Purpose: Malnutrition is common in residential care environments, primarily due to poor intake. Micronutrient deficiency, although poorly investigated to date, is also reported to be high. Improving the nutrient density of consumed foods is a potential mechanism to promote increased nutrient intake. A scoping review was conducted to: (1) explore the evidence on micronutrient food fortification strategies, (2) identify candidate nutrients and food vehicles for successful food fortification, and (3) identify gaps for future research.

Methods: The scoping review framework of Arksey and O'Malley was used. A comprehensive search strategy of 4 electronic databases (MEDLINE, EMBASE, CINAHL, and Web of Science) was completed. Two reviewers were involved in screening and data extraction for all selected articles.

Results: A total of 4394 relevant articles were identified for screening, and application of inclusion/exclusion criteria resulted in 6 food fortification studies (8 citations; 1 study had 3 citations). Overall, vitamin D (n = 5 studies) and calcium (n = 4 studies) were the most common micronutrients fortified; milk products, margarine, bread, and pureed foods were fortification vehicles. Most studies fortified below the RDA recommendation and did not include clinical outcomes. Samples were small and intervention periods were short (3-6 months).

Conclusions: Fortification is a viable strategy for improving the nutrient density of foods consumed in residential care. Although disparate, this literature suggests the potential for further undertaking of fortification to prevent micronutrient deficiencies among residents and future research should consider multinutrient preparations and clinical outcomes.
