The nutritional value of eggs cannot be denied. They are loaded with protein and are, as such, used as a measure for other proteins. What's more, they contain almost every essential vitamin and mineral humans need.

Egg yolks contain a high percentage of cholesterol, and people watching their cholesterol should avoid them. But normal, healthy, active humans can, and should, benefit from the incredible egg.

Choosing Your Eggs

When possible, look for organic eggs from free-range chickens. They are regulated to a certain extent by the USDA. No antibiotics or hormones are allowed, and the birds are provided with access to the outdoors. Eggs have a tremendous shelf life. By the time they get to your grocer, they are usually one or two weeks old. They will last in your fridge another three weeks. The shell, which is very porous, allows odor and moisture to pass through. Over time, the yolk and white become thinner. Thicker, fresher egg whites and yolks are preferable for recipes that require the eggs to be whipped.
