All are true about Net protein utilization (NPU) except:: (A) Defined as Nitrogen retained / Nitrogen consumed X 100, (B) Good for estimating protein quality, (C) Egg has the highest NPU value, (D) 1 gram protein is equivalent to 1 gram Nitrogen
Answer is D. NPU Nitrogen retained by the body/ Nitrogen intake x100 NPU = / 100 It gives a more complete expression of Protein quality. Egg has the highest NPU value of 96 (100). 1 gram of Nitrogen is equivalent to : 6.25 grams of protein. NPU of Indian diet : 50-80.
