Fish oils contain two long chain fatty acids, eicosapentaenoic acid (EPA) and Docosahexensäure (DHA), which influence the synthesis of prostaglandins that meet regulatory functions. Fish oils are said to have many positive effects: it is believed that they improve the overall health and help with many complaints.
These fatty acids are formed in the plankton and the seaweeds, which are the food for the fish. Because of their extremely low fixed point need plant and animal life in cold waters, these fatty acids to solidify and not to remain supple. The key to human omega-3 fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA).
The human body is due to its enzyme equipment from other in the diet fed omega-3 fatty acids, such as at the "mother substance" of the "Omega-3 fatty acid family," the alpha-linolenic acid, not always appropriate quantities DHA and EPA produced. DHA and EPA, however, urgently needed by the human body as a biochemical building for many cell structures, such as the lipid membranes all cells and known for important local mediators, which prostaglandins, leukotrienes and thromboxanes are.
These substances are ultimately responsible for whether the fluidity of the blood are favorable, or whether the strength (viscosity) of blood is increased and results in a worsening of the circulation as well as thrombosis. The importance of fish oil with its high quality DHA and EPA substances is increased by the following facts: first
The family of omega-3 fatty acids is already in the Central European and American food are rare.
second The omega-3 fatty acids (alpha-linolenic acid, DHA, EPA) compete in the human body with the omega-6 fatty acids (linoleic acid, arachidonic acid, gamma linolenic acid) for the same enzyme system.
Since in the Central European and American food in addition to the abundant and saturated fatty acids, only linoleic acid and arachidonic acid from the family of omega-6 fatty acids are supplied abundant (eg in sunflower oil, margarine, cooking oils and animal products), have the Omega -3-fatty acids hardly a chance to get back to the enzyme system for further processing: they are in the minority and not turn to come. " The consequence of this situation is that as mainly the result of products the "bad" arachidonic acid are formed, namely the leukotrienes promote the so-called 4-Series, which cause inflammation, allergies, or possibly even.
omega-3 fatty acids and fish oil in the diet of the Mediterranean, Japan and Greenland abundant. As found in these regions, heart attack and stroke less often than in Central Europe and the USA, we became aware of the omega-3 fatty acids. In the following years, the biochemists have been dealing with these substances. The discovery of the metabolism of omega-3 fatty acids and the so-called eicosanoids led 1982 Nobel Prize for Medicine.
The realization in everyday life; Core of this ground-breaking discoveries of Nobel Prize winners can be summarized as follows: Relatively easy to be implemented changes in diet can dramatically reduce the incidence of many diseases.
The intake of omega-3 fatty acids, particularly DHA and EPA in fish oil, totaling the following favorable changes are as follows:
bullet improve the flow properties of blood and thus blood flow
bullet
reduce the risk for atherosclerosis, heart attack , stroke and blood clots
bullet
lowering blood fats (triglycerides) and LDL-cholesterol
bullet
lowering blood pressure
bullet
damping Herrzrhythmusstörungen
bullet
May cause kidney problems and may be helpful to counteract the effects of some Immunsepressiva.

may Prevents cancer, particularly breast cancer.
bullet
Can psoriasis counter and are used to treat it.
result of competition between the "evil" arachidonic acid (in the meat from factory farms, in sunflower oil) and the "good" eicosapentaenoic acid (EPA) (in fish oil) is displaced with abundant supply of EPO, the arachidonic acid by the enzyme system so that the pro-inflammatory leukotrienes are formed reduces the so-called 4-series from arachidonic acid, while the "good" leukotrienes may be formed of the so-called 5-Series from the EPA increased. This is beneficial for allergies, asthma, atopic dermatitis, chronic inflammatory diseases (Crohn's disease, ulcerative colitis, Hashimoto's thyroiditis, rheumatoid arthritis, psoriasis, multiple sclerosis), migraine, premenstrual syndrome, menstrual complaints and menopausal complaints.
omega-3 fatty acids that help curb antagonists of arachidonic acid and inflammation.
dosage:
bullet
people suffering from arthritis or suffer psoriasis can take up to 4 g / day.
bullet
As a dietary supplement without medical advice, up to 1 g / day is recommended.
The uncontrolled use of fish oil can lead to side effects
bullet
... Omega-3 fatty acids change the flow of blood. Sun Eskimos have a prolonged bleeding time, which means it takes longer for the blood clots. This is the one to protect against cardiovascular disease, on the other violations are observed in increased bleeding, which can also be dangerous.
bullet
... The fatty acids contained in fish oil capsules are very sensitive to oxidation. The gelatin capsules can be by air oxygen, which oxidises the fatty acids one by one. These oxidized fatty acids have no positive effect, but must be rendered harmless by the body. Recommended to take in combination with antioxidants is (vitamin C, vitamin E and selenium).
bullet
... When recording of large amounts may cause nausea and vomiting.
bullet
... For Diabeteker fish oils can be harmful, they cause a blood sugar increase and decrease in insulin secretion.
One advantage of high quality fish oil capsules as a dietary supplement is the continuous, daily intake. Note, however, that were not used to produce cheap fish waste. Optimal products are made from deep-sea fish, as these animals are less contaminated with pollutants, combined with antioxidants that can prevent the oxidation of polyunsaturated fatty acids.
Natural food sources are especially herring, salmon, tuna and crab.
