Difference 3: Different main functions

The liver of cod is large and high in oil. In addition to DHA and EPA, which are all found in ordinary fish oil, it is also rich in vitamins A, D, E and other vitamins that are essential to the human body. It is a high-quality raw material for extracting cod liver oil. The ratio of these nutrients in cod liver oil is exactly the optimal ratio for the daily requirement of the human body.

In addition, cod meat is rich in magnesium, which is beneficial for preventing cardiovascular diseases such as hypertension and myocardial infarction, and has a good protective effect on the cardiovascular system. Therefore, cod is known as "gold in the sea" and "nutritionist on the table" in Europe.

Oily fish is mainly used to refine industrial lubricants - it contains a natural wax ester called scombrotoxin. Since the human body cannot decompose and absorb it, eating it can easily cause stomach cramps, and oil accumulates in the rectum, leading to oily diarrhea.
