If people eat less salt and more potassium-rich salt, the extra potassium might lower their blood pressure more than cutting back on salt alone — and most of that drop seems to come from the potassium.

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

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.

If adults with high blood pressure eat more potassium-rich foods—like bananas or spinach—by about 50 mmol per day, their blood pressure numbers go down a bit, which might help lower their risk of heart problems.

If you eat less salt but add more potassium to it, your blood pressure might drop more if you usually don’t get much potassium in your diet—because your body gets a bigger boost from the potassium than it loses from the sodium.

When people who don’t eat much potassium switch to salt with extra potassium, their blood pressure drops mostly because they’re getting more potassium—not because they’re eating less salt, since they’re still eating plenty of salt.
