pasta has only been on the menu since it came back from china about 500 years ago, and tomatoes, capsicum, etc... yeah, 400 years since they arrived
what the romans ate was a lot different
and it's not for nothing the cliche of the fat italian man with the pizza
having said that, the old italian houses with the hot stone wood fired ovens are amazing ways to cook pizza
it's just not healthy for humans to eat more than about 10% of their diet based on grains, a little is ok but the USDA food pyramid is upside down... fats... protein... fruit and veg, and then grains is the right priority ordering
