The Claim
In Finland, a one-third reduction in average salt intake over a 30-year period was associated with a more than 10-mm Hg decline in population-average systolic and diastolic blood pressure and a 75% to 80% reduction in stroke and coronary heart disease mortality.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In Finland, when people ate about one-third less salt over 30 years, their blood pressure dropped by more than 10 points, and far fewer people died from strokes and heart disease.

What the research says
1 studyStudy: Sodium intake and hypertension.
The study says that when Finns ate less salt over 30 years, their blood pressure dropped a lot and far fewer people died from heart attacks and strokes — exactly what the claim says.
