1,030 kJ On A Food Label
A label line that reads “1,030 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 | 2,575 kJ | 615 kcal | high |
| 60 g serve | 1,717 kJ | 410 kcal | high |
| 100 g serve | 1,030 kJ | 246 kcal | medium |
| 150 g serve | 687 kJ | 164 kcal | medium |
| 250 g serve | 412 kJ | 98 kcal | low |
Take a 60 g serve: 1,030 kJ ÷ 60 × 100 = 1,717 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.
