The convergence of Social Internet of Things (SIoT) technologies and behavioral health strategies offers promising avenues for promoting healthier eating habits. SIoT, which integrates social interactions with IoT, enables smart devices to communicate and collaborate in ways that simulate human social relationships. This emerging paradigm has the potential to transform dietary behaviors by leveraging personalized data, real-time feedback, and social influence mechanisms. Future trends in SIoT could involve advanced systems that use edge computing and AI to provide tailored dietary recommendations, monitor nutritional intake, and foster community support for healthy eating. However, the implementation of SIoT in promoting healthier eating faces several challenges, including data privacy concerns, the need for seamless interoperability among diverse devices, and the ethical considerations of using social data for behavior modification. This review explores the intersection of SIoT and dietary behavior, addressing current advancements, evaluating the effectiveness of behavioral approaches supported by SIoT, and identifying key obstacles that must be overcome to enhance the impact of these technologies on healthier eating practices. By examining these aspects, we aim to provide a nuanced understanding of how SIoT can be leveraged to support better eating habits and contribute to overall public health improvements. The integration of smart devices, the Internet of Things (IoT), and social networking is poised to revolutionize healthcare by enhancing the efficiency and effectiveness of various applications and services. This transformation is further advanced by the emerging concept of the Social Internet of Things (SIoT), which merges social interactions with IoT. SIoT represents a paradigm where objects, akin to humans, possess social attributes and engage in relationships to fulfill their needs, thereby improving performance and efficiency. This investigation underscores the importance of addressing these challenges to fully harness the potential of SIoT in revolutionizing healthcare delivery.
