“膳食纤维”这个词已经被越来越多的人所熟知,然而真正了解这种营养素的人并不多。疑问一:只有蔬菜的筋和口感粗糙的食物里才有纤维?纯属谣言。每个植物细胞都有细胞壁,而细胞壁的主要成分就是纤维素、半纤维素和果胶,它们都属于膳食纤维。所以,只要吃植物性的食品,必然得到纤维。此外,主食当中的纤维,也不仅仅是小麦麸皮那种口感粗糙的东西。豆类的纤维含量比粗粮还要高,而人们却并不感觉到刺口。 The term “dietary fiber” has become known to more and more people, but not many people actually know about it. One question: Only vegetables and tendons taste coarse food fiber? Purely a rumor. Each plant cell has a cell wall, and the major components of the cell wall are cellulose, hemicellulose and pectin, all of which are dietary fibers. So, as long as eating plant foods, inevitably get the fiber. In addition, the fiber in the staple food is not just the rough taste of wheat bran. The fiber content of legumes is even higher than coarse grains, but people do not feel the thorn.
