Learning objectives

  • Explain higher protein needs in older adults
  • Identify hydration risks
  • Describe nutrients important for bone and muscle
  • Know when to refer to a dietitian

Before this lesson

Why this matters

Muscle maintenance needs both training and adequate nutrition, and older adults often under-eat protein.

Protein [bauer2013]

SituationDaily protein
Healthy older adults1.0–1.2 g/kg
Active / acute or chronic disease1.2–1.5 g/kg
Severe kidney diseaseMedical advice (may be lower)

Spread across meals (~25–30 g each). Indian options: dal, paneer, curd, eggs, chicken, fish, soy, chana.

Other nutrients

Vitamin D and calcium (bone), energy adequacy (prevent unintended weight loss), fibre.

Hydration

Encourage regular drinking, especially in heat and with diuretics.

Nutrition plus resistance training is the foundation of sarcopenia management [cruzjentoft2019].

Common mistakes and misconceptions

Case study

A 75-year-old eats ~45 g protein per day. With dietitian support she adds curd at breakfast, dal and paneer at lunch and an egg snack, reaching ~80 g/day; her strength gains accelerate.

Key takeaways

  • Older adults need more protein: about 1.0–1.2 g/kg/day, and 1.2–1.5 g/kg/day with illness or exercise.
  • Distribute protein across meals (around 25–30 g per meal).
  • Thirst declines with age — encourage regular fluid intake.
  • Refer for unintentional weight loss, poor appetite or complex medical diets.
