Personalized nutrition interventions using digital technologies for older adults: a scoping review
Soyoung Jung, Hae Jin Kang, Yoo Kyoung Park
Clin Nutr Res 2026;15(3):228-241.   Published online July 31, 2026
DOI: https://doi.org/10.7762/cnr.2026.0027

Objective

As global populations age, nutrition management is important for healthy aging. Digital technologies, including mobile applications, web-based platforms, messaging tools, and artificial intelligence (AI)-enabled systems, are used in personalized nutrition interventions. However, evidence on their characteristics, effectiveness, and user experiences remains limited. This scoping review examined technology-based personalized nutrition interventions for older adults.
Methods
This review followed the Joanna Briggs Institute methodology and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines. PubMed, Embase, and Web of Science were searched for studies published from January 1, 2010, to June 30, 2026. Among 2,727 records, 2,044 were screened after duplicate removal, 28 full-text articles were assessed, and 13 articles representing 12 studies were included.
Results
Technologies included mobile, messaging, web-based, information and communications technology, tablet-based, and AI-supported systems. Interventions involved dietary recording, personalized feedback, remote counseling, coaching, and self-monitoring. Outcomes included dietary intake and quality, nutritional status, physical function, frailty, cognition, cardiometabolic indicators, engagement, usability, and acceptability. Findings were more consistent for dietary behaviors and individualized nutrition management. Evidence for physical function, frailty, cognition, cardiometabolic health, and quality of life was limited and often based on small or multidomain studies. Familiar interfaces and professional support were accepted, whereas low digital literacy, complex navigation, and limited food databases were barriers.
Conclusion
Digital personalized nutrition interventions may support dietary behavior change and individualized nutrition management in older adults. Larger studies and user-centered systems addressing digital literacy, usability, cultural context, and AI-feedback validation are needed.

Toward a longevity diet framework: integrating global evidence for healthy aging in the South Korean population
Soyoung Jung, Hae Jin Kang, Mijoo Choi, Yoo Kyoung Park
Clin Nutr Res 2026;15(2):91-100.   Published online April 30, 2026
DOI: https://doi.org/10.7762/cnr.2026.0015

Objective

As global life expectancy rises, the focus has shifted from longevity alone to healthy aging. Although dietary models such as the Mediterranean, Dietary Approaches to Stop Hypertension (DASH), Mediterranean-DASH Intervention for Neurodegenerative Delay, and EAT-Lancet diets show benefits for specific health outcomes, their direct application to South Korean populations is limited by differences in dietary patterns and cultural practices. This study aimed to develop nutritional criteria for a South Korean-adapted longevity diet framework. Methods: A multiphase development approach was used, including a narrative review of major dietary models and clinical nutrition guidelines to identify key components of a longevity diet. Macronutrient distribution, food group intake, and nutrient-specific recommendations were synthesized into a structured framework. The EAT-Lancet reference diet was adjusted from 2,400 to 2,000 kcal/ day to reflect energy requirements of South Korean adults. Results: The proposed framework comprises six domain-specific recommendations, including macronutrient targets of 50%–65% carbohydrates, 10%–20% protein, and 15%–30% fat, with a 1:1 animal to plant protein ratio. Food group recommendations were tailored to South Korean dietary patterns. The framework addresses weight management, glycemic control, cardiovascular health, cognitive function, muscle function, and skin health. It emphasizes whole grains, dietary fiber, plant-based proteins, and unsaturated fats, while limiting refined carbohydrates, added sugars, and saturated fats. Conclusion: This study presents evidence-based nutritional criteria for a South Korean-adapted longevity diet framework that integrates disease prevention with functional health support to promote healthy aging.

Food for Special Medical Purposes: A Global Review of Usage Trends, Regulatory Frameworks, and Key Growth Drivers
Hae Jin Kang, Yoo Kyoung Park
Clin Nutr Res 2025;14(2):146-156.   Published online April 28, 2025
DOI: https://doi.org/10.7762/cnr.2025.14.2.146

This review offers a comprehensive analysis of food for special medical purposes (FSMPs)—specially formulated foods designed to support the dietary management of individuals with specific medical conditions. The regulatory frameworks governing FSMP differ significantly across key regions, including the European Union, North America (with a focus on the United States), and Asia (primarily China and India). FSMP is critical in addressing malnutrition, metabolic disorders (including inborn errors of metabolism), and chronic diseases, such as cancer, diabetes, and neurological conditions. Recent advancements, such as the application of three-dimensional printing technology and the growing emphasis on personalized nutrition, are poised to revolutionize the FSMP industry. The global market for FSMP is experiencing rapid growth, particularly in China, driven by factors like aging populations and the increasing prevalence of chronic diseases. Future trends suggest a shift toward more personalized, technologically advanced FSMP formulations. However, challenges such as high costs, limited accessibility, unclear regulations, and poor palatability must be addressed to maximize the potential of FSMP in enhancing patient care.

Snack Provision Practice in Long-Term Care Hospitals and Facilities in Korea
Dayeong Yeo, Hae Jin Kang, Hyejin Ahn, Yoo Kyoung Park
Clin Nutr Res 2024;13(2):108-120.   Published online April 30, 2024
DOI: https://doi.org/10.7762/cnr.2024.13.2.108

The study aimed to investigate the basic data to derive plans for snack provision to improve the nutritional status of older adults living in long-term care facilities (LFs) or long-term care hospitals (LHs). The 252 respondents (118 from LHs and 134 from LFs) were included in the study. The questionnaire of nationwide cross-sectional survey was developed by the authors and registered dietitians. The written questionnaire was sent to the food service managers across 800 LFs or LHs. The online survey was introduced using the online platform and network site for dietitians. More than 70% of live-in and non-live-in LFs provided snacks, which were mainly provided one to two times a day. Most institutions provided fruits one to three times a week. The main considerations when providing fruit were in the order of residents’ preference, cost, and ease of consumption. The reasons for not serving fruit included cost and differences in the residents’ eating and mastication abilities. Most institutions also provided dairy products at a frequency of one to three times a week. The reasons for not serving dairy products included cost and the lack of awareness of the need to provide them. To improve the quality of life and the offer benefits of fruits and dairy products to older people, efforts are needed to propose a plan to expand the provision of snacks in appropriate quantities and varieties.
