Paleo Porridge

Is porridge 'paleo'?  Well it was consumed before settled agriculture (not nomadic agriculture).  From New Scientist - Stone-age people were making porridge 32,000 years ago:

• To see the benefits of a plant-based diet, you only need to know that society has been largely fuelled by processed grains for the last 20,000 years, says archaeologist Matt Pope of University College London. “There is a relationship there to be explored between diet, experimentation with processing plant food and cultural sophistication.”
  
  
  This is another example of the advances made by Europe’s Gravettian culture, which produced technology, artwork and elaborate burial systems during the Upper Palaeolithic era, says Erik Trinkaus at Washington University in St Louis, Missouri. “These people were described 15 years ago as ‘Hunters of the Golden Age’, and the details of that are still being filled out.”
  
  Mariotti Lippi’s team hopes to continue studying ancient grinding stones to find out more about the Palaeolithic plant diet. Grinding stones go back a long way, says Trinkaus, and people may well have been pounding and eating various wild grains even earlier than 32,000 years ago.

 Let's not lose sight that such grains would not have been harmongenised, of vastly differing strains to those eaten nowadays, were unlikely to have been processes to such refined, acellular state, nor covered in sweetened substances to the extent that cereals in their modern form are.  We must also consider the seasonal nature of diet and how this affects consumption rates and so forth. 

There is little to say whether such food was a food of last resort or how it was considered against game.  Perspective, people.
