Which statement describes an association between energy measurement and foods? ​

Quizplus · Accepted Answer

Bomb calorimetry measures the total energy released during complete combustion of a food, including the energy from indigestible components. However, the human body is not able to extract all of the energy from a food, so the physiological fuel value is lower than the energy value as determined by a bomb calorimeter. Indirect calorimetry can be used to measure energy expenditure during metabolism of different macronutrients, but it cannot be used to determine the energy value of alcohol. Direct and indirect calorimetry may give similar values for some foods, but not always.
