At the grocery store you are now faced with a large refrigerator section full of different egg cartons bragging about being cage-free, organic, brown shell… and the price reflects it. Eggs are an awesome source of vitamins and minerals and protein. A single large chicken egg (on average about 2 ounces) will have about:
- 70 calories
- 6g of protein
- 4g of fat
- 0g of carbs
Beyond the four key nutrition points eggs also have notable amounts of other vitamins and minerals.
- 169mg of choline
- 50 International units of Vitamin D
- 0.5 nanograms of Vitamin B12
White Shells vs Brown Shells
There is a tragic myth that is widely spread that says brown shell chicken eggs are better for you than white shell chicken eggs. The two different colors simple come from different chicken breeds. Both white shell eggs and brown shell eggs have the same nutrition.
Free Range vs Cage Free vs Pasture Raised
Free range, cage free, and pasture raised are all ways to describe how the chicken that produced the egg lives.
Free range means the chicken is able to go in and out of its home as it pleases.
Cage free insinuates that the chicken is able to roam in a large green pasture. It really just means that the chicken isn’t in an individual coop. That could mean it is in extremely tight quarters with other chickens in a large, open barn.
Technically, Pasture Raised isn’t a legal term. It has the same authority as the word natural; it sounds important but has no true meaning to back it up. Legalities aside, when a carton of eggs are labeled as pasture raised it is supposed to mean that the chicken spent most of its life freely roaming a pasture with the ability to retreat indoors when it wants.1
The bottom line is that the type of living of the chicken may not play a role in the egg’s nutrition but if you care about the quality of life of the chicken I would support farmers producing free range eggs.
Organic Eggs
Another faucet to consider is whether you want organic eggs or not. In order to be classified as organic a farmer must abide by the standards set by the USDA. The chickens feed must be:
- Free from herbicides, pesticides, and commercial fertilizers
- Have year-round access to the outdoors
- Cannot have treatment withheld if they get sick
The Grading of Eggs
Have you ever noticed AA, A, and B on egg cartons? That is how the USDA grades their quality. This grading is based off of the quality of the inside of the egg, the appearance, and the condition of the shell.2 Although B eggs do not typically have any major issues they are not usually sold in stores. Eggs that get classified as B grade don’t make it to any type of retailer. They will still be used but in the form of the carton egg whites or used for powdered eggs.
Basically, if you are shopping at your local grocery store you will likely only have the option to purchase A or AA quality eggs. AA eggs are of slightly better quality but there is no large difference to sway you from purchasing one type rather than the other.
What About The Cholesterol?
It’s been said to not consume the yolk of an egg because it has too much cholesterol. That’s a lie. The yolk of an egg does contain 237mg of cholesterol but that is not to be feared for the average person.4 The daily recommended value of cholesterol for an average person is 300mg but someone already facing high cholesterol levels may want to keep it to about 200mg.
You heard that right, you shouldn’t be totally avoiding cholesterol. Your liver actually makes it! It’s necessary for your body to function properly. Cholesterol is used with hormones and vitamins. It also plays a role in building cells.
fun fact: did you know cholesterol only comes from animal products?
If you are someone who has been told by their doctor that they need to work on lowering your cholesterol, I recommend you read my article, Simple Changes To Lower Your Cholesterol.
Frequently Asked Questions
How do eggs with two yolks happen?
While the chicken was in its ovulation cycle, two eggs were releases instead of one.5

Why is the yolk off-colored?
The color of the yolk can sometimes be altered depending on what the chicken eats.
Why is the shell soft?
The shell of an egg can be more soft than usual because it was prematurely laid. The egg was not in the uterus of the chicken long enough to fully develop.
