What is the nutritional difference between ordinary eggs and free-range eggs?

The nutritional difference between ordinary eggs and free-range eggs is that the content of mineral elements such as calcium, zinc, copper, and magnesium in ordinary eggs is higher than that in free-range eggs, while the content of fat, vitamins, cholesterol and other ingredients in free-range eggs is higher than that in ordinary eggs. There is no obvious difference in other nutrients.

Why are the yolks of free range eggs white?

It may be related to the feed and food fed to native chickens. In the process of egg yolk formation, the composition of the feed will affect the color of the egg yolk. If the pigment content in the chicken feed or the food the chicken eats is low, the color of the egg yolk will be lighter, causing the egg yolk to be white.

Are free range eggs really more nutritious?

Not necessarily.

As long as the eggs are produced strictly in accordance with the requirements and no unhealthy additives are abused, the nutritional value of free range eggs and ordinary eggs is actually similar. Generally, the feed in regular chicken farms is scientifically proportioned and the nutrition is very comprehensive. It’s just that they don’t have the natural flavor of free range eggs. Free range eggs taste better, but the nutritional value is not much different from that of ordinary eggs.
