There are several significant nutritional components in flax seed that are beneficial to our health including Omega-3 oils, flax hull lignans (SDG), and fiber.
A number of medical studies suggest a wide range of health benefits of Flax Seed components (especially flax hull lignans and Omego 3 oils) such as
Wow - Quite a List! And did you know that flax seed is the richest source of Omega-3? Omega-3 is not an optional nutrient. Our body needs it to survive. Unfortunately Omega-3 is one nutrient our body cannot manufacture; it looks to outside sources to get Omega-3. The good news is that many of the health foods we consume, such as broccoli, have Omega-3. The bad news is it would take eating pounds instead of just ounces of some of our favorite foods to get a healthy dose of Omega-3 in our diet.
No need to panic! Our miraculous little seed offers us 48% of its total fat content as Omega-3 fatty acids. This is even better than the other well-known source of Omega-3, fish oil. However, I hope you are a fish lover because to get the same amount of Omega-3 in about a half cup of ground flax seed you would have to eat about 1 pound of fish. Too bad fish does not taste well blended into baked products, yogurt, or other snack items.
Flax Seed is the richest known source of lignans, with 100 to 800 times the level of lignans found in other oil seeds, cereals, and legumes. Plant lignans are metabolized in the colon by bacterial fermentation. The lignan metabolites, which have a strong antioxidant activity, appear to be anticarcinogenic. They have structure similar to estrogens and can bind to estrogen receptors, thereby inhibiting the growth of breast cancer. Lignans may also produce positive effects in women with ovarian dysfunction.
