Omega-3 fatty acids have some benefits, but mostly are bad PART 1
Cell membranes contain lipids, and the vulnerability of these membrane towards the damage produced by free radicals is direct connected to the degree of unsaturation of the lipids entering their constitution. Free radicals attacks double link from the fatty acids chain, and arachidonic acid enriched cell membranes, eicosapentaenoic and docosahexaenoic acid, are most likely towards oxidative lesions.
Consuming omega-3 fatty acids as fish or fish oil, raised questions about the risk of oxidative damage.
Old bodies, as well as new borns, presents a greater susceptibility towards lipid peroxidation. New-borns are very sensitive towards polyunsaturated fatty acids effects, which in lack of adequate amounts of antioxidants (e.g. tocopherol), determine the erythrocyte hemolysis. To immature new borns antioxidant systems are deficient, that when they are fed with large quantities of omega-3 fatty acids, can cause damage to the lungs, eyes and erythrocytes damage produced by oxygen. Such injuries have been observed in eskimos new borns. In the emergence of these phenomena, a diet rich in omega-3 fatty acids and poor in vegetable plays a role.
Nutrition Research Institute in the Netherlands has observed that in rats fish oil causes precancerous changes to the pancreas.
In a study conducted over 6.1 years in Finland, on 21 930 smokers men, aged between 50 and 69 years, could not prove the supposed protective effect of polyunsaturated fatty acids and omega-3 acids against coronary heart disease. Adding fish into diet can only harm the total vegetarian diet, regardless if the person is smoker or nonsmoker.
In the medical literature is claimed that omega-3 fatty acids have a beneficial effect in rheumatoid arthritis and other joint damage inflammation, psoriasis, ulcer disease and ulcerative colitis. Omega-3 fatty acids are required in optimal brain development and the eyes of newborns. Breast milk has sufficient quantities of omega-3 fatty acids instead of cow’s milk and the products on the market does not contain omega-3 fatty acids. This might be the reason why children who were breast-fed have slightly better results on tests of intelligence than those fed with cow milk.
With this information regarding the benefits of omega-3 fatty acids, the question of whether we need to consume fish, at least in small amounts, has point.
Before giving the answer, we have to examine the other face of the coin.
First, fish oil capsules and the other forms might NOT offer the benefits of fresh fish oil, natural. Although polyunsaturated omega-3 fatty acids tends to decrease the platelet aggregation and coronary disease risk, if they are oxidised, those same omega-3 acids have an opposite effect. On the stores shelves, fish oil oxidizes, and the oxidized cholesterol injures the arteries endothelium. In addition, the eicosapentaenoic acid, which is found in fish, oxidizes quickly, to form peroxides, which are strong free radicals. For those want to avoid free radicals, due to which get degenerative injuries and aging processes, quitting fish is the only logical step. Nutrition Committee of the Cardiology American Association claims that “at the moment, fish oil capsules can not be recommended for the prevention of coronary heart disease. “
