Researchers make the case for pairing sodium reduction with more potassium from everyday foods.

The next conversation about blood pressure may need to focus on what belongs on the plate as well as what should come off it. Researchers are drawing attention to potassium as a partner to sodium reduction.
A review in the American Journal of Clinical Nutrition argues that public health strategies should give greater attention to increasing potassium while continuing efforts to reduce sodium. The report received renewed news coverage November 2, although the research was published earlier this year.
“Growing evidence shows that increasing dietary potassium as well as reducing sodium intake work together to better manage hypertension,” said lead author Dr. Naomi Fukagawa, a University of Vermont professor emerita, in a university release.
Potassium helps the kidneys remove sodium and supports blood vessel function, the university explained. The review proposes a broader nutritional strategy; it does not establish that one food treats hypertension.
The National Institutes of Health identifies potatoes, spinach, tomatoes, lentils, kidney beans, bananas, milk and yogurt among potassium sources. Many Americans consume less than recommended amounts, according to its Office of Dietary Supplements.
An ordinary vegetable or bean dish can contribute to potassium intake without requiring a specialty product. Choosing a variety of foods also fits the NIH’s guidance on obtaining the mineral through meals.
More is not appropriate for everyone. Kidney disease and medicines such as ACE inhibitors or potassium-sparing diuretics can allow potassium to rise dangerously, even at typical food intakes.
Readers with those conditions should discuss their diet with a clinician before increasing potassium or trying potassium-based salt substitutes. The practical goal is a suitable eating pattern that addresses both nutrients while respecting individual medical needs.
