Yes, roots are a very important food for hunter-gatherers as Cordain published in April AJCN, but didn't focus on. Organ meats are the other improtant food, but I wouldn't go for grain fed liver only pasture fed. My real aim is to identify "stroon" which is my word for the real plant food(s) that we evolved on. [Sci-fi buffs may recognise stroon as coming from Cordwainer Smith's Norstrilia series- stroon was the most expensive substance in the universe- it was a drug that gave indefinte lifespan- it was a virus made in mutated sheep on Norstrilia- a planet founded by farmers from old Northern Australia. Smith was the pen-name of the US ambassador to Australia- his works are witty and full of cryptic satire, I loved reading them] Melissa Darby has proposed that Sagittaria latifolia may have been a major food component in our prehistoric diet: http://maelstrom.stjohns.edu/CGI/wa.exe?A2=ind0007&L=paleodiet&F=&S=&P=670 http://maelstrom.stjohns.edu/CGI/wa.exe?A2=ind0007&L=paleodiet&F=&S=&P=146 perhaps this is stroon???? Again the problems of watery sites having few archeological remnants occurs- made worse by plant foods leaving little evidence behind. Ben Balzer > Roots and tuber seem a good savannah tip.
