This milestone references the dataset created to achieve Task 2.2 of FEAST WP2 “Explore adherence to and factors influencing healthy/sustainable dietary choices across Europe”. It involved the design of a cross-sectional EU-survey based on a quantitative questionnaire to collect primary data on dietary patterns; purchasing and consumption behaviours; barriers and facilitators to the adherence to healthier and more sustainable diets; and opinions on food system policies, from adult populations across the Europe.
