Are dark-shelled eggs healthier than whites?

Can the idea of ​​"not judging a book by its cover" work for the eggs we eat too? Explaining: Many people consider dark-shelled eggs healthier and more nutritious than whites. But are they really?

Well, it all depends on the origin of the egg, not exactly the color of its exterior. White eggs are usually the result of industrial production and therefore less healthy than those of farms. But that does not mean that every white egg follows this rule.

But what determines the color of eggshells?

The color of eggshells is determined by a combination of breed and genetics, and the conditions under which chickens are reared do not interfere with this. You can often tell if the eggs will turn white by looking at the lobes of a chicken's ears - that colored skin that is next to its head. Chickens with white lobes usually lay white eggs, while chickens with brown or reddish lobes often lay brown eggs.

However, there is no scientific evidence that any breed of chicken can lay more nutritious eggs than others, but the condition of the animal can affect the nutrition of its eggs.

Free chickens produce more nutritious eggs

Mother Earth News recently tested eggs from 14 flocks across the country, whose chickens had frequent access to fresh pasture, and found that these eggs were nutritionally superior to those sold in grocery stores.

Free chicken

By comparing the nutritional quality of both types of eggs, they found that those resulting from a more natural and free rearing had 1/3 less cholesterol, 1/4 less saturated fat, 2/3 more vitamin A, 2 times more omega- 3, three times more vitamin E and 7 times more beta carotene.

Yet another study conducted by Consumer Reports found that chicken nutrition also directly impacts the nutritional quality of their eggs. Those birds fed vegetarian diets tend to lay eggs with more vitamins than those fed conventional diets.

But in the supermarket we also have brown eggs. And now?

Given the above information, it is really tricky to know if that egg you are about to buy is healthier if the only criterion is the color of its shell. Because of this, it is worth looking at the packaging and see if there is information on how the chickens that produced that batch of eggs are raised: if free, or confined. In the absence of such warnings, it can be assumed that those eggs are the result of industrial production.

In conclusion, white eggs can be as healthy and nutritious as brown ones. It all depends on the conditions under which chickens were raised (with access to free range, exercise and sunlight, for example), and whether they were fed a proper diet.
