Brief Summary

Excess dietary salt intake is closely associated with the development of hypertension and cardiocerebral vascular diseases. Reduction in high salt intake significantly prevents hypertension and cardiocerebral events. Currently, few promising method is available to reduce salt intake in human. This study focus on examining the salty taste in population-level and exploring whether dietary factors can reduce salt intake through acting on salty taste.

Outcome Measures

Primary Outcomes (1)

  • Effects of spicy diet on salt taste

    Daily spicy food intake was evaluated by diet questionnaire and salty taste was tested through salt perception and super-threshold examination on the first day when the participant was investigated.
