Pizza is thought to have been created over 1,000 years ago in Italy.

(Of course it’s now a worldwide phenomenon. In fact, the pizza effect is a term used to describe how elements of a nation or people’s culture can be transformed or at least more fully embraced elsewhere, then re-imported back to their culture of origin.

Some aspects of the change are not really something to celebrate though. For example, in the UK Pizza Hut created the Cheeseburger crust pizza with a staggering 2,880 calories. Whilst in New York the 24k pizza has been created with gold leaf, caviar, stilton cheese and truffles, a bargain at £1,600.  (It’s gone up since its invention in 2012.))

Some people will buy into anything.)
