Background/Objectives: Older adults often face nutrition challenges due to mobility issues, chronic conditions, and limited access to adequate nutrition. Digital and technology-based interventions, including those with nutrition education, nutrition counseling and Medically Tailored Meals [MTMs], can help address these barriers. However, the extent and characteristics of such programs in the United States remain unclear. This scoping review aimed to map the existing evidence on digital and technology-based (“digi-tech”) nutrition interventions for older adults in the United States, with particular attention to the presence, characteristics, and gaps related to MTMs. Methods: This scoping review followed the PRISMA-ScR framework to map existing evidence on technology-enabled nutrition care interventions for older adults aged ≥ 60 years in the United States. Systematic searches were conducted across multiple databases, yielding 18,177 records. Following title and abstract screening, full-text review, and eligibility assessment, 16 intervention studies were included. Study designs comprised randomized controlled trials, quasi-experimental and non-randomized studies, mixed-methods feasibility studies, pilot studies, and one retrospective longitudinal cohort study. Data were extracted on study design, population characteristics, intervention components, technology modalities, outcomes, feasibility, acceptability, and reported barriers. Results: Interventions varied in duration [8 weeks to ≥12 months] and content. Foci ranged from remote nutrition education and mobile app-based tracking to multicomponent interventions integrating exercise, nutrition counseling, health literacy, and meal delivery. Telehealth was the most commonly used technology modality, followed by mobile health applications, wearable devices, and online educational platforms. Most interventions reported high feasibility and acceptability, with improvements in diet quality, adherence to healthy eating patterns, clinical measures such as HbA1c and blood pressure, and functional performance. Common implementation barriers included declining technology use over time, digi-tech literacy, and access to devices or the internet. Notably, no studies evaluated a digi-tech-based MTMs intervention exclusively for older adults in the U.S. Conclusions: Digital and technology-based nutrition interventions show promise for improving dietary and health outcomes in older adults, but there is insufficient empirical evidence. Future research might develop and evaluate hybrid digi-tech intervention models that leverage the potential of digi-tech tools while addressing barriers to technology adoption among older adults.
