How Much Protein Is in 1 Egg? Full Guide to Egg Protein Content

How much protein is in 1 egg?

The quick answer

A typical chicken egg gives you roughly 6 g of protein, and USDA food-composition data list 6.28 g for one large raw egg. The same USDA table gives 6.26 g for one large fried egg and 6.25 g for one large poached egg.

The exact number depends on the egg size used by the source. In the Guy’s and St Thomas’ NHS guide, the values are rounded and tied to egg weight: medium eggs are listed at 8 g, large eggs at 9 g, and extra-large eggs at 10 g of protein. Those figures are approximate portion values, not a fixed rule for every egg.

Why the numbers are not identical

Food tables do not all use the same size conventions. That is why two official sources can both be useful and still show different numbers for “large” eggs.

Use the size category on the egg, not one universal number, when you want the best estimate.

Two eggs of the same size are roughly double one egg, so two large eggs will be about twice one large egg and two medium eggs will be about twice one medium egg. The safest way to count protein is to start with the egg size you actually have.

Approximate protein by egg size

How many grams are in the white and yolk?

What the official tables show

The retrieved official sources here give protein for whole eggs, not a separate white-versus-yolk split. The USDA legacy protein table lists one large raw egg at 6.28 g of protein, with very similar values for cooked forms: 6.26 g fried and 6.25 g poached. The NHS guide gives a size-based shortcut instead, listing 8 g for a medium egg (60 g), 9 g for a large egg (65 g), and 10 g for an extra-large egg (73 g).

That means the most reliable number depends on the exact egg you are counting. A shell egg, a carton of liquid egg, and a product made from only part of the egg are not the same thing, so whole-egg figures should not be copied across to every egg product. USDA’s FoodData Central is the USDA’s main food-composition system and includes analytical data, historical data, foundation foods, researchers’ data, and branded foods in one place.

Why whole-egg numbers are not enough for every product

The USDA protein table in the retrieved excerpt gives a value only for egg, whole. It does not provide a separate gram figure for egg white or egg yolk, and the NHS page in these results also reports only whole eggs by size. So if you are trying to total protein from an egg-white carton or from yolks used on their own, these exact source snippets do not give a verified per-part number.

For packaged egg products, the practical move is to check the exact product entry in FoodData Central or the product’s own nutrition information rather than assuming a whole-egg value applies. FoodData Central also includes label data collected through a public-private partnership, which is useful when the food is sold in a branded carton instead of as shell eggs.

Key takeaway: the verified numbers here are whole-egg numbers. If you are counting whites or yolks separately, use the exact product entry or label data rather than a whole-egg estimate.

Does cooking change egg protein?

The protein number changes very little

The USDA legacy protein table lists one large egg at 6.28 g protein raw, 6.26 g fried, and 6.25 g poached USDA Protein table. That is a spread of just 0.03 g across the three entries, so cooking does not materially change the protein amount listed for a large egg.

In the sources available here, the clean comparison is raw versus fried versus poached; there are no separate protein values shown for boiled, scrambled, or omelette-style eggs in the retrieved excerpt.

Cooking method matters more for safety than for protein grams

EFSA says that if Salmonella is present inside eggs, it can multiply more rapidly as storage time and temperature rise, and that thoroughly cooking eggs reduces the risk of infection EFSA on egg storage risks. EFSA’s Salmonella topic page also says Salmonella is commonly found in eggs and that thorough cooking, refrigeration, and good kitchen hygiene can prevent or reduce the risk posed by contaminated food EFSA Salmonella topic.

So the practical difference between raw and cooked eggs in the retrieved sources is not a bigger protein number. It is that cooked eggs are the safer choice.

For a large egg, the protein figure stays almost unchanged on paper; the bigger difference is safety, not grams.

Raw egg white is not a protein shortcut

The retrieved official sources do not provide human digestibility figures comparing raw and cooked egg protein, so they do not support any claim that raw egg white is a better protein strategy. What they do support is that uncooked or slightly cooked eggs carry more Salmonella risk than thoroughly cooked eggs EFSA on egg storage risks EFSA Salmonella topic.

When you compare egg data, check the basis of the number. The USDA table reports protein per egg, while the NHS guide gives approximate protein by egg weight: medium egg (60 g) 8 g, large egg (65 g) 9 g, and extra-large egg (73 g) 10 g NHS protein guide. Those are different ways of describing the food, so they should not be mixed without checking the serving basis first.

Is egg protein complete and high quality?

What protein quality means

In EFSA’s protein opinion, the adult Population Reference Intake is 0.83 g per kg body weight per day, which is a total-protein benchmark rather than a ranking of individual foods. EFSA Dietary Reference Values summary report EFSA sets population reference intakes for protein

How much protein do you need each day?

Start with the adult reference value

EFSA’s population reference intake for protein in healthy adults, including older adults, is 0.83 g per kilogram of body weight per day (EFSA protein PRI announcement). That is a daily target for a population, not a claim about eggs or any other single food.

