FIGURE 3. Effects of either dark chocolate (A and C) or white chocolate (B and D) on sitting systolic and diastolic blood pressure in 15 healthy subjects. No significant differences were found between the “before” values (baseline), which indicated the absence of a carryover effect. In contrast, systolic blood pressure was significantly lower (P 0.05, paired t test) after dark than after white chocolate ingestion. No significant differences in diastolic blood pressure were observed between treatments. In all panels, the symbols represent means, and the vertical lines represent SDs.
