Which statement accurately reflects recommended protein intake for older adults?

• A. 3.0-4.0 g/kg/day
• B. 2.0-3.0 g/kg/day
• C. 0.8-1.5 g/kg/day
• D. 0.2-0.4 g/kg/day

Answer: (C)

Older adults need enough protein to preserve muscle, support recovery, and maintain immune function, especially because muscle protein synthesis can be less responsive with age. The range from about 0.8 g/kg/day up to 1.5 g/kg/day reflects both the general minimum to prevent deficiency and the higher amounts often recommended for older individuals who are frail, ill, recovering from surgery, or under chronic disease stress. So, aiming within this span covers the typical needs and the increased needs seen in many older adults. For example, a 70 kg person would target roughly 56–105 g of protein daily, distributed across meals with good-quality sources. If kidney function is a concern, adjust under clinician guidance; otherwise this range is a practical guideline for older adults.
