Definition of Calorie
Calorie: A unit of food energy. In nutrition terms, the word calorie
is used instead of the more precise scientific term kilocalorie which represents
the amount of energy required to raise the temperature of a liter of water one
degree centigrade at sea level. The common usage of the word calorie of food
energy is understood to refer to a kilocalorie and actually represents,
therefore, 1000 true calories of energy. A calorie is also known as cal, gram
calorie, or small calorie.
