Objectives: The aim of this qualitative study was to explore and understand the behaviors and challenges of self-nutrition management from the perspective of elderly.Methods: In May 2025, ten elderly aged 65–83 years with prior experience using digital devices were recruited through purposeful sampling. Data were collected via focus group interviews using a semi-structured questionnaire until saturation was reached, and all interviews were recorded, transcribed, and analyzed using traditional content analysis methods. The collected interview data were extracted focusing on phrases or sentences relevant to the research purpose, and various concepts derived through memo writing and the constant comparison were categorized based on common meanings. Subsequently, the categorized statements were deeply interpreted and reclassified into subcategories for final analysis.Results: Under the overarching theme of development directions for a digital self-nutrition management education program for elderly, three main categories and 13 subcategories were derived. The three main categories include: (1) processes of acceptance and utilization of digital technologies; (2) potential for applying digital self-nutrition management; and (3) strategies for implementing digital-based nutrition education.Conclusion: Our findings indicate that elderly face barriers to utilizing digital tools for self-nutrition management not only due to physical or technical limitations, but also because of the confusion arising from limited nutrition knowledge and information overload. To overcome the barriers that may arise during the digital-based education process for elderly, strategies (educational topics, delivery strategies, and operational strategies) were derived to vitalize a digital self-nutrition management education program. These results highlight the necessity of developing tailored digital nutrition education programs that reflect the characteristics of elderly, which may enhance their practical applicability and provide foundational evidence for establishing a digital–nutrition integrated care model within the senior customized care service.
