Understanding nutritional assessment means looking at three interconnected elements: what the person eats and how their body uses nutrients, the physical signs that nutrition is affecting the body, and objective laboratory data that indicate nutritional status. History taking reveals typical intake, appetite, eating patterns, medications, and factors that influence nutrition such as illness or socioeconomic barriers. The physical exam identifies indicators of malnutrition or nutrient deficiencies, such as muscle wasting, edema, skin and hair changes, and functional status. Biochemical data provide measurable evidence—labs that reflect protein stores, micronutrient levels, and metabolic status. Imaging and labs alone don’t capture intake patterns or physical manifestations, and focusing only on dietary restrictions ignores actual consumption and how the body is responding. Exercise tolerance testing assesses fitness, not nutritional status. So combining history, physical examination, and biochemical data gives the complete picture of nutritional health.
