The virtues of consuming flax seed are much-extolled, but many people don't realize that you can't get any nutritional benefit from eating the seeds whole (they simply pass through your system).  You could ground the flax seeds yourself, or you can buy a great product like this one by Spectrum.  Ground flax is a wonderful addition to your diet--just 2 TB adds protein (3g), fiber (3g), and healthy fats.  Plus, flax has a delicious nutty taste that is perfect on cereal, yogurt, salads, or even as a filler in things like meatloaf.  Finally, if you store it in the freezer, it will keep for months--highly recommended!
