Abstract

Flavonoids are a large and complex group of phenolic compounds present in plant origin foods that may promote health and prevent diseases in humans. Traditional methods to estimate flavonoids intake are based on self-reported questionnaires and food composition databases. These instruments not only are fast, cheap, and practical, but also have certain limitations when estimating the real dietary exposure to flavonoids. However, measurement of flavonoids and their metabolites in biological fluids such as blood and urine may overcome these limitations. Although there are different analytical methods and instruments that can identify and quantify the different flavonoid subclasses, both liquid and gas chromatography coupled or not to mass spectrometry are, currently, the most commonly used methodologies. This chapter summarizes the current literature on these and other innovative technologies for the analysis of flavonoids in human biospecimens, as well as their application in nutritional studies evaluating the exposure to these compounds and their relationships with diseases.
