银杏好处虽多,但有小毒,不宜多食。尤其是果皮中含有“白果酸”等有毒物质,过多食用会损害中枢神经系统,引起中毒。吃时不光要剥去内皮,即使是熟银杏肉也别过量食用。白果即银杏果,微苦涩,偏温,有小毒,主要有润肺止咳化痰效果,还能补肝肾,涩精止带缩尿作用。没有煮熟吃可以每天4~5枚,不建议长期大量食用。以免发生不必要的损害。有祛痰、止咳、润肺、定喘等功效,但大量进食后可引起中毒。白果内含有氢氰酸毒素,毒性很强,遇热后毒性减小,故生食更易中毒。一般中毒剂量为10-50颗,中毒症状发生在进食白果后1-12小时。为预防白果中毒,不宜多吃更不宜生吃白果。
意见建议:银杏食用时,因有微毒,不宜多食。熟食每人一般15-30粒为宜,去心多吃无妨;生食6-10粒为宜。
冬天,银杏树叶发黄,风一吹满地都是叶子,很多人忙着采摘银杏果也就是白果,它药食两对身体好,不少人都喜欢。中医将银杏入药做成药物,食品加工场会用银杏制作食物。
更多的时候,你会拿起银杏将其外壳剥掉开始食用,而家人看到会说:银杏虽好但不宜多吃,吃多易伤身。这到底对不对呢?下面就介绍银杏,以及哪些人不适合吃银杏?
银杏的营养
银杏得到认可主要是营养丰富,其中包括:白果酸、白果醇、白果酚、脂肪、淀粉、蔗糖、还原糖、核蛋白、矿物质、纤维素、维生素E、核黄素、花青素、氨基酸等,可以说银杏的食疗价值超乎你的想象。
在中医看来,更加看重银杏的药用价值。药用银杏,早有记载,元朝时在《日用本草》对银杏果入药做了描述,《本草纲目》:银杏,入肺经、益脾气、定喘咳、缩小便。到了清朝,《本经逢源》:白果,降痰、清毒、杀虫。银杏性平、味甘、微涩、有小毒,入肺经、肾经,对身体调节、保健很有益处。
银杏营养丰富、药用价值很高,食用有哪些好处?
杀菌
吃银杏能吸收白果酸、白果酚,具有杀菌作用,抑制呼吸道感染,例如,把银杏泡水喝,帮助抑制细菌。
治疗咳嗽
在冬天咳嗽加重,吃一点银杏能缓解咳嗽,能不断收敛肺气、定喘咳。家中有咳嗽患者,可以让其食用。
除皱护肤
吃银杏还能吸收黄酮苷、黄酮醇,这些物质都是清除自由基的好手,能保护真皮细胞,促进血液循环,避免皮肤被氧化,出现皱纹,进而能除皱护肤。
不可否认,银杏营养丰富,吃银杏对身体好,但是,在食用时一定要特别注意,因为一不小心就可能有大麻烦。
生吃不好
吃银杏不少人喜欢,特别是生吃。但是为了健康最好不要这样做,生吃银杏会引起中毒,表现出恶心、腹痛、腹泻等,银杏中的氰苷、银杏酚、白果酸都有毒生吃下去会引起中毒。
不要多
食用的量也有规范、要求的,例如,成年人的话每次吃20颗,儿童小于5颗,三岁以下的孩子不建议食用,新闻中有关于儿童吃银杏中毒的报道,需要引起重视。
这些人不能吃
除了婴幼儿不宜食用外,在生活中孕妇也不要吃,身体容易过敏的人也不建议多吃银杏。
银杏营养丰富、功效大,但是要遵循食用方式,要是错误的食用可能有较大麻烦,需要大家多注意不宜吃多,同时注意食用的量,以免有更大危险。
银杏吃多了会出现中毒的情况,通常是指过量的服用或者服用了生银杏所导致。中毒多发生于年龄小的人,尤其是儿童易发生中毒
