I did a little further digging concerning flax seed. Whole flax seed will keep in a covered jar in a dark, cool cupboard for about a year or longer. That's because it has a hard hull that preserves the goodness. When it's ground it will keep about 90 days. Whole or ground have the same nutritional content but you get more benefit from ground flax seed. That's because it's hard to crack that shiny seed. Flax seed is good for you in so many ways. Hope this helps
