Managing blood pressure often involves reducing sodium intake, but new research suggests that potassium is just as important. A recent report published in The American Journal of Clinical Nutrition found that increasing potassium intake while decreasing sodium intake may be the best strategy for managing blood pressure.
According to the report, the average daily sodium intake for American adults remains significantly above the recommended levels. Potassium-rich foods, such as leafy greens, tomatoes, beans, lentils, potatoes, avocados, bananas, and cantaloupe, can help the body regulate sodium balance and support healthy blood pressure.

Potassium plays a significant role in muscle function, nerve signaling, fluid balance, and heart health, in addition to helping regulate blood pressure. Most Americans don’t meet the recommended daily intake of potassium, making it essential to incorporate more potassium-rich foods into their diet.
Melissa Prest, D.C.N., R.D.N., spokesperson for the Academy of Nutrition and Dietetics, explains that potassium-rich foods provide fiber, antioxidants, and other nutrients that support overall health. Filling half your plate with fruits and vegetables, incorporating beans or lentils into meals, and choosing minimally processed foods more often can help increase potassium intake naturally.
In addition to managing blood pressure, a diet rich in potassium can also benefit heart health, gut health, and reduce the risk of several chronic diseases. However, it’s essential to note that a diet rich in potassium may not be suitable for everyone, particularly those with chronic kidney disease or taking certain medications.

Jennifer Wong, M.D., board-certified cardiologist, suggests that people with high blood pressure should consider the balance between sodium and potassium in their diet. Gradually reducing sodium intake while increasing potassium-rich foods can provide additional reductions in blood pressure.
While this new research is a preliminary report, it could change how we think about managing blood pressure. Shifting the conversation from simply “eat less sodium” to “eat more potassium-rich whole foods while also being mindful of sodium” may be the key to better managing blood pressure.
