Food eaten and digested in the body are converted
into calories. Food when broken down inside the body turns into usable sugar,
called glucose. Glucose is a key component in determining caloric values in
food. When you digest food, the nutrients that they provide are calculated in
the form of calories. This is what you usually see in the food labels that are
printed outside of wrappers in food you buy from the supermarkets.
On average a person should consume between 1,500-2,000 calories per day in
order to maintain proper bodily functions. Excessive amounts of caloric intake
and less exercise may lead to obesity and other health related diseases.
