Eat egg yolk or no?
Eat the whole Eggs, including the yolk (not just egg whites)
Most people know that eggs are one of the highest quality sources of protein. However, most people don't know that the egg yolks are the healthiest part of the egg... that's where almost all of the vitamins, minerals, and antioxidants (such as lutein) are found in eggs.
The egg yolks contain more than 90% of the calcium, iron, phosphorus, zinc, thiamin, B6, folate, and B12, and panthothenic acid of the egg.
The yolks contain ALL of the fat soluble vitamins A, D, E, and K in the egg, as well as ALL of the essential fatty acids. Also, the protein of whole eggs is more bio-available than egg whites alone due to a more balanced amino acid profile that the yolks help to build. Just make sure to choose free-range organic eggs instead of normal grocery store eggs. Similar to the grass-fed beef, the nutrient content of the eggs and the balance between healthy omega-3 fatty acids and inflammatory omega-6 fatty acids (in excess) is controlled by the diet of the hens. Chickens that are allowed to roam free outside and eat a more natural diet will give you healthier, more nutrient-rich eggs with a healthier fat balance compared with your typical grocery store eggs (that came from chickens fed nothing but soy and corn and crowded inside "egg factories" all day long).
