is smaller than that of a lecture. When it comes to the physiological function of dietary fiber in relieving constipation, one student raised his hand and asked, “teacher, why did I have constipation after eating dietary fiber powder?” When her voice just fell, less than is really a little confused, but it is less than the teacher’s quick thinking, immediately understand the reason. It is this story that leads us to today’s topic: is the more dietary fiber the better? Generally speaking,

generally speaking, when nutritionists tell us to eat more vegetables and fruits to supplement dietary fiber, there is a big premise, that is, the lifestyle of modern people is not healthy, which is reflected in: excessive intake of animal food, the proportion of refined rice and flour is too large, these problems will lead to constipation symptoms. In this premise, eat more vegetables and fruits to properly supplement dietary fiber can improve the symptoms of constipation. Because the mechanism of dietary fiber in the body is like this:

in the above figure, dietary fiber can absorb water and expand, so as to make the intestinal tract convenient.

This principle is just like “making noodles”. Proper flour + proper water = OK. When there is too much flour, the flour will not mix because it is too dry.

therefore, although we advocate the intake of dietary fiber, but try to eat it in the way of vegetables and fruits, because there is a lot of water in vegetables and fruits, which can avoid the occurrence of the above problems. However, if it is supplemented by supplements, if it is overdosed, it will have the opposite effect. So the more dietary fiber, the better.
