Foodinsider is a network of people with difference competence that have in common the interest in the quality of food, and healthy and sustainable diet. Foodinsider was born in 2015 as an initiative of School Canteen Committees that in Italy are present in many Italian cities and are formed by parents and teachers on a voluntary basis every school year. The task of the School canteen Committee is to monitor the quality of food and service by supervising school meals, tasting the food and filling reports. As an example, in Milan, there are currently 2.200 commissioners operating at school. Starting from 2011, the Milanese School Canteen Committees began to elect their own representatives (2 for each city zone, so 18 in total), a team of people who have managed to negotiate improvements of menus and service. Claudia Paltrinieri, founder of Foodinsider, was a member of the first elected Representation of the School Canteen Committees, which ran for four years (2011-2015). She later launched Foodinsider, a digital platform devoted to food education with a focus on school canteen menus. The original aim was to share information among parents and provide tools to increase their awareness about the quality of the menus. The Score Menu was a test employed by school canteen committee representatives to assess school menus. By answering the questions, parents could calculate a total score for their school canteen menu, which showed them the quality level of the service. This assessment system was taken as the core element of Foodinsider digital platform. The test was filled by many people and the data gathered gave a clear picture of the current situation of school canteen service. The first Rating was published in 2016, then a second Rating followed in 2017 and a 3rd Rating has been supported by a newly-established scientific committee. The aim of the 2019 Rating is to underline the most frequent mistakes in the school meals related to health and sustainability, according to the SDG objectives (the number twelve: responsible production and consumption). Thanks to the National Rating program, Foodinsider opened a national-scale debate about school canteen service, firmly grounded on objective data, and allowed people to make comparisons among different catering models and highlight the best menus and the best models according to health and sustainability.
