Tackling malnutrition and sarcopenia in older persons with protein enriched beverages

Increased protein requirements are discussed in older persons in order to maintain muscle mass and muscle function until very old age. Simultaneously, protein intake of older persons is often reduced due to various reasons, e.g. dislike of meat, reduced appetite or chewing disorders. Currently, little is known about eating habits and nutritional protein sources of the elderly. It is assumed, that presently available protein drinks are not consumed, because they are difficult to find by older persons or do not meet their preferences.

In this subproject a protein-enriched drink will be developed and tested in older persons. The product will be adapted to specific preferences and metabolic needs of the elderly, will be available in the supermarket and thus contribute to adequate protein provision.

Objective:

The objective of the project is to develop a protein-rich, highly palatable drink in close cooperation with older persons, considering specific needs and preferences of this population group. The acceptance and the effects of the product on protein intake and eating habits will be investigated in an intervention study.
