If you increase the amount of fruits and vegetables in your diet, you will also lower your blood pressure. Coffee contains caffeine which is a stimulant and can cause your blood vessels to contract and increase your blood pressure. However, this amount is small, and may or may not be significant.
The amount of caffeine in two to three cups of coffee can raise systolic pressure (the top number in your blood pressure reading) 3 to 14 millimeters of mercury (mm Hg). Your diastolic pressure (the bottom number) can be increased 4 to 13 mm Hg. http://www.mayoclinic.com/health/blood-p... Source(s):
