Despite sustained, gradual improvement in recent years, global hunger and food insecurity remain far above the targets set by the 2030 Agenda for Sustainable Development.

Yet, healthy diets are unaffordable for about 2.7 billion people worldwide. The 2026 edition of The State of Food Security and Nutrition in the World evaluates this pressing challenge, exploring the structural drivers behind the persistently high cost of a healthy diet.
