Many diets eschew flax seed in general, but something to keep in mind is that unground flax seed itself is a good source of fiber. Mind, I'm not saying it's the best source of EFA's, but it's far better than junk food or fast food. I typically will put a very large spoonful of flax seed into about 3/4cp of Greek yogurt and add a little honey for a tasty treat, but I do also supplement with fish oil pills. I'll also add glazed walnuts to a bowl of plain old oatmeal for a filling and healthy breakfast.
