Things worth knowing

• One large hard-boiled egg (50 g) has about 78 kcal (324 kJ), 6.3 g of protein and 5.3 g of fat. A cup of chopped egg, about 136 g, comes to roughly 211 kcal (882 kJ).
• Boiling adds no calories. Frying does: a fried whole egg has about 196 kcal per 100 g in USDA data, compared with 155 kcal for hard-boiled, because of the fat absorbed from the pan.
• Most of the fat, cholesterol and vitamins sit in the yolk. Raw yolk alone has about 322 kcal per 100 g, while the white is mostly water and protein.
• Per large egg you get roughly 147 mg of choline, about a quarter of the 550 mg Daily Value, plus about 15 µg of selenium (28% DV) and 0.56 µg of vitamin B12 (23% DV).
