- Other: salt restriction education
Salt intake target：＜5g/d Method：the standard salt restriction education will be lasting for 10-15 minutes by oral explanation at baseline.
- ratings of taste sensitivity assessed by the ISO method of investigating sensitivity of taste（ISO 3972:1991） [ Time Frame: up to 12 weeks after intervention ]
Taste sensitivity is measured by five taste solutions（salty、sour、bitter、sweet、umami). Every taste solution contains 8 different concentration. Detection , recognition and difference thresholds will be measured .Their definitions are as bellow.
Detection threshold：minimum value of sensory stimulus needed to give rise to a sensation. The sensation need not be identified.
Recognition threshold：minimum value of a sensory stimulus permitting identification of the sensation perceived.
Difference threshold：value of the smallest perceptible difference in the physical intensity of a stimulus.
