This study evaluates the impact of the introduction of a front-of-pack nutrition label on foods and beverages sold in a campus cafeteria in France on the nutritional quality of purchases.
The introduction of front-of-package nutrition labelling is thought to help consumers making healthier food choices at the point-of-purchase.
Recently, the French government has selected the Nutri-Score as single front-of-pack nutrition label.
Evaluations of the Nutri-Score suggest it is in helping consumers making healthier choices. However, its impact in vulnerable populations has not yet been tested. Students are thought to be a vulnerable population due to their limited resources and to their unhealthy food choices.
The objective of the present study is to investigate the impact of the introduction of the Nutri-Score in campus cafeterias on the nutritional quality of food purchases. The intervention is conducted during several months, with a control period without front-of-pack nutrition labelling at the beginning of the university year.
Data on purchases is collected regularly through receipts, and the nutritional quality of purchases is evaluated over time between the intervention situation and the control situation.
