A label line that reads “2,500 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 |
|---|---|---|---|
| 100 g serve | 2,500 kJ | 598 kcal | high |
| 150 g serve | 1,667 kJ | 398 kcal | high |
| 250 g serve | 1,000 kJ | 239 kcal | medium |
Take a 100 g serve: 2,500 kJ ÷ 100 × 100 = 2,500 kJ per 100 g, which puts it in the high-density group alongside biscuits, chips, chocolate, nuts and oils. Scale any pack to your portion with the food label calculator.
