Why is it useful?
All beneficial properties and effects on the body are determined by the combination of substances contained in cod liver.
The composition and benefits make cod liver a superfood. It is important to know how to use it correctly , observing daily norms.
For adult men and women
For adults, vitamin D, which is 250 times more abundant in cod liver than in beef liver, is necessary for the renewal of cartilage and bone tissue cells.
And bone healing occurs faster thanks to zinc, calcium, magnesium - isn’t this the benefit that canned cod liver can bring to adult men and women?
Heparin thins the blood , helping to prevent blood clots, ω-3 PUFAs help blood vessels avoid cholesterol plaques, and the heart contracts more rhythmically, as they have an antiarrhythmic effect.
When the required volume of ω-3 PUFAs enters the bloodstream, joint inflammation is effectively relieved, and patients with arthrosis and rheumatism begin to feel better.
Psycho-emotional changes are also noticeable - fatty acids prevent stress because they stimulate the production of the happiness hormone serotonin.
For pregnant and lactating women
Will cod liver be beneficial or harmful in the diet during pregnancy and lactation?
For a long time, medicine has recommended that pregnant women introduce cod liver into their diet, considering it a means of preventing anemia and a source of vitamins entering the body.
But modern research has led to new recommendations, according to which, due to the too high content of vitamin A, it is recommended to avoid cod liver during pregnancy.
If too much retinol enters the expectant mother's body , the developing fetus is harmed, causing developmental defects and possibly liver damage.
This product is especially harmful in the first trimester , since the fetus may develop damage to the nervous system, developing genital organs and limbs.
The product should be introduced into the diet after the start of breastfeeding - vitamins and microelements contribute to the formation of lactation.
But this must be done gradually and carefully, without eating canned cod liver in its pure form, but adding a side dish of rice and bread to it.
For children
Is canned cod liver good for children? These canned foods are not recommended for children under 3 years of age .
But for teenagers, especially during periods when accelerated growth is observed, a high vitamin D content will be useful - the risk of developing skeletal deformities, stoop, and scoliosis is reduced.
contained in cod liver stimulates brain activity , which is especially important for high school students.
Students who regularly receive fish oil in their diet show improved results, and children who are lagging behind in development catch up to the level of their peers within a few months.
For the elderly
Unsaturated acids preserve the ability of memory to retain information, stimulate mental activity, and, by and large, preserve memory and intelligence, which is the prevention of Alzheimer's disease.
You shouldn't wait until you're old to start eating cod liver. You should start protecting yourself from senile dementia in your young years by including this product in your diet.
The product, of course, is too fatty , and excess fat is contraindicated for any person: the older he is, the less fatty the food should be.
But by reducing the standards, older people can safely eat up to 30 g of canned cod liver per day.
High fat content is compensated by an abundance of nutrients that the body especially needs from a certain age.
Beneficial features
Fish oil is easily absorbed by the body and is easily oxidized. The body saves nitrogenous material used to build tissue.
It penetrates through the pores of cell membranes more easily than other fats, which gives a significant advantage even over vegetable oils.
The value of all fish oils is the content of Omega-3 (ω-3) PUFAs, which are necessary for the formation of connective tissues, mitochondrial filaments, cell membranes, and the myelin sheath of nerves.
This also includes actively preventing the development of vascular and heart diseases , which is associated with the ability of cholesterol in the presence of PUFAs to form esters that are easily transported through blood vessels.
ω-3 PUFAs reduce the risk of diabetes and insulin resistance.
Phosphorus, bromine, iodine, salts, and bile pigments are present in small amounts, which is why they cannot exhibit their inherent therapeutic qualities.
Thanks to other components , fish oil lowers cholesterol, prevents the development of arrhythmia , improves memory, preserves the brain, and reduces joint inflammation.
Cod liver can be consumed if you have diabetes, but with caution, all because of the same fat content.
The food is heavy and difficult to digest, but this deficiency is compensated by the varied vitamin and mineral composition that diabetics need.

Potential dangers and contraindications
Each product, in addition to positive qualities, also has negative ones. They appear when people stop remembering moderation.
Fatty foods should not be consumed uncontrollably in unlimited quantities. High calorie content is a potential danger of any highly nutritious product.
This may seem like an advantage to some, but for most it is an undesirable side property attached to all the undeniable beneficial properties of the product.
It cannot be said that cod liver is indiscriminately merciful to everyone; it also has plenty of contraindications:
- seafood allergy;
- fish oil intolerance;
- sand and stones in the kidneys or gall bladder;
- hypotension.
But for most people from the listed groups, cod liver is not a prohibited food.
By contacting your doctor, you just need to find out how often you can eat this product, because uncontrolled use leads to an excess of retinol in the body.
Excess vitamin A has a bad effect on your general condition , causing pain in the bones, drowsiness, nausea, peeling skin, skin rashes, and increased cholesterol levels in the blood.
It is problematic for a person to accumulate excess vitamin D, of which there is a lot of cod liver , because the body knows how to store it for future use, but if this happens, then one cannot avoid headaches, weakness, loss of appetite, nausea or even vomiting.
It is unlikely that it will come to an excess of other vitamins, since the liver contains the most vitamins A and D. They will be the first to signal an imbalance.
