Fish oil comes from fatty fish tissues, known equally as the oily fish such as trout, mackerel, tuna, herring, sardines, and salmon.
Fish oil captured the attention of nutritionists and health professional dues to the two main ingredients – docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), both part of the Omega-3 fatty acids.
According to American researchers, the lack of essential nutrients in the body, which are found in fish oil, causes the decline in brain mass and brain functions.
People who adopt a diet low in Omega-3s, have a smaller brain mass, and the difference compared to people who consume fish oily on a daily basis is equivalent to two years of aging.
The low concentration of omega-3 fatty acids has been associated with the poor outcomes on tests of visual memory, with the emergence of some issues related to solving multiple problems and difficulties encountered in processes associated with abstract thinking.
Fish oil is, in fact, like a magical potion that can strengthen heart health, fertility and support weight loss. It also helps you have a clean and healthy looking complexion. Moreover, this miracle oil reduces the effects of depression, ulcers, diabetes and many other affections. One of its major benefits is the fact that it may prevent Alzheimer’s disease.
According to a recent study published in the journal Alzheimer’s and Dementia, which included 819 participants, taking fish oil supplements daily may result in cognitive decline and brain atrophy.
There are several types of omega-3 fatty acids. Two of them are extremely important – EPA and DHA, and are found primarily in certain fish. Some plants, such as flax, contain ALA, an omega-3 fatty acid that turns partially into DHA and EPA once inside the body. The oil from algae often provides only DHA.
Research has shown that the DHA polyunsaturated fatty acids, contained in most fatty fish, indeed nourish the brain. In its capacity as a major constituent of the lipids in the brain and nerves, DHA is vital to normal functioning of the tissues. DHA is part of the phospholipids of the retina and synapses and constitutes 60% of the lipids in the brain and nerve tissue.
DHA plays a central role in brain development and central nervous system in young children. Studies have shown that children who received an additional intake of DHA, successfully passed intelligence tests, performing much better than those who had a DHA deficiency in their diets.
People who include fish oil in their diets have a lower incidence of obesity, heart disease, and even age-related memory disorders. The prevalence of this good fat in the diet is regarded as one of the possible reasons for which the overall health is improved.
It seems that the moderate consumption of fish, meaning once or twice a week, lowers the risk of having a stroke by 27%. However, if a serving size of fish exceeds 46 grams of fish per day, the effect is reversed, thus increasing the stroke risk. If you’re taking aspirin for prevention, keep in mind that eating fish will not lower the stroke risk.
As a source of good fat, the fish oil benefits include reduced inflammation, lower risk of cancer, mental health improvement, and healthier skin.
