"Speculation is that they were fed a very sweet diet to fatten them up for the sport and feasting."

Fascinating.
Some research says farmers were less healthy and lived less long than hunters. http://www.beyondveg.com/nicholson-w/angel-1984/angel-1984-1a.shtml
I wonder if eating fat pigs rather than wild lean ones might be a factor?

So what did they feed the piggies on to get them like that? My bet is sheeps milk and yoghurt and cheese.
