HDHL Food4Health addresses the intertwined challenges of food and diet-related Non Communicable Diseases (NCDs) and Climate Change by fostering collaboration and aligning research efforts across food, health, and environment areas. Through a participatory approach, HDHL Food4Health widens the HDHL network and organises co-creation workshops to identify common Research & Innovation (R&I) priorities. It aims to overcome siloed approaches by coordinating activities among government, academia, industry, and citizens, enhancing societal impact at national and regional levels. Leveraging its connections with researchers, policymakers, and other relevant stakeholders, HDHL supports its members in contributing to the Sustainable Development Goals (SDGs) by aligning food and health systems. The initiative facilitates joint funding calls and implements transdisciplinary research actions to maximise impact and address urgent societal challenges. By promoting collaboration and knowledge exchange, HDHL Food4Health aims to catalyse a shift towards healthier and more sustainable food systems, ultimately contributing to improved public health and environmental sustainability. The main objective of HDHL Food4Health is to align common R&I priorities among funding programmes by identifying research and policy needs, whilst continuing to align both with the Horizon Europe (HE) Partnerships and the needs identified by the European Commission.
