Does a longer life mean a healthier life? The number of adults over 65 in the United States is growing, but many may not be aware that they are at greater risk from foodborne diseases and their nutritional needs change as they age. The IOM's Food Forum held a workshop October 29-30, 2009, to discuss food safety and nutrition concerns for older adults.

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.

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.

Food and nutrition security - identified via availability, access, utilization, and stability - and transitions to sustainable food systems are major discourses in the agro-food arena, as many countries today experience different forms of malnutrition simultaneously, such as child undernutrition, anemia among women, and adult obesity. Meanwhile, the triple burden of malnutrition (undernutrition, overnutrition, and micronutrient deficiency) is still widespread. Food Security and Nutrition explores integrated, context-specific approaches to food security challenges, emphasizing nutrition security as an integral component and addressing the implications of food content to food and nutrition security policies. Providing insight into these challenges through agricultural, policy, nutritional, geographic and sustainability lenses, Food Security and Nutrition is a valuable reference for food scientists and nutrition researchers working in food supply, food security, and nutrition security, and policy makers, investors, and other decision-makers seeking to address food insecurity around the world.

Food insecurity and low resources continue to be a burden influencing the health, well-being, growth, and development of millions of U.S. children and adults. Groups and individuals experiencing restrained access to food are our neighbors, individuals we may see each day, and individuals who we may not interact with or see because of their isolated situations. They include the elderly, those experiencing mental illness, veterans, certain race/ethnic groups, adolescents, young women with children, those living in rural areas, and those using food pantries, among others. Many of these groups, both hidden and visible, have rates of food insecurity above the national average that are resistant to national improvements in food security. Yet, attention to these subsets of the population is imperative to improve U.S. health and nutrition and to reduce rates of chronic disease. Many groups face specific barriers to maintaining sufficient food, for example, rural populations may find it difficult to access federal food assistance or other resources such as food pantries and nutrition education because of distance or lack of consistent internet access separating them from these resources. Further, their remote locations may make it difficult to obtain the types of foods that they prefer. Other specific barriers may include limited facilities and equipment for food preparation, access to culturally appropriate foods and preparation supplies, and foods that complement the foods that they already have. Tailored approaches to quantify access to food, the nutrition environment, dietary intake, and other barriers are necessary to build successful interventions and to quantify the needs of these populations.
