Benefits of beef liver for humans

Effect on hematopoiesis

One of the first recommendations that people diagnosed with anemia hear, whether it is B12 deficiency 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 for normal hematopoiesis, protein, magnesium, copper and other microelements are needed, of which this product also contains a lot.

This question worries many; information about the dangers of this product can be found no less than about the beneficial properties.

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 great 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 indeed a lot of cholesterol in this product, but no more than in pork fillet.

Even the most strict nutritionists believe that a relatively high cholesterol content is not a reason to completely abandon this 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 entering the animal’s blood, but not all of them must accumulate in it, as many believe.

Modern livestock farming, especially abroad, widely uses hormones and antibiotics, as well as feed with various additives. In the United States, research has 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 the consumption of 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 were on natural grazing (grass) contains less cholesterol, more vitamins, unsaturated fatty acids and others useful substances. In this regard, in Lately The number of so-called eco-farms has increased everywhere, where animals are raised in environmentally friendly conditions, without the use of drugs that accelerate the growth of the individual.

If the liver of an old animal comes to your table, raised by unscrupulous farmers using compound feed, using medicines, then it will not only be tough and tasteless, but also not particularly healthy. 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 the purchase.

Medical contraindications

This by-product is contraindicated in Wilson-Konovalov disease. In this case, this is not due to high cholesterol content, but to the fact that high concentration copper, the metabolism of which is impaired in people suffering from this disease.

How to choose a good beef liver?

In fact, choosing a young liver that will be truly useful is not so difficult, since the quality of the product is indicated by its appearance. In some places in the markets you can find for sale not only beef, but also veal liver. The latter, after cooking, turns out softer and more tender, but contains more fat.

To size internal organs you can judge the age of the animal, so if you want to purchase 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 of light brown (usually calf liver) to dark red, sometimes even with a cherry tint, its color should be uniform. Too much dark color liver indicates the venerable age of the animal. The surface of the product should be smooth, shiny, even (not lumpy) and not sticky - the liver that has been sitting becomes dull and a sticky coating appears on it.

The liver cut should also be uniform with a small amount pores, no foreign inclusions should be visible on it, only a cut of the vessels. If, when pressing on a piece, scarlet blood oozes from the cut, then the product is definitely fresh, but on the second day after slaughter you will not see this. After pressing, pits remain on the lying liver. If a light liquid oozes from the cut, then it is most likely water, in which unscrupulous sellers soak offal to extend its shelf life. Based on this, we can conclude that either blood should ooze from the liver slice or nothing.

If you have the opportunity and desire, then you should definitely smell the product; the smell should not be sharp or unpleasant, it should be slightly sweet, almost the same as that of fresh beef.

The liver is good for health. But which liver tastes better: pork or beef? Which one is healthier and gentler? Let's try to understand these issues.

Taste and color

Everyone is different, and it would be strange to judge someone based on their eating habits. However, why are pork by-products, to put it mildly, not in the place of honor on store shelves? Than pork worse than that what about beef? There are enough liver lovers who note the taste and tenderness of this product, regardless of its origin. However, such a gradation does not seem entirely fair. How can you figure out which liver tastes better: pork or beef? Why do they differ in price? And does such a product require special culinary skills?

Let's go through the composition

It must be said that liver is one of the most beloved and, accordingly, consumed by-products. Humans eat the liver of various animals: birds, cows, pigs and even fish. Each type is good and nutritious in its own way. The liver always contains a lot of useful substances and complete proteins, amino acids, iron, copper, as well as a lot of water and only 2-5% fat. The composition of the liver is very harmonious, and therefore it is quickly absorbed by the body. In particular, amino acids affect the digestibility of proteins and calcium, which “inhibits” the development of osteoporosis, atherosclerosis, the occurrence of strokes and heart attacks.

