Cost and affordability of healthy diets: Adoption and use of a new food security metric worldwide

Spring 2026 Harry ’51 and Joshua ’49 Tsujimoto Perspectives in Global Development Seminar Series Speaker: Will Masters, Tufts university Abstract: This talk will describe the development and use of benchmark least-cost healthy diets, relative to available income, as a new metric of food access and nutrition security. Since 2022 these data have been published by the World Bank and UN agencies for global monitoring, and by national governments to guide their own agricultural investments, food policy and social protection. The metric is a designed for comparison to actual consumption, as a diagnostic indicator to distinguish among three possible causes of malnutrition: (a) high prices or unavailability for items in each food group needed for health, (b) insufficient income to buy those items in sufficient quantities, or (c) displacement of affordable low-cost healthy diets by different foods consumed for other reasons such as taste and preferences, time use and meal preparation costs, or food culture and aspirations shaped by marketing.
