Egg Protein: Comparing Whole Egg and Egg White Protein Content and cost to Beans and Meat

  • 2 min read

Eggs are seasonal in price, supply, and demand. Think about Easter, around 61,000,000 dozen or 732,000,000 individual eggs are sold for the Holiday!

The most popular size of an egg is large. The most common package in the United States is 12 large eggs in a carton and the eggs weigh 24 ounces. That’s an average of 2 ounces per egg. At the USDA National Nutrient Database site, it mentions that the shell can weigh on average about 12% of the 2 ounces. They compute the edible portion of the egg weighs about 50 grams or 1.766 ounces. For weights and measures, the eggs must weigh 24 ounces minimum, so it is always possible your eggs will weigh more.

The price fluctuates more than most other protein rich foods. In 2015, I’ve seen a dozen large eggs for as little as $0.69 and as much as $3.69 per dozen.

So how does the price of an egg compare to the price of other protein sources? Let’s use the price at the Jay C Plus Grocery store as of 8/28/2015, in Bedford, IN. There is a download of the Nutrient data from the USDA available at this link. I used their calculator to calculate the nutrition for close to 50 grams of Whole Large Eggs, Egg Whites, Tuna, Canned Navy Beans, Peanut Butter, Chicken, and Ground Beef. Please remember that might not be a common amount that you eat. It would be equivalent to a little more than 3 Tablespoons.

8/28/15 prices for (all amounts rounded):

  • 12 Large Eggs 24 ounces= $2.69, 24 ounces, Price per ounce $0.11 ($1.69/dozen, Price/ounce $0.070)

Calculating cost per gram of protein (using 453 grams per 16 ounces, 50 grams= 1.766 ounces)