A lack of an amino acid such as lysine can cause impotence. And a small amount of tryptophan affects the quality of sleep and provokes anxiety states. A “combo” of methionine, choline and folic acid prevents the formation of tumors, and thiamine protects the body from negative consequences smoking and alcohol abuse. Plus, the liver is rich in phosphorus, magnesium, zinc, sodium, calcium, vitamins B, D, E, K, as well as β-carotene and ascorbic acid. The latter, by the way, has a positive effect on the functioning of the kidneys and brain. So the choice of offal is correct in any case, but which liver is better: pork or beef? To answer this question, you need to focus on these varieties.

IN chain stores the price per kilogram of beef liver fluctuates around 260 rubles. A little expensive, but the product is really useful due to the high content of vitamins A and B, as well as others important microelements. This product is especially good for the prevention of diabetes and atherosclerosis. The abundance of chromium and heparin, which are responsible for blood clotting, makes it possible to include beef liver in the diet of people suffering from overwork or recovering from an illness. And due to folic acid in the composition, the product can be recommended for children and pregnant women.

The price of pork liver in stores is around 190 rubles per kilogram. Why is pork liver cheaper than beef liver? After all, it is also healthy, but in terms of the content of vitamins and microelements it is still slightly inferior to beef. It is also a little lighter in calories. The abundance of glucocorticoids in the composition makes pork liver a unique product during treatment inflammatory diseases. This by-product is also indispensable for anemia and hypothyroidism. So it’s much more difficult than it seems to answer the question of which liver is better: pork or beef. First, it would be good to discuss the possible harm from consuming liver.

but on the other hand

Despite all the usefulness of the two types of offal, its excessive consumption can harm the body. The liver contains extractive substances that should not be consumed by older people. Also at risk are persons with increased content cholesterol in the blood, since 100 g of liver contains almost 200 mg of cholesterol. Everyone knows that its excess can lead to angina, myocardial infarction and strokes. In a conversation about how pork liver differs from beef liver, we can mention one common feature. Only liver obtained from healthy cattle that was properly fed is suitable for food. If livestock was raised in environmentally unfavorable areas, then there is a risk of various diseases.

Choice of the fair half

So, which liver is healthier: Still, more people prefer the first option. Representatives of the fair half of humanity especially love beef liver. After all, this type is leaner and at the same time tender. Beef liver does not have foreign odors. It contains no more than three percent fat and only 120 kcal per 100 g. So the product can safely be classified as dietary. Beef liver helps in the treatment of iron deficiency anemia. The body quickly absorbs the form of iron contained in the liver, and therefore the level of hemoglobin rises. The abundance of protein strengthens the body during increased physical activity, and B vitamins normalize the functioning of the nervous system. When purchasing, pay attention to the total weight of the liver. If it is lighter than two kilograms, then it belonged to a calf. This liver is more tender, tastier and healthier.

Doctors' choice

The vast majority of culinary specialists consider beef liver to be better, but pork liver also has its connoisseurs. This product is chosen not only by culinary specialists, but also by doctors who appreciate its benefits for the growth of hemoglobin. In addition, pork liver is indicated for patients diabetes mellitus and atherosclerosis, as well as persons with visual impairments. Pork liver has slightly less calories - only 109 kcal per 100 g. But it also contains more fat, so it is a slightly less dietary product. The key point in choosing which liver tastes better: pork or beef, there may be purine bases in the composition of the pork offal. Because of them large quantities is formed uric acid, which provokes the appearance of gout. Accordingly, not the most pleasant aroma. To many people it seems specific. To get rid of the aroma, you have to spend a lot of time on heat treatment. So, in the question of which liver tastes better, pork or beef, the answer remains ambiguous, since it all depends on the processing method.

Hastily

How to fry pork liver if you bought it for the first time and haven’t tried it yet? If desired, you can remove the film from the edges. Cut it into thin slices and soak in the prepared dressing. Milk removes the specific aroma very well, then pour over the meat tomato juice with seasonings and garlic. Now simmer for about 30-40 minutes. Lovers of juicy taste will find another option for frying pork liver useful. In this case, while the offal is soaked in milk, it is necessary to cut onion and fry it with chopped carrots. Now add liver, salt, pepper and suneli hops to taste. When serving, add natural yoghurt topping with mustard and garlic to the liver. Bon appetit!
