High-Sodium, Low-Potassium Diet Linked to Heart Risk

Study Suggests Increased Risk of Death From Heart Disease From High-Sodium, Low-Potassium Intake

Eat More Veggies?

Satin points to studies that have found salt reduction is often not linked with much blood pressure reduction.

In his view, paying attention to potassium intake may be enough. "The general public should ignore this study and focus on eating more salads, vegetables, and fruits," he says. He reasons that if people do that, the sodium will take care of itself.

Not so, says New York City Health Commissioner Thomas Farley, MD, MPH. He co-authored a commentary to accompany the study.

"Sodium and potassium were independently associated with mortality," he says. For that reason, he tells WebMD, people would have to lower sodium to reduce their risk of death from all causes.

One way to balance sodium and potassium, he says, is to avoid processed foods. He says as salt is added to processed foods, ''potassium tends to be washed out."

A sweet potato has about 694 milligrams of potassium. Eight ounces of yogurt has 531 milligrams, and a baked potato has 610 milligrams.
