People think that red-shelled eggs are more nutritious than white-shelled eggs, and they tend to choose red-shelled eggs when buying them.
In fact, this understanding is wrong. From a scientific perspective, whether it is a red-shell egg or a white-shell egg, the nutritional value is almost the same.
So, why are there red and white? It is mainly caused by different chicken breeds and chicken feed.
In the past, brown eggs were laid by so-called wood chickens, while white eggs were laid by leghorn chickens, commonly known as foreign chickens. Brown eggs have thick green eggs, while white eggs have thin green eggs. People think brown eggs are highly nutritious.
But today’s brown eggs are not necessarily from chickens. The brown eggs from chicken factories are mixed with other things in the chicken feed, so the egg skin turns red. The nutrition is the same as that of white eggs, but because people like brown eggs , the price can be increased. This is a means of adding value. Therefore, it is no longer necessary to buy brown eggs from chicken farms.
The nutritional value of brown and white eggs is roughly the same. The former has a slightly higher fat content, while the latter has a slightly higher protein and vitamin A content. In comparison, the only advantage of brown eggs is that their shells are thicker and more durable for storage.
After conducting research on this matter, relevant experts at home and abroad believe that red eggs and white eggs have similar nutritional contents. Now compare the main nutritional components of red and white shell eggs as follows:
①Protein: White shell eggs are about 0.75% higher than red shell eggs.
② Vitamins: Vitamin A, vitamin B1, and vitamin B2 in white-shell eggs are slightly higher than those in brown eggs.
③ Fat: Red-shelled eggs are about 1.4% higher than white-shelled eggs.
④Cholesterol: Red shell eggs are about 0.8% higher than white shell eggs.
Apart from this, other nutrients of the two are almost equal. According to the above comparison, it can be seen that although the main components of red and white shell eggs are different, the difference is not big.
