Answer: 71–72

Flashcard 3: _____ deficiency (mineral) is associated with hypo-gonadism

Answer: Zinc

Flashcard 4: Which score is currently considered the best indicator of protein quality, and what is the site of digestibility measurement used for its calculation?

Answer: Digestible Indispensable Amino Acid Score (DIAAS); Ileal digestibility

Flashcard 5: _____ deficiency presents with hypocholesterolemia and weight loss

Answer: Manganese

Flashcard 6: Starter F75 has 75 kcal and _____ g protein per 100 mL

Answer: 0.9

Flashcard 7: Keshan's disease is due to deficiency of which element?_____

Answer: Selenium

Flashcard 8: 1. Identify → _____ 2. Nutritional values → 43.2% protein, Deficient in methionine and cysteine, NPU 55, 432 kcal/100gm

Answer: Soyabean

Extra: Soybeans are a rich source of plant-based protein and are widely used in clinical nutrition and public health programs. While they are deficient in sulfur-containing amino acids (methionine and cysteine), they are rich in lysine, making them an excellent complement to cereal proteins.

Flashcard 9: _____ is an "internal" indicator of protein quality

Answer: Biological value (BV)

Extra: NPU (Net Protein Utilization) is an "external" indicator because it measures nitrogen retained relative to nitrogen **intake**. NPU = BV × Digestibility coefficient

Flashcard 10: _____ has the maximum NPU(net protein utilisation)

Answer: egg

Extra:
