Fun but it is Ottoman/modern.  
 
Years ago when we were working in Turkey with all the archaeobotanists we  
started tracing when the South American foods arrived there - from Spain via 
 North Africa.  The earliest we found was 1581 (Busbeq's trip to  Amasia).  
I also heard from Colin Leakey (who among other things  advised Heinz about 
beans) that beans probably reached the west across  Asia.
 
I would love to hear what the latest data is on all this. 
 
I tried with Sibby Postgate to reconstruct the Bronze Age  diet in a 
diagram based on an advert for olive oil margarine lauding  the Mediterranean 
diet. We got it as accurate as we could in 2002.  I  can send it to anyone who 
would like it as a pdf attachmet..
