Background & aims Flavonoids may have cardioprotective effects, but epidemiological
evidence on the relationship of dietary flavonoids with diabetes has not been systematically
assessed. To examine the association between dietary flavonoids and type 2 diabetes, we
performed a meta-analysis on this topic. Methods We searched PubMed through March
2013 for relevant cohort studies that assessed total flavonoids and type 2 diabetes risks. A
fixed-effect model was used to calculate the summary risk estimates. Results Four articles …

Epidemiological studies exploring the role of flavonoids intake in preventing type 2 diabetes
mellitus (T2DM) showed inconsistent results. Therefore, we performed a meta-analysis of
relevant studies to examine the relationship between flavonoids intake and risk of T2DM. We
hypothesized that flavonoids intake may decrease the risk of developing T2DM.
