The Role of Protein in Malnourished Older Adults

Malnutrition in older adults is often linked with frailty and may develop when a person's nutritional intake does not provide them the right amount of energy (calories), protein and other nutrients. Clinical evidence and guidelines support higher protein intake in this cohort¹ .

Why is protein important?

When protein intake is insufficient, the body breaks down muscle tissue³ , increasing the risk of frailty. The primary protein reservoir is skeletal muscle⁴ , unlike carbohydrates and fats which have non-tissue storage forms.

Older adults tend to consume less protein than younger individuals¹ . This issue is compounded by age-related metabolic changes⁵ , and the need to counteract the elevated metabolism from inflammatory diseases¹.

Evidence supports higher protein intake in older adults for health, recovery from illness and to maintain function³.
