It is said that the eggs laid by chickens at home are more nutritious than those sold in the market. Is there any scientific basis?

When it comes to native eggs, they are actually eggs born by farmers born in rural areas. Most native chickens are free-range, eat weeds and insects, and usually wander around. Although the eggs laid are not big, they are said to be highly nutritious. So is the nutrition of earth eggs really higher than that of raising eggs? In fact, I personally feel that the nutrition of native eggs produced in rural areas and eggs raised in cities is not so high. Protein and trace elements are abundant in both native eggs and eggs raised in cities, but people will think that native eggs are more nutritious because they eat natural and pollution-free food.

Actually, it's not like this. Some scientists compared the amino acids in natural eggs with those in ordinary eggs. In fact, there is little difference in nutrition between the two, so it is better to say that soil eggs are better than raising eggs. So why are native eggs produced in rural areas more nutritious than those raised in cities? First, the yolk of earth eggs is better than that of chickens. Friends who have eaten earth eggs will find that the yolk of earth eggs is better than that of chickens. In fact, it is impossible to judge which egg is more valuable from the yolk.

The reason why the yolk of earth eggs is yellow is because the earth mainly eats green feed and corn, while the chicken mainly eats feed, so the color of the yolk will be slightly lighter. Secondly, because native chickens live on pure green and pollution-free food, in order to make them lay more eggs, they will be fed a lot of feed to promote egg laying, so people think that native chickens' eggs are more nutritious. Compared with raising eggs, I personally think that native eggs are slightly smaller and the yolk is slightly yellow.

Egg white and yolk are thicker than eggs, and the taste of eggs will be very strong. This is mainly related to the different feeding methods of native eggs, but it has nothing to do with the nutrition of eggs. Don't be blinded by the propaganda of the merchants. From the perspective of nutrition, again, talk more about nutrition. Generally speaking, the yolk of soil eggs is relatively large, or free-range, so we think it must be nutritious.

The main factors that determine the nutritional composition are the breed and feeding time of chickens, and there is little difference between eggs. Native chickens, that is, free-range chickens, are usually more delicious than chickens in chicken farms, so people naturally think of the high nutritional content of eggs, and then think of their great nutritional value. This is a misunderstanding, which is totally hype.
