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 .

High Protein 85 percent study

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.

ESPEN guidelines highlight the increased protein requirement for malnourished older adults1

HIGH-PROTEIN-WEBPAGE-ESPEN

85% of older adults do not meet the ESPEN recommended protein intake of 1.2g/kg/day2.

High proteinᶱ ONS improve patients' outcomes and quality of life6

High protein intakes are associated with improved clinical and ecomonic outcomes6. High proteinᶱ ONS increases nutritional intake without suppressing individuals' appetite or voluntary food intake#.

In a meta-analysis with mean energy density (1.5kcal/ml), high protein ONS significantly reduce complications7. These included: infections, falls and post-operative complications.
