Advanced Nutrition
Bioelectrical impedance analysis (BIA) is a technique used to estimate body composition, specifically body fat and lean mass, by measuring the resistance of electrical flow through body tissues. This method is based on the principle that different tissues in the body (fat, muscle, and water) conduct electricity differently, allowing for an estimation of overall body composition. It is particularly relevant for assessing nutritional status and effectiveness of enteral and parenteral nutrition support, as it can help monitor changes in body composition during treatment.
congrats on reading the definition of bioelectrical impedance analysis. now let's actually learn it.
