Nutrition and bioanalytical science are closely intertwined. The role of bioanalytical science in nutrition involves the development of advanced analytical techniques to measure nutrients, metabolites, and biomarkers in biological samples. This helps in assessing the nutritional status of individuals and populations, as well as understanding the impact of diet on health. For example, techniques like mass spectrometry and chromatography are used to analyze vitamins, minerals, and other essential nutrients in blood, urine, and tissue samples.
