Children often grow up in obesogenic environments that promote unhealthy diets. Consequently, many European children are overweight. Vending machines (that usually distribute foods rich in fat, sugar, salt and calories) located in schools are one factor that contributes to this. The aim of the pilot project “A vending machine for a friend" of the Italian Society for Cardiovascular Prevention (SIPREC) in collaboration with the Lithuanian Heart Association (LHA) and under the aegis and sponsorship of the European Heart Network (EHN), has been to regulate and improve the nutritional quality of food and beverages served in vending machines, cafeterias and school canteens. In the pilot project were included 3 Italian and 2 Lithuanian high schools. Seventy-eight Italian students and seventy-eight Lithuanian students in the 2<sup>nd</sup> and 3<sup>rd</sup> year of high school, joined the intervention group, undertaking to consume only foods and beverages from “healthy” vending machines and healthy snacks in the cafeteria, versus seventy-seven Italian students and ninety-seven Lithuanian students in the 2<sup>nd</sup> and 3<sup>rd</sup> year of high school who were part of the control group. The intervention has also included an education and training program on healthy food dedicated to the students and to the teachers. The results of the Body Mass Index (BMI) in the intervention group (-2.1% in the Italian intervention group versus +0.0% in the control group and -2.2% in the Lithuanian intervention group versus +0.5% in the control group), and of the questionnaire administered after the seminars (+53.4% of improvement in the Italian intervention group versus just +2,5% in the control group, and +21.6% of improvement in the Lithuanian intervention group versus +3% in the control group), indicates the good results achieved by the students who have participated in the project. “Healthy” vending machines together with educational programs might be a good strategy for creation of a healthy nutritional environment in high schools to tackle overweight and obesity in adolescents. Bigger studies are needed to prove concept.
