They have as much as 50 percent of all the protein in the egg, making them a very healthy food source. While the yolk is extremely high in fat, egg whites have practically no fat at all and less than 1 percent carbohydrates. This compound is around 90 percent water and 10 percent liquified proteins such as globulins, albumins and mucoproteins.

Egg whites are created to assist secure the yolk from damage and supply nutrition as the embryo within the egg grows. This area will form regardless of whether or not the egg is fertilized. This is made from secretions from the hen’s oviduct when the egg is passed. Egg whites are also high in protein while being low in fat and calories, making it easy to obtain the nutrients you require without included cholesterol that can be harmful.Įgg whites are the clear liquid within the egg that surrounds the yellow yolk. In fact, there are a number of unsung (and some surprising) superfoods that pack even more protein than an egg.Egg whites contain a variety of vitamins and minerals that help to support your general health. What foods have more protein than an egg?Īlthough immensely versatile, egg protein isn't the only way you can boost muscle mass and blast fat. Why should you eat egg protein?Įating protein-rich foods helps to boost your metabolism, prolong feelings of fullness, and maintain muscle mass to help your body scorch fat, according to a Journal of the American College of Nutrition review.īoth University of Connecticut researchers and University of Missouri-Columbia researchers found that when study participants ate a high-protein breakfast with eggs, they had lower levels of hunger and ate less at their next meal than those who ate an equal-calorie, low-protein, high-carb meal. With zero grams of cholesterol, egg whites are a great source of lean protein. Egg whites, on the other hand, have almost no fat and are almost entirely protein. Nearly all of the cholesterol and fat in an egg is stored in the yolk, along with other nutrients like vitamins and minerals. The FDA considers any food to be a good source of lean protein if it contains "less than 10 grams total fat, 4.5 grams or less saturated fat, and less than 95 milligrams cholesterol" per serving.īut that doesn't mean egg protein is out of the running for lean protein. You end up getting more protein for more than half the calories when you opt for egg whites over whole eggs. If you wanted to consume between 7 and 8 grams of protein, you could either eat 2 egg whites for 38 calories (8 grams of protein) or 1 whole egg for 80 calories (7 grams protein). If you're on a diet and you want to decrease your calorie intake, egg whites can be a good substitute for whole eggs. One extra-large egg white is 19 calories and one extra-large egg yolk is 61 calories. Because fat contains more calories per gram (9 calories/gram fat) than protein (4 calories/gram protein), egg whites are lower in calories than egg yolks.

The yolk is the home of nearly all of an egg's fat content. If egg yolks also contain protein, what is the benefit of only eating egg whites?Įven though yolks have nearly as much protein as egg whites, the reason egg whites earn most of the protein recognition is that they are lower in calories than yolks. Eating just 1 egg white would mean you're only consuming 4 grams of protein instead of the 7 grams of protein from a whole extra-large egg. In short: if you want to reap all the protein benefits of one egg, you'll need to consume the entire egg, both the yolk and white. In an extra-large egg with a total of 7 grams of protein, the protein content of the yolk and white will be split like this: Yolks also contain a significant amount of protein in an egg. Where is egg protein?Įgg whites tend to get all the credit when it comes to egg protein, but they're actually not the only source of protein in an egg. No matter how you cook an egg- poached, omelet, scrambled, fried, and hard-boiled-it will have about 6.3 grams of protein per large egg. In other words, each egg is just under 13 percent pure protein. Irrespective of the size, one egg contains 125 milligrams of protein per gram.
