I was under the impression that many Finns have a genetical risk of hypertension. Thus studies about the link between salt intake and hypertension have been conducted, for example <a href="http:&#x2F;&#x2F;www.ncbi.nlm.nih.gov&#x2F;pubmed&#x2F;17046432" rel="nofollow">http:&#x2F;&#x2F;www.ncbi.nlm.nih.gov&#x2F;pubmed&#x2F;17046432</a>. I haven&#x27;t actually read the paper, but the abstract has this claim:<p>&quot;During the past 30 years, the one-third decrease in the average salt intake has been accompanied by a more than 10-mm Hg fall in the population average of both systolic and diastolic blood pressure, and a 75% to 80% decrease in both stroke and coronary heart disease mortality in Finland.&quot;
