The color of the shell of egg It differs, mainly between white and brown.
This difference often raises questions to consumers about the nutritional value of the eggs.
However, the color of the egg shell does not affect its nutritional value, but is mainly related to the hen’s genes.
Hens with white wings and white ear lobes lay eggs with white shell, while hens with brown -red plumage and red lobes give birth to brown eggs.
However, it sounds strange, there is a rare breed, such as Track (Araucana), originally from South America and specifically from Chile, which lays eggs in a turquoise color, which is due to specific genes.
Consequently, the color of the egg is determined exclusively by genetics rather than external factors, such as diet or farming conditions.
Although many consumers consider brown eggs more “healthy”, there are no substantial differences in nutritional value between the eggs of different colors. As for egg size, it is mainly determined by the age of the hen, with older hens usually giving birth to larger eggs.
All eggs, regardless of their color, contain high quality protein, vitamins (such as A, B2, B12 and D), minerals (such as iron and zinc) and antioxidants. These nutrients are beneficial to eye health, brain function and protection of the immune system.
On the other hand, the color of the yolk depends mainly on what the hen eats. If its food consists of greens, corn or vegetables, the yolk is yellow or even orange. On the contrary, when its food is more “poorer”, the yolk is lighter in color.
It does not mean, however, that a vibrant yolk is always better, but it is a sign for chicken diet.
The choice of egg, therefore, should not be based on the color of the shell but on other factors, such as its quality, depends on diet and farming conditions (eg free grazing eggs or birds) and its origin.
Moreover, most nutritionists point out that eggs are part of a balanced diet if they are consumed in moderation.
Whether white or brown, the egg remains an excellent source of protein and other valuable nutrients.
