Diets and healthy eating 27.10.2017
Dear readers, our today's conversation will be about such a well-known offal as cod liver. This product is not the cheapest, since Soviet times it has been considered a delicacy. Cod liver is popular due to its special delicate taste and the fact that it is easily combined with different dishes. It can be eaten alone, in salads or sandwiches, with spaghetti or in puree soup, etc.
I have my own associations with cod liver. Let me tell you a funny story. My sister and I came to visit our parents together with the children. They were still small. They took with them a jar of cod liver. Then buying it was a whole event! We sat at the table, and then went for a walk. And my nieces took an open jar with them (we didn’t see it ...?). And they put it in the pocket of a brand new, beautiful jacket.
How they managed to eat it, we don't know. But then the jacket could not be washed off. But the children were delighted with such a delicacy. How many years have passed, and still we remember everything with a smile. And most importantly, everyone still loves her. And after such an introduction, we continue the conversation more seriously about the benefits and possible harms of cod liver for our health, its composition and how to choose it correctly in stores.
Cod is a fish from the cod family of the same name, and it accumulates valuable fish oil and other important components in its liver. We use canned cod liver, because this is the only way this product can get to our table from the northern seas. The fact is that the liver of this fish quickly deteriorates, and therefore urgent preservation is simply necessary. We will talk more about canned food with our delicacy product later.
The composition of cod liver can impress just as much as its taste. The product contains:
- vitamins A, B (including folic acid), C, D, E, K;

- polyunsaturated fatty acids, including Omega-3;

Cod liver contains 67% fish oil and is an excellent source of Omega-3 polyunsaturated fatty acid. The benefits of cod liver are a combination of Omega-3 and a rich vitamin and mineral complex. This product is able to take care of our health at the highest level. But at the same time, the calorie content of the sea delicacy should be taken into account.
How much can you eat cod liver per day
The calorie content of cod liver is high - 613 kcal per 100 g. The product is preserved in fish oil or oil, so it contains a lot of cholesterol. But the danger of this cholesterol is neutralized by the very composition of fish oil. This is "good" cholesterol, which does not settle on the walls of blood vessels.
Due to the high calorie content, cod liver should be consumed with caution if overweight.
The daily norm for adults is 30-40 g of liver. In reasonable quantities, tasty and nutritious seafood will make the diet healthier. The beneficial properties of cod liver are enough to include it in the diet for a number of diseases.

Harm and contraindications
The benefits and harms of cod liver depend not only on the amount in which it is consumed. This delicacy has its own contraindications:

- hypotension, as cod liver lowers blood pressure;

