又到了菠萝成熟的季节了,但是在广东东莞一果农,终止了四五十亩菠萝,成熟后却滞销,觉得拦在地里怪可惜的,于是在5月16日,这一果农家长,将4万斤菠萝送到儿子学校,送给孩子所在学校的老师和同学们免费品尝,而老师师生执意为菠萝“买单”,领取菠萝是自愿献出爱心,并且棒果农发起宣传。

送儿子学校4万斤菠萝,吃菠萝有哪些好处和禁忌?(1)

1、菠萝的功效作用

1.减肥

是不是也觉得新鲜,菠萝也可以减肥?千真万确。菠萝几乎含有所有的的人体所需的维生素,16种天然矿物质,并能有效帮助消化吸收。菠萝减肥的秘密在于它丰富的果汁,能有效地酸解脂肪,可以每天有效地在食物中搭配食用菠萝或饮用菠萝汁,但是切忌过量或食用未经处理的生菠萝,第一容易降低味觉,刺激口腔粘膜;第二,容易导致生产菠萝蛋白酶,对这种蛋白酶过敏的人,会出现皮肤发痒等症状。

2.清理肠胃

常常因为食用肉的含量多少而烦恼吗,菠萝可以帮助你解决消化吸收的顾虑。菠萝蛋白酶能有效分解食物中蛋白质,增加肠胃蠕动。

3.美容

丰富的维生素B能有效地滋养肌肤,防止皮肤干裂,滋润头发的光亮,同时也可以可以消除身体的紧张感和增强肌体的免疫力;其果肉可以作为面膜,是最香甜的护理用品;常常引用其新鲜的果汁能消除老人斑并降低老人斑的产生率。酶素可以降低血压,稀释血脂,食用菠萝,可以预防脂肪沉积。

4.消除感冒

发烧、咳嗽、嗓子疼都是感冒最明显的症状,除了趟在床上安静地休息,不妨饮用一杯新鲜的菠萝汁,它有降温的作用,并能有效地降低支气管。经医学研究,自古以来,人类就常常凭借菠萝中含有的菠萝蛋白酶来疏缓嗓子疼和咳嗽的症状。

5.消除水肿

溶解阻塞于组织中的纤维蛋白和血凝块,改善局部的血液循环,消除炎症和水肿

6.去油腻

清理肠胃:菠萝中所含的蛋白质分解酵素可以分解蛋白质及助消化

7.保健

促进血液循环酶,素来可以降低血压,稀释血脂

2、菠萝的选购技巧

一、看果实外观形态。

优质的菠萝,其果实呈圆柱形或两头稍尖的卵圆形,大小均匀适中,果形端正,芽眼数量少。成熟度好的菠萝表皮呈淡黄色或亮黄色,两端略带青绿色,上顶的冠芽呈青褐色;而生菠萝的外皮色泽铁青或略带褐色。如果菠萝的果实突顶部充实,果皮变黄,果肉变软,呈橙黄色,说明它已达到九成熟。这样的菠萝果汁多,糖分很高,而且香味浓郁,具有非常好的味道。如果不是立即食用,最好选果身尚硬,色泽为浅黄带有绿色光泽,约七八成熟的品种最好。

看外观颜色,通体金黄色的要比果身泛绿的要熟得透,味道也会甜一些

二、看果肉组织。

将菠萝切开以后,如果是果目浅而小,内部呈淡黄色,果肉厚而果芯细小的菠萝则为优质品;否则,果目深而多,内部组织空隙较大,果肉薄而果芯粗大为劣质菠萝。另外,未成熟菠萝的果肉脆硬且呈白色。

三、看果实的硬度。

挑选菠萝时,可用手轻轻的按压,如果发现菠萝坚硬而无弹性的是生菠萝。而挺实且微软的菠萝是成熟度好的优质菠萝。另外,过陷甚至凹陷者为成熟过度的菠萝。此外,如果发现挑选的菠萝(或放置一段时间的菠萝)有汁液溢出,则说明其果实已经发生变质,人们就不可以再食用了。

四、用鼻子闻。

可以用鼻子闻菠萝的香气是否浓郁,这样也可以判断出你挑选的菠萝是否成熟。一般成熟度好的菠萝外皮上能稍微闻到些香味,果肉则香气馥郁。而浓香扑鼻的菠萝为过熟果,时间放不长,且易腐烂。另外,无香气的菠萝则兴许是带生采摘果,所含糖分明显不足,吃起来也没什么味道。所以,挑选那种稍微能嗅到些香味的菠萝为佳。

3、菠萝的食用禁忌

1、由于菠萝中含有刺激作用的甙类物质和菠萝蛋白酶,它会分解体内的蛋白质,而且它对人们口腔粘膜和嘴唇的幼嫩表皮有刺激作用,如果吃菠萝前不用盐水泡,会让人有一种麻痹刺痛的感觉。

因此应将果皮和果刺修净,将果肉切成块状,在稀盐水或糖水中浸渍,浸出甙类,然后再吃。

用盐水泡菠萝后,能够有效破坏“菠萝朊酶”的内部导致过敏的结构,从而失去使人过敏的能力,并丧失对于有的体质的毒性。

2、在食肉类或油腻食物后,吃些菠萝对身体大有好处,“菠萝咕老肉”、“菠萝牛肉”都是可以放心吃的菜肴。

3、菠萝和鸡蛋不能一起吃,鸡蛋中的蛋白质与菠萝中的果酸结合,易使蛋白质凝固,影响消化。

4、菠萝加蜂蜜可以同时食用,而且菠萝加蜂蜜煎水服可治支气管炎。但是对于身体不适或腹泻症状的人建议不要这样食用。

菠萝虽然味道可口迷人,但是吃菠萝也是有禁忌要注意的,如果吃菠萝方式不当,也可能引起身体不适,而且菠萝一次性不能吃太多,更有部分过敏者禁止食用,因此在吃菠萝之前,需要先了解自己能否吃菠萝,适合吃菠萝的人适当吃对健康还是有不少好处的。
