Hi Philip:

Bears eat grasses and they are certainly not ruminants. However I believe 
they eat the very tender young sedges that come up in the spring mostly. We 
can eat these too probably -  if we really needed to (in lean times).

I also said grass ("We don't have the multiple stomachs that grazing animals
have to digest grasses"). My adding information about the seeds of grain
grasses does not negate what I said about grass. Ruminants eat grass and
reportedly need their multiple stomachs to digest the grass. Humans don't
have multiple stomachs and don't have a rumen like ruminants do, so we don't
have the equipment that is supposed to enable digestion of grasses.
