The classification of dietary fiber, what are the dietary fibers

1. Soluble fiber.

Soluble in water, it becomes a gelatinous semi-fluid after absorbing water, and is easy to ferment under the action of bacteria in the colon to produce gas and physiological active by-products, which is a prebiotic.

Some soluble fibers prevent intestinal mucosal adhesions from translocation and thus regulate intestinal inflammation, an effect called contrabiotic.

2. Insoluble fiber.

Insoluble in water, it is metabolically inert, provides bulking, and can be non-fermented, such as lignin.

Able to change the absorption rate of soluble dietary fiber; It can also be made of prebiotics and fermented in the large intestine, such as resistant starch.

Filler fibers absorb water as it passes through the digestive tract and promote bowel movements.

Classification: Dietary fiber is a carbohydrate that cannot be digested by the human body, and can be divided into two basic types in order to be dissolved in water: water-soluble fiber and insoluble fiber.

Cellulose, partial hemicellulose and lignin are three common insoluble fibers that are found in plant cell walls. Pectin and gum are water-soluble fibers that exist in non-fibrous substances in nature. Common foods such as barley, beans, carrots, citrus, flax, oats, and oat bran are rich in water-soluble fiber, which slows digestion and excretes cholesterol the fastest, helps regulate immune system function, and promotes the excretion of toxic heavy metals from the body. Therefore, it can control blood sugar and cholesterol at the ideal level, and can also help diabetic patients improve insulin levels and triglycerides.

Insoluble fibers include cellulose, lignin, and some hemicellulose as well as wheat bran, corn bran, celery, fruit peels, and root vegetables from food. Insoluble fibre can reduce the risk of bowel cancer, prevent constipation and diverticulitis by absorbing toxic substances from food, and reduce the excretion of toxins by bacteria in the digestive tract. Most plants contain both water-soluble and insoluble fiber, so eating a balanced diet with water-soluble and insoluble fiber can provide different benefits.

Some specific deep-sea red algae plants contain both water-soluble and insoluble dietary fiber, such as the cold day powder in orange cold days, which contains as much dietary fiber. Water-soluble fibers and non-repermissible fibers each account for 50%. It can be said to be the richest in dietary fiber.

Dietary fiber is divided into soluble dietary fiber, good fiber, and insoluble dietary fiber. 1. Soluble dietary fiber: **Zen belt is empty in pectin, algin, konjac, etc.

Konjac is abundant in Sichuan and other places in China, and the main component is glucomannan which is a soluble dietary fiber with low energy and strong water absorption. 2. Insoluble dietary fiber: The best** is whole grains, including wheat bran, cereals, whole wheat flour and brown rice, oats whole grains, legumes, vegetables and fruits.

Dietary fiber is divided into soluble dietary fiber and insoluble dietary fiber.

1. Soluble dietary fiber: ** in pectin, algin, konjac, etc. Konjac is abundant in Sichuan and other places in China, and the main ingredient is glucomannan which is a soluble dietary fiber with low energy and strong water absorption.

Dietary fiber is divided into soluble dietary fiber and insoluble dietary fiber.

1. Soluble dietary fiber: ** in pectin, algin, konjac, etc. Konjac is abundant in Sichuan and other places in China, the main ingredient is glucomannan , which is a soluble dietary fiber sold clearly, with very low energy and strong water absorption.

With the in-depth development of nutrition and related science, people have gradually discovered that dietary fiber has a very important physiological role. As a result, today's dietary composition is becoming more and more refined, dietary fiber has become a substance of concern to the academic community and the general public, and has been supplemented and recognized as the seventh category of nutrients by the nutrition community, alongside the traditional six types of nutrients - protein, fat, carbohydrates, vitamins, minerals and water. Whole grains have a lower carbohydrate content than fine grains and a higher dietary fiber content, which makes them more likely to feel full after eating, which can reduce calorie intake.

