Which statement most closely defines a Calorie?

Question

Quizplus · Accepted Answer

A Calorie (with a capital C) is a unit of measurement used to express the energy content of food or the amount of energy expended in physical activity. It is a measure of the energy potential of food. One Calorie is equivalent to 1,000 calories (with a small c), which is the amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius.

Note: None of the other options really define what a Calorie is. A is close, but nutrient density is a separate concept from energy content. B is too broad--Calories are specific to food and physical activity. D and E are incorrect.
