Ground Flaxseed (Flax Meal): How Many Grams in a Cup?

Flaxseeds must be ground for your body to absorb their nutrients, but grinding changes their volume drastically. A cup of whole seeds does not equal a cup of ground meal. In vegan baking (flax eggs) or keto recipes, gram-level precision is vital for the binding chemistry to work.

FAQ

Can I buy pre-ground flaxseed?
Yes, but it oxidizes (goes rancid) quickly due to the oils. It is best to buy whole seeds and grind/weigh them as needed, or store bought meal in the freezer.
