高盐摄入是高血压的主要危险因素之一,并与心血管事件密切有关。


目前,大多数国家的饮食习惯表现出传统的高盐摄入量;因此,在人群层面确定减少盐摄入量的最佳策略可能会对公共健康产生重大影响。

近期,一项发表在杂志Hypertension上的多中心随机双盲观察和介入研究中,偏好较高调味品的受试者的盐摄入量和血压低于不喜欢辛辣食物的受试者。

辛辣味的味觉享受增强了受试者对盐的敏感性并降低了对盐的偏好。

盐的摄入和盐的偏好习惯与受试者的脑岛和眶额叶皮层(OFC)区域代谢活动有关。给予辣椒素(辣椒的主要辣味成分)增强了脑岛和OFC对高盐刺激的代谢活性,这逆转了在脑岛和OFC代谢中盐浓度依赖性差异。

在动物研究中,OFC的活动与盐的偏好密切相关,并且在辣椒素的存在下,OFC中处理的咸味信息受到影响。因此,与该区域有关的干预措施可能会通过纤维荧光测定法和光遗传学技术改变小鼠对盐的偏好。

综上所述,享受辛辣食物可以通过改变脑中咸味的神经处理来显着降低个人对盐的偏好、每日食盐摄入和血压。辛辣味的应用可能是一个具有前景的行为干预,以降低人群高盐摄入量和血压。
