Wellness with Omega-3 and omega-6 fatty acids anti aging
Omega-3 and omega-6 fatty acids are essential for health and well-being stay young, anti aging.
Wellness with Omega-3 and omega-6 fatty acids anti aging:
Among the various lipids of nutritional interest, two deserve special attention. It is polyunsaturated fatty acids, respectively called linoleic acid or LA (18:2) and alpha-linolenic acid or ALA (18:3). These fatty acids are called essential (or AGEs), since, given the inability of the organism to synthesize them, they must be obtained from the diet.omega-3 and omega-6Una once recruited through food, these two nutrients are converted by an enzyme in other polyunsaturated fatty acids (PUFA). In particular, the linoleic acid is the parent fatty acid of the omega-6 series, while starting from alpha-linolenic acid are obtained analogues of the omega-3 series. These metabolic pathways involving the intervention of two enzyme complexes, capable of lengthening the carbon chain (elongase) and to increase the number of double bonds (desaturase).Thanks to these measures enzymatic form the respective series of fatty acids, belonging to the omega-6 series, if derived from linoleic acid, and the omega-3 series, if they originate from alpha-linolenic acid.
Wellness with Omega-3 and omega-6 fatty acids anti aging: A curiosity: the terms “omega-6” and “omega-3” refer to the position of the first double bond with respect to portion methyl (terminal) of the molecule, is therefore not a case that falls in their nomenclature the symbol omega, which represents the last letter of the greek. So in the omega-6 the first double bond is between the sixth and seventh carbon atom from the methyl group; in omega-3, however, between the third and the fourth carbon, always starting from the methyl end.The symbology (xx: x) indicates the number of carbon atoms of the fatty acid compared to the number of double bonds of the molecule, for example, linoleic acid (18:2) consists of 18 carbon atoms and has two double ties (see figure).The main derivatives omega-6 linoleic acid are: the gamma-linolenic acid or GLA (18:3), l ‘Diomo-gamma-linoleic acid or DGLA (20:3) and arachidonic acid (AA, 20 : 4)In addition to being synthesized in the body, these fatty acids may be engaged with the power supply. Good sources of omega-6 seed oils, nuts and legumes. sardineI main omega-3 derived omega-3, originated from the metabolism of alpha-linolenic acid, are: eicosapentaenoic acid or EPA (20:5) and docosahexaenoic acid or DHA (22:6). The best food sources of omega-3 are cold-water fish, olive oil and flaxseed. Wellness with Omega-3 and omega-6 fatty acids anti aging: The body’s ability to synthesize derivatives omega-6 and omega-3, like many other biological functions, tends to decline with advancing age.
It ‘also important to remember that omega-6 and omega-3 compete for the use of the enzymes involved in their desaturation (desaturase), as common to both pathways. Consequently, an excessive intake of omega-6 may impair the formation of omega-3 starting from alpha-linolenic acid, and vice versa.Not surprisingly, in the typical diet in Western countries, the omega-6/omega-3 ratio is 10:1, while, to be perfect, it should be 6:1.To balance this relationship is vital to increase the consumption of fish, especially the blue and the species that inhabit the northern seas.
Finally, the fatty acids of omega-6 and omega-3 are the precursors of eicosanoids, which became famous for the studies of Dr. Barry Sears and its famous food model, called the Diet in the area. Without going into details insidious biochemists, ecosanoids are locally acting hormones or paracrine (prostaglandins, thromboxanes and leukotrienes) that regulate various functions and physiological parameters.

The levels and the balance of the two series of fatty acids seem to be important for the prevention and treatment of coronary heart disease, hypertension, type 2 diabetes, inflammatory and immune disorders. Functions of omega-6 and omega-3 The omega-6 polyunsaturated fatty acids lower serum cholesterol, reducing the plasma levels of LDL. This benefit, however, is partly mitigated by the fact that the same omega-6 fatty acids also reduce the “good” cholesterol HDL.
The oleic acid (olive oil), however, reduces the levels of LDL-cholesterol without affecting the percentage of HDL-cholesterol. This fatty acid, although not essential as the other two, is therefore very important to our well being. The oleic acid is found in numerous dressings of vegetable origin, and particularly in the olive oil that, also for this reason, is one of the best seasonings for use in the kitchen. Wellness with Omega-3 and omega-6 fatty acids anti aging: The omega-3 polyunsaturated fatty acids lower plasma levels of triglycerides, interfering with their incorporation into VLDL in the liver. For this reason possess an important antithrombotic action (remember, in fact, that high levels of triglycerides in the blood reduces the process of fibrinolysis, deputy to the melting of intravascular clots and for this reason the hypertriglyceridemia is accompanied by an increased risk of cardiovascular disease) .
All this explains why every day, through television and newspapers, doctors and nutritionists stress the importance of regular consumption of foods rich in omega-three (fish and flaxseed), in order to control the blood cholesterol levels , triglycerides, and, together with them, the risk of cardiovascular disease.You can find more articles, with tips and details on our beauty and wellness category.
