Arctic cod liver oil: superstar for healthy ageing and immunity

<div class="Maincontent">
<p><strong>We all need good nutrition for optimum wellbeing but this may be of even greater importance in our golden years. Of the many nutrients that benefit healthy ageing, omega-3s are superstars since they are essential to the proper functioning of every cell in our bodies.</strong></p>
<p>The main beneficial omega-3s, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are naturally highly concentrated in Arctic cod liver oil. The difference between Arctic cod liver oil and other fish oils is that Arctic cod liver oil generally contains 50% more DHA than EPA, whereas other fish oils are naturally higher in EPA than DHA.</p>
<p>This ratio makes<span> </span><a rel="noopener noreferrer" href="http://www.therahealth.com.au/" target="_blank">Arctic cod liver oil</a><span> </span>stand out as a superfood for supporting systems that have an abundance of DHA such as the brain and eyes. In addition to this, Arctic cod liver oil contains a rare supply of naturally occurring vitamins A and D, providing further support for a range of body systems such as skin cell and immune support.</p>
<p>Here are 6 ways that the nutrients found in Arctic Cod Liver Oil have been shown to support ageing & immunity:</p>
<p><strong>1. Heart health</strong></p>
<p>Increasing levels of evidence have shown the beneficial impacts of dietary Omega 3’s against heart disease, and gaining sufficient omega-3 might be easiest done in the form of a cod liver oil supplement<span> </span><sup>(1)</sup>. Studies have indicated that dietary omega-3s appear to decrease the cardiovascular risk factors that lead to heart disease<span> </span><sup>(2,3)</sup>. This has been particularly obvious when cod liver oil supplementation has occurred in the Western diet. One particular study found that supplementing a typical Western diet with cod liver oil had positive effects on the heart health of study participants<span> </span><sup>(1)</sup>.</p>
<p>This was likely due to the high concentration of omega-3’s contained in cod liver oil. As cardiovascular disease is a prominent health issue in Australia, Arctic cod liver oil may be an important addition to one’s diet in support of improving heart health<span> </span><sup>(4)</sup>.</p>
<p><strong>2. Brain health</strong></p>
<p>The brain tissue of humans is predominantly composed of lipids, which are made up of different fatty acids. DHA is the most abundant fatty acid in the brain. The levels of DHA in the brain increase during development and decrease with ageing. Further to this, DHA levels in the brain can be altered by dietary intake of omega-3s<span> </span><sup>(5)</sup>.</p>
<p>A number of studies have suggested that low levels of DHA in the brain are linked to an increased risk of cognitive decline and dementia in older adults<span> </span><sup>(6)</sup>. Therefore, because of the rich profile of DHA in cod liver oil, supplementation of this particular fish oil may be specifically beneficial for the ageing population in support of brain health.</p>
<p><strong>3. Bone strength</strong></p>
<p>One of the main draw factors of cod liver oil is its naturally occurring vitamin D. While the most abundant method for increasing one’s vitamin D status is usually through sunlight exposure, sufficient and safe amounts of healthy sun exposure are increasingly difficult to achieve for many in the modern population.</p>
<p>Therefore, cod liver oil supplementation may be a valuable alternative for supporting one’s required daily intake of vitamin D for optimal bone health. Osteoporosis is a bone disease characterised by decreased bone mass that occurs primarily in postmenopausal women<span> </span><sup>(7)</sup>. This disease places them at greater risk of fractures in their later life. Therefore, cod liver oil may be beneficial for supporting bone development and maintenance throughout life, and particularly in later life when the risk of bone fracture is increased.</p>
<p><strong>4. Vision</strong></p>
<p>Deteriorating eyesight is a common health problem in the ageing population. As with the brain, the eye is highly enriched with omega-3 fatty acids, with particularly high levels of DHA present in the retina of the eye<span> </span><sup>(8)</sup>. Therefore, DHA has an important functional role in the retina, primarily helping minimise the damage that is caused from the ongoing exposure to light throughout life<span> </span><sup>(12)</sup>.</p>
<p>Therefore, people over the age of 50 are recommended a regular intake of marine fish or a food supplement that has high concentrations of DHA, such as cod liver oil, to support their eye health<span> </span><sup>(12)</sup>. In addition to this, cod liver oil is appealing because it is a good source of naturally occurring vitamin A in its most ‘active’ form, which may support individuals who have problems with night vision.</p>
<p><strong>5. Skin care</strong></p>
<p>Human skin plays a pivotal role in the feeling of wellbeing and physical attractiveness in an individual<span> </span><sup>(14)</sup>. Our skin is continuously exposed to internal and external influences that may alter its condition. As a result, we may experience inflammation, immune dysfunction, skin disorders, and ultimately ageing.</p>
<p>The functioning and attractiveness of the skin are dependent on nutrition, as evidenced by the characteristic skin lesions that often occur from particular deficiencies in the diet.<sup><span> </span>(14)</sup><span> </span>Dietary supplementation with specific vitamins, minerals, or essential fatty acids will therefore support skin care in these situations<span> </span><sup>(15)</sup>. Many reports have suggested that the intake of omega-3s, (EPA and DHA), may provide considerable health benefits in relation to inflammatory diseases that have the potential to cause rashes, lesions or other disorders to the skin. One study found that a relatively low supplemented dose of EPA and DHA within a 4-week period was protective against UV radiation<span> </span><sup>(16)</sup>. Therefore, cod liver oil supplementation may be recommended to help and support skin care in later life.</p>
<p><strong>6. Immune system</strong></p>
<p>Many studies have found that the anti-inflammatory profile of cod liver oil supports the immune response of an individual. Further to this, the effect of omega-3 dietary supplementation has been shown to improve clinical variables of disease activity<span> </span><sup>(17)</sup>. One study found that cod liver oil supplementation for individuals with rheumatoid arthritis allowed these patients to decrease their NSAID (non-steroidal anti-inflammatory drugs) intake, thus improving gastrointestinal and cardiovascular health without any worsening of disease activity<span> </span><sup>(17)</sup>.</p>
<p>Another study produced results that suggested a protective effect of cod liver oil supplementation against type 1 diabetes<span> </span><sup>(18)</sup>. Numerous changes occur in the immune system with advancing age, probably contributing to a decreased immune response<span> </span><sup>(20)</sup>.</p>
<p>Looking at these amazing benefits for multiple body systems, you can see why Arctic cod liver oil is a superstar for immune support and healthy ageing.</p>
