• Figure - (TIF) (5.94 MB) Capillary blood glucose during the study. Bars represent capillary blood glucose in a randomly chosen subgroup of patients during the study at baseline, after 30, 60 and 120 minutes after cocoa-free control chocolate (n=6, white bars) and after flavonoid-rich dark chocolate (n=7, black bars). No significant changes in capillary blood glucose were seen after chocolate.
