Potassium

We all know that bananas are a great source of potassium, but what the heck do we need potassium for in the first place?

The question is, what doesn't potassium do? This mineral is an electrolyte, which means it maintains the body's fluid levels. It helps to regulate blood pressure and heart function. Those with hypertension can benefit from potassium because it counters the effects of sodium. Potassium neutralizes acids in your body (think of all the coffee and soda you're drinking!), helps with arthritic problems, headaches and migraines, is a natural pain desensitizer, and is crucial for waste elimination.

AKA, we all need postassium, and lots of it. Bananas aren't the only snack with loads of the stuff... try sweet potatoes, tomatoes, yogurt, prunes, carrots, tuna, cod, spinach, peaches, apricots, and milk.
