Fig. 1From: Impact of flavonoid-rich black tea and beetroot juice on postprandial peripheral vascular resistance and glucose homeostasis in obese, insulin-resistant men: a randomized controlled trialEffects of tea, beetroot juice and control on VR. VR was assessed by blood flow corrected for BP of conduit arteries at (a) arm and (b) leg, of resistance vessels at (c) arm and (d) leg and of microvessels (e) at the arm. Measurements were taken before and every 30-min (for 3-h) after 75-gr glucose intake in obese, insulin-resistant men (n = 16). Data are presented as mean ± SEM. * significant at P < 0.05; ** significant at P < 0.01; *** significant at P < 0.001 as compared to the mean over time of control treatmentBack to article page
