Hidden hunger is not about providing enough calories, it is about a lack of micronutrients, which has life-long consequences for the children who are mostly affected. This begins with physical and cognitive developmental disorders and continues with an increased risk of non-communicable diseases and the occurrence of obesity. The book compiles the contributions of the Fourth Congress on Hidden Hunger 2019 as original articles. The focus of the congress was the problem of malnutrition and overweight, which can coexist and is termed a “double burden”. Part of the book deals with the causes of malnutrition and the challenge of achieving an agricultural system that is more focused on food quality. Another part discusses the causes and intervention approaches to tackling childhood obesity, especially in connection with malnutrition. All in all, this publication is a summary of important work by highly renowned authors on the topic of the congress: “Hidden Hunger and the Transformation of Food Systems: How to Combat the Double Burden of Malnutrition?” Like its two predecessors, the book fills an important gap by summarizing the essential aspects for science, applied research, and politics at a high level.

The U.S. food system provides many benefits, not the least of which is a safe, nutritious and consistent food supply. However, the same system also creates significant environmental, public health, and other costs that generally are not recognized and not accounted for in the retail price of food. These include greenhouse gas (GHG) emissions, soil erosion, air pollution, and their environmental consequences, the transfer of antibiotic resistance from food animals to human, and other human health outcomes, including foodborne illnesses and chronic disease. Some external costs which are also known as externalities are accounted for in ways that do not involve increasing the price of food. But many are not. They are borne involuntarily by society at large. A better understanding of external costs would help decision makers at all stages of the life cycle to expand the benefits of the U.S. food system even further. The Institute of Medicine (IOM) and the National Research Council (NRC) with support from the U.S. Centers for Disease Control and Prevention (CDC) convened a public workshop on April 23-23, 2012, to explore the external costs of food, methodologies for quantifying those costs, and the limitations of the methodologies. The workshop was intended to be an information-gathering activity only. Given the complexity of the issues and the broad areas of expertise involved, workshop presentations and discussions represent only a small portion of the current knowledge and are by no means comprehensive. The focus was on the environmental and health impacts of food, using externalities as a basis for discussion and animal products as a case study. The intention was not to quantify costs or benefits, but rather to lay the groundwork for doing so. A major goal of the workshop was to identify information sources and methodologies required to recognize and estimate the costs and benefits of environmental and public health consequences associated with the U.S. food system. It was anticipated that the workshop would provide the basis for a follow-up consensus study of the subject and that a central task of the consensus study will be to develop a framework for a full-scale accounting of the environmental and public health effects for all food products of the U.S. food system. Exploring Health and Environmental Costs of Food: Workshop Summary provides the basis for a follow-up planning discussion involving members of the IOM Food and Nutrition Board and the NRC Board on Agriculture and Natural Resources and others to develop the scope and areas of expertise needed for a larger-scale, consensus study of the subject.

In Britain, between 1980 and 1998, the number of people classified as obese tripled to 21per cent of women and 17 per cent of men. It is estimated that this costs the economy, as a whole, �2 billion and the NHS �0.5 billion in treatment. However the response of the NHS is patchy, with no national guidelines and only 28% of health authorities taking action to address the problem. There is little activity related to the management of obesity outside of general practice but only a small proportion of GPs follow a protocol. This report recommends that there should be strategies to reduce obesity and that the Department of Health should build on the plan in the National Service Framework on coronary heart disease and work with partners and professional bodies to clarify responsibilities. It should also work with the National Institute of Clinical excellence to disseminate information. The Department of Health should also lead a cross government strategy to promote the benefits of physical activity and there should be local targets to encourage cycling and walking. It should also work with the food industry to improve the balance of diet. Much of this work needs to be aimed at school children to promote a healthy lifestyle throughout life and guidance to schools on commercial sponsorship should be strengthened so that there is no conflict with messages on healthy eating.

Focuses on the economics of obesity. This work assesses the impact of food quality, access to fast food, food prices, legislation, and other factors on diet, physical activity, and body weight. It calculates the impact of obesity on hospital costs and examines the externalities imposed by obesity through health insurance.
