Nutritional assessment involves analyzing anthropometric, biochemical, clinical and dietary data to determine a person's nutritional status. It aims to assess nutritional status, identify body nutrient needs, and recognize health issues related to nutrition. The assessment consists of gathering dietary history, conducting a physical exam, and reviewing laboratory tests. The physical exam includes anthropometric measurements like height, weight and BMI. Laboratory tests examine albumin, hemoglobin and other biochemical indicators. Comparing well-nourished and malnourished individuals identifies key differences in physical and mental characteristics.
