Things worth knowing
- One standard bun (44 g) has about 123 kcal (514 kJ) and about 217 mg of sodium. Bakery buns are often bigger: an 80 g bun at the same density has about 223 kcal.
- Whole-wheat buns are similar in energy at about 269 kcal per 100 g, but have about 6.1 g of fibre against 1.8 g in a plain white bun.
- Brioche buns are richer: USDA's figure for brioche is about 427 kcal per 100 g, roughly 50% more than a plain bun, because the dough contains butter and egg.
- Toasting the bun crisps the surface by driving off water but does not reduce its calories, and buttering it before toasting adds about 34 kcal per teaspoon.
