1,600 kJ On A Food Label
A label line that reads “1,600 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 |
|---|---|---|---|
| 60 g serve | 2,667 kJ | 637 kcal | high |
| 100 g serve | 1,600 kJ | 382 kcal | high |
| 150 g serve | 1,067 kJ | 255 kcal | medium |
| 250 g serve | 640 kJ | 153 kcal | medium |
For example, if a 60 g serve contains 1,600 kJ, the food has about 2,667 kJ per 100 g, a high-density food, similar to biscuits, chips, chocolate, nuts and oils. Scale any pack to your portion with the food label calculator.
