With the aim of preventing malnutrition, it has been proposed to provide information to consumers about the nutritional content of food using labelling on packages to promote healthier eating habits. Since the way in which the consumer uses the information available in the choice of healthy foods is not clear, this article aims to analyze the interrelationship between the different types of interpretative FOP labelling and the characteristics of consumers in the food purchase intention. Food purchase intention, or its negation, is determined by different combination of conditions were perceived healthiness plays an important role. Nutrition summary indicator labelling interacts with the nutrient-specific nutritional labelling, nutrition consciousness, perceived healthiness, age, and gender in different ways to determine purchase intention or negation of purchase intention. Governments must make additional efforts to ensure that the Nutri-Score guides citizens in making healthy food choices.
