350 kJ On A Food Label
If 350 kJ is the per-serve figure on a nutrition panel, check the serving size next to it. Here is how the energy per 100 g changes with the size of that serve.
| Serving size | kJ per 100 g | kcal per 100 g | Energy density |
|---|---|---|---|
| 25 g serve | 1,400 kJ | 335 kcal | medium |
| 40 g serve | 875 kJ | 209 kcal | medium |
| 60 g serve | 583 kJ | 139 kcal | low |
| 100 g serve | 350 kJ | 84 kcal | low |
| 150 g serve | 233 kJ | 56 kcal | very low |
| 250 g serve | 140 kJ | 33 kcal | very low |
Take a 60 g serve: 350 kJ ÷ 60 × 100 = 583 kJ per 100 g, which puts it in the low-density group alongside fresh fruit, yoghurt, cooked rice and legumes. The food label calculator does this for any label.
