The rapid rate of postmenopausal bone loss is mediated by the inflammatory cytokines interleukin-1, interleukin-6, and tumor necrosis factor alpha. Dietary supplementation with flaxseeds and flaxseed oil in animals and healthy humans significantly reduces cytokine production while concomitantly increasing calcium absorption, bone calcium, and bone density. Possibilities may exist for the therapeutic use of the omega-3 fatty acids, as supplements or in the diet, to blunt the increase of the inflammatory bone resorbing cytokines produced in the early postmenopausal years, in order to slow the rapid rate of postmenopausal bone loss. Evidence also points to the possible benefit of gamma-linolenic acid in preserving bone density. (Kettler D, Altern Med Rev, 6(1): 61, 2001)
Results of many studies indicate that consumption of n-3 fatty acids can benefit persons with cardiovascular disease and rheumatoid arthritis. However, encapsulated fish oil is unlikely to be suited to lifetime daily use and recommendations to increase fish intake have not been effective. Foods naturally rich in n-3 fatty acids, such as flaxseed meal can be used to achieve desired biochemical effects without the ingestion of supplements or a change in dietary habits. A wide range of n-3-enriched foods could be developed on the basis of the therapeutic and disease-preventive effects of n-3 fatty acids. (Mantzioris E, et al, Am J Clin Nutr, 72(1): 42, 2000)
Many anti-inflammatory pharmaceuticals inhibit the production of eicosanoids and cytokines and it is here that possibilities exist for n-3 dietary fatty acids. Flaxseed oil contains n-3 fatty acid alpha-linolenic acid which can be converted after ingestion to eicosapentaenoic acid (EPA), which can act as a competitive inhibitor of AA conversion to PGE(2) and LTB(4), and decreased synthesis of these is observed after inclusion of flaxseed oil in the diet. Regarding the pro-inflammatory cytokines, tumor necrosis factor alpha and interleukins 1 beta, studies of healthy volunteers and rheumatoid arthritis patients have shown 90% inhibition of cytokine production after dietary flaxseed oil. (James M, et al, Am J Clin Nutr, 71(1 Suppl): 343S, 2000 )
It is essential in the process of returning n-3 fatty acids into the food supply that the balance of n-6/n-3 fatty acids in the diet that existed during evolution is maintained. Clinical investigations confirm the importance of n-3 fatty acids for normal function during growth and development and in the modulation of chronic diseases. Pregnant and lactating women and infants should benefit since their diet is deficient in n-3 fatty acids, especially for the vegetarians among them. Since cardiovascular disease, hypertension, and autoimmune, allergic, and neurological disorders appear to respond to n-3 fatty acid supplementation, a diet balanced in n-3 and n-6 fatty acids consistent with the diet during human evolution should decrease or delay their manifestation. (Simopoulos A, Lipids, 34, Suppl, 1999)
Human beings evolved consuming a diet that contained about equal amounts of n-3 and n-6 essential fatty acids. Over the past 100-150 years there has been an enormous increase in the consumption of n-6 fatty acids due to the increased intake of vegetable oils. Today, in Western diets, the ratio of n-6 to n-3 fatty acids ranges from approximately 20-30:1 instead of the traditional range of 1-2:1. Studies indicate that a high intake of n-6 fatty acids shifts the physiologic state to one that is prothrombotic and pro-aggregatory, characterized by increases in blood viscosity, vasospasm, and vasoconstriction and decreases in bleeding time. n-3 Fatty acids, however, have antiinflammatory, antithrombotic, antiarrhythmic, hypolipidemic, and vasodilatory properties. These beneficial effects of n-3 fatty acids have been shown in the secondary prevention of coronary heart disease, hypertension, type 2 diabetes, and, in some patients with renal disease, rheumatoid arthritis, ulcerative colitis, Crohn disease, and chronic obstructive pulmonary disease. Most of the studies were carried out with fish oils [eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)]. However, alpha-linolenic acid, found in green leafy vegetables (and especially) flaxseed, desaturates and elongates in the human body to EPA and DHA and by itself may have beneficial effects in health and in the control of chronic diseases. (Simopoulos A, Am J Clin Nutr, 70(3 Suppl) 1999)
Flaxseed, with 51-55% alpha-linolenic acid in its oil and its richest source of plant lignans, reduces hypercholesterolemic atherosclerosis by 46-69% without lowering serum lipids. (Prasad K, Atherosclerosis, 136(2): 367, 1998)
Use of flaxseed oil as a vegetative source of PUFA omega-3 in diet of patients with ischemic heart disease, hyperlipidemia and high blood pressure resulted in positive dynamic of clinical manifestation, blood lipids and coagulograms of the patient. Pronounced influence on membrane lipids of erythrocytes was revealed: significantly increased a quota an linolenic, eicosapentaenic and docosahexaenic PUFA against a background of reducing a level of linoleic acid. (Rozanova I, et al, Vopr Pitan, (5): 15, 1997)
The compliance or elasticity of the arterial system, an important index of circulatory function, diminishes with increasing cardiovascular risk. Dietary n-3 fatty acids in flax oil confer a novel approach to improving arterial function. (Nestel P et al, Arterioscler Thromb Vasc Biol, 17(6): 1163, 1997)
Naturally occurring polyunsaturated fatty acids (PUFA) are derived from (C18) linoleic and (alpha) linolenic acids, which cannot be synthesized by animals, but have to be derived directly or indirectly from plants. However, these acids are metabolised by animals from plants to form the omega 6 and omega 3 families of C20 and C22 PUFA and their physiologically powerful eicosanoids. The omega 6 eicosanoids generally produce such adverse effects as inflammation, clotting and promotion of cancer cell growth, and have an unfavourable influence on the immune system. In contrast, the omega 3 eicosanoids are anti-inflammatory, anti-clotting, retard the growth of cancer cells, and produce favourable effects on the immune system. The protective effects of omega 3 metabolites on coronary heart disease and cancer are relevant to the question of longevity. Polyunsaturated margarine is high in omega 6 fatty acids, and meat and milk products, high in omega 3 fatty acids, are however also high in cholesterol. (Shoreland F, Proc, Nutr Soc New Zealand, 17, CAB International, 1995) Flax bears the benefits without the risks.



mega-3 ratio [3-5]. Flaxseeds also have additional components, such as lignan precursors, which may play a role in preventing breast and other cancers [6], but these are not found in appreciable amounts in commercial flaxseed oil products.
