diet management system (samar): a software for evaluating and designing the diet of iranians

Background: dietary intake assessment is a critical component of the nutrition care process, essential for identifying nutritional deficiencies and formulating effective interventions. accurate analysis requires access to a reliable food composition database that reflects cultural and regional dietary habits. in iran, existing software solutions fall short in adequately representing traditional foods, highlighting the need for a localized database. the samar software addresses this gap by enabling users to monitor nutrient intake and tailor dietary plans to better meet the nutritional needs of the iranian population.methods: we conducted a comparative analysis of food intake data from 30 patients using the samar system and the nutritionist 4 (nut4) system. after inputting the data into both software platforms, we compared the results. the normality of the data was assessed using the shapiro-wilk test, and pearson or spearman correlation coefficients were computed. to evaluate the relationship between the values derived from each system, we reported the linear regression model alongside the bland-altman diagram.results: the comparative analysis between the samar software and nut4 demonstrated a strong agreement in nutrient analysis results, indicating that samar is suitable for nutritional assessments within iranian contexts. samar exhibited a direct correlation with nut4 regarding energy and nutrient content. the linear regression models revealed significant relationships for the majority of the nutrients analyzed. the user-friendly interface of samar, along with its compatibility with iranian dietary patterns, renders it a valuable resource for nutritionists and researchers. additionally, the software's capacity to incorporate local foods enhances its functionality, making it more effective than other software applications. conclusion: samar uses the iranian food database. the observed positive correlation between samar and nut4 in nutrient analysis underscores the reliability and user-friendliness of samar for dietary intake assessment in iran.
