At the 2013 Nutrition for Growth Summit in London, 96 signatories (governments, civil society organizations, donors, United Nations’ agencies, and businesses) agreed to support the creation of an annual report on global nutrition that would be authored by an independent expert group, in partnership with a large number of contributors. The first edition of this report, the Global Nutrition Report 2014, puts a spotlight on worldwide progress by the 193 member countries of the United Nations in improving their nutrition status, identifies bottlenecks to change, highlights opportunities for action, and contributes to strengthened nutrition accountability on country and global levels.

Updates for many countries have made it possible to estimate hunger in the world with greater accuracy this year. In particular, newly accessible data enabled the revision of the entire series of undernourishment estimates for China back to 2000, resulting in a substantial downward shift of the series of the number of undernourished in the world. Nevertheless, the revision confirms the trend reported in past editions: the number of people affected by hunger globally has been slowly on the rise since 2014. The report also shows that the burden of malnutrition in all its forms continues to be a challenge. There has been some progress for child stunting, low birthweight and exclusive breastfeeding, but at a pace that is still too slow. Childhood overweight is not improving and adult obesity is on the rise in all regions. The report complements the usual assessment of food security and nutrition with projections of what the world may look like in 2030, if trends of the last decade continue. Projections show that the world is not on track to achieve Zero Hunger by 2030 and, despite some progress, most indicators are also not on track to meet global nutrition targets. The food security and nutritional status of the most vulnerable population groups is likely to deteriorate further due to the health and socio economic impacts of the COVID-19 pandemic. The report puts a spotlight on diet quality as a critical link between food security and nutrition. Meeting SDG 2 targets will only be possible if people have enough food to eat and if what they are eating is nutritious and affordable. The report also introduces new analysis of the cost and affordability of healthy diets around the world, by region and in different development contexts. It presents valuations of the health and climate-change costs associated with current food consumption patterns, as well as the potential cost savings if food consumption patterns were to shift towards healthy diets that include sustainability considerations. The report then concludes with a discussion of the policies and strategies to transform food systems to ensure affordable healthy diets, as part of the required efforts to end both hunger and all forms of malnutrition.

Few challenges facing the global community today match the scale of malnutrition, a condition that directly affects 1 in 3 people. Malnutrition manifests itself in many different ways: as poor child growth and development; as individuals who are skin and bone or prone to infection; as those who are carrying too much weight or whose blood contains too much sugar, salt, fat, or cholesterol; or those who are deficient in important vitamins or minerals. Malnutrition and diet are by far the biggest risk factors for the global burden of disease: every country is facing a serious public health challenge from malnutrition. The economic consequences represent losses of 11 percent of gross domestic product (GDP) every year in Africa and Asia, whereas preventing malnutrion delivers $16 in returns on investment for every $1 spent. The world’s countries have agreed on targets for nutrition, but despite some progress in recent years the world is off track to reach those targets. This third stocktaking of the state of the world’s nutrition points to ways to reverse this trend and end all forms of malnutrition by 2030.

As we move into the post-2015 era of the Sustainable Development Goals (SDGs), the world faces many seemingly intractable problems. Malnutrition should not be one of them. Countries that are determined to make rapid advances in malnutrition reduction can do so. If governments want to achieve the SDG target of ending all forms of malnutrition by 2030, they have clear pathways to follow. There are many levers to pull, and this report provides many examples of countries that have done so. Tackling malnutrition effectively is also key to meeting many other SDG targets. Good nutrition signals the realization of people’s rights to food and health. It reflects a narrowing of the inequalities in our world. Without good nutrition, human beings cannot achieve their full potential. When people’s nutrition status improves, it helps break the intergenerational cycle of poverty, generates broad-based economic growth, and leads to a host of benefits for individuals, families, communities, and countries. Good nutrition provides both a foundation for human development and the scaffolding needed to ensure it reaches its full potential. Good nutrition, in short, is an essential driver of sustainable development.

