A school-based intervention to foster adherence to the Mediterranean diet in adolescents: the PROMEDLIFE project

Abstract The need to maintain the production of local foods characterized by a high nutritional index, update traditional food production methodologies by developing attractive tech-based approaches, promote healthy eating habits that meet consumers’ preferences and acceptability, as well as reducing the complexity of supply chains (Farm to Fork) must be addressed to ensure food and nutrition security. This is especially true in Mediterranean countries undergoing dietary and nutritional changes that affect their inhabitants’ health while creating many socio-economic and environmental challenges. PROMEDLIFE aims to increase adherence to the Mediterranean diet through a multi-actor approach by encouraging the adoption of a healthy eating lifestyle while decreasing the environmental and economic impact of food production and processing. It also aims to attain optimal food communication and education through training programs that target primary and secondary students as well as their families, from children to older adults. A 4-week nutritional and sensory educational intervention in high school students involves frontal lessons, a web-app for families enrolled, and games on nutrients, food groups, balanced meals and various eating occasions, healthy and sustainable diets. In addition, adherence to the Mediterranean diet, nutritional knowledge, sociodemographic and lifestyle data, picky eating, and food neophobia are investigated. Including nutritional lectures in the school curriculum of high schools promotes knowledge acquisition about healthy diet. However, a period longer than 4 weeks may be necessary to translate this knowledge into improved eating habits. The project is still ongoing, and follow-up data collection will be performed. Final analysis, including data on picky eating and food neophobia, as well as overall eating behavior at follow-up, will allow an evaluation of possible long-term changes.
