Fig. 1. Body weights and SBP of SHR (Expt 1). See figure insert for group designation. Top figure A depicts body weight (BW) of 4 groups eating sucrose/starch or starch diets with and without the addition of 8% w/w cinnamon. Bottom figure B depicts SBP of 4 groups of six SHR each eating sucrose/starch or starch diets with and without the addition of 8% w/w cinnamon. Means ± SEM are shown. Regarding values for BW and SBP, the average of sugar-eating group is significantly different from other three groups for the last two readings.

Fig. 5. SBP of SHR at completion of study (Exp 3). See figure insert for details. Groups of 8 SHR were examined. Means ± SEM are depicted. SBP for Sucrose group is statistically higher than the Starch group, however, the mean SBP of the other sucrose-eating groups also consuming cinnamon, extracts, or chromium are not.
