红薯的营养价值
红薯块根中含有60%-80%的水分,10%-30%的淀粉,5%左右的糖分及少量蛋白质、油脂、纤维素、半纤维素、果胶、灰分等,若以2.5Kg鲜红薯折成0.5Kg粮食计算,其营养成分除脂肪外,蛋白质、碳水化合物等含量都比大米、面粉高,且红薯中蛋白质组成比较合理,必需氨基酸含量高,特别是粮谷类食品中比较缺乏的赖氨酸在红薯中含量较高。此外红薯中含有丰富的维生素(E、B1、B2、C),其淀粉也很容易被人体吸收。
红薯的药用价值
药性功效
红薯含有独特的生物类黄酮成分,能促使排便通畅,可有效抑制乳腺癌和结肠癌的发生;能提高消化器官的功能,滋补肝肾,也可以有效治疗肝炎和黄疸。
红薯蛋白质质量高,可弥补大米、白面中的营养缺失,经常食用可提高人体对主食中营养的利用率,使人身体健康、延年益寿。
红薯富含膳食纤维,具有阻止糖分转化脂肪的特殊功能;可以促进胃肠蠕动和防止便秘,用来治疗痔疮和肛裂等,对预防直肠癌和结肠癌也有一定作用。
红薯对人体器官黏膜有特殊的保护作用,可抑制胆固醇的沉积、保持血管弹性,防止肝肾中的结缔组织萎缩,防止胶原病的发生。![](https://img.alicdn.com/imgextra/i3/71536231/TB28ohLapXXXXbzXXXXXXXXXXXX_!!71536231.jpg)
