Passage-E
What do we mean when we speak of a calorie? Well, we know
that the food we eat is burned and provides heat. Some foods can provide much
heat and other foods very little. The foods that provide much heat provide many
calories. We measure the amount of heat a food provides in calories, just as we
measure your height in inches or your weight in pounds. A calorie is a measure
of the heat required to raise the temperature of one gram of water one degree
centigrade. One calorie of food can also raise one pound of matter to a height
of 40 inches. Two thousand calories a day of food in the body can provide a lot
of heat and the ability to do a lot of work.
