一盘香椿炒鸡蛋引发大抢救!专家:哪些食物需要淖水

2021-04-07 见微知远 三甲传真

去年的4月出现一个这样的新闻报道,重庆75岁的余老先生突然出现发抖、发冷症状,同时上吐下泻,紧急送医后,被当地医院诊断为食物中毒引发肝脏、肾脏等多器官衰竭,经转院住进ICU(重症监护室)观察,险些丢掉

去年的4月出现一个这样的新闻报道,重庆75岁的余老先生突然出现发抖、发冷症状,同时上吐下泻,紧急送医后,被当地医院诊断为食物中毒引发肝脏、肾脏等多器官衰竭,经转院住进ICU(重症监护室)观察,险些丢掉性命。而“罪魁祸首”竟是一盘香椿炒蛋……

原来前日晚餐时,家人在香椿树上摘了半斤香椿芽,全部炒了蛋。余老先生觉得香椿炒蛋特别好吃,一口气吃掉了五分之四。

医生表示,香椿芽营养丰富,但同时也易富集土壤中的硝酸盐,转化成亚硝酸盐。亚硝酸盐能与人体血红蛋白结合引起高铁血红蛋白症,严重可危及生命。

正因为香椿芽含有很重的亚硝酸盐,一旦吃得不合适,就容易出现亚硝酸盐中毒。

但是,我个人觉得这个病例可能并不是亚硝酸盐中毒,因为量的问题,大概一次食用2斤以上才可能达到,上述病例我觉得不除外过敏,但是提醒大家应该注意,好吃别吃太多!

安全吃香椿做好这两点

其实香椿只要处理得当,正常食用,其产生风险非常低。

1 吃前焯水。

焯烫是降低亚硝酸盐最佳方法之一,研究表明,焯烫1分钟,可除去2/3以上的亚硝酸盐和硝酸盐。

2 最好只吃香椿嫩芽。

不同时期香椿所含硝酸盐和亚硝酸盐含量不同,发芽期,香椿的硝酸盐和亚硝酸盐含量是最低的,随着时间的推移,两者的含量会逐渐上升。

这些菜吃之前也要焯水

1、木耳:焯水能去毒

买木耳,一般都是干木耳,泡发后、食用前最好用热水焯熟,时间不宜太久。

鲜木耳含有一种卟啉物质,进入人体后,在光线照射下易损伤细胞或引起炎症等。虽然木耳干制过程中大部分卟啉会分解,但在食用前最好先用水浸泡几小时或用热水焯一下,以减少剩余毒素。

2、菠菜:焯水能去除草酸

菠菜吃起来有涩涩的感觉,是因为其中含有大量草酸。草酸含量高,不但影响口感,还会影响钙、镁、铁等矿物质的吸收。

吃菠菜前最好用沸水焯一分钟,可去除大部分草酸,凉拌或下到锅里煮汤,口感和营养都得到提升。另外,苋菜、茭白及马齿苋等野菜中草酸含量也较高,食用时要注意。

3、芥菜:焯水减轻异味

芥菜吃起来有“异味”,很多人不喜欢。芥菜有一种辛辣的芳香气味,对鼻腔有刺激作用,对眼睛也有催泪作用。

其实,把芥菜放入沸水焯一下,水要多、沸腾状态下快进快出,即可减轻其强烈刺激气味。也可以急火快炒,从而减轻“异味”。

4、四季豆:焯水防中毒

未炒熟的四季豆中含有皂甙,人食用后会中毒。鲜扁豆中含有皂甙和生物碱,有毒,但遇热后会溶解。食用这类食物前,最好用沸水焯透或过油,炒至变色后食用。

5、西兰花:焯水更干净

西兰花是一种非常美味的食材,不可否认西兰花里面容易藏匿一些小虫子,怎么清洗很重要。

西兰花先用清水洗2~3遍,再浸泡15~20分钟,可以有效祛除虫子和农药。还有一种方式就是焯水,更加有利于西兰花的烹制,所以不妨在清洗西兰花之后再焯水。

经过高温,小虫子基本会被杀死,注意焯水时间不宜过长。为了保证西兰花清脆的口感,焯水之后要用凉水过一下水。

6、鲜黄花菜:焯水防中毒

不主张大家吃新鲜的黄花菜,因为鲜黄花菜中含有秋水仙碱,它本身没有毒,但是经肠道吸收后在体内就转变成有毒的二秋水仙碱了,对胃肠黏膜和呼吸器官黏膜有强烈的刺激作用,会引起头痛、口渴、呕吐、腹泻等症状。

鲜黄花菜如果处理得当,也可食用。因为秋水仙碱溶于水,烹炒前用开水焯烫,或者进行泡煮,会减少其在蔬菜中的含量,降低对人体的毒性。可一旦处理不好,食用后就有中毒风险,还是尽量少吃为妙。干黄花菜中不含有秋水仙碱,可以放心食用。
