900 kJ On A Food Label
A label line that reads “900 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 |
|---|---|---|---|
| 25 g serve | 3,600 kJ | 860 kcal | high |
| 40 g serve | 2,250 kJ | 538 kcal | high |
| 60 g serve | 1,500 kJ | 359 kcal | medium |
| 100 g serve | 900 kJ | 215 kcal | medium |
| 150 g serve | 600 kJ | 143 kcal | medium |
| 250 g serve | 360 kJ | 86 kcal | low |
For example, if a 60 g serve contains 900 kJ, the food has about 1,500 kJ per 100 g, a medium-density food, similar to bread, lean meat, eggs and pasta dishes. Scale any pack to your portion with the food label calculator.
