When you think potassium, do you think of a banana first? Somewhere along the line, bananas became known as the go-to for potassium, when they’re not even the highest potassium provider in the fruit category, let alone vegetable.

Benefits of Potassium

Potassium is one of the 16 essential minerals we get from our diets. Also an electrolyte, potassium helps conduct electrical impulses in our bodies and plays a key role in blood pressure regulation and metabolism. Potassium’s health benefits also include aiding in relief from stress, anxiety, heart and kidney disorders, and stroke.

Low Potassium

If your potassium gets too low, you may develop hypokalemia. A low potassium level can be caused by issues with your adrenal glands, excessive diarrhea, vomiting, or use of diuretics. Low potassium can cause muscle weakness, twitching, cramping, and in more extreme cases, muscle paralysis and abnormal heart rhythms.

High Potassium

Too much potassium is the condition called hyperkalemia. Again, because potassium is so important in regulating your heartbeat, too much potassium can cause possibly deadly changes in your heart rhythm. A proper, balanced amount of potassium is essential to your health.
