Is Nutri-Score working in France? The results are in… Three years ago, France adopted Nutri-Score. What impact has the nutrition labelling scheme had on purchasing behaviour? In October 2017, the French government signed a decree backing the voluntary adoption of the Nutri-Score front-of-pack (FOP) labelling scheme. The scheme ranks food from -15 for the ‘healthiest’ product to +50 for those that are ‘less healthy’. On the basis of this score, the product receives a letter with a corresponding colour code: from dark green (A) to dark red (F). At the time, French authorities said the scheme was the ‘most effective device’ to improve the quality of nutrition standards. It hoped the new FOP label would make the nutritional content of food an ‘element of food choice’, alongside price, branding, presentation, and taste.
