Development and application of flavonoid intake assessment methods and the impact of flavonoids on cognitive and physical outcomes

A growing body of evidence suggests that a diet rich in flavonoids, naturally occurring plant-based compounds, is associated with improved health outcomes. However, current knowledge relating to the measurement of dietary flavonoid intake is limited and studies assessing the association of flavonoid-rich food supplementation with cognitive and physical health outcomes are scarce. This doctoral thesis outlines six studies that were developed to address two main research questions. Firstly, what methods should be employed to measure flavonoid intake? Secondly, how does the consumption of dietary flavonoid impact cognitive and physical outcomes?
