Hypertension is associated with taking the amount of sodium and potassium intake. Though dietary salt reduction has been introduced as a way of nutritional counselling, increasing potassium has not been recognized. Recently, urinary sodium and potassium ratio could be measured by the portable device. Through the measurement of urinary sodium and potassium ratio, we compare the nutritional counseling by reducing dietary salt with by salt reduction and increasing potassium.

Unpublished
In December 2015, the intervention on the small scale was carried out. The number of subjects registered was 2 (male) and it was confirmed that there was no problem in the intervention protocol in the work area.
The target was recruited from January to February 2017, and the actual intervention was conducted in January to March of the same year divided into 6 courses. The number of new registrants was ten (total of 13 registered as of November 20, 2017). The urinary sodium potassium ratio showed a downward trend in both groups in the 2 weeks of the study period. There was no statistically significant difference before and after the intervention of both groups and each group, but the urinary sodium potassium ratio fell more in the intervention group than in the control group.
