METABOLIC AVAILABILITY OF ENERGY OF INGESTED ETHYL ALCOHOL

Abstract
Over 50 years ago Atwater and Benedict reported that the energy available from alcohol in metabolism in the same as that obtained in the bomb calorimeter. Mitchell suggested in 1935 that only about 75% is available for physiological purposes. The rate of growth of young rats is proportional to calorie intake (until this becomes optimal) when all other essential dietary factors are supplied in adequate amount. By taking advantage of this fact we have re-established that all the energy of ethanol found by bomb calorimetry is available in metabolism.
