豇豆功效与作用及禁忌

豇豆的营养价值

豇豆,很多人都不了解是什么,其实豇豆就是我们常吃的长豆角,属于豆角的一种,食用方法多样,味道鲜嫩美味,深受吃货们的喜爱。那么我们常吃的豇豆有什么好处及食用禁忌呢?下面和小编一起去了解下吧!

豇豆功效与作用

1、补肾是豇豆的一个重要功能,对尿频、遗精和一些妇科功能性疾病有辅助疗效。历代医家把豇豆视为治疗肾虚梦遗、滑精的妙药。

2、豇豆可以健脾、和胃,积食、气胀或者打嗝的时候,取适量豇豆,细细咀嚼后咽下,具有很好的缓解作用。

3、豇豆连荚嚼食,可以让人体吸收数量丰富的膳食纤维,促进肠胃蠕动,从而帮助消化,并使大肠容易排泄,有通便的功能。因此,常吃豇豆能改善便秘。

4、豇豆中含有丰富的维生素C,维C能促进抗体的生成,提高人体对病毒的抵抗能力,增强机体的免疫功能。

5、豇豆的磷脂能够有效促进胰岛素分泌,参与糖代谢的作用,适宜糖尿病患者食用,有效降低血糖。

豇豆的禁忌

一次性吃豇豆太多会导致腹胀,所以不宜一次吃太多。感冒患者初期不能吃豇豆,因为初期患者饮食应该清淡一点,不宜厚重,这样才有利于病情好转、身体康复;豇豆忌不熟就吃,因为生豆角中的皂甙和凝集素两种有毒物质,经过高温可以被分解破坏,但如果豇豆半生不熟就会引起中毒。

豇豆的营养价值

豆角含有丰富的维生素B、和维生素C和植物蛋白质,能够使人头脑清晰,有调理消化系统、消除胸膈胀满、解渴健脾、补肾止泄、益气生津的功效。在夏天多吃一些豆角可以有效消暑,并起到青口的作用。

豆角所含B族维生素能维持正常的消化腺分泌和胃肠道蠕动的功能,抑制胆碱酶活性,可帮助消化,增进食欲。

豆角中所含的维生素C可以促进人体抗体的合成,可以提高人体的抗体病毒作用,还可以防止急性肠胃炎,呕吐腹泻。

豆角提供了易于消化吸收的优质蛋白质,适量的碳水化合物及多种维生素、微量元素等,可补充机体的招牌营养素。

挑选豇豆的方法

1、外表。外表有伤的,划痕的,或者斑点的,大家不要选择。应该挑选外表光滑,整齐的,有伤的豇豆会影响里面的味道,所以建议大家多挑选没有伤的。

2、颜色。刚成熟的豇豆是深绿色的,很嫩,而时间久了的豇豆会变黄,所以大家要多挑选颜色深而且绿的。如果豇豆上有黄色的部位,大家就不要挑选了。估计里面会很老。

3、长短。短的豇豆是老豇豆的可能比较大,所以建议大家挑选的时候挑较长的豇豆。一般的豇豆长度为45cm左右。大家可以按这个长短来选购。

4、粗细。过粗的豇豆应该是很老的了,过细的吃起来又没有什么味道。建议大家挑选的时候选择中等粗细的。好吃还健康。

5、豇豆顶部。就是秧上摘下来的部位,每个豇豆上头,都会有一个小帽。大家可以仔细观察,如果颜色是绿的,那么是新鲜的。如果已经变黄了的,建议大家不要挑选了。图片中的是时间久了

6、豇豆弦。大家可以当场掐一下豇豆的弦,如果很容易弦就下来了,并且还不是很粗的弦那么就是嫩豇豆了。时间久了一打手就会知道是不是老豇豆的。

如上所述,豇豆生活中非常常见的蔬菜之一,营养丰富,常吃可补充各位维生素及微量元素,对人体健康有很大的帮助。想要吃到新鲜美味的豇豆,挑选很重要哦!一定要注意挑选比较嫩的豇豆,口感也会更佳哦!
