For a while there, the humble egg white was the undisputed king of the health world. If you were serious about fitness, you ordered the egg-white omelette. It became a symbol of lean, clean eating. And the numbers make sense: it's almost pure protein, with barely a calorie from anything else. But in ditching the yolk, you're also ditching a whole host of vitamins and healthy fats. So, is the egg white really the healthier choice? The answer is... it's a tool. A brilliant one for some goals, but not the whole story.
↑ An egg white is about 90% water and 10% protein.
The lean protein story
An egg white, or albumen, is a fascinating substance. It's about 90% water, with the other 10% being almost entirely protein. It's designed to protect the yolk and provide nutrition for a growing chick, which is why it's packed with high-quality, easily absorbed proteins.
For humans, this translates to a food that's a lean, mean, protein-delivering machine. It offers the muscle-building and satiety benefits of protein with almost none of the fat, carbs, or cholesterol that come along with other protein sources. This is why it became the darling of the 80s and 90s low-fat craze. The story isn't that simple, of course, but it's a useful starting point.
IN ONE LINE
Egg white is a fantastic tool for boosting protein intake while keeping calories and fat extremely low. The trade-off is that you miss out on the vitamins, minerals, and choline found in the yolk.
Egg white nutrition facts
Here's what 100 grams of raw liquid egg white — the equivalent of about three large egg whites — provides, according to the USDA.
The numbers are stark. For 52 calories, you get nearly 11 grams of complete protein. That's an incredibly efficient protein-to-calorie ratio, beaten by very few other foods. The carbohydrate and fat content are so low they're nutritionally insignificant.
Are egg whites better than whole eggs?
This is the big question. And the answer is no, not for most people. Think of them as different foods for different jobs. The yolk contains nearly all of an egg's vitamins A, D, E, K, its choline (crucial for brain health), and healthy fats. For decades we were told to fear the yolk's cholesterol, but modern science has largely shown that dietary cholesterol has little impact on blood cholesterol for most of us.
A whole egg is a more complete nutritional package. An egg white is a specialist. It's 'better' only if your specific goal is to maximize protein while minimizing calories, fat, and cholesterol. For an athlete, a bodybuilder, or someone on a strict low-fat diet, they are a fantastic tool. For everyone else, the whole egg is probably the smarter, more satisfying choice.
Cartoned liquid egg whites are pasteurized, meaning they are safe to add to smoothies or other uncooked recipes, unlike raw whites from a cracked egg which carry a risk of salmonella.
Egg white's glycemic index
Glycemic index (GI) measures how quickly a food's carbohydrates raise your blood sugar. Since egg whites contain less than one gram of carbohydrate per 100g serving, they have a glycemic index of effectively zero. They simply don't have enough sugar or starch to cause any response. This makes them an ideal food for blood sugar management, as they provide fullness and protein without affecting glucose levels at all.

How to use egg whites
Egg whites are more of an ingredient than a standalone food. Here are a few ways to incorporate them.
01
Make a lean omelette.
This is the classic. Use 3-4 egg whites instead of 2 whole eggs for a bigger, higher-protein, lower-calorie meal. Just be sure to add lots of veggies and herbs for flavor.
02
Whip them for volume.
Whipped egg whites are the foundation of meringues, soufflés, and cloud bread. They create a light, airy structure with very few calories.
03
Boost your smoothie.
A quarter-cup of pasteurized liquid egg white adds over 6g of pure protein to a smoothie with no taste and a silky texture.
04
Lighten up baked goods.
You can use egg whites to bind and leaven things like protein pancakes or healthy muffins, reducing the fat content from whole eggs.
05
Don't be afraid to mix.
A great compromise is an omelette made with one whole egg and two extra egg whites. You get the nutrients of the yolk plus the lean protein volume of the whites.

An egg white on its own is, let's be honest, pretty bland. Its magic lies in being a neutral canvas for other flavors and nutrients.

FREQUENTLY ASKED QUESTIONS
Frequently asked questions
Are liquid egg whites from a carton healthy?
Yes, they are just as healthy as fresh egg whites. They are pasteurized, which makes them safer for use in uncooked preparations like smoothies. Always check the label to ensure there are no unwanted additives like salt or gums.
How much protein is in one egg white?
A single large egg white contains about 3.6 grams of protein. Our nutrition panel is for 100g, which is roughly three large egg whites and contains about 10.9 grams of protein.
Are egg whites better than a whole egg for weight loss?
They can be a useful tool. Because they are lower in calories (about 17 calories per large white vs. 72 for a whole egg), you can eat a larger volume for the same calorie cost, which can help with fullness. However, the fat in the yolk also contributes to satiety, so some people find whole eggs keep them full longer.
Do egg whites cause bloating?
For most people, no. They are very easy to digest. However, egg is one of the most common food allergens. If you have an egg allergy or intolerance, they can certainly cause digestive issues, including bloating, gas, or cramps.
