1,090 kJ On A Food Label
A label line that reads “1,090 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 | 2,725 kJ | 651 kcal | high |
| 60 g serve | 1,817 kJ | 434 kcal | high |
| 100 g serve | 1,090 kJ | 261 kcal | medium |
| 150 g serve | 727 kJ | 174 kcal | medium |
| 250 g serve | 436 kJ | 104 kcal | low |
Take a 60 g serve: 1,090 kJ ÷ 60 × 100 = 1,817 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.
