Cruciferous vegetable diet and 24-hour blood pressure
Do adults with mildly elevated blood pressure have lower blood pressure on a cruciferous vegetable diet than on another vegetable diet?
Human · VESSEL randomized crossover trial
Key findings
Difference in 24-hour systolic blood pressure
The cruciferous vegetable diet was associated with a mean systolic blood pressure 2.5 mmHg lower than the comparison diet (95% CI −4.2 to −0.9 mmHg; p=0.002).
Daytime blood pressure and lipids
Daytime systolic blood pressure contributed most to the difference, and a small difference in triglycerides was also reported.
Dietary effects of different vegetables
The intervention was a diet containing several cruciferous vegetables together.

Study design
Eighteen people followed each of two diets for two weeks, with 17 included in the blood pressure analysis. About 300 g/day of cruciferous vegetables was compared with root and squash vegetables, with a two-week washout between diets.
