USP Researchers Publish Landmark Study on Healthy Food Costs in Brazilian Urban Areas
The Universidade de São Paulo’s Faculdade de Saúde Pública has released new research examining the evolving costs of healthy and sustainable food baskets across Brazil, with particular attention to metropolitan regions. The study, published in 2026 in Revista de Saúde Pública, analyzes data from 2009 to 2024 and highlights challenges in urban nutrition economics.
Background on USP’s Public Health Research Tradition
USP has long been a leader in nutrition and public health studies in Brazil. Faculty and researchers at the Faculdade de Saúde Pública regularly contribute to national discussions on food security, dietary patterns, and economic barriers to healthy eating. This latest publication continues that legacy by focusing on the affordability of recommended food baskets in urban settings where most Brazilians reside.
Key Findings from the 2009–2024 Analysis
The research tracks both nominal and real costs of a proposed healthy and sustainable basic food basket. It covers national trends as well as specific metropolitan areas, providing a detailed picture of how prices have changed over 15 years. The study also estimates the share of family budgets required to purchase these baskets and examines shifts in the cost composition of different food groups.
Urban Focus and Metropolitan Region Insights
Brazil’s major cities face unique pressures in food access and pricing. The USP analysis pays special attention to metropolitan regions, where population density, supply chains, and income disparities can amplify the economic challenges of maintaining nutritious diets. Findings underscore the need for targeted policies that address urban-specific cost dynamics.

Economic Implications for Brazilian Households
Rising or fluctuating costs of healthy foods can influence household purchasing decisions, potentially widening gaps in nutrition outcomes. The study provides data that policymakers, economists, and public health experts can use to design interventions such as subsidies, price monitoring, or support for local production that improves affordability in cities.
Connection to Broader Nutrition Economics Research at Brazilian Universities
USP’s work sits within a growing body of research from Brazilian higher education institutions on food prices, consumption patterns, and health outcomes. Similar studies from other universities have examined income effects on fruit and vegetable purchases and price trends during economic disruptions, reinforcing the importance of academic contributions to national food policy.
Policy Relevance and Potential Applications
Government agencies and municipal planners can draw on the study’s longitudinal data to assess progress toward food security goals. The research offers evidence-based benchmarks for evaluating the effectiveness of existing programs and identifying where additional support may be needed to keep healthy options within reach for urban residents.
Impact on Nutrition Education and Training Programs
The publication also has implications for university curricula in nutrition, public health, and economics. Students at USP and peer institutions can use the findings as case studies when exploring real-world applications of dietary guidelines, cost-benefit analysis, and sustainable food systems in the Brazilian context.

Future Research Directions and Data Needs
Continued monitoring of food basket costs will be essential as economic conditions, supply chains, and consumer preferences evolve. USP researchers and collaborators at other Brazilian universities are well positioned to extend this work with updated datasets and deeper analysis of regional variations within metropolitan areas.
USP’s Role in Advancing Evidence-Based Public Health
By producing rigorous, publicly accessible research, USP strengthens Brazil’s capacity to address nutrition challenges through science. The 2026 study exemplifies how university-led inquiry can inform both academic discourse and practical solutions for healthier urban living.
