Nutritional assessment tools and techniques are utilized to systematically evaluate an individual's dietary intake, nutritional status, and general health. The assessments combine clinical, anthropometric, biochemical, and dietary measures in a way that provides a comprehensive understanding of nutrition requirements and nutrition risks. Accurate assessment allows nutrition professionals and health care providers to develop specific interventions, monitor patient progress, and minimize the risks associated with poor nutrition. This session will review traditional and modern assessment tools and techniques, including dietary recalls, food frequency questionnaires, body composition techniques, and biomarker analyses. We will emphasize the applied use of these tools in practice and research. Using these tools and techniques together will enhance patient care, promote effective evidence-based practice, and optimize health outcomes.
