Abstract:

The variability of daily stool energy losses was examined in six healthy adult women over a complete menstrual cycle On average, stool energy was 0.74 ± 0.15 kK/d (m̄ ± SD) for the group. For a given individual, daily stool energy varied up to twofold. The variability for rolling averages of daily fecal energy losses over 3-, 5-, and 7-d periods showed no significant differences between collection periods of 3 and 5 d and 5 and 7 d. There was a close linear relationship between the energy content of the stool and either the wet or dry weight of stool (range 17-460 g wet wt). In metabolic studies of healthy women representative values for daily losses of energy in stool can be obtained from a 3-d collection. The energy content of wet stool was ≈ 7 kJ/g. Under field conditions, weighing the stool provides a simple, useful method of assessing fecal energy losses.

Abstract:

The variability of daily stool energy losses was examined in six healthy adult women over a complete menstrual cycle. On average, stool energy was 0.74 +/- 0.15 kJ/d (mean +/- SD) for the group. For a given individual, daily stool energy varied up to twofold. The variability for rolling averages of daily fecal energy losses over 3-, 5-, and 7-d periods showed no significant differences between collection periods of 3 and 5 d and 5 and 7 d. There was a close linear relationship between the energy content of the stool and either the wet or dry weight of stool (range 17-460 g wet wt). In metabolic studies of healthy women representative values for daily losses of energy in stool can be obtained from a 3-d collection. The energy content of wet stool was approximately 7 kJ/g. Under field conditions, weighing the stool provides a simple, useful method of assessing fecal energy losses.
