The Spanish Ministry of Health, in November 2018, notified the officially adoption of the front-of-pack nutrition label Nutri-Score which will allow consumers to easily judge the nutritional quality of food at the time of purchase and to encourage industrialists to improve the nutritional composition of food. This article synthesizes the scientific work pertaining to the validation of the nutritional profile that underlies the computation of Nutri-Score and works that demonstrate its effectiveness and superiority in comparison to other existing logos or proposed by food companies. Likewise, it highlights its development in Spain and within the European Union and responds to the fake-news raised by its detractors. It also introduces the European Citizens' Initiative to make it compulsory in Europe.
