| Outline of Final Research Achievements |
We examined the difference in sodium intake according to taste preference. Taste preference for miso soup was associated with 24-hour urinary sodium excretion, with a regression coefficient per 1 rank preference increment of 1g salt/d. Taste preference for miso soup was suggested to be a defining feature of whole sodium intake through discretional salt-related behaviors. Based on these results, we conducted a pilot study of randomized controlled trial. For the intervention, low-sodium miso and soy sauce were provided. A salinity meter was also provided to monitor salt concentration of miso-soup by 2 × 2 factorial design. Changes of 24-hour urinary sodium excretion before and after intervention period were compared. Reduction of salt intake was approximately -2g according to low-sodium seasoning use. This difference was similar to previous studies. Reduction by monitoring salt concentration was -3g.
