I keep being amazed at how most sources keep using the calorie as unit, even though it has been phased out a couple of decades ago. The international standard unit is the Joule. I'm even more amazed at how this can be the case in countries that do not normally degrees Celcius/Kelvin and grams as basic units (which is how the calorie is defined: the amount of heat (energy) needed to raise the temperature of 1 gram of water by 1 degree Celcius (or 1 Kelvin)). Even the more-or-less official dutch nutrition centre (http://www.voedingscentrum.nl/) keeps using calories as the first unit, and Joules only as second (in many places).
