The book explores, through a reflection on food, the complexity of the concept of well-being. It starts from the consideration that food is a fundamental element for human well-being, and for well-being of the planet as a whole. Not only does food guarantee the survival of human beings, it is also a cultural expression. With regard to the Italian socio-cultural context, the contributors explore how food relates to aspects such as history, tradition, new food styles, health, and the old and new technologies used to produce food. The studies in the book do not simply analyse indicators to illustrate the Italian situation in the "here and now". As part of the tradition of studies on social indicators, they provide valid and well-founded indications to contribute to an improvement in the quality of life for years to come. This work on the theme of food represents a very useful contribution to the general reflection on well-being and its statistical, sociological, and multidisciplinary study, due to the importance historically given to food in Italy and the socio-cultural implications of food in various life contexts.
