Okay so now we want to talk about the potassium aspects as related to the Dash diet. What researchers also found was that using foods high in potassium actually lowered the blood pressure as well, because this was an aspect of the Dash diet. These are some fruits that are actually high in potassium. And the proposed mechanism behind how this is working is based on volume. Because the renal system, potassium is important in regulating the renal systems balance of fluids. And so what they proposed was that the diet actually replaced potassium for sodium, and sodium always follows water in the renal system and so when you're decreasing your sodium intake you're decreasing your retention of water. And so that was a proposed mechanism there. What I want to point out here is, again, it's not a potassium supplement, and with potassium you can actually cause serious problems by taking too much potassium. So be careful, taking fruits and vegetables in whole fruit form will not harm you. So that's a safe effective dose of potassium and don't go out and get a supplement of potassium. Next we'll be talking about magnesium.
