网传樱桃核有剧毒嚼碎会致命 专家:中毒概率低

2016-05-23 08:45:13   中国广播网

吴教授说,很多蔷薇科植物的果核里都有“氰苷”,如桃、杏、李子等,樱桃核小,含量更低。“氰苷”本身不会让人中毒,要接触胃酸,才会转化成氢氰酸,该物质也要达到一定量,才会引起急性中毒。

他介绍,每克樱桃核仁中的“氰苷”,折算为氢氰酸后大约只有几十微克,而氢氰酸导致人中毒的剂量,约为每公斤体重摄取2毫克左右(1毫克等于1000微克)。假设每克樱桃核仁能“产生”50微克氢氰酸,一名体重60公斤的成人吃下4.8斤樱桃核仁,才会出现中毒症状,“嚼5颗就毒晕一个成年人”的说法显然有些夸大。

医院:无中毒病例但需防儿童果核卡喉

记者昨日走访了福州各大医院。据了解,各医院均没有接到过“吃樱桃致氰中毒”的病例。省急救中心一位有多年急性中毒诊疗经验的负责人也表示,未遇到过嚼碎樱桃核而中毒的病人。

不过,协和医院急诊一名医护人员提醒,在樱桃大量上市的季节,常有人因樱桃吃得太多,导致肠胃负担过重,引发消化不良,建议控制食量。另有医护人员提醒,儿童食用樱桃、瓜子等,可能出现“果核卡喉”的情况,建议家长用筷子去除果核,防止果核卡在孩子气管中,引发窒息。
