2两螃蟹胆固醇等同5两肥肉?健康吃蟹听医生怎么说

2017-09-28 16:02:52   

传言三:孕妇和儿童不能吃螃蟹

家有小孩和老人的会很担心:“是不是老人和孩子不能吃螃蟹,否则容易拉肚子?”

专家解读:中医讲,河蟹具有活血、促进骨骼发育的功效,尤其是蟹爪,经常被应用在接骨药中。不建议老人吃蟹的原因,还是因为螃蟹自身寒凉,而老人的脾胃偏弱,食用后易出现胃胀、腹泻的情况。而2岁以内的孩子,小肠功能发育得并不完善,不能很好地消化吸收螃蟹中的蛋白质,一旦身体过度“防御”,就会出现特异蛋白过敏现象,所以两岁以内的孩子吃螃蟹应慎之又慎。

虽说传言虚虚实实,不可全信,但浙江省新华医院的医生提醒,不同的人的确要根据自己的实际情况来吃蟹,有些人甚至不适合食用螃蟹。

1.吃蟹加些新鲜姜末和食醋

螃蟹味咸、性寒,而生姜性温,具有温中散寒解毒之功效;醋除了调味外,还可以杀菌,破坏蟹中的组胺。而且生姜和食醋是调味品,吃蟹时蘸上姜末醋汁,才能使蟹味更鲜美。

2.不吃死蟹

蟹死后,其僵硬期和自溶期大大缩短。蟹体内的细菌会迅速繁殖,并扩散到蟹肉中去。在弱酸条件下,细菌会分解蟹体内的氨基酸,产生大量组氨和类组氨物质。组氨会引起过敏性食物中毒,类组氨会使食者呕吐、腹痛、腹泻。

3.吃蟹要适量,搭配有讲究

吃蟹时和吃蟹后1小时内不要喝茶。因为开水会冲淡胃酸,茶会使蟹的某些成分凝固,不利于消化吸收,还可能引起腹痛、腹泻。

4.以下人群不宜吃蟹

患有伤风、发热胃痛以及腹泻的病人,消化道炎症或溃疡胆囊炎、胆结石症、肝炎活动期的人都不宜食蟹。

患有冠心病、高血压、动脉硬化、高血脂的人应少吃或不吃蟹黄,蟹肉不宜多吃。

过敏体质的人不宜吃蟹。

5.吃蟹不宜乱嚼一气

吃蟹时,在开盖后要注意四个清除:清除蟹胃,就是蟹盖里三角形的骨质小包,先吃蟹盖部分,用小勺把中间的蟹胃部分舀出,轻轻将外面包裹着的蟹黄吮干净。注意,不要吮破中间那个呈三角锥状的蟹胃,内有污沙应将其丢弃;吃完蟹盖轮到蟹身,先用剪刀将多余的蟹脚、蟹嘴剪掉;用勺柄将蟹身中间一个呈六角形的片状物挑出来,那是蟹心部分应丢弃。还有蟹肠,即由蟹胃通到蟹脐的一条黑线;蟹鳃,即长在蟹腹部如眉毛状的两排软绵绵的东西,都应该清除掉。
