The Claim

In populations with high baseline sodium and low baseline potassium intake, increasing dietary potassium by approximately 20.6 mmol/day and reducing sodium by approximately 15.2 mmol/day is associated with a mean systolic blood pressure reduction of 3.3 mmHg, with the majority of this reduction likely attributable to potassium increase rather than sodium reduction.

In plain English

If you eat more potassium-rich foods and less salty food, your blood pressure might drop by about 3.3 mmHg—and most of that drop probably comes from eating more potassium, not less salt.

  1. Study: The contribution of sodium reduction and potassium increase to the blood pressure lowering observed in the Salt Substitute and Stroke Study

    The study used a special salt with more potassium and less sodium, and found that most of the blood pressure drop came from the extra potassium, not the less sodium — just like the claim said.
