Fish Oil vs Cod Liver Oil
Over the last few decades, because of over reliance on junk food and reduction in dietary intake full of nutrients, fish oil and cod liver oil have become very popular as nutritional supplements. These oils not only compensate for loss of nutrients, but also increase consumption of essential fatty acids that are considered to be extremely beneficial for our health. Today, the situation has become such that people are taking these oils without really knowing the differences between fish oil and cod liver oil. This article take a closer look at both these oils to enable readers to choose one that is healthier for them.
The fish oil has proven health benefits, especially Omega 3 fatty acids, including both EPA and DHA, that have excellent health benefits. Both DHA and EPA are considered to be essential for our body, but unfortunately human bodies do not have the ability to manufacture them. This is precisely the reason why we must obtain these essential fatty acids from outside. Both fish oil and cod liver oil have been proved to be excellent sources of these two essential fatty acids. Cod liver is made from the liver of white fish such as cod, and occasionally halibut, which implies that in principle, it is also a type of fish oil.

This imbalance between the ratio of Omega 3 and Omega 6 is of serious concern, which is sought to be rectified through higher intake of fish oil and cod liver oil.
Experts say that our forefathers or ancestors had a more healthy diet where the intake of Omega 6 and Omega 3 was nearly equal. But sadly, because of over reliance on junk food, our intake of Omega 3 has suffered badly; so much so that this ratio of intake is today 20:1 or even 50:1.
