Study Shows That Free-range Eggs Contain Higher Levels of Vitamin D

Most egg-laying hens in the U.S. are confined in what’s known as a “battery cage.” This means that hens are kept in cages less than 80 square inches, where they are fed with a meal of corn waste and chemicals and forced to lay eggs. The hens have no room to spread their wings and will never see the sunshine. What’s worse, on the off-chance that a male chick is hatched, he will be disposed of.

Most people know that a reasonable amount of sunshine is good for humans as allows the body to synthesize the necessary amount of vitamin D for calcium absorption and bone development. The same can be said of chickens as well, and the proof is in the eggs.

In a study in the journal Food Chemistry, researchers have found that the egg yolks from chickens allowed to roam outdoors contain 30 percent more vitamin D than those from chickens who are kept in battery cages. Continue reading…
