Food fortification is used as a nutrition support strategy in aged care homes, for residents who are malnourished or at risk of malnutrition. The aim of this review was to determine the scope and strength of published works exploring relationships between food fortification strategies, mode of delivery and sustainability in aged care homes. Literature from four databases and grey literature was searched. A total of 3152 articles were screened. Seventeen studies were included. Results showed that the majority of studies used pre-made food fortification, rather than fortifying foods on-site. There was heterogeneity across studies, including the mode of delivery and ingredients used for food fortification. Only two studies measured any aspect of costs. No clear sustainable strategies for implementing food fortification in this setting could be identified. Research is required to provide further insight into the acceptability and sustainability of food fortification interventions. ARTICLE HISTORY

The role of foodservices in aged care is difficult to understand, and strategies to improve the nutritional care of residents are often unsustainable. In particular, food-first strategies such as food fortification are poorly executed in everyday practice and its execution relies upon the foodservice system in aged care homes. The aim of this study was to explore the perspective of staff on the role of foodservices in aged care and gauge the level of skills, education, access, time, and ability to deliver food fortification. Semi-structured interviews were conducted with foodservice managers, foodservice workers, dietitians, carers, and other managers who work in aged care homes across Australia. Participants were recruited purposively through email and through snowballing. Interviews (n = 21) were recorded, transcribed verbatim, and analyzed using inductive thematic analysis. Three themes and six sub-themes were identified. The three themes include the role of foodservices being more than just serving food, teamwork between all staff to champion nutrition, and workplace culture that values continuous improvement. These themes identify how staff perceive the role of foodservices in aged care and provide an important perspective on the long-term sustainability of food fortification strategies and how to improve current practice.

Background There is a clear need for food and nutrition research to lead to pragmatic and sustainable solutions to the ongoing problems in residential aged care, particularly within foodservices. The present study aimed to identify systemic challenges for residential aged care homes in Australia to participate in quality food and nutrition research, using a complexity science lens. Methods Qualitative data from three studies in residential aged care were gathered, which included 28 participants across 21 aged care homes. Qualitative data consisted of in‐depth interviews, field notes and email communications with aged care staff. Thematic analysis was undertaken using both inductive and deductive approaches. Results Four themes were identified: (1) complex staffing issues deter or impede participation in research; (2) external pressure on the aged care system leads to research not being a priority; (3) funding issues are variable and pose a barrier for some aged care homes; and (4) research processes and requirements can lead to biased samples. Conclusions Several challenges to undertaking quality empirical research in residential aged care in Australia were identified. Research needs to be part of usual business, similar to hospitals, and operate independently of staffing and funding issues. Issues within foodservices are system issues and there is a need for quality empirical research to determine solutions.