However, you can't only eat coarse grains for a long time, which will cause malnutrition, so pay attention to the appropriate amount. The Dietary Guidelines for Chinese Residents recommend that the daily intake of coarse grains and whole cereals per person should be 50-100g (accounting for 1 4 1 5 of the staple food). If the total amount of staple food eaten per day is 250g, then the coarse grain is about 50g.

What are the dietary fibersWhat is dietary fiber? Dietary fiber is a type of carbohydrate that cannot be digested by the human body, referring to cellulose, hemifiber lisin and lignin. Dietary fiber is found in plant cell walls, such as our common pectin and gum are very common dietary fibers in our lives.

So what are the rich dietary fibers? What are the benefits of dietary fiber for the human body? Let's take a closer look.

What are the dietary fibersDietary fiber is one of the essential foods in our lives, which not only has edible value, but also has strong medicinal value. So what are the benefits of intaking dietary fiber for the human body? Dietary fiber has a health effect on the prevention of cardiovascular diseases, diabetes and cancer.

Therefore, we can supplement dietary fiber appropriately in life. By eating dietary fiber, it can promote the decomposition of blood sugar and cholesterol, and has a significant effect on protecting the fragile digestive tract and preventing colon cancer.

What are the dietary fibers in life? There are many foods that contain dietary fiber in our lives, including carrots, soy products, wakame, corn, millet, barley, wheat husks, etc., these foods are also very common in our lives, belonging to the category of cereals, so don't eat fine on weekdays, you can eat more coarse grains.

Dietary fiber is in addition to protein, fat, carbohydrates, vitamins, minerals, water and other six nutrients needed by human beings to maintain life and healthy growth, and is recognized by the public as the "seventh major nutrient", so what is dietary fiber? What are the main effects of dietary fiber on the human body? Dietary fiber refers to the general term for polysaccharides, carbohydrates and lignin that are not digested by the human body.

According to its solubility, it can be divided into two categories: water-soluble dietary fiber (SDF) and water-insoluble dietary fiber (IDF). The main components of water-soluble dietary fiber are the storage substances and secretions in plant cells, and also include some microbial polysaccharides and synthetic polysaccharides. It generally has more branches in its structure, so that it has the ability to combine with harmful substances in the human intestine; At the same time, it can be degraded and utilized by some beneficial microorganisms as its own nutrients in the intestine.

The main components of water-insoluble dietary fiber are cellulose, hemicellulose, lignin, protopectin and chitosan, etc., which have a compact structure and cannot be utilized by intestinal microorganisms, and its role is mainly manifested in promoting intestinal peristalsis. The health functions of dietary fiber are as follows:1

Prevention of obesity, 2Prevention of hemorrhoids and constipation, 3Prevention of intestinal diseases, 4

Prevention of diabetes, 5Lowers cholesterol levels. Prevention of cardiovascular disease, 6

Prevent and treat high blood pressure. Thank you, in the next issue, we will introduce the specific efficacy and principle of dietary fiber one by one.

Dietary fiber is a polysaccharide that can neither be digested and absorbed by the gastrointestinal tract nor produce energy. As a result, it was once considered a "nutrient-free" substance and was not given enough attention for a long time.

However, with the in-depth development of nutrition and related sciences, people in Taizheng have gradually discovered that dietary fiber has a very important physiological role. As a result, as the composition of diets is becoming more and more refined, dietary fiber has become a substance of concern to the academic community and the general public, and has been supplemented and recognized as the seventh category of nutrients by the nutrition community, which is alongside the traditional six categories of nutrients - protein, fat, carbohydrates, vitamins, minerals and water.

The diet of our people is mainly cereals, supplemented by vegetables and fruits, so there is no risk of dietary fiber deficiency, but with the improvement of living standards, the degree of food refinement is getting higher and higher, and the proportion of animal food has increased greatly. In some large cities, the proportion of dietary fat produced by residents has increased from 20% to 25% decades ago to 40% and 45% of the current rolling beams, while the intake of dietary fiber has decreased significantly.
