The 2nd Mediterranean Legume Innovation Network (M-LIN) workshop with the title, “Realising the ecological-health approach: consumers’ transition to legume-based diets” was held on the 9th of July 2019 in Porto, Portugal, hosted by Universidade Católica Portuguesa (UCP) and EUREST. The meeting brought together stakeholders interested in the topic of sustainable diets and to interact with members of the TRUE project. For this 2nd M-LIN the main objective was to involve a more representative number of health professionals and dietitians in the discussion, given their close relationship with the consumers and the importance of their knowledge in consumer advisory on diets and lifestyle. Assuming an ecological-health approach, the specific aims of this M-LIN were to understand: the main constraints in legumes inclusion in general diets, with special focus on children; legume policies hindering or enabling legumes consumption; health effects and nutritional status modulation by legumes; new product development and legume-based innovations.
