What is the nitrogen balance of a person who consumed a 3500-kcalorie diet containing 10 percent protein and excreted a total of 12 g of nitrogen?

Question

Quizplus · Accepted Answer

To calculate the nitrogen balance, first determine the nitrogen intake. A 3500-kcal diet with 10% protein means 350 kcal from protein (since 10% of 3500 kcal = 350 kcal). Since each gram of protein provides approximately 4 kcal, this translates to 87.5 grams of protein (350 kcal / 4 kcal/g). The general conversion factor for nitrogen content in protein is approximately 16%, so the nitrogen intake is 14 g (87.5 g * 0.16). With an excretion of 12 g of nitrogen, the balance is +2 g (14 g intake - 12 g excretion).
