According to a recent study conducted by British scientists, a cup of * beetroot* juice a day helps bring down the blood pressure. The results were published in the American Heart Association’s journal Hypertension .
The researchers studied vegetables that are rich in nitrates, that is, beetroot, * lettuce* , fennel , and cabbage . These vegetables draw nitrates from the soil. Scientists say that when nitrates get into the body, they turn into nitrogen oxide which results in relaxing of the blood vessels and a lower blood pressure.
