A dialogue between a proud omnivore (Cruciani) and a vegetarian (Innocenzi), starting from the book written by the latter, Tritacarne. Perché ciò che mangiamo può salvare la nostra vita. E il nostro mondo (Rizzoli, 2017) (Meat grinders. Why what we eat can save our lives. And our world). A reportage about Italian farms and abattoirs, about the initial part of the food production process which then ends up on our dinner tables. What is the real cost of the food that we eat? Are we willing to give up our food preferences in favour of healthier eating habits?
