SPEAKIN’ OUT NEWS
When people think about controlling high blood pressure, reducing sodium often receives the most attention. However, eating enough potassium may also help the body regulate blood pressure and protect cardiovascular health.
Potassium is an essential mineral that supports normal heart and kidney function, muscle contraction, and nerve transmission. It helps lessen sodium’s effects and relax blood vessel walls. Diets containing potassium-rich foods are associated with healthier blood-pressure levels, particularly when paired with lower sodium intake.
That message is especially important in Alabama, where cardiovascular disease remains a major public-health concern. Nationally, nearly half of American adults have high blood pressure, according to the Centers for Disease Control and Prevention. Uncontrolled hypertension increases the risk of heart attack, stroke, kidney disease, and cognitive decline.
Fortunately, potassium is available in many affordable foods. Good sources include beans, lentils, spinach and other greens, potatoes, sweet potatoes, tomatoes, oranges, bananas, avocados, yogurt, milk and fish. One banana contributes potassium, but it cannot meet an adult’s entire daily requirement.
Current recommended daily amounts are 3,400 milligrams for adult men and 2,600 milligrams for adult women. Most nutrition experts encourage obtaining potassium through a varied diet rather than pills.
More potassium is not safe for everyone. People with chronic kidney disease may be unable to remove excess potassium from their blood, creating a potentially life-threatening condition called hyperkalemia. ACE inhibitors, angiotensin-receptor blockers, and potassium-sparing diuretics may also raise potassium levels. Other diuretics can lower them.
Patients should not use potassium supplements or potassium-based salt substitutes without medical guidance. Food choices can support blood-pressure management, but they should complement—not replace—prescribed medication, regular monitoring, exercise, and professional care.
