Many people prefer to choose a brown egg, as they consider it to be healthier or more natural. Others think that white eggs are cleaner or taste better. But while the most common are brown or white, there are also blue-green eggs, among other various shades. The Gétinaise or Leghorn or Bourbourg hens lay eggs with white shells, while the red Marans hen lays eggs with brown shells.
The different colors of the eggshell come from the pigments of the hens. What gives brown eggs their color is called protoporphyrin IX, and it is made up primarily of heme, or the components of hemoglobin, which give your blood its red color.
So, here is the answer. In short it is that the color is determined by the chicken and white eggs can be just as healthy as brown eggs.
Although genetics is the main factor that determines the color of the eggs, there are other factors that could also have some influence. Generally, brown-shelled eggs come from hens with brown plumage, and white-shelled eggs are produced by white-feathered hens.
The influence of the bird’s environment
The environment also determines whether the egg she lays will be healthier, regardless of its color, be it brown or white. But all eggs are nutritionally very similar, regardless of their size or color. Brown eggs and white eggs contain many high-quality vitamins, minerals, and protein and are less than 80 calories each.
Different colored eggs have been scientifically studied and compared in search of different properties. The conclusions reached by the researchers indicate that it cannot be said that there are significant differences in the composition of the eggs due to the color of their shells.
Other influencing factors
There are also other factors that can affect the nutritional content of an egg. Hens that are allowed to move in the sun contain 3 to 4 times the amount of vitamin D, which is found in the eggs of laying hens that live in cages.
Chickens that are fed a diet rich in omega-3 fatty acids produce eggs that contain much higher than normal levels of omega-3s. The same happens with the nutrients that the rations contain, as well as the hygiene and health of the place where they live.
There is, therefore no nutritional difference between brown and white eggs. The egg is a healthy food, although its way of cooking has a substantial influence. Avoid eating fried eggs, especially with butter, and opt for boiled eggs, which are much healthier.
