Protein requirements of man: comparative nitrogen balance response within the submaintenance-to-maintenance range of intakes of wheat and beef proteins


Protein requirements of man: comparative nitrogen balance response within the submaintenance-to-maintenance range of intakes of wheat and beef proteins

Groups of 6 to 8 men aged 18 to 24 years were given either whole wheat or beef as protein source in diets with protein-free energy sources, minerals and vitamins, for four 15-day balance periods. Daily intake of protein differed between periods, ranging from 0.3 to 0.65 g/kg bodyweight from wheat or 0.2 to 0.5 g/kg from beef. A table shows N excretion in faeces and urine, balance, net protein utilisation and mean digestibility for each source and trial.
