Classification and function

According to whether it is soluble in water, dietary fiber can be divided into two categories:

Dietary fiber = soluble dietary fiber+insoluble dietary fiber, "soluble and insoluble, with different functions".

1. Soluble dietary fiber

Derived from pectin, alginate, konjac, etc. Amorphophallus konjac is abundant in China, Sichuan and other places. Its main component is glucomannan, which is a soluble dietary fiber with low energy and strong water absorption.

Many studies have shown that konjac has the functions of lowering blood fat and blood sugar, and has a good laxative effect; Soluble fiber interweaves with carbohydrates such as starch in gastrointestinal tract, delaying the absorption of the latter, so it can reduce postprandial blood sugar;

2. Insoluble dietary fiber

The best sources are whole grains, including wheat bran, oatmeal, whole wheat flour and brown rice, oatmeal whole grains, beans, vegetables and fruits.

The effect of insoluble fiber on human body is to promote gastrointestinal peristalsis, accelerate the speed of food passing through gastrointestinal tract and reduce absorption. In addition, insoluble fiber absorbs water in the large intestine and softens stool, which can prevent constipation.

Our people's diet is mainly cereal, supplemented by vegetables and fruits, and they are not afraid of the lack of dietary fiber. However, with the improvement of living standards, the degree of food refinement is getting higher and higher, and the proportion of animal food is greatly increased.

The heat production ratio of dietary fat in some big cities has increased from 20% ~ 25% several decades ago to 40% ~ 45% at present, while the intake of dietary fiber has obviously decreased. The so-called "life is getting better and better, and there is less and less fiber".

As a result, some so-called "modern civilization diseases", such as obesity, diabetes, hyperlipidemia and so on. And some diseases related to too little dietary fiber, such as intestinal cancer, constipation, intestinal polyps and so on. , are increasing.
