RESUMEN
Unhealthy dietary habits constitute a major risk factor for the onset of chronic diseases, such as cardiovascular diseases, cancer, diabetes and other conditions linked to obesity. Effective dietary changes are of paramount importance and can be promoted through empowering individuals with Nutrition Literacy (NL) and Food Literacy (FL) skills. This paper presents a novel serious game aiming at building NL and FL skills in adolescents and young adults. It is based on an innovative conceptual framework, incorporating a recipe ontology and a theory driven game design approach maximizing user attractiveness and promoting sustainable effective dietary changes. The ontological modeling of recipes offers game experience personalization while providing a realistic and diverse simulation environment. Modern game design techniques from three game genres (cooking, roguelike, puzzle) are employed along with a compelling plot for engagement purposes.
