The yolk itself provides all the cholesterol content of the egg, and almost all of the fat. As a result, it is higher in calories than the egg white, despite the egg white being two thirds of the whole egg. The yolk houses all of the fat soluble vitamins in the egg, and most of the content of other vitamins and minerals which is why it’s also the source of many benefits for health.
