My wife uses flax-seed oil as a supplement. I figure why not buy flax seed and add it to my cereal at much less cost and perhaps more fiber. But, she says, the seed are not being digested so I'm missing the benefit. Perhaps it would help if I ground them a bit with a mortar and pestle?
Your question is a good one and your wife is correct. The hull of flax seeds is really tough and essentially undigestible. As such the wonderful oil that's inside can't get out unless you crush them first. A mortar and pestle is perfect. Crush those little guys and sprinkle them on your cereal and you're good to go.
Here's a great suggestion from one of our readers. Thanks to the Weber family for this great idea!:
I just finished one of your articles concerning the use of flax seeds. The concern of digestion of the seed was asked. To make it simple we use a coffee grinder daily to grind the seeds. This is then added to a juice and taken daily. A great natural.

In your column about flax seed, you said that it must be crushed to be digestible. I buy Hodgson Mill flax that is already crushed or milled. After I open the box I store it in the refrigerator. This is more convenient than grinding the whole seed yourself. But, is it as nutritious? Chia seed does not require refrigeration and I eat some whole or crush in a blender.
To answer your question, Ron, this is a fantastic idea. Chia seed is a great choice and just as nutritious. Refrigeration for both items is a good idea because it does prolong shelf life.
Thanks for writing,
