This book was released on 2015-06-17 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: How we produce and consume food has a bigger impact on Americans' well-being than any other human activity. The food industry is the largest sector of our economy; food touches everything from our health to the environment, climate change, economic inequality, and the federal budget. From the earliest developments of agriculture, a major goal has been to attain sufficient foods that provide the energy and the nutrients needed for a healthy, active life. Over time, food production, processing, marketing, and consumption have evolved and become highly complex. The challenges of improving the food system in the 21st century will require systemic approaches that take full account of social, economic, ecological, and evolutionary factors. Policy or business interventions involving a segment of the food system often have consequences beyond the original issue the intervention was meant to address. A Framework for Assessing Effects of the Food System develops an analytical framework for assessing effects associated with the ways in which food is grown, processed, distributed, marketed, retailed, and consumed in the United States. The framework will allow users to recognize effects across the full food system, consider all domains and dimensions of effects, account for systems dynamics and complexities, and choose appropriate methods for analysis. This report provides example applications of the framework based on complex questions that are currently under debate: consumption of a healthy and safe diet, food security, animal welfare, and preserving the environment and its resources. A Framework for Assessing Effects of the Food System describes the U.S. food system and provides a brief history of its evolution into the current system. This report identifies some of the real and potential implications of the current system in terms of its health, environmental, and socioeconomic effects along with a sense for the complexities of the system, potential metrics, and some of the data needs that are required to assess the effects. The overview of the food system and the framework described in this report will be an essential resource for decision makers, researchers, and others to examine the possible impacts of alternative policies or agricultural or food processing practices.

Download or read book Seafood Choices written by Institute of Medicine and published by National Academies Press. This book was released on 2007-03-09 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fragmented information that consumers receive about the nutritional value and health risks associated with fish and shellfish can result in confusion or misperceptions about these food sources. Consumers are therefore confronted with a dilemma: they are told that seafood is good for them and should be consumed in large amounts, while at the same time the federal government and most states have issued advisories urging caution in the consumption of certain species or seafood from specific waters. Seafood Choices carefully explores the decision-making process for selecting seafood by assessing the evidence on availability of specific nutrients (compared to other food sources) to obtain the greatest nutritional benefits. The book prioritizes the potential for adverse health effects from both naturally occurring and introduced toxicants in seafood; assesses evidence on the availability of specific nutrients in seafood compared to other food sources; determines the impact of modifying food choices to reduce intake of toxicants on nutrient intake and nutritional status within the U.S. population; develops a decision path for U.S. consumers to weigh their seafood choices to obtain nutritional benefits balanced against exposure risks; and identifies data gaps and recommendations for future research. The information provided in this book will benefit food technologists, food manufacturers, nutritionists, and those involved in health professions making nutritional recommendations.

Download or read book Toxicological Effects of Methylmercury written by National Research Council and published by National Academies Press. This book was released on 2000-09-27 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mercury is widespread in our environment. Methylmercury, one organic form of mercury, can accumulate up the aquatic food chain and lead to high concentrations in predatory fish. When consumed by humans, contaminated fish represent a public health risk. Combustion processes, especially coal-fired power plants, are major sources of mercury contamination in the environment. The U.S. Environmental Protection Agency (EPA) is considering regulating mercury emissions from those plants. Toxicological Effects of Methylmercury reviews the health effects of methylmercury and discusses the estimation of mercury exposure from measured biomarkers, how differences between individuals affect mercury toxicity, and appropriate statistical methods for analysis of the data and thoroughly compares the epidemiological studies available on methylmercury. Included are discussions of current mercury levels on public health and a delineation of the scientific aspects and policy decisions involved in the regulation of mercury. This report is a valuable resource for individuals interested in the public health effects and regulation of mercury. The report also provides an excellent example of the implications of decisions in the risk assessment process for a larger audience.

