Are Egg Shells Edible?

Egg shells are edible, and because they are made of calcium carbonate, consuming them might actually contribute to bone strength. As much as 12% of an average egg’s weight is made up of its shell. There is a potential for bacterial contamination on an eggshell, so people who have compromised immune systems are advised to avoid consuming raw eggshells. Eggs can be boiled to make their shells easier to remove and to crush before eating. Hens can produce eggs with shells in a variety of colors, such as white, dark brown or blue. Eggshell color has not been found to affect taste or safety, but in general, only eggs with white or light brown shells are sold commercially.

More about eggs:

  • A hen lays about 260 eggs per year.
  • Although chickens are the most well-known poultry for laying edible eggs, turkeys also lay eggs. Turkeys tend to be protective of their eggs, however, which makes their eggs more difficult to collect.
  • China produces the most eggs — about 390 million per year, or half of the world’s egg supply.

Salmonella would not be a problem with boiled egg or most cooked eggs. These guys get destroyed above 55 degree celsius. Drinking raw egg sure could pose problems for salmonella, but generally the contamination rate is low, but I would still advise you not to consume them raw.

I love eggs. They have hundreds, if not thousands of uses, especially when you're cooking. The next time you're low on food in the kitchen, if you still happen to have some, you'd be surprised at what you could make out of them. From ham and egg sandwiches, to to grits and scrambled eggs, the possibilities are endless.
@RoyalSpyder - Though the egg whites are full of protein, and are the healthiest parts, the yolk is very high in fat. I don't know how much this would help, but to avoid the risk of salmonella, only aim for the eggs' whites. They may not taste the best when sloshed around in your mouth, but they sure have a lot of benefits.

Speaking of eggs, does anyone know if you can get salmonella from drinking raw eggs? Lately, I've been doing some serious workouts, and have heard that drinking raw eggs is good for protein. However, I don't want to run the risk of getting sick. Does anyone have some advice?