Good nutrition is the bedrock upon which to build healthy lives, strong and resilient livelihoods, and thriving economies. In its absence, their construction takes place on quicksand. Stunted children fail to grow and develop properly, with impairment to brains and immune systems being particular problems. Malnourished women of childbearing age do not have enough iron in their blood to feed their muscles. Many adults carry so much excess weight they put their heart and lungs under extreme stress and may suffer from diabetes, hypertension, and heart disease. Malnutrition leads to 11 percent of gross national product being squandered as a result of lives lost, less learning in school, less earning in the workplace, and days lost to illness. And malnourished mothers are more likely to give birth to malnourished newborns, perpetuating the intergenerational transmission of poverty. Malnutrition corrodes the body, the economy, and the future. Ambitions for sustainable development are likely to be thwarted by its presence.

More children born today will survive to adulthood than at any time in history. It is now time to emphasize health and development in middle childhood and adolescence--developmental phases that are critical to health in adulthood and the next generation. Child and Adolescent Health and Development explores the benefits that accrue from sustained and targeted interventions across the first two decades of life. The volume outlines the investment case for effective, costed, and scalable interventions for low-resource settings, emphasizing the cross-sectoral role of education. This evidence base can guide policy makers in prioritizing actions to promote survival, health, cognition, and physical growth throughout childhood and adolescence.

As we move into the post-2015 era of the Sustainable Development Goals (SDGs), the world faces many seemingly intractable problems. Malnutrition should not be one of them. Countries that are determined to make rapid advances in malnutrition reduction can do so, and the incentives to improve nutrition are strong. Good nutrition provides a vital foundation for human development, central to meeting our full potential. When nutrition status improves, it leads to a host of positive outcomes for individuals and families. Many more children will live to see their fifth birthdays, their growth will be less disrupted, and they will gain in height and weight. They will learn more in school because their brain function is not impaired. As a result of this positive early environment, as adults they will have better jobs and get ill less often. Older adults will age more healthily and live longer.

New evidence this year corroborates the rise in world hunger observed in this report last year, sending a warning that more action is needed if we aspire to end world hunger and malnutrition in all its forms by 2030. Updated estimates show the number of people who suffer from hunger has been growing over the past three years, returning to prevailing levels from almost a decade ago. Although progress continues to be made in reducing child stunting, over 22 percent of children under five years of age are still affected. Other forms of malnutrition are also growing: adult obesity continues to increase in countries irrespective of their income levels, and many countries are coping with multiple forms of malnutrition at the same time – overweight and obesity, as well as anaemia in women, and child stunting and wasting.

In recent years, the world has seen unprecedented attention and political commitment to addressing malnutrition. Milestones such as the Scaling Up Nutrition (SUN) Movement, the Lancet Maternal and Child Nutrition Series, and the Second International Conference on Nutrition (ICN2) have marked the rapid rise of nutrition on the global policy and research agenda. These developments reverse years of relative neglect for nutrition. Undernutrition is a global challenge with huge social and economic costs. It kills millions of young children annually, stunts growth, erodes child development, reduces the amount of schooling children attain, and increases the likelihood of their being poor as adults, if they survive. Stunting persists through a lifetime and beyond—underweight mothers are more likely to give birth to underweight children, perpetuating undernutrition across generations. Undernutrition reduces global gross domestic product by US$1.4–$2.1 trillion a year—the size of the total economy of Africa south of the Sahara.

This report issues a call for urgent action to combat the growing epidemic of obesity, which now affects developing and industrialized countries alike. Adopting a public health approach, the report responds to both the enormity of health problems associated with obesity and the notorious difficulty of treating this complex, multifactorial disease. With these problems in mind, the report aims to help policy-makers introduce strategies for prevention and management that have the greatest chance of success. The importance of prevention as the most sensible strategy in developing countries, where obesity coexists with undernutrition, is repeatedly emphasized. Recommended lines of action, which reflect the consensus reached by 25 leading authorities, are based on a critical review of current scientific knowledge about the causes of obesity in both individuals and populations. While all causes are considered, major attention is given to behavioural and societal changes that have increased the energy density of diets, overwhelmed sophisticated regulatory systems that control appetite and maintain energy balance, and reduced physical activity. Specific topics discussed range from the importance of fat content in the food supply as a cause of population-wide obesity, through misconceptions about obesity held by both the medical profession and the public, to strategies for dealing with the alarming prevalence of obesity in children. "... the volume is clearly written, and carries a wealth of summary information that is likely to be invaluable for anyone interested in the public health aspects of obesity and fatness, be they students, practitioner or researcher." - Journal of Biosocial Science
