Option 1
Part 1: Potassium
Potassium is an essential element for the proper functioning of living cells. Maintaining proper K+ levels in the body is important for many vital functions such as heartbeat regulation, proper functioning of muscle and nerves and utilizing and metabolizing macronutrients such as protein and carbohydrates. When someone’s K+ levels are low it can affect the blood pressure and stroke risk. The more K+ you eat, the more sodium that gets excreted through your urine. By lowering your blood volume with the exit of Na+ and H20, you decrease the pressure on the blood vessel walls. In addition, when blood pressure is controlled, you will also decrease your stroke risk.
On the extreme end, potassium is an electrolyte and when there is an electrolyte imbalance the results can be critical. Hypokalemia and hyperkalemia can lead to alkalosis or acidosis with both being deadly.
