Nutrition And The Environment

Environmental Nutrition: Connecting Health and Nutrition with Environmentally Sustainable Diets explores the connection between diet, environmental sustainability and human health. Current food systems are a major contributor to our most pressing health and environmental issues, including climate change, water scarcity, food insecurity and chronic diseases. This book not only seeks to increase our understanding of the interrelatedness of these major global issues, but also aids in the creation of new solutions. Sections discuss the diet, the health and environment trilemma, food systems and their trends, environmental nutrition as an all-encompassing discipline, and the environmental nutrition model. Demonstrates how the food system, the environment and human health are inter-related Explores how dietary patterns impact food production and agriculture choices Identifies the imbalance between current food production relative to demand Addresses how the current food system negatively impacts the environment Provides practical solutions to how diets can be both healthy and sustainable

This discussion paper highlights the interlinkages between nutrition and the environment across various dimensions from policy to impact. It focuses on diets and food systems, which lie at the nutrition−environment nexus. The paper illustrates how dietary trends and food systems are contributing to the triple planetary crisis of climate change, biodiversity loss and pollution, as well as how that crisis is exacerbating nutrition challenges. It also presents a range of policy options and practical measures that generate co-benefits for people and the planet. Furthermore, the paper stresses the importance of interdisciplinary collaboration and innovative approaches in promoting positive change. In addition, it explores methodologies that can be used to weigh trade-offs in decision-making to help shift to sustainable solutions that support better human and planetary health. This paper is part of UN-Nutrition’s greater efforts to bridge the nutrition and environmental communities and related stakeholders that engage in food systems transformation.

Drawing upon 842 indexed journal studies from the fields of cell biology, toxicology, immunology, neurology and genetics, Environmental Nutrition offers a molecular-level understanding of the link between environment, food quality, and disease. Included in the book are in-depth explorations of controversial topics like food irradiation and pesticide use, evaluations of over 100 toxic substances commonly found in food, and a detailed cellular-level analysis of potential health implications. Strategies for the establishment of environmental standards in nutrition are outlined, including sustainable agriculture and organic food production. (304 pages, 112 tables and figures, 842 indexed journal references.)

Introduces nutrition by linking information on nutrients to an understanding of how food production and processing, and the impact of these on environmental quality, influence each person's nutritional status. Discusses how nutrients work in the body, why some foods are high or low in individual nutrients, how the body is harmed by deficiencies or excesses of nutrients, and why nutrient requirements change as we get older.

This book takes a transdisciplinary approach and considers multisectoral actions, integrating health, agriculture and environmental sector issues to comprehensively explore the topic of sustainable diets. The team of international authors informs readers with arguments, challenges, perspectives, policies, actions and solutions on global topics that must be properly understood in order to be effectively addressed. They position issues of sustainable diets as central to the Earth's future. Presenting the latest findings, they: - Explore the transition to sustainable diets within the context of sustainable food systems, addressing the right to food, and linking food security and nutrition to sustainability. - Convey the urgency of coordinated action, and consider how to engage multiple sectors in dialogue and joint research to tackle the pressing problems that have taken us to the edge, and beyond, of the planet's limits to growth. - Review tools, methods and indicators for assessing sustainable diets. - Describe lessons learned from case studies on both traditional food systems and current dietary challenges. As an affiliated project of the One Planet Sustainable Food Systems Programme, this book provides a way forward for achieving global and local targets, including the Sustainable Development Goals and the United Nations Decade of Action on Nutrition commitments. This resource is essential reading for scientists, practitioners, and students in the fields of nutrition science, food science, environmental sciences, agricultural sciences, development studies, food studies, public health and food policy.

This report is the outcome of a consensus-building project to agree on best practices for environmental and nutritional Life Cycle Assessment (nLCA) methodology, and identify future research needs. The project involved 30 nutritional and environmental LCA researchers from 18 countries. It focused on the assessment of food items (as opposed to meals or diets). Best practice recommendations were developed to address the intended purpose of an LCA study and related modeling approach, choice of an appropriate functional unit, assessment of nutritional value, and reporting nLCA results. An nLCA study should report the quantities of as many essential nutrients as possible and aim to provide information on the nutritional quality and/or health impacts in addition to nutrient quantities. Outstanding issues requiring further research attention include: defining a minimum number of nutrients to be considered in an nLCA study; treatment of nutrients to limit; use of nutrient indexes; further development of Impact Assessment methods; representation of nutritional changes that may occur during subsequent distribution and food preparation in cradle-to-gate nLCA studies; and communication of data uncertainty and variability. More data are required for different regions (particularly developing countries); for the processing, distribution, retail, and consumption life cycle stages; and for food loss and waste. Finally, there is a need to extend nLCA methodology for the assessment of meals and diets, to consider further how to account for the multi-functionality of food in a sustainability framework, and to set nLCA studies within the context of environmental limits. These results provide a robust basis for improving nLCA methodology and applying it to identify solutions that minimize the trade-offs between nourishing populations and safeguarding the environment.

Nearly 69 percent of U.S. adults and 32 percent of children are either overweight or obese, creating an annual medical cost burden that may reach $147 billion. Researchers and policy makers are eager to identify improved measures of environmental and policy factors that contribute to obesity prevention. The IOM formed the Committee on Accelerating Progress in Obesity Prevention to review the IOM's past obesity-related recommendations, identify a set of recommendations for future action, and recommend indicators of progress in implementing these actions. The committee held a workshop in March 2011 about how to improve measurement of progress in obesity prevention.
