Nutrition is one of the topics closest to the lives of people, as citizens because food signifies culture, identity and tradition, but also in terms of economics because nutrition is an extremely important economic sector (especially in Italy) that ranges from industrial production to catering, and from genuine local production to territorial marketing strategies. In recent years in Milan it has become even more topical thanks to the Universal Exposition 2015 to be held in the city under the title â€œFeeding the planet, energy for lifeâ€. Nutrition is thus a highly collective concept, but that is always based on strictly personal choices: what and how we eat is a choice that depends on personal taste, health, finances and knowledge. And it is of the utmost importance to spread awareness that even though we eat at least three times a day, the choices we make with regard to the food we eat are anything but trivial because they have so many implications in terms of individual and collective consequences. For this reason, the works of the European Institute of Oncology -IEO -in its information campaigns take on increasing importance for each of us as individuals and for all of us as a society. Through this book in particular, the IEO offers a global perspective on the importance of nutrition, presenting food on the one hand as a duty of care and health, and on the other, food in terms of the simple pleasure of taste. Our thanks for this volume go above all to its editor, who with elegant simplicity has given us all a great but simple lesson, which in the end is also the secret of the best of Made in Italy: learning how to put together the things we like with quality, to the benefit of the spirit as well as the body that carries it.
