Things worth knowing
- Wholemeal bread is nearly identical in calories, about 254 kcal per 100 g, but carries roughly three times the fibre and considerably more magnesium and zinc.
- Bread is a major source of sodium in many diets: 100 g supplies around 490 mg, about 21 percent of the daily reference intake.
- Toasting does not add calories. It drives off water, so a toasted slice is lighter but contains the same energy.
- In the United States and United Kingdom, white flour is fortified, which is why enriched white bread shows high iron and B-vitamin values despite the bran and germ being removed.
Converting these figures
One 1 slice (standard) of white bread is 66 kcal, which is 278 kJ. To convert any other figure, divide kilojoules by 4.184 for calories, or use the converter on the home page.
It takes 90 g of white bread to reach 1,000 kJ (239 kcal). See how that compares with other foods on the 1000 kJ to calories page.
