Nutrient utilization is a field of research that focuses on the ways in which organisms, typically animals or plants, absorb, metabolize, and utilize nutrients to maintain their growth, development, and overall health. This research area explores the bioavailability and effectiveness of various nutrients, such as vitamins, minerals, carbohydrates, proteins, and fats, in different organisms and how they are utilized in various physiological processes. Researchers in this field investigate factors that may affect nutrient utilization, such as diet composition, digestion and absorption mechanisms, metabolic pathways, and genetic variations. Improved understanding of nutrient utilization can help in developing more effective dietary recommendations, formulations, and interventions to optimize health and address nutritional deficiencies.
