Which data type is included in biochemical data in nutrition assessment?

• A. Hair color.
• B. Body temperature.
• C. Exercise routine.
• D. Blood nutrient levels.

Answer: (D)

Biochemical data are lab measurements that reveal how nutrients are actually functioning in the body. In nutrition assessment, this category specifically includes analyses of biological fluids to quantify nutrient levels or related metabolites. Blood nutrient levels are the key example, since blood tests can show the status of vitamins and minerals (like iron, vitamin D, B12), as well as metabolic markers such as glucose or lipids. These values provide objective evidence of deficiency, sufficiency, or excess and can detect issues before symptoms appear. Other options aren’t biochemical measurements: hair color isn’t a nutrient-related lab measure; body temperature is a vital sign; exercise routine reflects behavior, not a laboratory assessment of nutrient status.
