Sponsor's own description
High blood pressure is the leading cause of cardiovascular disease worldwide. Many medicines are available to lower blood pressures successfully, as well as many non-medical options, such as dietary changes. Some effective dietary changes include decreasing sodium and increasing potassium in the diet. A lot of focus has been on sodium intake yet; potassium intake in the diet remains low amongst adult Canadians. Excellent data exist in the published research reporting that increasing potassium intake, either as diet or even as supplements, reduces blood pressure and reduces risk of cardiovascular outcomes such as stroke. The overall purpose of this study is to reveal the most effective way of increasing potassium, amongst participants with high blood pressure whose existing intake of potassium is low. In the first stage, participants with high blood pressure and proven low potassium intake will receive dietary counselling. If after 4 weeks, there has not been a desired increase in potassium intake, the patients will be prescribed an additional potassium supplement.
