In Latvia chicken eggs are divided into four parts or according to the method of laying hens. Eggs from organic hens in Salt, the first – eggs from free range hens, the second – eggs from hens kept in barns and the third – eggs from hens kept in cages.
Twelve different egg samples – three from each category – were handed over to the BIOR laboratory of the State Scientific Institute to determine the amount of protein and fat in the eggs of hens raised under different conditions.
According to program specialists, eggs are a good source of protein and are an important part of the body that provides various important functions such as participating in the growth and regeneration of cells and tissues in the body. But if the diet is high in carbohydrates and fats, our body can use protein as an energy source.
Exhibition analysis shows that almost every egg contains the same amount of protein, but most of them are found in nests and barn eggs. Assuming they weigh 6.4 grams or 75 kilograms per person, they are the twelfth protein in the recommended daily allowance. Organic and free range hen eggs contain slightly less – about 6 grams of protein.
“Caged hens may have an even higher protein content, but in general this difference in protein content is very small, so unfortunately we can not say that this is the main reason you should buy, for example one or the other chicken egg, the difference is actually 0, 1 – 0.3 and that is very important for such a large part, ”explains nutritionist Sandeeja Aplata in the results.
Eggs contain not only protein but also fat. Eggs are high in fat and are considered a good source of unsaturated fatty acids and should be taken in moderation. Unsaturated fatty acids are essential for our internal organs, nervous system, muscle growth and all cell regeneration.
The average fat content of each egg tested was about 4.5 g. This time the fat was contained in two organically produced chicken egg samples but the same amount as the caged chicken eggs. The lowest fat content should be in an organic and free range egg sample and in a caged egg sample.
The nutritionist reveals that he is amazed at the results: “This is the part that struck me the most. By buying eggs.
Eggs also contain vitamins, minerals and antioxidants. For example, it contains essential amino acids, folate and riboflavin, choline as well as vitamins A, B12, D and K.
In 2019, the University of Latvia was studied by the Balticov Company. It analyzed all four types of eggs and found that free range hens had slightly lower levels of vitamins A and E but more vitamin D and biotin than nest or barn hens eggs. Meanwhile, barn eggs contain the least amount of vitamins B1 and B9.
Summarizing all the data obtained from the exhibition, it can be concluded that there is not much difference between free-range or organically reared hens in nest or barn eggs. All are safe to use, and there is no evidence that only a specific group of eggs contain significantly more or less nutrients, vitamins or minerals.
