Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Correlation

In plain English

If you replace some of the regular salt in your food with a salt substitute that has less sodium, your blood pressure might drop a little — about 1.5 points for the top number and 1 point for the bottom number for every 10% less salt you use.

What the research says

1 study
  1. Study: Effects of salt substitutes on clinical outcomes: a systematic review and meta-analysis

    This study found that when people use salt that has less sodium and more potassium, their blood pressure goes down—and the less sodium in the salt, the more their blood pressure drops. The numbers match exactly what the claim says.
