1,300 kJ On A Food Label
A label line that reads “1,300 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 |
|---|---|---|---|
| 40 g serve | 3,250 kJ | 777 kcal | high |
| 60 g serve | 2,167 kJ | 518 kcal | high |
| 100 g serve | 1,300 kJ | 311 kcal | medium |
| 150 g serve | 867 kJ | 207 kcal | medium |
| 250 g serve | 520 kJ | 124 kcal | low |
Take a 60 g serve: 1,300 kJ ÷ 60 × 100 = 2,167 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.
