Answer:
Taylor’s nitrogen balance is -2.72g
Explanation:
Given the data in the question;
In Taylor's "new" lower-kilocalorie diet, she consumes 63 g of protein
UUN loss was 9 g
Taylor’s nitrogen balance = ?
first we determine nitrogen content in the diet;
Nitrogen = gram of protein / 6.25
where 6.25 is a conversion factor
so
Nitrogen = 64 / 6.25
Nitrogen = 10.08 g
Next we determine Nitrogen loss;
Nitrogen loss = UNN(grams) + ( 0.2 × UNN grams) + 2 grams
Nitrogen loss = 9 g + ( 0.2 × 9 ) + 2g
Nitrogen loss = 9 g + 1.8 + 2 g
Nitrogen loss = 12.8 g
So, the nitrogen balance will be;
Nitrogen Balance = nitrogen content in the diet - Nitrogen loss
Nitrogen Balance = 10.08 - 12.8
Nitrogen Balance = -2.72g
Therefore, Taylor’s nitrogen balance is -2.72g
