FNH-RI is an European research infrastructure for healthy and sustainable diets. We bring together the main players – researchers, citizen, data scientists, industry and technology developers – to boost research on eating patterns. To that end, we offer standards and procedures for data sharing, and harmonized protocols for tools, facilities and training. Ultimately, our goal is to foster the transition to sustainable food system, the reduction of non-communicable diseases and the engagement of consumer and citizen.
