Protein undernutrition is a major health concern for older adults, especially for those who are ill. The target of 1.2-1.5 gram protein/kg bodyweight/day is not reached by the majority of older adults. Therefore, more effective and novel strategies to increase protein intake are warranted, including the use of protein-enriched foods and drinks. This thesis evaluated the impact of developed protein-enriched foods and drinks on protein intake and physical performance among older adults. The studies were done as part of the Cater with Care-project; a collaboration between the university, care organizations, and partners from the food industry.
It was concluded that with the protein-enriched familiar foods and drinks, we have a feasible, acceptable, and appetizing long-term strategy to increase protein intake of older adults in various settings. We envisage a beneficial role of these protein-enriched products in combination with physical activity in older adults with lower protein intakes.
