Flax is an amazingly useful plant. Flax seeds and flax seed oil are a great source of alpha linolenic acid, or LNA.It is a small herb (Linum usitatissimum) grown in the prairies of North America and Russia, with little five-petaled blue (sometimes white or pink) flowers. The plants are harvested when the seed pods have dried and the fibers of the inner stems are processed to make thread for linen. This process dates back to ancient Egypt. Each cell membrane structure in the brain includes two components, which also help control nutrient transfer in and out of brain cells. These two components are both essential polyunsaturated fatty acids: alpha linolenic acid (LNA, one of the omega-3 fatty acids) and linoleic acid (LA, one of the omega-6 fatty acids). LNA is used by the body to make DHA, or docasahexaenoic acid. Nursing mothers can be assured human milk contains DHA in perfect amounts. Adults and older children need to obtain it from other sources (cold water oily fish like salmon and tuna), or manufacture it from LNA. Omega-3s are like, well, antifreeze for our bodies. They keep our blood relatively thin and circulating well, especially in cold weather. The ground flaxseed meal can be added to salads, mixed in with hot or cold cereals, or used in recipes for baked goods. One ounce of ground flaxseed meal (about four tbsp or about 60mls) provides about six grams of protein and eight grams of fiber.
