A Google search returns 117 million pages on “spaghetti” from 2004 to 2012. The search volume reported by Google Trends for queries containing “spaghetti” stems from the worldwide diffusion of pasta consumption, in particular in northern and southern America and in central and southern Europe. The globalization of spaghetti may originate from several factors, not only immigration flows and tourism, but also the soft power of Mediterranean diet (Intangible cultural heritage of Humanity, 2013).
