Cod - most valuable commercial fish sturgeon familiesknown for its dietary properties.
Her white meat contains many useful substances, while being quite low-calorie (70 calories per 100 g).
but most valuable to a person presents liver cod, which they canned.
The method of its preparation is very important here; the most useful method is rightfully considered to be the method of preparation from fresh fish. But today, quite often, frozen fish has been used, which, unfortunately, significantly reduces the amount of nutrients in it.
It is not possible to fully control the method of preparation of this product, this can be found out only from additional information about the manufacturer: during the harvesting of fish, it should be located on water and immediately after the catch to begin the processing process. Therefore, when purchasing a product, it is recommended that more attention be paid to well-known, well-established brands and manufacturers.
To prepare the product correctly, it should be prepared in its own fat without vegetable oil with the addition of black pepper, sugar, salt and bay leaf.
Note. When buying, pay attention to the presence of vegetable oil. If it is present, this may mean that the fish was most likely frozen before cooking, which means it lost its beneficial properties due to lack of fat.

Vitamin Complex
Cod liver is very useful for human health, because it contains many useful vitamins, among which there are groups A, C, D, E, PP, B1, B2, B6, B9. Most of all, the product contains Vitamin A, a well-known antioxidant that has a beneficial effect on the quality of vision, preservation of beauty and youth.
Vitamin B is very important for the nervous system, it perfectly protects a person from manifestations of stress, irritability and excessive fatigue. They also contribute to the natural process of metabolism of fats in the body and the transformation of calories into energy, and not into body fat.
Minerals
The product also has a decent mineral complex. The product contains a huge amount of the following minerals, macro- and microelements:
phosphorus;
magnesium
calcium;
potassium;
zinc;
chromium;
Fluorine;
and many other equally important elements.
Each of them has an indispensable positive effect on the cardiovascular system, magnesium and potassium, for example, help the heart muscle, phosphorus significantly improves brain function, and calcium perfectly strengthens bones, nails, hair, teeth and connective tissues. In general, all of the above elements are important for the natural and healthy functioning of the human body.
I would also like to talk about such an important component as omega-3 fatty acid. As was proved by scientists, the human body is greatly deprived of this valuable substance, and it is very lacking in modern life. The thing is that in our time, various diets, involving the complete rejection of animal fats, and excessive consumption of fast food products (the so-called Fast Food), in which there is a huge number of vegetable empty fats, have gained great popularity.
For the above reasons, a large deficiency of this acid, and this is fraught with serious consequences, since it is responsible for the prevention of diseases such as:
atherosclerosis;
heart attack;
lupus;
bronchial asthma;
tumors of varying degrees.
Cod liver is very good for health, and it is rightfully one of the most valuable products in the world, so its presence in the diet of any person is not in doubt.
In most countries, particularly in Russia, people have serious iodine deficiency. To use iodine under the guise of an additive is not appropriate and justified, this process should be under the supervision of a doctor. But the presence in the diet of the liver of cod, which contains a large amount of iodine, is a completely different matter, since in this form iodine is absorbed much better than in chemical form.
The benefits of cod liver for people of different ages

Also, it can be taken by pregnant and lactating mothers, you only need to observe the measure. Cod liver is very useful for the fetus, because it contains a lot of nutrients, and lactating mothers will be able to pass vitamin D to the baby through breast milk, which is an excellent preventive measure against rickets. However, do not forget that an excess of vitamin A can adversely affect the development of the fetus, therefore, overdoing is also not recommended.
Cod liver: harm
As mentioned above, the product can not be consumed in an unlimited number, as this is fraught with an excess of vitamin A in the body, which can lead to allergic rashes.
Today, cod liver can rarely be found fresh, except for canned food. Products stored in an open metal can are harmful. In this case, dangerous bacteria can appear in it that can poison the human body.
Attention! The period of storage of the product in an open vessel should not exceed 24 hours, and it must be not metal, but glass containers.
Heavy metal toxins can be in canned food, which is quite common for this type of packaging. For example, furans and dioxins, the strongest carcinogens that enter the human body and are difficult to remove, can be collected in the liver of Baltic cod. These substances are dangerous in that they can provoke the development of cancer, adversely affect the functioning of the immune system and reproductive function, as well as become a consequence of the appearance of external and internal birth defects in the fetus. Therefore, cod that lives in the Atlantic Ocean is safer in this case; no such carcinogens have been detected in its liver.
You also need to remember that cod liver must be consumed with bite with other products, such as bread or salad. As mentioned above, the product is only useful in moderation.
