摘要
High sodium intake is one of the risk factors for the development of hypertension. According to 2007 Korean National Health and Nutrition Examination Survey, sodium intake of Korean was three times higher than adequate intake (1.5 g/day) recommended by Korean Dietary Reference Intakes. High sodium intake is related to high threshold and preference of salty taste. And zinc status is known to affect taste acuity. The hypothesis of this study is that zinc status is associated with salty taste acuity, preference, sodium intake and blood pressure. The subjects included in this study were 50 men and 41 women aged 20-29 y who did not smoke and not take supplements or medications regularly. Dietary intake data for 3 days were collected by 24-h recall for 1 day and dietary record for 2-days. Salty taste acuity and preference were determined by sensory test. Fasting serum concentration of zinc, height, weight, body composition and blood pressure data were collected. Salt taste preference in high zinc intake group ($\geq$ estimated average requirement, EAR; men-8.1 mg/day, women-7 mg/day) was higher than that in low zinc intake group (< EAR). Salty taste preference was inversely correlated with serum zinc concentration in people with low concentration of serum zinc (${\leqq}\;81\;{\mu}g/dL$)(r = -0.3520, p < 0.05). Diastolic blood pressure was higher in high sodium intake group than in low sodium intake group (p < 0.05), positively correlated with salty taste preference (r = 0.3866, p < 0.05) in subjects with daily zinc intake below the EAR. We conclude that low zinc status may be related to high salty taste preference and high blood pressure in Korean young adults.

高钠摄入的危险因素高血压的发展方向之一。据2007年韩国全国健康和营养调查，韩国的钠摄入量明显高于摄入足量（1.5克/天）推荐的韩国居民膳食营养素参考摄入量高出三倍。高钠的摄入量有关，高门槛和咸口味偏好。和锌状态已知会影响味道敏锐度。本研究的假设是，锌状态与咸味视力，偏好，钠摄入和血压有关。纳入本研究对象为50名男性和41岁的女性20-29Ÿ谁不吸烟，不采取补充剂或药物定期。膳食摄入数据3天，收集通过24小时的召回1天，饮食记录用于2天。味咸敏度和偏好是由感官检验。锌，身高，体重，身体组成和血压数据的空腹血清浓度被收集。在高锌摄入组盐味的喜好（$ \\ GEQ $估计平均需要量，EAR;男人-8.1毫克/天，女性7毫克/天）明显高于低锌摄入组（咸的口味偏好呈负相关血清锌浓度与人血清锌浓度低（$ {\\ leqq} \\ 81 \\ {\\亩}克/分升$）（R \x3d -0.3520，P舒张压较高，高钠摄入组相比，低钠盐摄入组（p05）在受试者每日锌摄入量的EAR下方。我们的结论是低锌状态可能与高咸味偏好和在韩国年轻成人高血压。
