A lack of potassium can lead to muscle cramps. Bananas, lima beans, soy beans and yams all have an abundance of potassium. Humans need potassium to survive. If potassium levels in the body get too high or too low, the heart and nervous system will shut down completely.

Potassium is the third most abundant mineral in the body and has many important functions. A high potassium diet can dramatically benefit kidney function. Potassium can also help the blood vessels open more efficiently. Consuming the RDA of potassium can decrease the risk of kidney stones.

Potassium plays a key role in lowering blood pressure to a healthy level. A potassium deficiency can cause heart palpitations and even diabetes. When the body has high levels of potassium, it allows more oxygen to reach the brain, thus reducing the risk of stroke.
