Humanity’s challenge in the 21st century is to eradicate poverty and achieve prosperity for all within the means of the planet’s limited natural resources. In the run-up to Rio+20, this discussion paper presents a visual framework – shaped like a doughnut – which brings planetary boundaries together with social boundaries, creating a safe and just space between the two, in which humanity can thrive. Moving into this space demands far greater equity – within and between countries – in the use of natural resources, and far greater efficiency in transforming those resources to meet human needs.

Hungry city. How food shapes our lives
26 octobre 2021, par Mathilde COUDRAYHow do you feed a city ? It’s a question that we rarely ask, but which lies at the core of civilisation. The feeding of cities arguably has a greater social and physical impact on us and our planet than anything else we do. Yet few of us living in modern cities are conscious of the process. Food arrives on our plates as if by magic, and we rarely stop to wonder how it might have got there.

Improving the effectiveness of nutritional information policies : assessment of unconscious pleasure mechanisms involved in food-choice decisions
3 novembre 2021, par Mathilde COUDRAYThe rise in obesity in many countries has led to the emergence of nutritional information policies that aim to change people’s diets. Changing an individual’s diet is an ambitious goal, since numerous factors influence a person’s food-choice decisions, many of which are made unconsciously. These frequently subconscious processes should not be underestimated in food-choice behavior, as they play a major role in food diet composition. In this review, research in cognitive experimental psychology and neuroscience provides the basis for a critical analysis of the role of pleasure in eating behaviors. An assessment of the main characteristics of nutritional policies is provided, followed by recent findings showing that food choices are guided primarily by automatic emotional processes. Neuroimaging and behavioral studies, which provide new insights into the relationships between emotions and food both in lean persons and in persons with eating disorders, are reported as well. Lastly, the argument is presented that future nutritional policies can be more effective if they associate healthy food with eating pleasure.
