Flax Seeds are high in Omega3 Fatty acids. Whole Flax seeds are not digested and hence you need to grind it to be consumed. The ground flax seed becomes oxidized if kept exposed to air for long time. So it should be ground freshly at home. You can use a coffee grinder or the chutney jar of the mixer to grind it. It lasts upto 30 days when stored in an air tight jar.
