Strictly speaking, Flax is not a grain. Grains are from grasses, like
rice, wheat, barley, etc. Flax is a tall woody plant with a blue flower.
Its fibers are used to make linen. The seeds are highly nutritious. I
don't see where flaxseed could be off the list. After all, wouldn't
Paleobabe be grinding the seeds with her rocks?
