A short-term N balance study was conducted in twelve healthy female adults aged 21-32 years to determine their protein requirement.
Four dietary protein levels (0.3, 0.4, 0.5 and 0.6 g protein/kg per d) were used.
Energy intake of the subjects was kept constant at 0.18 MJ/kg per d. All subjects maintained their normal activity throughout the study period.
N excretion was determined from the measurements of N in a total coUection of urine, faeces, sweat and menstrual fluid for each dietary period.
N balance during the four protein levels were -1515 (SD 5.95), -5.53 (SD 6.71), +6.15 (SD 4.76) and +12.05 (SD 8.63) mg N/kg per d for 0.3, 0.4, 0.5 and 0.6 g protein/kg per d respectively.
