The next time you buy eggs, bring in two sets; one from a store and the other fresh off a local farm. If you look closely, you will notice that there is a difference in the color of the yolks.
The eggs from the local farm are more likely to have darker yellow yolks, while the other lot from factory farms will have lighter colored ones. This change in color is due to the poor-nutrient diet that is fed to factory-farmed chickens, and that’s why they produce inferior yolks. Ideally, a chicken should be able to produce eggs that have darker yolks (which is a direct result of the quality of food they’re fed). However, sometimes factory farmers artificially darken the color of the yolk by feeding the chicken naturally-occurring plant pigments.
Egg yolks contain 100 percent of the fat soluble vitamins A, D, E and K, as well as all the carotenoids, lutein and zeaxanthin. So be sure to purchase good quality eggs, so you can get the most out of these nutrients.
