Nitrogen balance is the
traditional method of determining dietary protein requirements. Determining

growth, hypothyroidism, tissue repair, and pregnancy. This means that the
intake of nitrogen into the body is greater than the loss of nitrogen from the
body, so there is an increase in the total body pool of protein.
