A new study in Public Health Nutrition analyzed the corporate political activity (CPA) of major food industry actors in France. The analysis shows that the main practices used by Coca-Cola and McDonald’s were the framing of diet and public health issues in ways favorable to the company, and their involvement in the community. The French National Association of Agribusiness Industries primarily used the ‘information and messaging’ strategy (e.g. by promoting deregulation and shaping the evidence base on diet- and public health-related issues), as well as the ‘policy substitution’ strategy. Nestlé framed diet and public health issues and shaped the evidence based on diet- and public health-related issues. Carrefour particularly sought involvement in the community. The authors found that, in 2015, the food industry in France was using CPA practices that were also used by other industries in the past, such as the tobacco and alcohol industries. Because most, if not all, of these practices proved detrimental to public health when used by the tobacco industry, we propose that the precautionary principle should guide decisions when engaging or interacting with the food industry.
