Many olive oil products use canonical nutritional values. The canonical values for energy (wikipedia) is 3700 kJ or 880 kcal. The products use 900 kcal instead. On US style nutritional tables, the canonical value is 120 Calories.

Many olive oil products use canonical nutritional values. The canonical values for energy (wikipedia) is 3700 kJ or 880 kcal. The products use 900 kcal instead. On US style nutritional tables, the canonical value is 120 Calories. Simple scaling implies than an Energy of 800 kcal.

The energy-kcal distribution shows this effect even more clearly:

The energy-kcal distribution shows this effect even more clearly: there are at least two peaks visible, due to the different origin of the data. The data is even more complex on closer inspection. We discuss that later in the section on normalisation.
