety of population groups has expanded considerably. With the high levels of overweight and obesity currently seen in the UK and the wealth of new data now available, it was considered timely for the Scientific Advisory Committee on Nutrition (SACN) to review recommendations for the UK population. This report deta...

Healthy Ageing
Year on year, countries across the world continue to see an increase in life expectancy, largely attributed to the impact of modern medicine and disease eradication. There is now increasing evidence that environmental factors such as diet and lifestyle also have a significant role to play. However with this increase in years there often comes an unfortunate rise in chronic morbidity, with the quality of later life severely compromised by ill health. With age being the single greatest risk factor for a large proportion of common medical conditions, this latest report from the British Nutrition Foundation looks in detail at the role nutrition and physical activity can play in ensuring that the...
Nutrition and Development
This Task Force report reviews the evidence that the seeds of many adult diseases are sown in utero and in infancy. The report, written by experts in the field, summarises current knowledge in this area. It illustrates how early life nutrition can bring about changes in organ development and function, thus programming risk of disease in adult life. It also considers what might be done in early life to reduce the burden of future ill health. Nutrition and Development: Short- and Long-Term Consequences for Health includes chapters on the history of this topic area, normal growth and development, and current recommendations and practice in relation to nutrition and diet in early life. Chapters ...
Manual of Nutrition
This new edition of the Manual of Nutrition describes the major nutrients, their roles and sources, together with mechanisms of digestion and utilisation. It outlines how this links to food and nutrition policy, providing a valuable contribution to the understanding of the role food plays in our health and wellbeing. This edition covers similar ground to the previous editions but contains updated values for the typical nutrient content of commonly eaten foods as well as the nutrient intake of the population which has been estimated from recent research. The chapter on energy (Chapter 5) has been updated to include new information from the Scientific Advisory Committee on Nutrition's energy report "Dietary Reference Values for Energy" (2011, ISBN 9780108511370). Other updated information includes that related to iron, caffeine intake for pregnant women and recommendations on being active.

Optimizing the Process for Establishing the Dietary Guidelines for Americans
Federal guidance on nutrition and diet is intended to reflect the state of the science and deliver the most reliable recommendations possible according to the best available evidence. This guidance, updated and presented every 5 years in the Dietary Guidelines for Americans (DGA), serves as the basis for all federal nutrition policies and nutrition assistance programs, as well as nutrition education programs. Despite the use of the guidelines over the past 30 years, recent challenges prompted Congress to question the process by which food and nutrition guidance is developed. This report assesses the process used to develop the guidelines; it does not evaluate the substance or use of the guidelines. As part of an overall, comprehensive review of the process to update the DGA, this first report seeks to discover how the advisory committee selection process can be improved to provide more transparency, eliminate bias, and include committee members with a range of viewpoints for the purpose of informing the 2020 cycle.
Food and Drug Administration Advisory Committees
Like many other agencies of the federal government, the Food and Drug Administration (FDA) relies extensively on external advisory committees for independent scientific and technical advice. Recognizing that the existing advisory committee system is essentially sound, this volume recommends ways of enhancing the use of these committees in the evaluation of drugs, biological materials, and medical devices; strengthening the agency's management of the system; and increasing the accountability of the system to the public. In doing so, it examines and makes recommendations on such issues as the recruitment of committee members, the FDA's management of financial conflict of interest and intellectual bias among members, and the operations and management of the advisory committee system.
