We’ve upgraded the ever-popular avocado toast with homemade gluten-free bread and a poached egg, on top, for added protein and nutrients. We now know that the yolk contains most of the egg’s nutrients, so it’s about time we change your mind about egg yolks (if we haven’t already)! The yolk contains choline, which is essential for the functioning of all cells, especially brain cells. Egg yolks also contain antioxidants; B vitamins, including B12; vitamin A; iron; selenium; biotin; phosphorous, and other various trace nutrients. Egg whites, alone, lack many of the nutrients that are found in the yolk, a nutrition powerhouse.
