Flaxseed is inexpensive and you should be able to find it at your local health food store. Keep in mind that if the seeds aren't crushed, ground, or broken, they will pass through your system intact and you'll lose the benefits. Except for decorating the outside of bread loaves or muffins, I would recommend grinding the seeds in a small food processor or a blender. Small, inexpensive coffee grinders also work well for this purpose. (If you intend to use a blender, adding a bit of water or liquid to the seeds will make the blending process much easier.)
When using a coffee grinder to grind flaxseeds, is it also advised to add some water to the seeds? Or will adding some water cause danger and damage to the coffee grinder due to short circuit caused by water?
