降压药+柚子会导致血压骤降吗?

今天有一个朋友微信给我转发了一篇文章《又一年轻的帅哥离世了,医生说致死原因竟然是……》,问我有根据吗,并重点求证其中的“降压药+柚子=血压骤降”的真伪。我一看又是这一类对医学一知半解的人写的文章,名为普及健康知识,事实上确造成健康恐慌。

我告诉我的朋友,文章的内容毫无根据,不要理他。可巧合的是,又有网友通过新浪微博向我求证降压药与柚子合用引起血压骤降的问题,看来,这些伪科普还真有点影响力,于是我不得不说。

这篇文章说,柚子中含有生物活性成分能促使药物迅速进入血压,等于加大药量。另外,柚子本身有降压功效,如与降压药同服,会使药物增加几倍到几十倍,引起头晕、恶心,比较危险。

1、目前市面上常用的降压药在消化道的吸收是相对稳定的,即使个别食物对此有一定的影响,但绝对不会“增加几倍到几十倍”,更不会引起血压骤降。文中的观点,没有任何科学依据,教科书中没有,科研论文中也没有,请发布者注明出处,让我们看看是什么最新的科研成果。

2、“可以促进药物吸收,本身有降压功效”,这种说法本身就是药物作用的描述。根据相关的法律,除了正规的药物之外,任何物质不能表述有治疗功效,否则是违法的。把柚子当做药物描写,本身就是非法的。如果按文章所言,柚子对控制血压有如此大功效的话,那还生产降压药做什么?

3、几乎所有的水果都含有大量的糖、水分、维生素C、B族维生素、钾离子和少量的蛋白质等营养物质,除了糖的成分与含量不同之外,这些水果本质上并没有特别大的区别。如果说吃柚子+降压药导致血压骤降,那吃别的水果呢?生活中服用降压药期间因吃水果导致血压骤降者发生率是多少?

4、饮食中高钠、低钾是导致高血压的重要原因,而防控高血压,首先要限制钠的摄入量,同时增加钾离子的摄入量。低钠高钾盐被广泛推广就是基于这个目的。柚子中钾离子的含量较高,几乎不含钠离子,所以对控制血压是有帮助的。但并不是说,大量食用柚子就能够降血压。

香蕉、葡萄、桔子、哈密瓜等水果中都含有大量的钾离子,除了空腹血糖>8.0mmol/L之外,医学界鼓励高血压患者多吃水果,以帮助控制血压。如果这篇文章广为流传的话,势必造成一定程度的恐慌,谁还敢吃降压药,或者食用水果?如此一来对血压的控制有害无益。
