龙虾是很多人夏季爱吃的美食,看起来红彤彤的让人非常有食欲,而且肉质嫩滑爽口,十分的美味,小龙虾好吃,不过近日有营养师说,吃一顿大约2斤的小龙虾的热量非常高,相当于要跑半程马拉松才能消耗掉那些热量,建议一次吃最好不要超过十只。

1、吃一顿小龙虾的热量

最近,小龙虾陆续"爬上"各大餐馆的菜单,吃小龙虾喝啤酒成了吃货们的夜宵标配。有营养师表示,一顿麻辣小龙虾2斤的热量,可能需要跑步超2小时、走路5小时才能消耗掉,而这相当于跑了一个半程马拉松。不过有些吃货表示:道理我都懂,胖就胖吧

2、吃小龙虾的注意事项

吃虾后不宜服维生素C片剂

美国芝加哥大学研究人员通过实验发现,虾等贝壳类食物中,含有一种浓度较高的“五价砷化合物”。该物质吃下去本身对人体无毒害作用,但在服用维生素C片剂后,可使原来无毒的砷化物转为为有毒的三氧化二砷,即砒霜,能危及人的生命。

虾头和虾线千万不要吃

“小龙虾的虾头部分千万不能食用。”专家提醒,小龙虾的头部是吸收并处理毒素最多的地方,也是最易积聚病原菌和寄生虫的部分。

很多人在吃龙虾时喜欢食用虾头,尤其是虾头里的虾黄,但是小龙虾的头部是吸收并处理毒素最多的地方,也是最易积聚病原菌和寄生虫的部分,鉴于大部分饭店为了省事出售的小龙虾基本不除去虾头,所以在饭店食用龙虾的时候千万不要食用虾头;而虾线作为龙虾体内仅次于头部第二脏的部位,很多饭店也是为了省事并没有去除虾线,因此建议大家在吃龙虾前一定要把虾线去除。

肉体松软无弹性极有可能是死虾

买小龙虾最怕遇到死虾,因为小龙虾死后腐坏得很快,会分解产生组胺等有毒物质,滋生有害病菌,食用后容易导致腹泻等肠胃道感染性疾病,危害身体健康。烹调加工后的小龙虾端上来后,如果有浓烈腥味、虾体散开发直、肉体松软无弹性、颜色变深、壳身有较多黏性物质等现象,那么就极有可能是死虾制作的。

烹制前龙虾要放清水喂养24小时

在家烹制小龙虾时,一定要高温煮熟煮透,可通过观察虾仁横截面颜色是否一致来判断是否煮熟。建议在烹饪加工前,一定要放清水喂养24小时左右,这样,龙虾可以吐出体内的代谢物。另外,由于龙虾的生存能力极强,往往一些龙虾是从小水沟里打捞上来的,所以一定要用刷子将龙虾好好清洗,同时龙虾体内隐藏了大量泥沙和细菌的虾线也必须剔除干净,再用清水充分地清洗2-3次就基本可以下锅烹制了。

龙虾好吃但不可多吃

吃龙虾时,不要一次食用过多,因为龙虾是高蛋白食物,部分过敏体质者会对小龙虾产生过敏症状,如身上起红点、起疙瘩等等,最好不要食用小龙虾。同时,小龙虾是含嘌呤较高的水产品,而高嘌呤易形成高尿酸,从而导致痛风的发作,所以痛风病人也最好不要食用龙虾。

虾死亡时间越长积累的毒素越多

虾内含丰富的组胺酸,这是令其味鲜的主要成分。但虾一旦死亡,组胺酸即被细菌分解成为对人体有害的组胺物质。还有,虾的肠中常含有致病菌和有毒物质,死后体内极易腐败变质。特别是随着虾死亡时间的延长,虾体内积累的毒素更多,吃了便会出现中毒现象。

3、哪些人不适合吃虾

(1)过敏体质者

如上所说,龙虾可致敏,可诱发过敏性鼻炎、过敏性皮炎患者发病,所以过敏体质者是不宜吃的。

(2)患呼吸道疾病者

对于支气管炎、哮喘患者也是不易吃龙虾的,无论是支气管还是哮喘都是一种过敏性疾病,当人体受到过敏饮食刺激时,便会引起支气管痉挛,粘膜肿胀,分泌物增加,从而导致管腔狭窄,气道不畅,呼吸困难,从而诱发支气管炎和哮喘。

(3)皮肤病患者

龙虾为发风之物,可使人阳气升发,虚火内扰,助生外丹内毒,可诱发皮肤类疾病,所以皮肤病人是不宜吃龙虾的。

(4)吃中药者

龙虾为发物,可与中药发生反应,轻者会削弱功效,重者可重的会和中药里的相关成分发生作用,危害身体健康。

小龙虾十分的美味,不少人喜欢吃麻辣口味的小龙虾,吃起来虽然辣,但是感觉很爽,一吃就停不下来了,不过大家要注意吃小龙虾也有一些需要注意的地方,小龙虾属于发物,有些人群是不适合食用的,为了身体健康,适当的吃最好,不要过量。
