Which of the following statements regarding nutrition for older adults is true?

• A. Older adults may benefit from vitamin D supplements due to decreased bone density & a decreased ability to synthesize vitamin D from sunlight.
• B. Older adults may benefit from a vitamin B₁₂ supplement, because their ability to absorb vitamin B₁₂ from natural foods declines.
• C. As Calorie requirements decrease & older adults consume less, fiber requirements also decrease.
• D. All of the above.

Answer: (D)

Verified step by step guidance

1. Step 1: Understand the nutritional challenges faced by older adults, such as decreased bone density and reduced ability to synthesize vitamin D from sunlight, which can justify the need for vitamin D supplements.
2. Step 2: Recognize that the absorption of vitamin B\_12 from natural food sources declines with age due to changes in stomach acid production and intrinsic factor, making supplementation beneficial.
3. Step 3: Analyze the relationship between calorie intake and fiber requirements; although calorie needs decrease with age, fiber needs generally remain the same or may even increase to support digestive health.
4. Step 4: Evaluate each statement individually to determine its validity based on current nutritional science for older adults.
5. Step 5: Conclude that since all the statements accurately reflect nutritional considerations for older adults, the correct answer is that all of the above statements are true.
