The ALA omega-3 in flax and other plants (chia, hemp, etc.) pales in comparison to EPA and DHA omega-3 from fatty fish, other seafood, algae, pasture raised meat and cheese. The body converts plants ALA fats to EPA and the process is highly inefficient. The fat is still stored or burned for energy, it just doesn't have the omega-3 health benefits.
