Boiled eggs are the ultimate convenience food. Easy to prepare, eggs contain a natural source of many nutrients, including high-quality protein. While whole eggs contain a significant amount of cholesterol, boiled egg whites contain none.
Calories
One large egg contains between 70 and 75 calories. Boiled eggs contain the same number of calories as raw eggs, but different size eggs contain different calories. Small eggs can have as few as 57 calories, while jumbo eggs can contain about 100 calories. Most of the calories in a large egg, about 55, come from the yolk. The whites contain very few calories, only about 17.
Protein
Boiled eggs contain on average about 6 g of protein per large egg. The amount of protein is roughly equally divided between the white and yolk of the egg. The amount of protein per egg does not change when the egg is boiled, but the structure of the protein does. Heat destroys the three-dimensional shape of egg proteins, making them easier for you to digest.
Cholesterol
Eggs contain a tremendous amount of cholesterol, about 211 mg per egg on average, but this figure can range from 156 mg to 274 mg, depending upon the size of the egg. All of the cholesterol comes from the yolk. The whites do not contain any cholesterol.
Other Facts
Boiled egg whites contain 54 mg of potassium; 2.3 mg of calcium; and 55 mg of sodium, which is 2 percent of the daily recommended value. Boiled egg whites contain no dietary fiber.
