I'm not a dietitian. I'm not a doctor. I'm not a scientist. But I will tell you what I believe to be true: whole eggs are delicious, nutritious, and are a translation of all the goodness in the world.
I must qualify this: I get my eggs from the farmer's market (Creekside Farm and Orchard in WV). I'm not trying to sound all uppity about this, but industrialized eggs cannot even come close to the goodness found in an egg from a healthy and happy hen. I've had the pleasure of meeting some of these girls. They're broads. Happy chickens full of attitude and spunk.
Like I said above, eggs are a translation of all the goodness in the world. If the sun is shining, the grass is growing, and the hen is free to go hunting for bugs, the sun, the grass, and the bugs will all be present in the egg in nutrient form. You see, eggs are more than just sitting down and popping one out. They require great effort to produce within the hen (25 hours from start to finish!). Each layer of the egg is a commentary on the health of a chicken. If she is healthy, the egg will be healthy. It's really quite amazing.
Through the 1970s and 1980s (and even now) people were afraid of the cholesterol in eggs--that they weren't heart healthy. As always, we love to vilify one type of food (carbs! fat! oh noes!!) without knowing the whole picture. You see, cholesterol in an egg does not equal cholesterol in the blood. And I've even read claims that chickens that are pasture raised (i.e. spend lots of time roaming in the grasses) have one third the cholesterol of an industrial egg (among other health benefits).
I pay $4.50 for a dozen eggs. I know that not everyone can afford that. I also know that the cost of a dozen pasture-raised eggs will be cheaper the closer you are to the farm. So poke around and try to find them. I beg of you -- support the deindustrialization of the chicken egg. Not only will these birds live better lives, but we'll see the quality in our cooking and in our overall health.
And if you are afraid of carbs and love french toast, try putting a touch cinnamon in your scrambled eggs. You can thank me later :)
