LET'S HEAR IT FOR THE NUT!
They're loaded with energy, filled with antioxidants, vitamins and minerals....Oh! Oh!  One of the minerals they're loaded with is potassium.

Potassium is great for controlling heart rate and blood pressure.  Alas, you have to get rid of excess potassium or it will settle in your bones and turn them to mush.

If your kidneys are failing, your body can't get rid of that extra potassium and mushy bones suck which means no blueberry walnut pie for me.

Another one of the perks of living in your "golden years".
