白菜是不是只能竖着切,否则会把纤维切断,妨碍它的营养作用?是不是去掉菜筋就没有纤维了?有筋的菜是不是纤维含量最高?纤维是不是越长越有用?说实话,这些问题挺让人无奈的,因为实在不靠谱。不过,既然问题已经提出来了,不妨就谈谈有关纤维的几个常见的不正确说法。只有蔬菜的筋里面才有纤维?错。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,必然会获得纤维。蔬菜筋并非蔬菜中纤维的唯一来源,而没有筋的食物很可能纤维含量更高。比 Cabbage is not only vertical cut, otherwise it will cut off the fiber, hinder its nutritional role? Is not to remove the fiber without the fiber? The fiber is the fiber content is the highest fiber is not the longer the more useful? To tell you the truth, these questions are quite helpless, because they really do not fly. However, since the problem has been raised, we might as well talk about several common incorrect statement about the fiber. Only vegetable ribs inside the fiber? Wrong. 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, will inevitably get fiber. Vegetable tendons are not the only source of fiber in vegetables, while those without tendons are more likely to have higher fiber content. ratio
