When dietary fiber enters the human body, the fiber element will quickly dissolve in various parts of the human body. Dietary fiber has been widely valued by people in various fields due to its characteristics of solubility, elemental balance and richness. When formulating and designing typical formula foods for special medical purposes, the correct use of dietary fiber components is mainly reflected in the following points.

1. Enhance the protection of human intestinal barrier.

The human intestinal tract itself belongs to the absorption system and digestive system. Its basic function is to absorb and transform external nutrients, and convert various external substances ingested by the human body into essential nutritional elements for the human body. At the same time, the human intestine also has the function of isolating harmful bacteria, which can be filtered out through the intestinal filtration system and excluded from the absorption range of the human body. Once the protective barrier of the human intestinal tract is damaged, harmful bacteria may invade other organs of the human body, causing organ lesions, and even causing cancer of human organs.

Incorporating dietary fiber into special-purpose foods can help the human body repair the damaged intestinal protective barrier, which is of non-negligible significance for enhancing intestinal protection. For example, in the preparation process of enteral nutrition preparations, the key point is to choose the type of dietary fiber reasonably. It can combine the time interval of the human intestinal tract to produce feces, the length of intestinal operation and the properties of feces to select the type and ratio of dietary fiber that is suitable for the patient's body function, so as to fundamentally improve the protective function and digestion and absorption function of the human intestinal tract.

2. Closely combine the physiological characteristics and age structure characteristics of specific groups of people.

In view of the rapidly degraded excretory and absorption functions of the aging population, it is urgent to repair the human organ system by taking dietary fiber to improve and regulate human function. In addition, special populations during pregnancy and lactation should also consume a specific proportion of dietary fiber elements to fully meet the physiological function needs of pregnant and lactating women.

If the human body wants to maintain a healthy physiological state, it must rely on sufficient prebiotics as a guarantee, and fructooligosaccharide is a typical prebiotic. If the human intestinal tract can be evenly covered with fructooligosaccharides, it is beneficial to the reproduction of bifidobacteria and has a significant inhibitory effect on harmful bacteria. It can be seen that the microecology in the intestinal system should be optimized and improved in an all-round way to ensure a more balanced and healthy operation of the human digestive tract. When fructooligosaccharides are integrated into the human intestinal tract, it is beneficial to reduce the body's cholesterol and blood lipid levels, and the metabolism of lipids ingested by the human body will also be accelerated.

In the in-depth research and development and exploration of formula food in the future, it is necessary for technicians to focus on groups of special ages and special physiological periods. Through the in-depth development of the above-mentioned formula foods, technicians should be able to ensure that people in special physiological periods have more balanced nutritional elements and promote the improvement of human immune function and resistance.

3. Ensure the balance of dietary nutrients.

Although some patients with organ dysfunction have taken dietary fiber, they have not paid enough attention to the balanced collocation and intake of dietary fiber, resulting in severe organ dysfunction. It can be judged from this that a balanced intake of various types of dietary nutrition is of key significance for maintaining human health.

Since the end of the 20th century, many scholars have focused on conducting clinical trials on animals. Through animal experiments, technicians found that nutrients outside the intestines can cultivate lymph node bacteria, but foods with high dietary fiber content such as corn can hinder the movement of bacteria, so objectively achieve the comprehensive repair function of the intestinal protective barrier. If fiber elements can be properly added to the daily food intake of patients, it will be very helpful for a balanced diet and maintain the normal number of intestinal flora for a long time. Under the action of cellulose, the human intestinal mucosa can maintain normal and stable operation, which can effectively prevent atrophic intestinal diseases.

A balanced diet should be regarded as the primary factor in ensuring human health. In the absence of balanced dietary nutrients, the probability of various diseases will increase significantly. The practical application of dietary fiber can profoundly reflect the good practice effect of promoting physical fitness, and fundamentally improve and adjust the single dietary intake structure. Only by properly controlling the proportion and total amount of dietary fiber ingested by the human body can symptoms such as gastrointestinal discomfort be avoided, and at the same time, essential nutrients can be supplemented for various functional organs of the human body.

Dietary fiber, as the most basic element component, is indispensable in formula foods for special medical purposes. Special populations suffering from certain organ diseases cannot normally take in balanced dietary nutrients due to organ dysfunction. Only by taking formula foods for special medical purposes can they maintain a balanced diet. On this basis, the process of optimizing the design of food formula must fully consider the combination and matching of dietary fiber, enhance the ability of special populations to absorb various dietary nutrients, and effectively promote the health of special populations.
