The Claim
In a population-wide salt-reduction campaign among Chinese adults, a 32.2% average reduction in urinary Na+/K+ ratio was observed over three years, with the largest reductions occurring in individuals with higher baseline blood pressure, suggesting that sodium reduction interventions may have the greatest impact on those at highest cardiovascular risk.
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.
In China, when people were encouraged to eat less salt over three years, their urine showed a big drop in salt relative to potassium—and the people who started with high blood pressure saw the biggest changes. This suggests cutting salt might help those at highest risk for heart problems the most.

What the research says
1 studyThe study found that when Chinese people used special spoons to use less salt in cooking, their urine showed less sodium and more potassium — meaning they ate less salt. People who started with the highest salt intake also saw the biggest drop in blood pressure, which is exactly what the claim says.
