Sodium: we know we should avoid too much, but why, exactly, and how much is too much?  What about low sodium, is that a problem? This week, we will take a closer look at this essential mineral to understand what it does in our bodies and why we should pay attention to it. 

Potassium: there is much more to this mineral than eating a banana!  Potassium is one of our main electrolytes, acting as a partner with sodium to keep our nerves firing and sending information through our bodies.  Low levels are associated with high blood pressure and heart disease, but a diet full of potassium rich fruits and vegetables can protect against these conditions.
