Rationale: Due to inactivity, elderly are prone to lose muscle mass. With an increased protein intake, muscle mass might be maintained. The current recommendation for protein intake for elderly is the same as for younger adults, but researchers and geriatricians appeal for a higher recommended protein intake to maintain health and function. One way to reach a higher intake is by providing protein-enriched foods. Because of concerns that these foods are more satiating, careful monitoring of protein intake after introducing these foods is warranted.