To turn it into a personal figure, multiply body weight by 0.83. A 60 kg adult comes to about 49.8 g per day, 70 kg to 58.1 g, and 90 kg to 74.7 g. If you use the USDA legacy value for one large raw egg, 6.28 g protein, those targets equal roughly 8, 9, and 12 large eggs respectively (USDA Protein document).

Why egg counts are only rough estimates

The NHS guide for upper gastrointestinal surgery lists approximate protein values of 8 g for a medium egg, 9 g for a large egg, and 10 g for an extra-large egg (NHS protein guide). Because egg size changes the number, the same daily target can translate into different egg counts depending on which reference you use.

Higher intakes in athletic contexts

The NIH Office of Dietary Supplements notes that athletes may need considerably more protein, with recommendations reaching up to about 2 g per kilogram per day (NIH ODS exercise fact sheet). For a 70 kg athlete, that is about 140 g per day, which works out to roughly 22 large eggs using the USDA figure. That is a rough conversion, not a meal plan.

Eggs can help you move toward a protein target, but the target is for the whole day.

So the practical rule is simple: use the body-weight target first, then decide how many eggs fit alongside your other protein foods across the day. The common mistake is to treat a daily reference value like a protein claim for one food. EFSA’s number is a population intake target; the egg figures are food amounts.

How can eggs help you hit protein targets?

Use eggs as one protein component in a meal, then add another protein food beside them.

Build the plate around the egg, then add another protein food

One large egg is listed by USDA at 6.28 g protein raw, 6.26 g fried, and 6.25 g poached, so it is easy to use as a small, steady building block rather than the only protein on the plate.

Count the egg correctly

Use the same basis every time you log a meal. The USDA figures above show that the same large egg has slightly different protein values in raw, fried, and poached form, so switching between raw and cooked numbers can make your total look cleaner than it is. Count the whole egg you actually ate, and add any other ingredients in the dish separately instead of folding them into the egg number.

Spread protein across the day

Which egg forms should you buy for protein?

For a shell egg, USDA’s legacy protein table lists 6.28 g of protein for one large raw egg, with cooked values staying very close: 6.26 g fried and 6.25 g poached.

Compare the exact form you are buying

For cartons and dried products, use the protein figure for the exact item on the pack rather than assuming it matches a shell egg. The NHS guide from Guy’s and St Thomas’ says its tables show average portions and that you should check the product you buy because the numbers can change between brands and packs: Guy’s and St Thomas’ NHS protein guide.

Read the numbers, not the slogan

For any packaged egg product, the most useful figures are the protein amount and the serving size. If a pack also gives a per-100 g value, use that as a second comparison point so two products can be judged on the same basis.

Freshness and storage still matter for shell eggs

For shell eggs, EFSA says that extending storage time at home or at retail would increase Salmonella food-poisoning risks, and EFSA also notes that Salmonella is most frequently found in eggs: EFSA on egg storage and Salmonella risk, EFSA Salmonella topic. So the date on the pack and how the eggs have been handled are part of the buying decision as well.

Who should be cautious with eggs?

EFSA says Salmonella is commonly found in eggs and raw meat, and that eggs are the most important source of human infections in the EU. The clearest safety issue in the retrieved evidence is raw or lightly cooked eggs, because the estimated risk rises as storage time increases and as cooking becomes less thorough. EFSA Salmonella topic EFSA egg storage assessment

Raw and lightly cooked eggs are the main caution area

In EFSA’s 2014 assessment, extending the sell-by date from 21 to 28 days increased the estimated risk by 40% for uncooked eggs and 50% for slightly cooked eggs. In the worst-case scenario EFSA modelled, a 42-day sell-by date and a 70-day best-before date meant the risk was around three times higher than current conditions for both uncooked and slightly cooked eggs. EFSA also states that thoroughly cooking eggs reduces the risk of infection, while refrigeration is the only way to reduce the extra risk caused by longer storage. EFSA egg storage assessment

That means the safest reading of the evidence is simple: do not treat raw or only partially cooked eggs as a low-risk choice, especially if eggs have been stored for longer than usual. EFSA Salmonella topic

Thorough cooking and refrigeration are the two controls EFSA highlights most clearly for lowering egg-related Salmonella risk. EFSA egg storage assessment

Allergy, cholesterol, and other medical questions need individual advice

So if a clinician has already given you personal advice on food safety, dietary cholesterol, or a condition that changes how you should eat eggs, that advice should take priority over any general protein discussion. This section is about safety and risk, not about protein amount. EFSA Salmonella topic

For readers who want the shortest rule from this evidence set: keep eggs refrigerated, cook them thoroughly, and be especially careful with any egg dish that is meant to be runny, lightly set, or eaten after prolonged storage. EFSA egg storage assessment
