Although proteins differ in nitrogen content because of differences in their amino acid compositions, the N content of protein in a typical Western diet averages 16% (w/w). Using this average value, calculate your daily dietary protein requirement to maintain nitrogen balance assuming you excrete 120 mg of N/kg body weight each day.
