Flaxseed is a popular nutritional item these days -- and for good reason. It's an excellent source of omega-3 fatty acids, dietary fiber, and substances that may help prevent breast and prostate cancer.
For the biggest nutritional punch, use the seeds themselves. Flaxseed oils do provide omega-3 fatty acids, but don't have the fiber that seeds do.
Flaxseeds are small, reddish-brown, and nutty in flavor. The simplest way to use flaxseed is to sprinkle it on top of salads, yogurts, cereals, soups and other foods. You can also mix flaxseed oil into salad dressings. Both seeds and oils should be stored in the refrigerator.
