Whole vs Ground Flax Seeds

Grinding is what actually makes flax seed's contents accessible. Whole seed largely passes through unchanged.

Whole and ground flax seed are the same seed at two different stages, and the difference between them matters more than it does with many other seeds, since whole flax largely passes through digestion unchanged.

What actually differs

  • Whole flax seed has a hard outer shell that mostly resists digestion unless chewed very thoroughly or ground beforehand.
  • Ground flax makes the seed's contents more accessible, which is why grinding is commonly recommended over eating whole seed.
  • Ground flax oxidises faster than whole seed once exposed to air, so it benefits from being ground closer to when it will be used.
  • Whole flax seed keeps longer in storage than ground, since the shell protects the contents from air and light.
  • Roasted whole seed sits between the two, offering some of ground flax's easier texture while still keeping reasonably well.

Our standards

Whole vs ground flax questions

Should I always grind flax seed before eating it?
It is generally recommended for accessing the seed's full contents, though whole roasted seed still has real value eaten as is.
Does ground flax lose value quickly?
It oxidises faster than whole seed, so grinding smaller batches more often keeps it fresher than grinding a large amount at once.
Can I buy flax seed already ground?
We sell whole seed, plain and roasted, which you can grind at home in the quantity you need.
Is roasted whole flax easier to digest than raw whole flax?
It can be slightly easier to chew and break down, though grinding still makes the biggest practical difference.
