Potassium is a very important mineral for the proper function of all cells, tissues, and organs in the human body. It is also an electrolyte, a substance that conducts electricity in the body, along with sodium, chloride, calcium, and magnesium.
It is one of the main blood minerals called electrolytes (the others are sodium and chloride), which means it carries a tiny electrical charge (potential). Potassium is the primary positive ion (cation) found within the cells, where 98 percent of the 120 grams of potassium in the body is found. Magnesium helps maintain the potassium in the cells, but the sodium and potassium balance is as finely tuned as those of calcium and phosphorus or calcium and magnesium. Research has found that a high-sodium diet with low potassium intake influences vascular volume and tends to elevate the blood pressure. Having too much potassium in the blood is called hyperkalemia; having too little is known as hypokalemia. Keeping the right potassium balance in the body depends on the amount of sodium and magnesium in the blood. Too much sodium -- common in Western diets that use a lot of salt -- may increase the need for potassium. Good sources of potassium include bananas, citrus juices (such as orange juice), avocados, cantaloupes, tomatoes, potatoes, lima beans, flounder, salmon, cod, chicken, and other meats. Elson Haas M. MD ©. Potassium is a very significant body mineral, important to both cellular and electrical function. It is one of the main blood minerals called electrolytes (the others are sodium and chloride), which means it carries a tiny electrical charge (potential). Potassium is the primary positive ion (cation) found within the cells, where 98 percent of the 120 grams of potassium in the body is found. This mineral is also lost with vomiting and diarrhea. Sources: Potassium is found in a wide range of foods. Many fruits and vegetables are high in potassium and low in sodium and, as discussed, help prevent hypertension. Potassium is a mineral that plays many critical roles in the body. Food sources of potassium include fruits (especially dried fruits), cereals, beans, milk, and vegetables. Potassium is used for treating and preventing low potassium levels. It is also used to treat high blood pressure and prevent stroke.  Potassium is a very important mineral for the proper function of all cells, tissues, and organs in the human body. It is also an electrolyte, a substance that conducts electricity in the body, along with sodium, chloride, calcium, and magnesium. Potassium is crucial to heart function and plays a key role in skeletal and smooth muscle contraction, making it important for normal digestive and muscular function. Good sources of potassium include bananas, citrus juices (such as orange juice), avocados, cantaloupes, tomatoes, potatoes, lima beans, flounder, salmon, cod, chicken, and other meats. The most important use of potassium is to treat the symptoms of hypokalemia (low potassium), which include weakness, lack of energy, muscle cramps, stomach disturbances, an irregular heartbeat, and an abnormal EKG (electrocardiogram, a test that measures heart function). Good sources of potassium include bananas, citrus juices (such as orange juice), avocados, cantaloupes, tomatoes, potatoes, lima beans, flounder, salmon, cod, chicken, and other meats. Potassium is an essential dietary mineral and electrolyte. The term electrolyte refers to a substance that dissociates into ions (charged particles) in solution, making it capable of conducting electricity.  This mineral is also lost with vomiting and diarrhea. Sources: Potassium is found in a wide range of foods. Many fruits and vegetables are high in potassium and low in sodium and, as discussed, help prevent hypertension. Magnesium helps maintain the potassium in the cells, but the sodium and potassium balance is as finely tuned as those of calcium and phosphorus or calcium and magnesium. Research has found that a high-sodium diet with low potassium intake influences vascular volume and tends to elevate the blood pressure. Potassium is a mineral found in foods. It is also an electrolyte, which conducts electrical impulses throughout the body. Potassium assists in a range of essential body functions, including: 1  blood pressure. 2  normal water balance. 3  muscle contractions. 4  nerve impulses. 5  digestion. 6  heart rhythm.  Potassium It's certainly important to have enough potassium into your system. Potassium is important for nerve and muscle functions, can aid in reducing hypertension and treating allergies, and a deficiency of potassium can result in hypoglycemia. Potassium is a mineral that acts as an electrolyte in the body, carrying nutrients into your cells and wastes out of them.
