The calorie is a unit of energy, first defined by Professor Nicolas Clément in 1824 as a unit of heat. In most fields its use is archaic, having been replaced by the SI unit of energy, the joule. However, in many countries it remains in common use as a unit of food energy.
Some countries use the food calorie, which is equal to 1 kilocalorie (kcal), or 1,000 calories. In the context of nutrition, and especially food labeling, the calories are large calories approximately equal to 4.1868 kilojoules (kJ). The kilojoule is the unit officially recommended by the World Health Organization and other international organizations.
No matter how you count them, they are important. This week, a look at calories.
TTFN, Fred.
