Beetroot Juice May Help Lower Blood Pressure
Beetroot juice has been making news lately as a potential sport drink alternative; especially since the Auburn University football team started drinking it before games. A recent study suggests that beetroot juice may also be good for lowering systolic blood pressure in overweight mature adults.
Participants in the study included 24 overweight participants who were given either beetroot juice or black currant juice daily for three weeks. The participants were also monitored for a fourth week.
The researchers measured blood pressure using three different methods: resting clinic blood pressure, 24-hour ambulatory blood pressure monitoring, and home monitoring of daily resting blood pressure. The first two were used at the onset of the study as well as at the end of weeks three and four. Home monitoring occurred daily.
At the three-week mark, there were no changes registered in 24-hour ambulatory blood pressure monitoring or resting clinic blood pressure. However, the home monitoring revealed a 1.3 mmHg drop in systolic blood pressure.
Researchers from Newcastle University and University of Hertfordshire conducted the study. It was published online ahead of print on September 28, 2014, in the journal Nutrition.
Beetroot juice is packed with nutrients such as folic acid, vitamin C, vitamin B complex, amino acids and calcium. It has been associated in previous studies with lowering blood pressure, improving digestive health, boosting stamina and combating liver problems.
