Remember a few years ago when we were all going to have heart attacks and die if we ate the whole egg? Restaurants started adding egg white omelets to their menus and everyone felt like they were eating healthy when they left out the yolk. As with most well-hyped food fads we later found that the egg yolk is actually good for us. Imagine that, God didn't give us egg yolks to kill us but to nuture us! Well add that yolk back into your omelet unless your doctor tells you otherwise (always follow doctors orders and not internet articles if you have doubts or questions). Here's why you should eat the whole egg; almost half the protein is in the yolk, yolks are rich in vitamins and are one of the best sources of choline. Choline is a nutrient that's important for brain health and may lower the risk of heart disease and cancer.
