Frequently Asked Questions
How many calories are in one egg?
One large egg contains approximately 72 calories. The white contributes about 17 calories and the yolk accounts for the remaining 55 calories.
How much protein is in one egg?
One large egg provides 6.3 grams of complete protein — roughly 3.6g in the white and 2.7g in the yolk. Cooked eggs have around 91% protein digestibility compared to 51% for raw eggs, so cooking significantly improves how much protein your body actually uses.
Do eggs raise cholesterol?
One egg contains 186mg of dietary cholesterol. However, a 2025 study in the American Journal of Clinical Nutrition found that saturated fat has a greater effect on raising LDL than dietary cholesterol from eggs. The 2025 Dietary Guidelines for Americans include no upper limit on dietary cholesterol from eggs.
Is it healthy to eat eggs every day?
For most healthy adults, one egg per day is considered safe and nutritious. A 2025 meta-analysis of 14 systematic reviews found no clear association between moderate egg consumption and all-cause mortality or most cardiovascular disease outcomes in the general population.
What vitamins are in eggs?
Eggs are an excellent source of choline (27% DV), selenium (28% DV), vitamin B12 (19% DV), riboflavin (18% DV), and vitamin A (9% DV). The yolk contains virtually all of the fat-soluble vitamins A, D, E, and K, as well as lutein and zeaxanthin for eye health.
