585 kJ On A Food Label
A label line that reads “585 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 | 2,340 kJ | 559 kcal | high |
| 40 g serve | 1,463 kJ | 350 kcal | medium |
| 60 g serve | 975 kJ | 233 kcal | medium |
| 100 g serve | 585 kJ | 140 kcal | low |
| 150 g serve | 390 kJ | 93 kcal | low |
| 250 g serve | 234 kJ | 56 kcal | very low |
For example, if a 60 g serve contains 585 kJ, the food has about 975 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.
