Question

Quizplus · Accepted Answer

A study that compares the amount of a specific nutrient consumed with the amount of the nutrient excreted is called a balance study. This type of study is used to determine the nutrient requirements of an individual or a population. In a balance study, the amount of the nutrient consumed (usually over a period of several days) is compared to the amount of the nutrient excreted in urine and feces. If the amount consumed exceeds the amount excreted, it is assumed that the excess is retained by the body and used for various functions. If the amount consumed is less than the amount excreted, it is assumed that the body is using its stores of the nutrient to meet its needs. A balance study can provide valuable information about the metabolism of a nutrient and its requirements for health.
