Every activity our bodies perform

requires energy. The energy our

bodies require to carry out the

activities in our daily lives comes

from food and drinks, which provide

us with nutrients. The nutrients our

bodies receive energy from are proteins,

1 and fats. Each of these nutrients contains different amounts of

energy which can be measured in2 . Each type of nutrient contains a

different amount of calories per gram (cal./g), with fats containing the most (9 cal./g) and proteins

and carbohydrates providing the same amount (4 cal./g). When we eat, we provide our bodies with

an amount of energy known as* . Knowing the amount of calories we

are introducing into our bodies is important because consuming too many calories or too few calories

means that we will not achieve energy4 . In order to help us keep track

of food or drink that has the number of calories listed on the label.
