对于想减肥或患有高血压的人来说,芋头真是绝佳食材
要说芋头的好处,其实大家可以与土豆、山药做类比,同样是块茎类的食材,芋头完美集合了土豆和山药的优点,当然还有缺点。
中医认为芋头有开胃生津、补气益肾的功效,这一点与山药很像。和山药更像的是,他们都含有黏液,这是一种可以使人过敏的黏液,但同时也是一种好东西,黏液主要成分是黏蛋白和甘露聚糖,是一种多糖蛋白质的混合物,好处是能提高机体免疫力。
芋头含有大量淀粉和膳食纤维的情况,又与土豆有的一拼,但不同的是,芋头所含的颗粒淀粉非常小,所以入口的感觉是细软,并绵甜香糯。此外,土豆含有龙葵素,生芽的土豆是不能食用的,而芋头发芽并没有毒素产生。
芋头的补中益气其实也得益于他所含的淀粉、黏液蛋白以及矿物质,所以特别适合身体虚弱者食用。但也由于它所含的淀粉太多,如果一次吃得过多,也会导致腹胀。
每100克芋头可食部中含热量79千卡,比香蕉的热量还要低很多。膳食纤维丰富,又几乎不含胆固醇和脂肪。块茎类的食物又容易产生饱腹感,像这样的食材,真是太适合想减肥的人食用了。
根据营养分析,芋头含有醣类、膳食纤维、维生素B群、钾、钙、锌等,其中以膳食纤维和钾含量最多。B族维生素含量较多,可以帮助身体代谢,但是维生素A和C含量较小,要注意从其他食物中补充。另外,高钾低钠的特点,也让芋头成为高血压病人的最佳天然食材。此外,芋头所含的矿物质中,氟的含量相对高一些,具有洁齿防龋的作用。
芋头应该煮熟了吃
①陶弘景:"生则有毒,莶不可食。"
②《千金食治》:"不可多食,动宿冷。"
③《本草衍义》:"多食滞气困脾。"
生芋头有小毒,所以一般人也不会生吃。但熟吃也不能吃太多,容易腹满胀痛。生吃有黏液对皮肤和喉咙等均有刺激,但这些黏液一旦遇热,就被破坏结构了,煮熟之后则一般不再会使人过敏了。
贮存方法
在我们老家那,一般都是放在地窖中的,地窖中冬暖夏凉,这种存放方式一般不太容易坏。城市里没有地窖,大多人会选择放进冰箱,其实这种方式反而更容易坏,因为芋头不耐低温,容易冻伤,腐烂的更快。不如放在家里北侧阴凉通风处比较好。
