“蔬菜皇后”葱头对身体的八大益处 | 2012-11-13 7:59:00

葱头又名洋葱,作为蔬菜已有5000余年的历史,洋葱含有丰富的钙、磷、铁、维生素B1、维生素C、胡萝卜素、尼克酸、前列腺素A、二烯丙基二硫化物及硫氨基酸等成分,其中的硫氨基酸具有降低血脂和血压的功效,前列腺素A具有扩张血管、降低血黏度、预防血栓的作用。洋葱还富含微量元素硒,能降低癌症的发生率。一般成年人每日生吃50-80克洋葱的保健作用十分显著,真不愧为蔬菜皇后

每天吃洋葱,结果发现洋葱里所含的化合物也能阻止血小板凝结,并加速血液凝块溶解。所以,当你享用高脂肪食物时,最好能搭配些许洋葱,将有助于抵销高脂肪食物引起的血液凝块;所以说牛排通常搭配洋葱一起吃,是很有道理的.洋葱做菜不但味道极佳,且营养丰富。其实洋葱属碱性食物,并含有糖、无机盐、锌、硒(抗癌物质)、磷、硫等。

常吃洋葱对身体有以下益处:

1、所含前列腺素A是种较强的血管扩张剂,可对抗儿茶酚胺等升压物质,促进钠盐排泄,有降血压作用;

2、所含硫化物能促进脂肪代谢,具有降血脂、抗动脉硬化作用,若每天食用50-70克洋葱,其降血脂作用比服降脂药安妥明还强;

3、洋葱所含类黄酮能降低血小板的粘滞性,常吃洋葱可预防血栓,减少心梗和脑血栓概率;

4、洋葱含有与降糖药甲磺丁脲相似的有机物,能明显降低血糖含量;

5、所含硫化物、微量元素硒等,能抑制胃癌、食道癌、结肠癌、乳腺癌等;

6、洋葱所含挥发油能助性,老人常吃洋葱可提高性生活质量;

7、洋葱可提高实验鼠的骨密度,常吃洋葱可预防骨质疏松;

8、洋葱富含维生素C、尼克酸,它们能促进细胞间质的形成和损伤细胞的修复,使皮肤光洁、红润而富有弹性,具美容作用。所含硫质、维生素E等,能阻止不饱和脂肪酸生成脂褐质色素,可预防老年斑。另外,洋葱含抗菌、抗炎物质,吃洋葱可防治肠炎痢疾。

    章仁根相关知识:
      洋葱,为2年生草本植物。有关洋葱的原产地说法很多,但多数认为洋葱产于亚洲西南部中亚西亚、小亚西亚的伊朗、阿富汗的高原地区。洋葱的起源已有5000多年历史,公元前1000年传到埃及,后传到地中海地区,16世纪传入美国,17世纪传到日本,20世纪初传入我国。 洋葱在我国分布很广,南北各地均有栽培,而且种植面积还在不断扩大,是目前我国主栽蔬菜之一。我国已成为洋葱生产量较大的4个国家(中国、印度、美国、日本)之一。 我国的种植区域主要是山东、甘肃、内蒙古、新疆等地。
