ROME — One in three people around the world cannot afford a healthy diet, the United Nations reported this week, in an annual assessment of global food security that found structural barriers to nutrition deepening in low- and middle-income countries even as the headline figures on hunger have remained stubbornly flat for three consecutive years.
The findings come from the 2026 edition of the State of Food Security and Nutrition in the World, published jointly by the Food and Agriculture Organization, the World Food Programme, and three other UN agencies. The report draws on household survey data, food price indices, and agricultural statistics from 139 countries to produce the most comprehensive global accounting available of who lacks access to nutritious food and why. The answer, in 2026, involves not only supply shortfalls but a persistent structural gap between the cost of a healthy diet and the incomes of billions of people who cannot bridge it.
The one-in-three figure, representing roughly 2.8 billion people, describes those for whom a diet meeting minimum nutritional standards, as defined by the FAO, is financially inaccessible. The figure is distinct from the narrower measure of undernutrition: approximately 733 million people experienced hunger defined as insufficient caloric intake in 2025, a number that has remained essentially flat for three years despite significant economic growth in parts of Asia and Latin America. The failure of economic expansion to translate into improved nutrition access reflects, the report argues, structural failures in food systems rather than simply aggregate income constraints.
What has grown alongside economic output is the disparity between food prices and real incomes in the world’s most food-insecure populations. Ultra-processed foods, cheap, calorie-dense, and nutritionally poor, are increasingly the default dietary option for the urban and rural poor in countries where healthy food systems have been disrupted by climate shocks, supply chain fragmentation, and prolonged conflict. The consequences compound across generations: children raised on poor-quality diets are at elevated risk of stunting from early malnutrition while simultaneously facing higher rates of diet-related obesity and non-communicable disease in adolescence and adulthood.
The geographic distribution of food insecurity is uneven. Sub-Saharan Africa faces the highest rates by every metric the report measures, with several countries recording the most extreme outcomes. Sudan, where more than two years of war have collapsed agricultural systems and displaced millions of farmers from their land, has specific populations in what the UN defines as catastrophic food insecurity. Somalia, facing compounding drought and displacement, is in a similar position. South Asia has shown modest improvement in some indicators but remains home to the largest absolute number of people who cannot afford a nutritious diet.
Climate change functions as a compounding factor across nearly every region the report examines. Crop failures driven by flooding, drought, and shifting growing seasons have increased price volatility for staple foods, disproportionately affecting countries with limited foreign exchange reserves or inadequate social protection systems to buffer import cost fluctuations. The FAO’s Food Price Index has remained elevated since the disruptions of 2022, with cereal and vegetable oil prices in particular staying above long-run historical averages in a way that erodes household food budgets in places where food absorbs 50 to 70 percent of household income.
The report documents what its authors call a triple burden of malnutrition: undernutrition, micronutrient deficiency, and diet-related non-communicable diseases often coexisting within the same countries, communities, and even households. The burden lands most heavily on women and young children. UN nutrition specialists note that the first 1,000 days of life, from conception to a child’s second birthday, represent a window in which nutritional deficits cause permanent developmental harm that no later intervention can fully reverse.
The policy implications extend well beyond humanitarian food aid. The World Bank has estimated the economic cost of malnutrition, measured in lost labor productivity, increased healthcare expenditure, and reduced educational attainment, at between three and sixteen percent of GDP in affected countries. The FAO’s report argues that investment in food systems, improving agricultural productivity, reducing post-harvest losses, connecting smallholder farmers to markets, and building social safety nets that enable poor families to afford nutritious food, is the lever most likely to address the structural deficit that food aid alone cannot close.
The alarming increase in global hunger documented three years ago marked the last time the trend line moved sharply upward. Since then, progress has stalled. The 2030 target to achieve zero hunger, established as Sustainable Development Goal 2, is now widely acknowledged within the UN system to be out of reach under current policy trajectories. The FAO’s most optimistic scenario places hunger above 600 million people by 2030, even if current development commitments are maintained in full, which they are not.
External funding for food assistance programs has not kept pace with need. The World Food Programme, which operates on voluntary contributions from member governments, has faced significant budget shortfalls in recent years and has cut rations in several emergency operations across Yemen, Sudan, and parts of East Africa. The United States, historically WFP’s largest contributor, has reduced its funding under the current administration, with consequences visible in reduced aid flows to some of the most severely affected populations the 2026 report documents.
The 2026 State of Food Security report does not offer a hopeful conclusion. It tracks what has not worked and why, and presents the available evidence on what might: sustained investment in agricultural resilience, trade policies that reduce food price volatility, and social protection systems capable of shielding the poorest households from commodity market fluctuations. Whether governments and international institutions will respond to that evidence with greater urgency than they have in the three years since the last alarm was raised is a question the report, by design, cannot answer.
