Regular intake of cranberry juice that is low in calorie may help to keep blood pressure under control, finds a new study.
In a study that measured the effects of drinking low-calorie cranberry juice, participants drank either low-calorie juice or a placebo drink every day for eight weeks as part of a controlled diet.
Blood pressure was measured at the beginning, mid-point and end of the study. After eight weeks, blood pressure values had significantly dropped from an average of 121/73 mmHg to 118/70 mmHg for those drinking the low-calorie cranberry juice. The placebo group showed no change.
Researchers noted that cranberry juice is rich in antioxidants - naturally occurring molecules in fruit, tea, wine and other foods - which have been associated with lower blood pressure in other studies.
The study was presented at the American Heart Association's High Blood Pressure Research 2012 Scientific Sessions.