Download or read book Mercury Toxicity written by Nitish Kumar and published by Springer Nature. This book was released on 2023-12-25 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents mercury toxicity with respect to remediation and health issues. It covers sources of mercury contamination, its impact on human health, and prospective remediation by both bioremediation and phytoremediation with the application of recent advanced techniques such as genetic engineering and nanotechnology. Both anthropogenic activities and natural processes cause the release of mercury into different spheres of the environment resulting in severe adverse impacts. Increased anthropogenic discharge of mercury leads to disturbance in its natural biogeochemical cycle, which results in unenviable diseases and hazardous health effects. Mercury pollution is responsible for causing neurobehavioral, kidney, heart, gastrointestinal, liver, and other diseases. Many published works about the impact of mercury on health are also available worldwide; however, there is no complete understanding available on toxicological studies of mercury that covers the broader spectrum of findings ranging from sources of exposure to mercury toxicity to its remediation strategies. This book brings together a diverse group of environmental science, sustainability, and health researchers to address the challenges posed by global mass poisoning caused by mercury contamination. The book also proposes solutions to contamination through multi-disciplinary approaches. The book contains three sections. The first part describes the different sources and distribution of mercury in soil and plant ecosystems. The second part explains the health risks linked to mercury toxicity. The third part addresses sustainable mercury toxicity mitigation strategies and the potential applications of recent technology in providing solutions. This book is a valuable resource to students, academics, researchers, and environmental professionals working in the field of mercury contamination.

Download or read book Joint FAO WHO Expert Consultation on the Risks and Benefits of Fish Consumption written by World Health Organization and published by World Health Organization. This book was released on 2024-10-25 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolving science and debate concerning the benefits and risks of consuming fish have resulted in confusion over the years, and national and international food safety agencies have recognized the need to provide useful, clear and relevant information in this regard to consumers. In October 2023, FAO and WHO held the second Joint FAO/WHO Expert Consultation on the Risks and Benefits of Fish Consumption to analyse new scientific evidence on the matter and draw relevant conclusions and recommendations. The overall conclusions of the exercise show that consuming fish provides energy, protein and a range of other nutrients important for health, and that there are benefits related to fish consumption during all life stages (pregnancy, childhood and adulthood). General population studies show that the benefits and individual effects of fish consumption vary depending on overall diet, the characteristics of consumers, and the fish that is consumed.

Download or read book FAO WHO background document on the risks and benefits of fish consumption written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org. [Author] [Author]. This book was released on 2024-07-10 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report of the first Joint FAO/WHO Expert Consultation on the Risks and Benefits of Fish Consumption was published in 2010. Since then, new literature, data and information on the subject have become available. As such, FAO and WHO decided to generate a background report consisting of a comprehensive literature review, followed by an expert consultation, to update the report with new scientific evidence. This background document aims to provide scientific evidence about the risks and benefits of fish consumption in order to update the 2010 Report of the Joint FAO/WHO Expert Consultation on the Risks and Benefits of Fish Consumption. To provide new scientific evidence, five extensive literature reviews were conducted, focusing on the following five topics: 1. evidence of health benefits from fish consumption; 2. toxic effects of dioxins and dioxin-like polychlorinated biphenyls (dl-PCBs) (from studies published since 2010); 3. toxic effects of methylmercury (MeHg) (from studies published since 2010); 4. the role of selenium (Se) with regard to the health effects of MeHg; 5. occurrence data for MeHg, dioxins and dl-PCBs in fishery and aquaculture products (from studies published since 2010). The reviews followed a systematic approach, performing a systematic literature search and implementing elements from systematic literature reviews. A systematic review attempts to identify, appraise and synthesize all the empirical evidence that meets prespecified eligibility criteria to answer a specific research question.

Available in PDF, EPUB and Kindle. Book excerpt: "Mercury deposition and contamination is widespread and well documented, and it continues to be a public-health concern for certain sectors of the global human population in both developed and developing countries. This edited volume focuses on integrating the diverse sciences involved in the process of mercury cycling in the environment--from the atmosphere, through terrestrial and aquatic food webs, and human populations--to develop a comprehensive perspective on this important environmental pollutant. Using a systems-level approach, this book provides recommendations on mercury remediation, risk communication, education, and monitoring. In response to a growing need for understanding the cycling of this ubiquitous pollutant, the science of mercury has grown rapidly, expanding into several interdisciplinary fields and encompassing such disparate academic and scientific disciplines as biogeochemistry, economics, sociology, public health, decision sciences, physics, global change, and mathematics. Only recently have scientists really begun to establish more holistic approaches to studying mercury pollution, giving rise to investigations that have furthered the integration of a multi-tiered approach, especially by using chemistry, biology, and human health sciences collectively. The study of mercury pollution has produced a variety of contributions to domestic and international policies related to the management of mercury in the environment"-- Provided by publisher.
