Int J Food Sci Nutr:钠摄入量并不能调节经常饮用咖啡对血压的影响

2020-06-24 MedSci原创 MedSci原创

钠的摄入量会因血压升高而增加心血管疾病的风险。咖啡的摄入会急剧升高血压。临床前证据表明,高盐摄入量可增强咖啡因的这种作用。我们假设高钠摄入量会增加人类对咖啡的急性血压反应。

钠的摄入量会因血压升高而增加血管疾病的风险。咖啡的摄入会急剧升高血压。临床前证据表明,高盐摄入量可增强咖啡因的这种作用。我们假设高钠摄入量会增加人类对咖啡的急性血压反应。

 

研究人员进行了一项随机交叉研究(n = 15),比较了低咖啡​​摄入量(6 g / d; LS)和高氯化钠饮食(12 g / d; HS)对正常咖啡摄入前后血压的影响(n = 15) 。

 

结果显示,LS期间基线血压为115±4/84±2/68±1,HS期间基线血压为121±4/89±2/69±1 mmHg(SBP /平均动脉压(MAP)/ DBP;平均值±SE,p < SBP为0.05)。在LS期间,血压升高至121±4/91±2/73±1(SBP,MAP,DBP与基线相比,p <0.05)。 HS并未显着影响咖啡对血压的影响(对于SBP,DBP,p> 0.3;对于MAP,p> 0.05)。

 

综上所述,该研究结果表明,钠摄入量并不能适当地调节经常饮用咖啡对血压的影响。
