Fish oil Omega 3, may prevent the onset of schizophrenia and other psychotic disorders long after being consumed.
- Schizophrenia is characterized by delusions and hallucinations, including hearing voices and seeing things that do not really exist.
Tuesday, a study was released, seven years after taking fish oil omega 3 supplements for 12 weeks, young people at high risk were less likely to have suffered the debilitating condition than a control group given a placebo. Only 10 percent of the fish oil omega-3 group developed psychosis compared to 40 percent in the placebo group.
According to report of Paul Amminger at the University of Melbourne in 2010, that a three-month course of daily fish oil omega 3 capsules appeared to stave off psychotic illnesses in teenagers and young adults aged 13 to 24 deemed at high risk of developing the disorders. Seven years on, his group has now revisited 71 of the original 81 participants and shown that the protective effects seem to persist.
Schizophrenia is one of the most common serious mental health conditions. One in 100 people in Britain experience symptoms, such as delusions, visual or auditory hallucinations, in their lifetimes, and many continue to lead normal lives. It is most often diagnosed between the ages of 15 and 35. It is called a psychotic illness, and those affected sometimes cannot distinguish between their thoughts and reality.
“Schizophrenia is a major cause of disability, but early treatment has been linked to better outcomes. Our study gives hope that there may be alternatives to antipsychotic medication,” Amminger said. Fish oil omega 3 “has no clinically relevant side effects, and thus is certainly a benign treatment option,” he added.
Fish oil is oil derived from the tissues of oily fish. Fish oils contain the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), precursors of certain eicosanoids that are known to reduce inflammation in the body, and have other health benefits.
The fish used as sources do not actually produce omega-3 fatty acids, but instead accumulate them by consuming either micro algae or prey fish that have accumulated omega-3 fatty acids, together with a high quantity of antioxidants such as iodide and selenium, from micro algae, where these antioxidants are able to protect the fragile polyunsaturated lipids from peroxidation.
Fatty predatory fish like sharks, swordfish, tilefish, and albacore tuna may be high in omega-3 fatty acids, but due to their position at the top of the food chain, these species may also accumulate toxic substances through biomagnification. For this reason, the United States Environmental Protection Agency recommends limiting consumption (especially for women of childbearing age) of certain (predatory) fish species (e.g. albacore tuna, shark, king mackerel,tilefish and swordfish) due to high levels of toxic contaminants such as mercury, dioxin, PCBs and chlordane. Fish oil is used as a component in aquaculture feed. More than 50 percent of the world’s fish oil used in aquaculture feed is fed to farmed salmon.
Marine and freshwater fish oil vary in contents of arachidonic acid, EPA and DHA. The various species range from lean-to fatty and their oil content in the tissues has been shown to vary from 0.7% to 15.5%. They also differ in their effects on organ lipids. Studies have revealed that there is no relation between total fish intake or estimated omega−3 fatty acid intake from all fish, and serum omega−3 fatty acid concentrations. Only fatty fish intake, particularly salmonid, and estimated EPA + DHA intake from fatty fish has been observed to be significantly associated with increase in serum EPA + DHA.IMAGE/Jonas N/Flickr
