Protein Intake for Older Adults
On this page
Older adults may need more attention to protein quantity, distribution, appetite, dental or swallowing problems, illness, and resistance exercise. A generic number cannot replace clinical assessment.
Use the Protein Calculator only as a starting arithmetic tool for a generally healthy adult.
Evidence context
The PROT-AGE expert group proposed at least 1.0–1.2 g/kg/day for many healthy older adults, with higher amounts in some illness or activity contexts. This is expert guidance, not a universal prescription. Current US Dietary Guidelines also present a broader 1.2–1.6 g/kg/day target.
For 70 kg, 1.0–1.2 g/kg is 70–84 g/day. Food intake, kidney function, illness, wounds, and clinician goals can change the plan.
Distribution and meals
Spreading protein across meals can help when breakfast is habitually low. Use the Protein per Meal Guide as a practical planning tool, not a rigid threshold.
Protein and resistance exercise
Protein and appropriately supervised resistance exercise work together to support muscle function. Nutrition alone does not replace strength, balance, mobility, and medical evaluation.
Kidney disease and other exceptions
The National Kidney Foundation explains that protein needs in chronic kidney disease vary by stage, dialysis status, and nutrition needs. Do not apply a high-protein target to CKD without the care team. Swallowing difficulty, unexplained weight loss, poor appetite, or functional decline also deserves professional assessment.
