This document discusses malnutrition in all its forms as a double burden for food policy. It notes that over 800 million people are hungry, 2 billion have micronutrient deficiencies, and nearly 2 billion are overweight or obese. Both undernutrition and obesity are driven by poor diet quality and the rising consumption of sugars, fats, and ultra-processed foods globally. Current approaches to undernutrition and obesity have been largely separate, but a double duty approach is needed that addresses the shared underlying causes. Food policy must improve overall diet quality, shift mindsets to addressing the double burden simultaneously, and introduce policies and leverage food systems to encourage healthy diets for all.
