Potassium deficiency is actually very common. It's extremely hard to get the recommended daily amount of potassium in your diet, as even high-potassium foods like bananas contain only ten or fifteen percent of the recommended daily intake per serving.
As far as I can tell, this is mainly a problem due to modern farming practices resulting in less nutritious produce; there have been studies done on the vitamin mineral content of food over the last century, and there has been a steady decline in a number of different nutrients, including potassium.
The trouble is, it's also hard to supplement. To avoid stomach issues, over the counter potassium supplements are limited to 99mg in the US, which is only a few percent of the recommended daily intake. If anyone has any good suggestions on how to regularly get enough potassium, I would love to hear them.
