Document Summary
The interpretation of information obtained from dietary, biochemical, anthropometric and clinical studies (gibson, 1990) Disease state or use of a drug/substance that do not absorption, excretion, or nutrient activity in the body (in some cases, destroys the nutrient) Mr. x is 6"4 and weighs 260 lbs (pounds). 1 = 2. 54 cm; 1" = 30 cm. 1 lb =. 454 kg (or 1 kg ~ 2. 2 lbs) Biochemical tests on tissue or fluid samples (e. g. , blood, urine) can detect levels of certain nutrients. Samples contain nutrients, enzymes and metabolites that reflect nutritional status. Dark adaptation tests - assess vitamin a deficiency. Capillary fragility tests assess vitamin c deficiency. Bioelectrical impedance analysis (bia) electrical resistance in body inversely proportional to total body water. Gives very important insight regarding one"s nutritional status. Can physically see any signs of over- or undernutrition. Note: estimate versus measure : potential sources of error: Interpretation of findings : obtaining accurate information .
