What do guavas, sweet potatoes and bananas have in common? They’re all great sources of potassium. A wide variety of plant and animal foods contain potassium, as do many of beverages. Managing your potassium intake can help — or hurt your health.

You may be looking for ways help lower blood pressure without medication. Or maybe symptoms of the keto flu have got you down; eating more of the mineral potassium can help.

Eating more potassium-rich foods is a healthy idea for most people. Potassium helps regulate the fluid and mineral balance in and out of body cells. It also helps transmit nerve impulses and helps muscles contract. This electrolyte helps maintain normal blood pressure blunting sodium’s effect on blood pressure. For some, including those with chronic kidney disease, foods with lower amounts of potassium should be eaten.

Most healthy women over age 18 need 2,600 mg of potassium to avoid deficiency; or 2,900 mg while pregnant and 2,800 mg while lactating. Most men 18 years and older need 3,400 mg.

High-Potassium Healthy Foods

Following the Mediterranean Diet or the DASH Diet — both of which are rich in potassium — can help people get their blood pressure into a healthy range. Diets with plenty of potassium can also help lower the amount of blood pressure medication someone needs, or even help go off medication if health indicators improve, and a doctor approves it.
