‘Mild’ increases in salt intake add risk of high blood pressure and heart disease: New data

Even small increases in salt intake that are well within the ranges seen in daily life are linked to a higher risk of high blood pressure, according to new Japanese population data.

According to the authors of the study, which is published in the Journal of the American Heart Association, the new data ​highlights the importance of maintaining a lower-salt diet over a lifetime, and confirms the findings of other studies that show strong associations between salt in the diet and high blood pressure.

Led by Dr Tomonori Sugiura from the Nagoya City University, the team looked at data from more than 4,000 Japanese people, finding, as expected, that those who ate the most salt were the most likely to have high blood pressure by the end of the study, but also that those who gradually increased their sodium intake showed gradually higher blood pressure.

"In our study, it did not matter whether their sodium levels were high at the beginning of the study or if they were low to begin with, then gradually increased over the years -- both groups were at greater risk of developing high blood pressure,"​ said Sugiura.

Japanese study

Posted by Marin Velcev,

Japanese people has one of the longest lifespan in the world. They also have highest per capita salt intake in the world. It looks like that very high sodium intake, together with Japanese lifestyle and food habits are not as harmful as high salt intake combined fore example with junk food. I would also underline that some populations of people, living in stormy seashore areas could have very high sodium intake just from inhalation and swallowing salt.
