High blood pressure is one of the biggest threats to our health today.

Blood pressure refers to how blood is pushed around the arteries, and high blood pressure causes the arteries to become hardened.

It can be caused by factors such as high salt intake, eating too much processed food, being overweight or having diabetes, and in some cases it is familial.

Dr Ray Walley joined us for our weekly medical consultation to discuss the issues associated with both high and low blood pressure, and the overuse of vitamin supplements.
