MAJOR COMPONENTS OF COD LIVER OIL
Cod liver oil is a supplement for nutrition that is gotten from cod fish’s liver. Just like most other types of oil gotten from fish, cod liver oil has very high quantity of omega-3 fatty acids, vitamin A and vitamin D. The cod liver oil is light yellow in color and is often taken as a preventive technique against deficiency diseases especially for babies.
The process of manufacturing cod liver oil was initially by using sea water and fresh cod livers to fill up wooden barrels for about a year giving the mixture time to ferment. After this period, the oil is then removed. In recent times however, the process of manufacturing cod liver oil entails cooking the tissues of the cod body of fatty fish when the fish meat is manufactured.
The components of the cod liver oil include:
Omega-3 Fatty Acids
Omega-3 fatty acid that has a relationship with human physiology is divided into 3 types. These include the docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA) and α-linoleic acid (ALA). Other sources of the omega-3 fatty acids apart from the cod liver oil include walnut, Ischium oil, flaxseed oil, clary sage seed oil, hemp oil, sacha inchi oil, edible seed, egg oil, krill oil, fish oil and squid oil.
Omega-3 fatty acids have a lot of prospects for clinical uses and treating a wide range of illnesses. The omega-3 fatty acid is useful as it helps to improve metabolism. The acid is said to contain anti-inflammatory activities. Inflammation in the blood is said to reduce if omega-3 fatty acids gotten from marine sources are consumed. Furthermore, omega-3 fatty acids supplements is believed to have positive effect on individuals especially children suffering from developmental disorders. Omega-3 fatty acid is also believed to be useful in treating depression. Another aspect omega-3 fatty acids is considered useful is in the prevention of dementia. Omega-3 fatty acid is also useful in the therapy and prevention of atopic diseases. The acid could also protect against sudden death especially from cardiac arrest.
Since the 1930s, omega-3 fatty acid health benefits were noticed and has continued to increase dramatically especially during the 1980s. Other types of omega-3 fatty acid include Hexadecatrienoic acid (HTA), tetracosapentaenoic acid, stearidonic acid (SDA), Tetracosahexaenoic acid and Eicosatrienoic acid (ETE).
Eicosapentaenoic acid (EPA)
The Eicosapentaenoic acid can be gotten from fish oil such as mackerel, menhaden, sardine, salmon and cod liver as well as from breast milk of humans and seaweed phytoplankton. The Eicosapentaenoic acid that are produced from fish are gotten from the algae that fish eat. The human body also has the capability to get Eicosapentaenoic acid by converting α0linolenic acid. Some factors such as certain allergies and diabetes has the ability to prohibit the capacity of the human body to metabolize Eicosapentaenoic acid from α-linoleic acid.
The clinical importance of Eicosapentaenoic acid includes its function of being able to reduce the rate of inflammation. It has also been posited that Eicosapentaenoic acid particularly could be useful in treating schizophrenia and other mental conditions. It also has the ability to increase the way patients respond to chemotherapy.
Docosahexaenoic acid (DHA)
Docosahexaenoic acid is a structural component of many parts of the body including the retina, sperm, testicles, skin, cerebral cortex and human brain. Docosahexaenoic acid can also be synthesized from α-linoleic acid or gotten directly from the milk from a nursing mother as well as from fish oil. Fish oils from cold water oceans contain a high content of Docosahexaenoic acid. Docosahexaenoic acid could also be produced from microalgae. Studies have shown that Docosahexaenoic acid helps in improving memory and has the ability to reduce the effects of Alzheimer’s disease neuropathology when it was tested on mice.
When also tasted on mice, Docosahexaenoic was also discovered to reduce the human colon carcinoma cells growth more than when compared to other omega-3 polyunsaturated fatty acid. Docosahexaenoic acid was also found to improve the effect of prostate cancer cells in vitro chemotherapy.
Foods containing omega-3 fatty acids have also been recommended women who are nursing or who are looking forward to get pregnant.
Vitamins are one of the classes of food and they are very good for the body. Vitamin A has different types which are often depicted by alphabets such as Vitamin A, Vitamin B and Vitamin D amongst others. Vitamin A is a very important vitamin and is necessary for growth and development as well as for good vision and immune system. Other sources of Vitamin A apart from cod liver oil includes in vegetable and fruits.
Vitamin D is gotten from direct exposure to the sun, preferably the early morning sun before 12noon and the late evening sun after 4pm. The major use of Vitamin D is to prevent rickets and osteomalacia. It can also help to improve bone health of an individual.
