Use Your (Paleo) Loaf

So how about this from CBS?  Stone Age Menu Featured Flour From Wild Grains.  Stone Age man made flour - perhaps as much as 30,000 years ago.  Now before some of the major bread manufacturers jump on the paleo bandwagon I guess we should point out to them the following:

• As Paracelsus observed, 'Alle Ding' sind Gift, und nichts ohn' Gift; allein die Dosis macht, daß ein Ding kein Gift ist. ' - "the dose makes the poison".
• Grains would be seasonally available.  "Paleo" does not mandate year-round fruit consumption either.
• Cannabis seeds were apparently eaten in China around 6000 BC.  To all bread manufacturers, I will await your "Paleo Bread with Added Cannabis Seeds" with interest.
• HG didn't eat much if any wheat.  There is no evidence it was present or even dominated the ingredients of their bread.
• Whilst having an emergency ration of paleo flour might get you through a hungry period, this would be impractical in politically unstable times and a burden during winter (can you imagine carrying a bag of flour on a hunt?), or in times of abundance.

From the article,

• "The team led by Anna Revedin of the Italian Institute of Prehistory and Early History in Florence found grinding stones, similar to a stone and pestle, with remains of grains at the sites.
  
  The three sites were all dated to about 30,000 years ago and the residues appear to originate mainly from cattails and ferns, which are rich in starch and would have provided a good source of carbohydrates and energy."

Nice of CBS to opine that far from an all meat diet, the HG diet was 'more balanced after all'.  Notwithstanding how much significance flour had on their diet, I wonder if there is any evidence as to the health of those HGs who tended to this 'diet'?  In 30,000 years from now, if it could be determined by similarly remote evidence what we ate in the West in abundance (O6, fructose and sugar), could those same investigators determine our poverty of health?

From my understanding I wonder if flour was actually used as a 'social drug' like cannabis?
