NUTRITION WHY’S #39: WHY POTASSIUM? Potassium is found inside all the cells of your body where it is the most abundant mineral. 98% of the potassium in the body is inside cells and is put there by an energy-requiring pump in the cell membrane which keeps sodium outside the cell and potassium inside. Blood levels of potassium are carefully controlled by the kidney through the action of aldosterone a hormone from the adrenal glands above your kidneys which activates a pump in the kidney which allows the body to get rid of extra potassium. A high potassium reading in a blood sample is often caused by broken red blood cells either from the sample being drawn quickly through a thin needle or because the sample was left out too long before being processed to remove the red blood cells. A repeat sample usually clears up the confusion. Kidney failure and Diabetes with low Aldosterone are the most common causes of true high potassium levels which can affect heart and muscle cell function. The recommended intake or RDA of potassium is 4700 milligrams or almost 5 grams per day. Having a proper balance of potassium to sodium helps support healthy blood pressure. Eating fruits and vegetables is the easiest way to balance your potassium to sodium ratio and reach the RDA since fruits and vegetables are rich in potassium and low in sodium. Eating foods rich in potassium helps to block the effects of sodium on your blood vessels and is one step beyond restricting high salt snack foods that can help lower your blood pressure or keep it in the normal healthy range. Weight management, Balanced Nutrition, and a Healthy Active Lifestyle work together to keep your blood pressure where it should be which I will discuss in my next post!! #drdavidheber #minerals #potassium #bloodpressure #sodium #salt to learn more go to and
