Twelve Weeks of Vegetable Juice Consumption Decreases Blood Pressure in Individuals with Diastolic Blood Pressure > 80 mm Hg and/or Systolic Blood Pressure > 120 mmHg. Subjects consuming 8 or 16 fluid ounces of vegetable juice were combined into a single group to examine systolic (A), diastolic (C) and mean arterial pressures (E). Systolic (A and B), diastolic (C and D), and mean arterial (MAP; E and F) pressure of subjects who consumed either 8 or 16 fluid ounces of vegetable juice for 12 weeks. Those who started the study with blood pressures greater than 120 mmHg systolic (A) and/or 80 mmHg diastolic (C) demonstrated a significant decrease in blood pressure over the 12-week period, including MAP (E). Those who had normal pressures at the start of the study demonstrated no significant change in blood pressure over the 12-week period (B, C and F). * Significant from baseline p < 0.05 (Repeated Measures ANOVA, Tukey post hoc). ** Significant from baseline, and 6 weeks (p < 0.05; Repeated Measures ANOVA, Tukey post hoc).
