What is the recommended daily protein intake per kilogram of body weight for healthy older adults?

• A. 0.8 g/kg/day
• B. 1.0 g/kg/day
• C. 1.2 g/kg/day
• D. 1.5 g/kg/day

Answer: (A)

The amount of protein that meets the needs of most healthy people is 0.8 g per kilogram of body weight each day. This baseline, the Recommended Dietary Allowance, is intended to support normal body functions and prevent deficiency, including in older adults. While some experts suggest higher intakes (around 1.0–1.2 g/kg/day) for older adults to help preserve lean mass, for healthy older adults the standard 0.8 g/kg/day is considered the appropriate target. To apply it, multiply your weight in kilograms by 0.8; for example, a 70 kg person would aim for about 56 g of protein per day. Spreading protein intake across meals can help maximize muscle protein synthesis, using a mix of high-quality sources rich in leucine.
