Several studies have emphasized the crucial role of protein and energy in preventing adverse health outcomes in older adults such as sarcopenia and undernutrition. However, previous researches revealed that protein and energy intake often fall below recommended levels in older population. Given the prevalent shortfall in intake and associated health risks, interventions are needed to support older adults in meeting nutritional requirements. Foodbased fortification, which involves enhancing the nutritional content of commonly consumed foods by adding essential nutrients (i.e. fortificants) emerges as a promising solution. Specifically, the concept of "do it yourself" (DIY) fortification presents a unique opportunity for older adults and their caregivers to tailor nutritional enhancements to individual preferences and eating habits. However, it remains underused and unknown. A recent systematic literature review identified 44 original studies (Geny et al., 2023), setting the stage for a meta-analysis on the impact of DIY fortification on nutritional intake and status. Main eligibility criteria will include older adults aged ≥ 60 years living in various settings (at home, nursing home, hospital). Both randomized and non-randomized controlled trials will be considered. This meta-analysis aims to provide insights into the effectiveness of DIY fortification, offering a practical approach to enhance nutrition among older adults.
