The taste and nutritional value of eggs depend to a large extent on the way the hens are fed. The best are rural eggs from chickens kept in natural conditions.
Eggs were once thought to be very nutritious and healthy, and they lost their reputation because of cholesterol, but recent studies show that if a man likes eggs, he can eat them, though not at will. Check what nutritional values and how many calories (kcal) have eggs.
In the 1970s, dieticians declared war on them, whether it was healthy or not. There was a food cholesterol in the egg yolk. Scientists saw the connection between the amount of eggs eaten and the high level of cholesterol in the blood and as a result of atherosclerosis .
Today’s views have changed a bit: it turned out that the greater relationship with atherosclerosis is to provide the body with saturated fatty acids than cholesterol, but that does not mean that we are allowed to eat eggs completely without restrictions.
Eggs are primarily a source of wholesome protein, easily digestible by the body.This is a standard protein, containing all the amino acids, including essentials, which the body can not produce itself, and in the right amounts.Therefore, in 1965 the World Health Organization (WHO) considered them as a model for measuring the proportion of amino acids in products.
Egg weighing 56 grams provides as much as 7.03 grams of protein. Paradoxically, the yolks contain more proteins than chicken egg whites.
Eggs are also a rich source of vitamins A, E, D and K and B vitamins and minerals, phosphorus, potassium, sodium, calcium, iron, magnesium, copper, zinc, selenium.
In yolk is beta-carotene and lutein, which protects eyes from harmful UVA and UVB rays, prevents macular degeneration and improves vision.
Eggs have a beneficial fat composition. For 5 g of fat contained in one egg (yolk) only 0.1 g are bad saturated fatty acids, but many essential fatty acids in the body, including omega-3 fatty.

Eggs and blood cholesterol levels
It is widely believed that eating eggs increases the level of cholesterol that contributes to the development of atherosclerosis. Also, in 100g eggs there are up to 372 mg of cholesterol.1 However, in eggs you will find a whole range of vitamins, minerals, essential fatty acids and lecithin. They will work advantageously on the level of good HDL and reduce the bad effect of LDL.
Eggs, however, are a unique product in this aspect. Other sources of cholesterol in foods such as
livers, sausages, salami, cheese, cheese, and blue cheese no longer carry all these beneficial ingredients. On the contrary – they are also a source of saturated fatty acids, of which our liver will produce this cholesterol.
Eggs can be allergic
Eggs are the most common cow’s food allergen, which may even cause anaphylactic shock, so you should not feed them before the age of 1 (especially for babies prone to allergies and genetically burdened with the disease).
There is a perception that a boiled egg is safe for allergy sufferers, because proteins contained in it during the long heat treatment are denatured.
It’s a myth! The most allergenic proteins – ovalbumin and ovomucoid – do not change their structure, the yolk itself also contains allergenic proteins, only slightly differently constructed, so the risk of sensitization is lower.
The healthiest eggs – from green-legs
“Zielononożki” is an old Polish breed of chickens, once popular because of the ease of breeding. At the end of the 20th century, when hen farms appeared, partridge green-legs were growing less and less for economic reasons.
They only carry 140-180 eggs a year, while leghounds – every day.In addition, this second breed can be grown in cages, and green-legged must have a catwalk in the open air.
They are therefore only suitable for organic farming. Currently, the interest in eggs from these happy backyard cockches is growing, because they contain 30%.less cholesterol. That is why you can buy them not only at the market or at the farm, but also at some stores. Unfortunately, they are more expensive.
Eggs help hangover and strengthen bones
Eggs relieve hangover symptoms because they contain cysteine - an amino acid that speeds up metabolism and removal of toxins.
Egg shells are a rich source of easily digestible calcium, which is why they were parboiled and ground to a powder used in the prevention of osteoporosis. To this day, some still use this method of strengthening bones and teeth, adding 1 g of crusted crusts to dishes daily.
