How to calculate calories in Bread
Multiply the calories per 100 g by your portion weight, then divide by 100. For the reference 30 g portion, the calculation is:
265 × 30 ÷ 100 ≈ 80 kcal
Reference portion: slice (30 g). This is an example amount, not a recommended portion. Weigh your food when possible: a cup, slice or piece can vary in size.
Check that the entry matches the food you have, including its preparation. If raw or cooked is not specified, check your label or a matching nutrition reference before logging it.
