Sure, but by eating animals (including insects, organ meat, etc.), paleo
peoples used the animals to concentrate the EFAs in their fat. Eating flax
is a poor substitute perhaps for this, but all we can do is eat analogously
anyway. It is perhaps a reasonable way to get EFAs with today's factory
farmed animals.
