Features of protein in cottage cheese
We often hear the statement that cottage cheese is very useful. To the question "what?" many will answer that it is high in protein. But what, in fact, is protein, why does a person need it, is it really in cottage cheese, and how much protein does it contain - these questions can already cause difficulty.
Is it in the product?
In order to understand what the features of the protein in cottage cheese are, it is necessary to find out what kind of product it is. Cottage cheese is obtained from sour milk. As a result of heating, yogurt is divided into two substances - a white curd mass and whey, which is removed by pressing. In some European countries, the result of this process is called cheese, in Russia - cottage cheese. The taste of a high-quality fresh product is very pleasant, delicate, with a slightly noticeable sourness.
Cottage cheese is rightfully in the lead in the list of products necessary for a person. Its benefits are undeniable and due to the composition, including phosphorus, calcium, vitamins A, B, C, carbohydrates, fats, proteins. It is noteworthy that heat treatment does not affect the beneficial properties in any way, so cottage cheese is traditionally used for making cheesecakes, cottage cheese pancakes, dumplings, casseroles, and confectionery. Cottage cheese goes well with berries, fruits, herbs, cucumbers. Often sour cream or cream is added to it.
Protein is an organic substance that is a chain of amino acids.Without proteins, no living organism can exist, since they are a kind of "building materials" for cells, tissues and all organs. The composition of enzymes and hormones also includes a significant amount of protein compounds. And hemoglobin, which is so necessary for providing oxygen to the blood, is essentially a protein. Therefore, it is no coincidence that protein is also called protein. From the Greek language "protos" is translated as "first", that is, protein is just the substance that is primary for life.
The cells of the human body contain thousands of different proteins. Each of them, in turn, consists of twenty amino acids, combined with each other in a huge number of sequences. These sequences (or chains) determine a certain functional load of each protein compound.
The body does not store protein, so it must constantly come with food. Cottage cheese is one of the products in which the much-needed protein is contained in a sufficiently large amount and is easily digestible.
The protein in cottage cheese is called casein. It consists of such amino acids that the body itself is not able to synthesize, but it cannot exist without them:
- lysine - without it, normal growth, tissue repair, production of the necessary enzymes, antibodies, hormones is impossible;
- methionine is the main "building material" for all cells;
- tryptophan is a source of good mood; getting into the body, it is converted into serotonin, which controls the emotional state; depression, insomnia, headache, attention disorder - this is an incomplete series of consequences of low tryptophan content.
Maybe it's all carbohydrates?
The thing is that the functions of proteins and carbohydrates in the body are not identical. Carbohydrates are part of the cellular composition, but proteins are the “builders” of cells and tissues, and carbohydrates are energy sources. Both are important for the normal functioning of the body.
Carbohydrates are also found in cottage cheese, but in smaller quantities than proteins. The high protein content contributes to better absorption of carbohydrates and faster metabolism, that is, carbohydrate metabolism. An almost perfect ratio of these vital compounds is present in cottage cheese.
What is it: vegetable or animal?
Of course, cottage cheese contains animal protein, because this product itself is of animal origin. With a big stretch, you can replace ordinary soy cottage cheese, the so-called tofu, which is obtained by processing soy milk. The color and consistency are almost curd, even the smell is somewhat similar, but the composition and properties are completely different.
Tofu is the richest source of vegetable proteins, no less useful than animals. Like cottage cheese, it contains a lot of calcium. But there are practically no carbohydrates. But soy is a plant that is very easily genetically modified. The inscription on the package “does not contain GMOs” is, unfortunately, not a full guarantee. And the value of such a product is very low.
Content in 100 grams
The amount of protein in 100 grams of the product is from 14 to 18 grams and depends on its fat content. The less fat, the more protein. Before talking about the quantitative ratio of the components contained in cottage cheese, it is necessary to find out how home-made cottage cheese differs from that purchased in a store, and why the fat content of this product is so important.
“Domashniy” is a product prepared at home by the usual fermentation of milk without any extraneous additives. A kilogram of cottage cheese can be obtained from five to six liters of milk. Of course, this is the most valuable and dietary product, safe for baby food, because there is no doubt about its composition and freshness. It should be noted that freshness for cottage cheese is a very important indicator, since of all dairy products it spoils the fastest.
You can get low-fat cottage cheese in a very simple way - put the milk in the refrigerator for several hours and then carefully remove the upper settled layer of cream. Almost fat-free cottage cheese will be obtained from milk passed through a special device - a separator.
You should take a closer look at the composition of purchased cottage cheese: unscrupulous manufacturers can add coconut or palm oil, vegetable fats (which cannot be called healthy), or add starch to add weight to increase fat content. The shelf life is often increased by various chemical additives.
Various levels of fat
According to the degree of fat content, curd products can be divided into three groups: fatty, with a fat content of about 18%, bold - 5-9% and fat-free - 0.1-2%.
Of course, the most delicious and tender will be home-made village cottage cheese made from selected whole milk. In it, depending on the fat content of milk, the fat content can be from 18 to 25%. For 100 grams of such cottage cheese, there are 14 g of proteins. This will be almost 20 percent of the daily requirement. But such a product is very high in calories and can cause weight gain.
The most common is semi-fat cottage cheese (9%), which is made from skimmed milk with the addition of whole.This cottage cheese contains 16-17 g of proteins, which is 20-22% of the daily value. It is recommended to everyone who adheres to the principles of a healthy diet, is not burdened with excess weight and is not currently on a diet.
The best option is cottage cheese with 5% fat. It contains the largest amount of proteins per 100 g - 18 g, and it will replenish the daily intake by 23%, and in addition, it will provide the necessary amount of carbohydrates.
Is low-fat cottage cheese 0% fat?
It is impossible to completely “free” cottage cheese from fats, so the percentage of fat content cannot be zero. As a rule, it ranges from 0.1% to 1.8%.
Nutritionists do not stop arguing about the benefits and harms of fat-free cottage cheese. On the one hand, a person receives the required amount of easily digestible proteins (16 g) with a minimum amount of fat, which allows it to be used in food even by obese people. But on the other - the nutritional and energy value of such a product is reduced:
- along with fats, vitamins A, D, E, soluble in them, practically disappear;
- the lecithin and cephalin necessary for the nervous system also disappear;
- worse absorption of calcium and phosphorus;
- the taste qualities are different from other varieties, and manufacturers can add flavors, fruit or berry fillers “to improve” the taste, which are unlikely to be natural and add benefits to the product.
Which cottage cheese to give preference to is a personal matter for everyone. One thing is certain: this product is necessary for obtaining vitamins, minerals and protein, which is so necessary to ensure the vital functions of the body.
