Potassium-rich foods lower blood pressure

Boosting levels of potassium in your diet may lower high blood pressure or prevent you from developing high blood pressure, say researchers from Nashville, Tennessee. 

In this review of recently published studies about diet and blood pressure, the researchers found that many people could lower their blood pressure by more than 10 percent if they increased their intake of potassium-rich foods.

Foods that are high in potassium include: bananas, oranges, orange juice, potatoes, avocado, cantaloupe, tomatoes, tomato juice, chicken, salmon, and milk.

A high intake of potassium dilates blood vessels and protects them from the constricting effects of stress. Low potassium intake can cause the body to retain sodium - a well-known culprit in high blood pressure.

High blood pressure, or hypertension, is defined as blood pressure that's consistently above 140/90 mm Hg.

According to the Heart and Stroke Foundation of Canada, one in five Canadians are affected by high blood pressure.

Because high blood pressure often has no symptoms, an estimated 43 percent of Canadians have this risk factor for heart disease - and aren't aware of it.
