Nowadays, there are a lot of fish-oil products emerging in the market, which make consumers feel confused, regarding it as the same with cod liver oil. Then, what's the differences between cod liver oil and ?

In fact, no matter from the source of raw materials or the health effects on human health, there are considerable differences between cod liver oil and fish oil. Cod liver oil mainly comes from the fish liver, and its main components are vitamin A and vitamin D. Lack of vitamin A will cause night blindness and dryness of eyes. As a result, people who suffer from these diseases can eat more cod liver oil in their daily diets, so as to supplement enough vitamin A to the body.

As for the lack of vitamin D, it will lead to osteomalacia. Generally speaking, as long as the body receives enough sunlight, it can synthesize vitamin D by itself. However, as the synthetic ability of the elderly people is relatively very weak, so in order to maintain the health and strength of bones, they must pay attention to taking in more vitamin D. In such a case, they can consider using cod liver oil.

Fish oil is often confused with cod liver oil. In fact, fish oil is the extract from the fat of deep-sea fishes. Its main components are polyunsaturated fatty acids such as EPA and DHA. This kind of fatty acids can reduce the LDL cholesterol in the blood, slow the formation of blood coagulation and blood clot, and reduce the viscosity of blood fat. Fish oil can be used as a scavenger in the blood vessels, which can reduce the risk of vascular occlusion. What's more, fish oil can also prevent arteriosclerosis, obesity, hypertension and heart disease, increase the learning ability and memory of the brain cells, and prevent stroke and dementia.

We should pay attention not to confuse cod liver oil with fish oil when using them. When you take in fish oil as cod liver oil, if the dose is very small, it will not cause great influence. However, if you eat cod liver oil as fish oil, it may cause serious results. Because vitamin A and vitamin D are fat-soluble vitamins, so long-term intake of cod liver in large quantities can cause these vitamins excessively accumulate in the body, which will lead to poisoning, and increase the brain pressure.

After learning the differences between cod liver oil and fish oil, we should be more careful when choosing these two kinds of food in our later life, so as not to cause irretrievable results because of the misuse of them.
