Whole flaxseeds keep their outer shell intact. You might notice them adding a distinct, slightly crunchy texture to foods like salads, breads, or yogurt bowls. To get the full nutritional benefit from whole seeds, it's helpful to chew them thoroughly or soak them first, which softens them.
Grinding flaxseed (e.g., in a coffee grinder just before use) breaks the seeds open, making the internal contents like alpha‑linolenic acid and soluble fiber more readily available when consumed. It also allows the ground powder to blend evenly into foods and liquids without changing the texture much.
Whichever form you prefer, remember that ground flaxseed should be used quickly or stored airtight in the refrigerator or freezer to help keep its oils fresh.
