原标题:

  时下正值鲜玉米大量上市,嫩嫩的玉米散发出甜甜的香味,十分诱人。大口大口地啃玉米特别过瘾,但有人吃时囫囵吞枣,吃完后玉米棒上留下了许多淡黄色的小芽。这些被浪费掉了的小芽其实是玉米最有营养的精华——玉米胚芽。

  玉米胚芽是玉米粒中营养价值最高的部位,是玉米生长和发育的起点。虽然它的重量仅占玉米粒的11%~14%,但其脂肪占总籽粒的84%,蛋白质占22%,矿物质占83%。大家所熟知的玉米胚芽油就是从玉米胚芽中提炼出来的。

  玉米胚芽富含油酸和亚油酸,对降血清胆固醇、抗氧化、提高免疫力有益。同时它也是脂溶性维生素E、卵磷脂和植物甾醇的宝库。玉米胚芽氨基酸种类齐全,含量相对平衡。玉米胚芽中还含有功能性因子γ氨基丁酸和谷胱甘肽,在改善脂质代谢、减缓动脉硬化、保肝护肝等方面效果显著。膳食纤维在玉米胚芽中占9%,它对保持肠道健康、缓解便秘、降低血糖等均有作用。

  因此,大家在吃玉米时应细嚼慢咽,把玉米粒嚼碎,胚芽啃干净,将营养统统吃进肚子里。
