31. The Protein Content of the Yolk and Albumen is the Same

This was certainly a surprise to us! Each egg albumen and yolk contains 3 grams of protein.

So, while we typically associate egg whites with protein, they have no nutritional benefit over their yellow counterpart.

The main distinction is in the number of calories. A single yolk contains 3 grams of protein for 60 calories, whereas an egg white contains 3 grams of protein for only 15 calories.

By omitting the yolk, you can get the same amount of protein for fewer calories.

However, because of the high levels of beneficial micronutrients in egg yolks, we suggest you eat them.

Hens are still frequently kept entirely indoors, either in large barns known as aviaries or in smaller “enriched” cages that allow for some normal habits.

Although many cartons advertise their eggs as hormone-free, this is a standard claim. It’s the same as saying water is wet.

This infection caused a genetic mutation that caused a formation of a pigment known as biliverdin, causing the chickens to lay green and blue eggs!

35. The Thickness of an Eggshell is Determined by the Age of the Laying Chicken

Brown eggs have thicker shells than white eggs, contrary to popular belief. In reality, the thickness of an egg is solely determined by the age of the chicken: younger chickens lay eggs with thicker shells, while older chickens lay eggs with thinner shells.

This thickness occurs regardless of chicken breed.

Blue, green, and brown eggs all have a more distinct and interesting appearance than white eggs.

Simply because white eggs lack color doesn’t mean they’re nutritionally deficient.

42. You Can Determine the Age of Your Eggs by Assessing Their Buoyancy

Eggshells have a porous structure. They allow air to pass through. As eggs age, they absorb air and form air pockets.

43. The Best Eggs for Poaching are Grade AA

According to USDA egg classification guidelines, AA quality eggs have “clear and firm” egg whites, while A quality egg whites are just “clean and reasonably firm.” Fresh AA eggs are the ideal eggs for poaching since they have the firmest egg whites.

48. The White Sticky Thing shows a Good Egg


Chalazae are the curly, white strings that gather at the edges of egg yolks.

They’ve basically twisted membranes that link up the yolk to the shell’s tip. These fibers are not only fine to eat, but their presence is a good sign of the egg’s freshness.

49. American Eggs Should be Kept Cold

Because eggs are laid through the same passage as feces, salmonella can be found on the outside of an eggshell.

To reduce the risk of salmonella, the USDA mandates that all American eggs be washed.

Because this washing reduces the natural lining that defends the egg from infection, known as a “bloom,” we must then refrigerate our eggs to keep them chilled and reduce the risk of bacterial infection.

As a result, eggs aren’t on our list of surprising foods you shouldn’t keep in the fridge.