Pregnant women, as already mentioned, need to observe the measure in the use of cod liver in a special manner. An excess of retinol can disrupt the normal formation of the fetus, lead to malformations, especially in the first trimester.
canned cod liver
What's the use canned liver cod, if it is not a fresh product? We are unlikely to find this delicacy in its raw form - cod is caught in the sea, the liver is removed and immediately preserved (no more than 6 hours should elapse between catching fish and extracting the liver). There are floating factories, because the product deteriorates quickly and it makes no sense to transport it if it takes a long time. It is important that during canning they do not resort to heat treatment, fish oil or oil and salt serve as a preservative. This allows the liver to retain its rich composition.
There are not many floating plants, and cod liver is often canned at enterprises located in ports, on the coast. The main thing is that the fish should not be frozen for a long time - it will not be the same product either in terms of nutritional or beneficial properties.
If the raw material for canned food is frozen cod, it is better to refuse to buy.
How to choose canned food
The best canned cod livers are those cooked in a swim. Therefore, it is worth looking for a corresponding notice on banks. This product is top notch. Canned food made from fresh cod at factories located on the sea coast will be of the first grade. As a rule, these are enterprises of the Arkhangelsk and Murmansk regions.
Pay attention to composition. On canned cod liver, the composition should contain a minimum of ingredients: the liver itself, fat (oil), salt. Spices in the form of black pepper and bay leaf are also allowed.
You should not choose suspicious tin cans - with traces of rust, with dents and uneven shape, especially with swelling. Best of all classic smooth and durable can stamped from the inside to the outside with the production date and expiry date. Such a product will comply with GOST.
Cod- the most valuable commercial fish sturgeon family, known for its dietary properties.
Its white meat contains many useful substances, while being quite low in calories (70 calories per 100 g).
but the greatest value for a person presents liver cod, from which canned food is produced.
The method of its preparation is very important here, the method of preparation from fresh fish is rightfully considered the most useful. But today, frozen fish has been used quite often, 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 only be found out from additional information about the manufacturer: during the preparation of fish, it must be located on the water and immediately after the catch, the processing process should begin. Therefore, when purchasing a product, it is recommended to pay more attention to well-known, well-established brands and manufacturers.
To prepare the product correctly, it must 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 in the composition. If it is present, it may mean that the fish was most likely frozen before cooking, which means that it has lost its beneficial properties due to the lack of fat.
Atlantic cod liver is a very popular product that is used for cooking various salads pates and other dishes. For its manufacture, the fish is bred and grown in special nurseries. In addition to cooking, this product is widely used in treatment, for example, for the production of the most valuable and useful fish oil.
What other useful properties are contained in the product?
Cod liver: benefits
Vitamin complex
Cod liver is very beneficial for human health, as it contains many beneficial vitamins, among which there are groups A, C, D, E, PP, B1, B2, B6, B9. Most of all, the product contains vitamin A - the most famous antioxidant that has a beneficial effect on the quality of vision, the 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 body's natural process of fat metabolism and the transformation of calories into energy, and not into body fat.
Minerals
The product also contains a decent mineral complex. The product contains a huge amount of the following minerals, macro- and microelements:
-
and many other equally important elements.
Each of them has an irreplaceable 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.
Separately, I would like to talk about such an important component as omega-3 fatty acid. As it has been proven by scientists, the human body is severely deprived of this most valuable substance, and it is very lacking in modern life. The thing is that in our time, various diets have gained great popularity, implying a complete rejection of animal fats, and excessive consumption of products. fast food(the so-called Fast Food), which contains a huge amount of vegetable empty fats.
For the reasons described above, a large deficiency of this acid appears in the body, and this is fraught with serious consequences, since it is responsible for the prevention of diseases such as:
lupus;
bronchial asthma;
tumors of varying degrees.
atherosclerosis;
Cod liver is very healthy, and it is rightfully one of the most valuable foods in the world, so its presence in the diet of any person is not in doubt.
In most countries, in particular in Russia, people have a serious iodine deficiency. It is not appropriate and justified to use iodine under the guise of a supplement; this process should be under the supervision of a physician. But the presence of cod liver in the diet, 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 all ages
The product will be of great benefit to adolescents, since it has a positive effect on the formation of the bone skeleton and the central nervous system. It will also be very useful for the elderly, as with its help you can maintain health longer and prolong life. There is official information that cod liver - excellent preventive measure against Alzheimer's disease.
It can also be taken by pregnant and lactating mothers, you just need to follow the measure. Cod liver is very useful for the fetus, because it contains a lot of useful substances, and nursing mothers can transfer vitamin D to the baby through breast milk, which is an excellent preventive measure against rickets. However, we must not forget that an excess of vitamin A can adversely affect the development of the fetus, so overdoing it is also not recommended.
Cod liver: harm
As mentioned above, the product should not be consumed in unlimited quantities, as this is fraught with an excess of vitamin A in the body, which can lead to allergic rashes.
Today, cod liver is rarely found fresh, except for canned food. Harmful is the product stored in an open metal can. 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 container should not exceed 24 hours, and it must be not a metal, but a glass container.
Canned food may contain heavy metal toxins, which is quite common for this type of container. For example, in the liver of the Baltic cod, furans and dioxins tend to accumulate - the strongest carcinogens that enter the human body and are difficult to excrete. These substances are dangerous because they can provoke the development of oncological diseases, negatively affect the functioning of the immune system and reproductive function, and also become a consequence of the appearance of external and internal birth defects in the fetus. Therefore, cod living 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 other foods, for example, bread or salad. As mentioned above, the product is useful only in moderation.

As mentioned above, women during pregnancy can use this product, but its excess can adversely affect the development of the fetus. We are talking about vitamin A group, its oversaturation in the body can cause various defects in the fetus, as well as damage the liver. Also, too much retinol can negatively affect the condition of the mother herself, causing her to experience drowsiness, nausea, and bone pain. It is especially important to monitor the consumption of the product during the first trimester.

And some secrets...
The story of one of our readers Alina R.:
My weight especially bothered me. I gained a lot, after pregnancy I weighed like 3 sumo wrestlers together, namely 92 kg with a height of 165. I thought my stomach would come down after childbirth, but no, on the contrary, I began to gain weight. How to deal with hormonal changes and obesity? But nothing disfigures or rejuvenates a person as much as his figure. In my 20s, I first learned that fat girls are called "WOMAN", and that "they don't sew such sizes." Then at the age of 29, a divorce from her husband and depression ...
But what can you do to lose weight? Laser liposuction surgery? Learned - not less than 5 thousand dollars. Hardware procedures - LPG massage, cavitation, RF lifting, myostimulation? A little more affordable - the course costs from 80 thousand rubles with a consultant nutritionist. You can of course try to run on a treadmill, to the point of insanity.
And when to find the time for all this? Yes, it's still very expensive. Especially now. So for myself I chose a different way ...
