Medical Nutrition Therapy (MNT) involves the assessment and treatment of medical conditions through tailored dietary interventions, administered by a nutrition professional. These professionals undergo higher education and rigorous training, including supervised practice and national examinations, to provide evidence-based nutritional guidance for managing diseases such as diabetes, cardiovascular conditions, gastrointestinal disorders, chronic conditions, and more.

Personalized nutrition (PN) refers to customizing dietary recommendations based on an individual's unique characteristics, including genetic makeup, lifestyle, and health status. This approach aims to optimize health outcomes by considering personal factors that influence nutrient metabolism and dietary needs.​

MNT and PN complement each other by combining clinical expertise with tailored dietary strategies to optimize health outcomes. MNT provides evidence-based nutritional interventions to manage and treat medical conditions, while PN enhances these interventions by incorporating an individual's genetic, metabolic, and lifestyle factors. Together, they create a comprehensive, patient-centered approach that not only addresses existing health conditions but also promotes long-term well-being through precision nutrition.
