Eggs, the old standby breakfast food, are a fantastic source of protein. But figuring out what kind of eggs to buy is becoming more and more daunting. Labels boasting free-range, cage-free and fortified might leave you scratching your head -- luckily The New York Times in shedding some light on what they all mean. Here are a few pointers:

• Cage-free means the bird was kept out of a cage, but this doesn't mean they ever saw the light of day
• Free-range means they had regular access to the outdoors, but 'outdoor' could mean a parking lot.
• Pasture-raised means that at least some of their diet was natural (like greens and bugs.) But there's no regulation on how much of their diet needs to be natural.
• Animal Welfare Approved means they spent all their time outdoors in a pesticide-free pasture. They are bathed and not fed any animal byproducts.
