Many people eat the egg white only disposing the yolk due to a fear of fat and cholesterol. But in doing this, you are throwing out the most nutritious part of the egg! Egg yolk has the highest concentration of nutrients and amino acids required for optimal brain function. The yolk contains 100% of the carotenoids, essential fatty acids, vitamins A, E, D, & K. These fat soluble vitamins support your thyroid, reduce the damaging effects of diabetes, boost your metabolism and immune system, reduce your risk of cancer, encourage healthy bones, teeth and skin, and help you feel fuller longer. In fact the only nutrient missing from an egg is vitamin C.
