Flax seeds are small seeds that are used to produce linseed oil used in paint, varnish, ink and linoleum. But they're good for you, too. Flax seeds contain alpha-linolenic acid, which can be transformed into omega-3 fatty acid in the body. Flax seeds also contain essential nutrients like calcium, iron, niacin, phosphorous and vitamin E.

Flax seeds have a subtle nutty flavor and can be sprinkled onto cereal or other dishes as well as sprouted and added to sandwiches or salads. Ground into flour and mixed with three parts liquid, they can act as a stand-in for egg whites in baked goods.

Depending on your stomach, flax seeds may aid digestion or have a laxative effect.
