自古以来,国人“天人合一”的思想无不在生活中每一个角度体现着。二十四节气的变化也在影响着百姓的衣、食、住、行。古人云:春吃花、夏吃叶、秋吃果、冬吃根。在秋冬季节,应季的根菜大量上市,这时的根菜既新鲜,价格又便宜,还耐储藏,因此秋冬季节是吃根菜的好时候。接下来让我们了解一下常见根菜的营养。
萝卜
俗话说:“冬吃萝卜夏吃姜,一年不用医生开药方”。在我国民间素有“小人参”之美称的萝卜,可说是秋冬季节的佳品之一。生吃不仅可助消化、增食欲,还可去油腻、消食顺气;若是与其他食品搭档做成菜肴,也有不同之功效。萝卜具特有的辣味,生食可助消化、健胃消食、增加食欲,吃肉类等油腻食物后,生吃萝卜可解腻爽口使脘腹舒坦;过食甘薯胃酸胀满烧心时,生吃萝卜或嚼咸萝卜可消食顺气。同时,生萝卜还能促进胆汁分泌,帮助消化脂肪。
山药
山药既是中药,也是美食,是大家熟悉的滋补珍品。研究证明,山药中的B族维生素的含量是大米的数倍,矿物质中钾含量极其丰富。更要紧的是,山药富含多种生物活性成分,包括山药多糖、黏液蛋白、皂甙、尿囊素、脱氢
雄酮等。研究发现,山药中的低聚糖具有很好的免疫增强作用。山药中的生物活性物质具有很好的抗衰老作用,可提高动物免疫细胞增殖能力,延缓胸腺衰老。
此外,山药对于糖尿病有辅助疗效,除了易产生饱腹感,有利于控制食量外,甘露聚糖还有改善糖代谢,提高胰岛素敏感性的功用。由于山药中淀粉含量较高,因此在食用山药时,最好能用山药代替一部分主食,也就是适当减少主食的量,尤其是糖尿病人,以免带来能量过剩的问

苤蓝
苤蓝又叫王蔓青、直莲、芥蓝头,是甘蓝的一种,学名叫球茎甘蓝。苤蓝是介于大头菜和包心菜之间的蔬菜,叶片光滑鲜嫩,茎膨大成球形,有明显的叶痕,外皮绿、白或紫色,春秋两季栽培。苤蓝可以拿来清炒也可以凉拌生食,记得我小时候,每年冬天,家里都会买些苤蓝回来,尤其是在以前食物匮乏的年代,冬季来一小盘苤蓝丝,清脆爽口,回味无穷。它的维生素C含量丰富,每100克高达41毫克,远高于苹果、梨、葡萄等水果,苤蓝中还含有大量的钾,对人体十分有益。
中医认为它性凉味甘辛,有宽胸、止痰、化咳、醒酒降火、清神明目的功效。榨其鲜汁服用,对胃病有治疗作用,长吃苤蓝还能促进胃与十二指肠溃疡的愈合。
