=======================================================
There are many people the world over, who have either fish oil or cod liver oil as a part of their daily food consumption. However, now, with the fish oil vs cod liver oil debate, people are in a fix and want to know, which of the two is better for health and should be taken. Both these oils contain beneficial elements for the human body. It will depend on the dietary habit and lifestyle of the person, which oil should be taken by that person.
Fish Oil Versus Cod Liver Oil
We will go deep into the fish oil vs cod liver oil debate, but before that, we must see what is it that is common to both these oils. Both fish oil and cod liver oil are rich in heart healthy omega 3 essential fatty acids. These are polyunsaturated fatty acids and they are necessary to counter the level of omega 6 fats in the body. According to a study, most Americans have dangerously high levels of omega 6. Increasing the consumption of omega 3 is helpful in reducing the harmful fats from the body.

Cod Liver Oil
Cod liver oil is rich in vitamin A and vitamin D along with the omega 3 essential fatty acids. Due to certain cod liver oil benefits, it is recommended to take this oil in winters, when the person is does not get sufficient amount of vitamin D from the sun. It is therefore also known as the ‘sunshine vitamin’. If cod liver oil is taken in summers by people living in the Northern United States and Canada, there are chances of toxicity from excess accumulation of vitamin D from the sun, along with the dietary sources, vitamin supplements and cod liver oil. At the same time, if the person lives in the southern states of United States, it is recommended, that they avoid using cod liver oil all year around.
Fish Oil
Fish oil can be beneficial as a dietary supplement for everyone above the age of four and who have sufficient exposure to sunlight. Fish oil is rich in omega 3 essential fatty acids, however unlike cod liver oil it does not contain vitamin D. Vitamin D is present in the liver of the fish and fish oil that is made from the whole body of the fish, contains insignificant quantities of vitamin D in it. Fish oil is recommended for people who get lot of sun exposure and/or who eat a lot of fish, which are naturally rich in vitamin D, such as salmon, mackerel and sardines. At the same time, if the person lives in an area, where the weather is warm all around the year and the skin is exposed to the sun, he should consume fish oil as against cod liver oil. Women, who are pregnant or are nursing during the summer months, should consume fish oil and not cod liver oil.
From the fish oil vs cod liver oil debate, the conclusion that was drawn is that cod liver oil should be taken by those, who stay far away from the equator and are not adequately exposed to sunlight. There are people, who are allergic to sunlight, and hence do not step out in the sun. They may therefore be prone to a vitamin D deficiency. Such people are recommended to take cod liver oil. If you are going to start of with either cod liver oil or fish oil, you may want to consult your health care professional. If blood tests are recommended, it is good to get the blood tests done. In case the blood tests show the level of vitamin D to be greater than 50 ng/ml, you will be advised against taking cod liver oil.
