Eat Fruit to Ease Arteries

Beetroot Juice

Researchers think they've discovered why a diet rich in fruit and vegetables helps reduce blood pressure. Bacteria in the mouth convert the nitrates found in these foods into nitric oxide, which helps to protect the blood vessels.

This was tested in one London study, where people who drank half a liter of beetroot juice experienced a substantial drop in blood pressure within hours. Other dietary tips if you have high blood pressure: reduce your salt intake, lower your weight and avoid alcohol - even moderate drinking may raise blood pressure more than previously thought.

Research also shows that people with a diet rich in low-fat dairy foods have less chance of developing high blood pressure.
