Abstract

Data analysis is crucial in nutrition and dietetics research to understand community implications and implement effective health interventions. It uses techniques like statistical modeling, data mining, and machine learning algorithms to detect patterns and trends in data. Nutritional data can be classified into biomarker data, macro and micronutrient data, and dietary intake data. Methods for data analysis include descriptive statistics, inferential tests, and multivariate analysis techniques. However, methodological challenges like data quality, inconsistency, and validation remain. This review highlights the crucial importance of strong statistical approaches in improving the accuracy of dietary evaluations and guiding public health policy by combining recent research and case studies. Our results support the implementation of standardized procedures and the ongoing development of analytical instruments to raise the caliber and dependability of nutritional research.
