Resumo(s)
The transition to sustainable food systems is essential to address global challenges such as climate change, biodiversity loss and public health crises. Current food production and consumption patterns contribute to environmental degradation, while dietary choices strongly influence health outcomes and planetary sustainability. Supporting dietary decisions with robust scientific evidence is therefore essential for meaningful and informed change.
This work aims to discuss the intersection of food system transitions, dietary health impacts and sustainability, highlighting the importance of a comprehensive evidence-based approach to guide decisions at individual and systemic levels. By integrating methodologies such as Risk-Benefit Assessment (RBA) and Life Cycle Sustainability Assessment (LCSA), this study provides an approach to evaluating foods, dietary patterns and food choices. RBA considers risks (e.g. food contaminants) and benefits (e.g. beneficial nutrients), while LCSA assesses the environmental, social and economic dimensions of food production and consumption.
Inspired by the ALTERNATIVA project , the integration of these two perspectives, complemented by additional tools such as Multi-Criteria Decision Analysis (MCDA), will be explored and synthesised. The combination of these methodologies enables a dual-angle approach that quantifies health outcomes alongside sustainability metrics, providing a framework for balancing dietary health benefits with sustainable food systems.
This approach not only informs recommendations for healthier and more sustainable diets but also supports policymakers and stakeholders in developing strategies for food system transformation. By bridging gaps between food system actors and aligning public health goals with environmental sustainability, this evidence-based framework promotes a holistic vision for the agri-food sector and empowers consumers and stakeholders to make better choices that benefit both humans and the planet.
