IntroductionIn November 2010 the Mediterranean Diet was recognized by the UNESCO as Intangible Cultural Heritage of Humanity. It is an heritage that brings together the dietary habits of the peoples of the Mediterranean countries, consolidated over the centuries remained almost unchanged until the 1950s. Numerous scientific studies have also shown that the Mediterranean Diet is an healthy diet that helps to prevent the main chronic diseases such as cardiovascular diseases, diabetes, bulimia and obesity and thanks to the antioxidant power of olive oil combined with vegetables consumption, an important means of cancer prevention. The aim of our study was to investigate the knowledge and the adherence to the Mediterranean diet of young people living in the Mediterranean area. Materials and methodsThe survey was carried out by administering a web-based anonymous questionnaire from March to May 2019 to Italian young people. In this survey we asked for socio-economic conditions, knowledge, awareness and adherence to the Mediterranean diet (through the KIDMED test) both in childhood and at present time. Parental educational status and family income were used as indicators of socio-economic status (SES). ResultsThe sample was made up by 507 Italian young people between the ages of 17 and 35 (123 males and 384 females), with an average age of 22.88 years (DS 7.02). Only 11.4% knew the Mediterranean diet. During childhood 70.8% of respondents had breakfast and 58% ate fruit and vegetables daily. Today they have maintained the correct eating habits, in fact, 71.2% had breakfast, 60.2% ate fruit and 64.7% ate vegetables. In addition, only 48.3% eat fish and the majority of respondents consume carbohydrates (76.9%). To a lesser extent they consume junk foods like candy and various snacks (18.1%) or fast food meals (9.1%). Moreover, we asked for physical activity and we found that 48.9% did it. We found age, exercise and sex high significant variables (p<0.01). Higher adherence to MD was found in older interviewees. ConclusionsOur study we found high knowledge to a Mediterranean diet into 90.5% of the sample and poor adherence into 23.5% of them, medium into 53.4% while higher only in 23.1% of the interviewees.  Lower adherence was found among those who do not engage in physical activity and the two regressor with higher weight on the adherence to MD were “eat at home “and “eat fruit and vegetables”. Furthermore, in our sample more increased the age more increased adherence to traditional diet models.
