Food Systems Dashboard / Food Systems Types
26 octobre 2021, par Mathilde COUDRAYThe food system is all of the people and activities that play a part in growing, transporting, supplying, and, ultimately, eating food. These processes also involve elements that often go unseen, such as food preferences and resource investments.
Food systems influence diets by determining what kinds of foods are produced. They also influence what foods people want to eat and are able to access.
The different parts of the food system include food supply chains, food environments, individual factors, and consumer behavior, as well as external drivers (factors that push or pull at the system). These different parts shape food systems and can lead to both positive and negative outcomes.

Ultra-processed products are becoming dominant in the global food system
26 octobre 2021, par Mathilde COUDRAYThe relationship between the global food system and the worldwide rapid increase of obesity and related diseases is not yet well understood. A reason is that the full impact of industrialized food processing on dietary patterns, including the environments of eating and drinking, remains overlooked and underestimated. Many forms of food processing are beneficial. But what is identified and defined here as ultra-processing, a type of process that has become increasingly dominant, at first in high-income countries, and now in middle-income countries, creates attractive, hyper-palatable, cheap, ready-to-consume food products that are characteristically energy-dense, fatty, sugary or salty and generally obesogenic. In this study, the scale of change in purchase and sales of ultra-processed products is examined and the context and implications are discussed. Data come from 79 high- and middle-income countries, with special attention to Canada and Brazil. Results show that ultra-processed products dominate the food supplies of high-income countries, and that their consumption is now rapidly increasing in middle-income countries. It is proposed here that the main driving force now shaping the global food system is transnational food manufacturing, retailing and fast food service corporations whose businesses are based on very profitable, heavily promoted ultra-processed products, many in snack form.

Resource over-exploitation and running out
3 novembre 2021, par Mathilde COUDRAYFood systems around the world are highly dependent on both renewable and nonrenewable resources. Drivers such as population growth, urbanisation and climate change put a lot of pressure on resources that have become core issues for the future of food systems. Cropland availability is limited in most parts of the world, adding pressure for cropping intensification. Fossil energy and phosphorus shortages are expected to occur within a few decades, with particular impact in Low-Income (LI) countries where farmers are more vulnerable to volatile prices. The availability of very unevenly distributed freshwater resources shows a similar picture, with an increasing number of regions reaching alarming levels of water scarcity. Some world fish stocks have been overexploited and are now depleted. But the situation is not without hope. While we need to intensify food systems to meet the challenge of a growing population, new ways to produce with less impact on the environment and more resilience to climate change need to be widely adopted.

Food aid after fifty years : recasting its role
3 novembre 2021, par Mathilde COUDRAYThis book analyzes the impact food aid programmes have had over the past fifty years, assessing the current situation as well as future prospects. Issues such as political expediency, the impact of international trade and exchange rates are put under the microscope to provide the reader with a greater understanding of this important subject matter. This book will prove vital to students of development economics and development studies and those working in the field.

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.
