联合国五个专门机构发布的《2026年世界粮食安全与营养状况》报告显示，2025年全球饥饿形势出现积极进展1。全球饥饿率降至7.8%，较2024年的8.1%和2022年的8.6%持续下降1，受饥饿影响的人数约为645万，相比2024年减少近1400万人1。与此同时，全球25.8%的人口（约21亿人）正经历中度或严重粮食不安全，较前一年的27.1%有所改善1。
然而这一改善在全球范围内分布极为不均。非洲饥饿人口绝对数最多，约309万人，其次是亚洲的292万人1。地区间的粮食不安全状况差异更为悬殊：非洲56.6%的人口面临中度或严重粮食不安全，远高于亚洲的20.3%、拉美加勒比的22.9%和北美欧洲的8.7%1。
获得营养充足饮食的成本持续上升，已成为新的障碍1。2025年健康饮食的平均成本上升至每人每天4.28购买力平价美元，较2021年的3.44美元明显增加1。全球32.7%的人口（26.9亿人）无法承受健康饮食，尽管这一比例较2021年的37.4%有所下降1。非洲面临最严峻的挑战，66.6%的人口无法承受健康饮食，这一比例是亚洲和拉美加勒比地区的两倍多1。
报告还指出了儿童营养和成人肥胖的长期困境1。全球仍有150万5岁以下儿童存在发育迟缓，而成人肥胖率从2012年的12.1%上升至2024年的16.2%1。展望未来，中东冲突的持续影响使得2030年全球饥饿人口的预测数据有所上升，预计为5.1至5.2亿人，较无冲突情景下的5.03亿增加1。
Five United Nations specialized agencies released the 2026 State of Food Security and Nutrition in the World report, revealing that global hunger rates have improved for a third consecutive year.1 The global hunger rate fell to 7.8 percent in 2025, down from 8.1 percent in 2024 and 8.6 percent in 2022, affecting approximately 645 million people worldwide.1 This represents a decline of nearly 14 million people from 2024 and 43 million fewer than in 2022.1
However, progress remains uneven across regions and populations. Approximately 25.8 percent of the global population, or 2.1 billion people, experienced moderate or severe food insecurity in 2025, an improvement from 27.1 percent in 2024.1 Africa bears the heaviest burden, with about 309 million people facing hunger compared to 292 million in Asia, making Africa home to the largest absolute number of hungry individuals.1 At the regional level, 56.6 percent of Africa's population faces moderate or severe food insecurity, far exceeding Asia's 20.3 percent, Latin America and the Caribbean's 22.9 percent, and Northern America and Europe's 8.7 percent.1
The affordability of nutritious diets presents another significant challenge. The average cost of a healthy diet rose to $4.28 in purchasing power parity per person per day in 2025, up from $3.44 in 2021.1 As a result, 32.7 percent of the global population—approximately 2.69 billion people—cannot afford a healthy diet, though this represents improvement from 37.4 percent in 2021.1 The burden falls disproportionately on Africa, where 66.6 percent of the population cannot afford healthy diets, more than double the rate in Asia and Latin America and the Caribbean.1
Malnutrition persists in other forms, with 1.5 million children under five experiencing stunting, while global adult obesity rates have climbed from 12.1 percent in 2012 to 16.2 percent in 2024.1 The report projects that ongoing Middle East conflicts could push global hunger to between 510 and 520 million people by 2030, compared to 503 million in scenarios without conflict.1
