Using Google data to measure the role of Big Food and fast food in South Africa’s obesity epidemic [06.06.21]
The change in eating habits and decline of physical activity is reflected in increasing numbers of overweight people worldwide. The few studies on the impact of changing dietary environments on obesity in low-and middle-income countries provide 'mixed' results with regard to links between food retailers, nutrition and health. Using a new methodology, Stefan Otterbach and Hamid Reza Oskorouchi from the Chair of Household and Consumer Economics and their colleagues from IZA Bonn and Rhodes University (South Africa) in a recent study analyzed the dominant influence of large food supermarkets and fast food chains on the obesity epidemic.
