Health, Wellbeing and Social Sciences.

For social interventions aimed at improving nutrition behavior evidence from randomized trials is essential but cannot be the only approach of research activities. Interventions on dietary habits require considerations on food security, economic and environmental sustainability, and a broad meaning of wellbeing which includes, but also goes beyond, health effects. The model of research in nutrition requires a new consideration of observational studies, mainly through different analytical models. Nutrition and food studies need research programs where medical (nutrition and health), psychology (how we behave), economics (how resources are used and their impact on wellbeing) and sociology (how social determinant shape behavior) collaborate.
