Flax Seeds (Ground) Nutrition Facts

Flax seeds (or linseeds) are the richest plant source of omega-3 ALA fatty acids. Ground flax is recommended over whole seeds for nutrient absorption, as the tough outer shell passes through undigested. They contain lignans with powerful antioxidant and estrogenic properties.

Should I eat whole or ground flax seeds?
