For years, the egg was public enemy number one at the breakfast table, blamed for everything from high cholesterol to heart disease. That advice, we now know, was mostly wrong. An egg is a self-contained, perfectly portioned package of high-quality protein and healthy fats with virtually zero carbohydrates. It's one of the most nutrient-dense, versatile, and affordable foods you can eat. The trick isn't avoiding eggs; it's embracing them, yolk and all.
↑ An egg is a near-perfect food: protein, fat, and essential nutrients, all for about 72 calories.
Breakfast's comeback kid
Let's be honest, the egg has had a rough couple of decades. Once a breakfast staple, it was sidelined by fears over dietary cholesterol. We were told to eat the whites, skip the yolks, or avoid them altogether.
Thankfully, that story has changed. We now understand that for most of us, the cholesterol we eat has a surprisingly small effect on the cholesterol in our blood. The real story of the egg is its incredible nutrient density. It's a high-protein, low-calorie, zero-sugar food that keeps you full and delivers essential nutrients in one neat, 72-calorie package.
IN ONE LINE
A whole egg is a zero-GI, high-protein food. The outdated fear of its cholesterol has been largely debunked; it's one of the best foods you can put on your plate.
Large egg nutrition facts
The numbers below are for 100 grams of whole large egg, which is about two eggs. A single large egg is roughly half these values.
But what about the cholesterol?
This is the big one. For decades, we linked the cholesterol in eggs directly to the cholesterol in our blood. It seems logical, but it's not how our bodies work. For about 70% of the population, eating cholesterol has a minimal impact on blood cholesterol levels. Your liver produces most of the cholesterol in your body, and it simply produces less when you eat more. The bigger dietary culprits for raising 'bad' LDL cholesterol are saturated and trans fats, not dietary cholesterol itself.
Don't skip the yolk! It's where you'll find most of the nutrients, including fat-soluble vitamins and the crucial nutrient choline, which is vital for brain health.
An egg's glycemic index is zero
Glycemic index (GI) measures how quickly a food's carbohydrates raise your blood sugar. Since eggs contain virtually no carbohydrates, they have a glycemic index of 0. This means they have no impact on blood sugar levels, making them an exceptional food for anyone managing diabetes, following a low-carb or keto diet, or simply trying to avoid energy spikes and crashes.

The best way to eat eggs
You can't really go wrong, but a few simple habits will help you get the most out of your eggs.
01
Eat the whole thing.
The yolk is a nutritional goldmine. Egg white omelets are a relic of the low-fat craze; you're throwing away the best part.
02
Choose gentle cooking methods.
Poaching, boiling, and scrambling over gentle heat are fantastic. Frying in lots of butter or oil adds significant calories and saturated fat.
03
Pair them with fiber.
Eggs have no fiber, so pair them with vegetables (like in an omelet), avocado, or a slice of whole-grain toast for a truly complete meal.
04
Don't overdo the salt.
Eggs are naturally low in sodium. A pinch of salt is fine, but it's easy to go overboard. Try black pepper, chili flakes, or fresh herbs instead.
What eggs are good for
01
High-Quality Complete Protein
With over 12 grams per 100g serving, eggs provide all nine essential amino acids, making them a 'complete' protein for muscle repair, immune function, and satiety.

FREQUENTLY ASKED QUESTIONS
Frequently asked questions
Is the cholesterol in eggs bad for my heart?
For most people, no. Decades of research have shown that dietary cholesterol (from food) has a very small impact on blood cholesterol. Saturated and trans fats are much bigger concerns. Most major health organizations no longer set a specific limit on dietary cholesterol for the general population.
How many eggs can I eat a day?
For a healthy person, eating 1-2 eggs per day is perfectly safe and beneficial. Some studies show that even more is fine. It's more important to consider your overall diet; two eggs with spinach and avocado is very different from two eggs with bacon, white toast, and butter.
Are brown eggs more nutritious than white eggs?
No, this is a common myth. The color of the eggshell is determined by the breed of the hen and has no bearing on the egg's nutritional content or taste. Choose whichever you prefer or whichever is more affordable.
Should I only eat the egg whites?
Definitely not, unless you've been specifically advised to for medical reasons. The yolk contains the vast majority of the nutrients, including healthy fats, vitamins A, D, E, and K, and important compounds like choline. The white is mostly just protein.
