Question 47

• Rickets is a childhood disease caused by vitamin D deficiency, affecting bone development (not loss of bone mass/density).
• Osteoporosis is defined by reduced bone mass and density, increasing fracture risk.
• Calcification is the deposition of calcium (not bone mass loss).
• Decalcification is the removal of calcium (a process, not a disease with bone mass loss as a primary feature).

Dietary surveys and research show that most Americans consume more protein (especially from animal sources) than the recommended dietary allowance (RDA) for protein.
