The numbers, taken straight from USDA FoodData Central — not scraped from another recipe site. Calories and protein change with egg size, so every figure here is stated per size, not per “one egg.”
The numbers
- Calories 78 calories in a large hard-boiled egg — and how that shifts from small to jumbo.
- Protein 6.3 g per large egg — and the reference protein against which others are scored.
- Full nutrition facts The complete macro and micronutrient table: fats, choline, B12, selenium, vitamin D.
- Health benefits and risks What the research actually says — including the cholesterol question, answered honestly.
The honest summary
A boiled egg is one of the most nutrient-dense foods per calorie you can eat: complete protein, choline, B12, selenium, and vitamin D in about 78 calories, with nothing added by the cooking method — boiling adds no fat, which is why boiled eggs anchor so many eating plans. The cholesterol story has moved: dietary cholesterol raises blood cholesterol far less than once assumed, and current guidance for most healthy people accommodates an egg or more a day — though individuals differ, and anyone managing a heart condition should ask their own clinician rather than a website. Every page in this section shows exactly where its numbers come from, and says plainly what it hasn’t had checked.
