The liver was distinguished by the content of minerals. She cannot boast of a high amount of macronutrients, such as phosphorus. But iron, copper, cobalt, molybdenum, manganese, selenium and other, including rare, trace elements abound in it. In many respects, the liver is ahead of many products, the price of which is often much higher.

The benefits of beef liver for humans

Effect on hematopoiesis

One of the first recommendations that people who are diagnosed with anemia hear, whether it is B12 deficient or not, is to eat beef liver. Of course, this is primarily due to the very high content of cyanocobalamin and iron in it. But many people forget that normal hematopoiesis requires protein, magnesium, copper and other trace elements, which are also abundant in this product. Due to its composition, the use of beef liver contributes to the replenishment of several dozen substances that are necessary for the functioning of the bone marrow.

From this point of view, the product is useful because their body has an increased need for protein, iron, vitamins and minerals.

Neurologists do not often advise their patients on diets, although the consumption of many foods has an impact on the health of the nervous system. The liver is one of them. The high content of B vitamins, especially B6, folic acid and various trace elements, promotes the regeneration of nerve cells, improves the conduction of impulses along nerve fibers and stimulates the brain.

Many scientists agree that people who eat beef liver at least once a week are less susceptible to age-related changes in the nervous system.

Effect on the heart and blood vessels

Of course, one cannot ignore the benefits of this offal for the cardiovascular system. Vitamins and minerals help strengthen the myocardium and increase the strength of blood vessels. Regular consumption of the liver once a week can help reduce the level of triglycerides in the blood, and it is these substances that lead to the development. The liver contains substances that thin the blood and prevent thrombosis.

Is beef liver harmful?

This question worries many, information about the dangers of this product can be found no less than about the beneficial properties. The greatest doubt is caused by the high cholesterol content in the liver, as well as the fact that the liver is, in fact, a filtering organ through which all harmful substances entering the blood pass and are neutralized.

Fats and cholesterol in the liver

Indeed, in the liver, as in almost any product of animal origin, there is both fat and cholesterol, but in this product their amount is not so large as to negate its beneficial properties. In fact, the fat content in it is several times lower than in other products.

100 g of liver contains up to 4 g of fat, which is several times less than in beef tenderloin or chicken egg. But there is really a lot of cholesterol in this product, but not more than in pork fillet. That is why the frequent use of beef liver for food is not recommended, but one serving (200-300 g) per week will only benefit. Even the most strict nutritionists believe that a relatively high cholesterol content is not a reason to completely abandon this most valuable product.

Does beef liver contain toxins?

Most likely, this issue is the most "sick" for the modern food industry around the world. As you know, the liver filters and neutralizes substances that enter the blood of an animal, but not all of them are required to accumulate in it, as many believe.

Modern animal husbandry, especially abroad, widely uses hormones and antibiotics, as well as mixed feed with various additives. In the United States, studies have been conducted for many years to identify the effect of these substances on the human body when they eat meat and offal of such animals. Some of them made it possible to link the rapidly developing obesity in the American nation with eating foods literally stuffed with various chemicals. However, there has been no official statement on this issue yet.

But one thing is for sure: the liver of young cattle that was on natural grazing (grass) contains less cholesterol, more vitamins, unsaturated fatty acids and other useful substances. In this regard, the number of so-called eco-farms has recently increased everywhere, where animals are grown in environmentally friendly conditions, without the use of drugs that accelerate the growth of an individual.

If you get on the table the liver of an old animal grown by unscrupulous farmers on compound feed, using medicines, then it will not only be tough and tasteless, but also not particularly useful. That is why you need to be especially careful when choosing this product, and if you are not sure of its quality, then it is better to refuse to buy.

Medical contraindications

This offal is contraindicated in Wilson-Konovalov's disease. In this case, this is not due to high cholesterol, but to the fact that a high concentration of copper was found in the liver, the metabolism of which in people suffering from this disease is impaired.

How to choose a good beef liver?

A quality product should have a uniform color and a smooth, even surface.

In fact, choosing a young liver that will be really useful is not so difficult, because its appearance speaks about the quality of the product. In some places in the markets you can find on sale not only beef, but also veal liver. The latter, after cooking, is softer and more tender, but contains more fat.

By the size of the internal organs, you can judge the age of the animal, so if you want to get a young liver, you should choose a product weighing no more than 2 kg.

When buying fresh chilled beef liver, you need to pay attention to its color. It should have a shade from light brown (usually calf's liver) to dark red, sometimes even with a cherry tint, its color should be uniform. Too much dark color liver speaks of the venerable age of the animal. The surface of the product should be smooth, shiny, even (not bumpy) and not sticky - the stale liver becomes matte and a sticky coating appears on it.

The liver section should also be homogeneous with a small number of pores; foreign inclusions should not be visible on it, only a section of blood vessels. If, when pressed on a piece, scarlet blood oozes from the cut, then the product is definitely fresh, but you will not see this on the second day after slaughter. Holes remain on the lying liver after pressing. If a light liquid oozes from the cut, then this is most likely water, in which unscrupulous sellers soak offal to extend their shelf life. Based on this, we can conclude that either blood should ooze from a section of the liver, or nothing.

If there is an opportunity and desire, then the product must be smelled, the smell should not be sharp or unpleasant, it is a little sweet, almost the same as that of fresh beef.
