The Claim
In Chinese adults, greater reductions in the 24-hour urinary Na+/K+ ratio over a 3-year period were associated with progressively smaller increases in both systolic and diastolic blood pressure, with individuals achieving the largest reduction (≥4.0 mmol/mmol) showing no net increase in diastolic blood pressure and only a 5.3 mm Hg rise in systolic blood pressure.
What the research says
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.
People in China who lowered the balance of salt to potassium in their urine the most over three years ended up with much smaller increases in their blood pressure — some didn’t even see their bottom number (diastolic) go up at all, and their top number (systolic) only rose a little.

What the research says
1 studyPeople who used a special spoon to put less salt in their food lowered their salt levels in urine, and their blood pressure didn’t rise as much — just like the claim says.
