A label line that reads “543 kJ per serve” only tells half the story. Divide by the serve size and you get the energy density, how much energy is packed into every 100 g of the food.
| Serving size | kJ per 100 g | kcal per 100 g | Energy density |
|---|---|---|---|
| 25 g serve | 2,172 kJ | 519 kcal | high |
| 40 g serve | 1,358 kJ | 324 kcal | medium |
| 60 g serve | 905 kJ | 216 kcal | medium |
| 100 g serve | 543 kJ | 130 kcal | low |
| 150 g serve | 362 kJ | 87 kcal | low |
| 250 g serve | 217 kJ | 52 kcal | very low |
For example, if a 60 g serve contains 543 kJ, the food has about 905 kJ per 100 g, a medium-density food, similar to bread, lean meat, eggs and pasta dishes. Scale any pack to your portion with the food label calculator.
