Due to their rich composition and nutritional value, chicken eggs are included in all he alth-improving diets.

Chicken egg size

As a rule, its parameters will depend on the breed of the laying hen, its age, complementary foods and conditions of detention. For example, if a chicken constantly received less of any nutrients, then this fact will certainly affect the quality of the egg. The bird will be much worse rushing. If laying hens are fed natural feed without the addition of antibiotics, then the eggs they lay will be classified as organic products and are much more valued.

Large eggs are laid by hens over eight months old. Young birds produce small eggs. The quantity and size of this product also depend on the breed of the laying hen. There are so-called egg hens, amongwhich are distinguished by the following breeds: Leghorn, Highsec Brown, Loman Brown and High Line. And also good large eggs are obtained from he althy birds, which are kept in favorable conditions.

How to choose eggs

Many people pay attention primarily to the size and condition of the shell. Experts advise evaluating the product according to the variety, storage condition and GOST. It is believed that the most useful are eggs purchased on the market from small producers. There is an opinion that large poultry farms feed layers with unhe althy food, which contains antibiotics.

In order to protect yourself and your loved ones from such a purchase, it is best to find a farmer who inspires confidence and regularly purchase products of his own production from him. Very often, the breeder goes to meet regular customers, shows his farmstead to customers and talks in detail about the conditions for keeping birds.

Storage and labeling

According to GOST, chicken eggs are marked as follows: the Latin letter D means that the shelf life of the product is only seven days. This egg will be considered dietary. The table product is marked with the letter C, and its shelf life is twenty-five days. The weighteggs of the first category should be about sixty grams with the shell.

What is the yolk made of

The chemical composition of the yolk of a chicken egg and protein are somewhat different from each other. For example, it contains a huge amount of vitamin B12. The yolk has a rich color due to the presence of vitamin A in it. This important element is simply necessary for healing the skin, eliminating peeling and healing wounds. The lack of this vitamin leads to premature aging and the formation of wrinkles. In addition, thanks to vitamin PP, the walls of blood vessels are strengthened and their elasticity increases. The brighter the yolk, the more vitamin A it contains, which means that its benefits are much higher.

As for other important elements, it boasts substances such as choline and melatonin. Moreover, the greatest amount of these substances will contain the yolk of a raw egg.

Protein composition

This unique product has absolutely no fat, but is the most important source of protein (protein). It contains a lot of trace elements, among which calcium, phosphorus and iron are distinguished. Amino acids that supply oxygen to brain cells are present in the protein of a chicken egg. Unlike the yolk, the protein is undesirable to eat raw. It contains an enzyme that destroys gastric juice. In addition, this product is a fairly powerful allergen, which also adversely affects human he alth. It contains only forty-eight kilocalories.

Eggs and cholesterol

Very often you can hearthe opinion that eggs are a supplier of a huge amount of cholesterol, which is deposited on the walls of blood vessels. In fact, this product contains beneficial cholesterol, which is a building material for the liver. However, the intake of cholesterol from foods is not at all necessary, since it is perfectly produced by the body itself. Therefore, without it, a person will not be left.

Unfortunately, very often he althy products contain harmful substances along with vitamins and microelements. For example, chicken yolk, which is known to be rich in extremely important elements, has quite a lot of cholesterol. People who monitor their he alth, as a rule, carefully calculate the amount of harmful and undesirable components. When it is not possible to completely abandon eggs, then the use of other products should be reduced to a minimum. Thus, if a person eats two yolks during the day, then he should limit the consumption of milk or meat so as not to exceed the daily intake of cholesterol. After all, the body can easily cope with a small amount of it.

Harm eggs

Unfortunately, many supermarket eggs contain antibiotics. They can be partially destroyed by heat treatment. In addition to antibiotics, these foods also contain nitrates and other poisons. There is also a risk of Salmonella infection. This is a rather unpleasant disease, which sometimes ends in death. In addition, there is a category of people who are not recommendedconsume eggs. These include, first of all, allergy sufferers and people with problems of the digestive tract. In psoriasis, eggs cause an exacerbation of the disease. Cardiovascular patients should be careful not to consume this product as much as possible due to the presence of cholesterol.
