Flax seed, also known as linseed, is noted to have high nutritional value. In particular, flax seeds contain a high content of alpha-linolenic fatty acids (an essential omega-3 fatty acid) and fibre. In fact, more than 70% of fat in flax is of the healthful polyunsaturated type. A unique feature of flax is the high ratio of alpha-linolenic acid (an omega-3 fatty acid) to linoleic acid (an omega-6 fatty acids)
