Is it true that 'brown eggs are more nutritious than white eggs'?

If you go to the supermarket and look at the egg corner, you will usually find white and brown eggs, and even if the number is the same, the brown eggs are slightly more expensive. Many people may think that 'brown eggs are more nutritious than white eggs', but in reality, the color and nutrition of eggs have little to do with each other, according to Inverse, an overseas news site.

Are brown eggs healthier? Science debunks a pervasive myth

'Common brown and white eggs are nutritionally identical,' said Ken Anderson, who studies commercial poultry systems at North Carolina State University. Some may think that the color of the egg shell changes depending on the feed eaten by the chicken, but the color of the egg shell depends on the chicken breed itself, not on the feed or nutrition.

According to Anderson, varieties such as Minorca, which are native to the Mediterranean coast, generally lay white eggs, while Asian and American varieties lay brown eggs. The color of the egg shell is the difference between whether the hen produces or does not produce pigmented secretions on the surface of the egg before spawning, and does not affect the edible parts inside the egg, Anderson said. I'm pointing out.

It's unclear why the myth that 'brown eggs are more nutritious' was born, but Anderson thinks it may be partly due to the birth of a large commercial poultry farm. '(White egg-laying chickens) have historically been better suited for breeding in smaller spaces, which made them easier to work with and handle in large environments,' Anderson said. I did.

While the body of a chicken that lays white eggs is relatively small, the body of a chicken that lays

brown eggs such as white Plymouth Rock is large, so it is more difficult to raise it in a small poultry farm. As a result, chickens that lay brown eggs are often bred in organic or free range poultry farms, and eggs may also have these labels.

Rachel Fine, a registered dietitian in the United States, points out that the idea that 'brown foods are natural and healthy' is widespread throughout society. In general, brown foods are less likely to be considered artificially colored, and it's easy to think that they aren't wasting nutritious parts for their appearance, and Anderson said. I agree with your view.

2010 Mr. Anderson was investigated eggs are lined up on the shelves of the grocery stores who participated

research and, more managed in 2013 that were analyzed born eggs in the situation study in, white eggs and brown eggs nutritional value When comparing the two, the difference in nutritional value between the two was incredibly small. In some cases, one was richer in nutrients and vitamins than the other, but these differences vary from egg to egg and do not reach the 10-25% difference that affects human health.

You may be wondering, 'If white and brown eggs have nothing to do with nutritional value, why do brown eggs tend to be more expensive?' This is because breeds that lay brown eggs are more likely to be bred organically or free-range, and simply 'brown egg-laying chickens eat more feed.' 'Brown egg-laying varieties need more feed to maintain their body,' Anderson explains. 'Probably 5-10% more feed.'

Of course, there are many reasons to prefer brown eggs over white eggs, such as when you're rooting for a local farmer or when you prefer organic eggs that don't contain antibiotics. However, when it comes to nutrients, white and brown eggs are no different, Anderson said, 'When I buy eggs, I only look at the price.'
