What are fiber-rich compounds and why are they important for a healthy diet? They are high in sugar and belong to the carbohydrate group. They consist of, among other things, cellulose and pectin. These compounds are not digested by the body and cannot be used as an energy source. However, they play a crucial role and should be a regular part of the diet.

Nutritional Fiber: Classifications and Functions

Nutritional fibers can be classified into two primary categories: soluble and insoluble. Soluble fibers increase their volume upon exposure to water and function as a food source for gut bacteria. The loose stool mass, efficacy in treating diarrhea by forming high-viscosity gels, increased density of food content, and slowed digestion process in the gut are significant characteristics. Its ability to absorb heavy metal ions and bacterial toxins is substantial. It plays a crucial role in maintaining a healthy cholesterol level.

Sources of dietary fibers

In addition to soluble fibers, which include pectins, gums, mucilage, and inulin, there are also insoluble fibers, which include cellulose, lignin, and some hemicelluloses. This type of fiber provides a feeling of satiety, improves intestinal peristalsis, and reduces the risk of constipation. It also increases intestinal blood flow and the secretion of stomach juices. Insoluble fibers have anticarcinogenic properties, which are possible due to the increased stool volume and shortened transit time. This also reduces the contact with potential carcinogenic compounds in the intestinal wall. The best sources of dietary fibers are whole grain products such as oatmeal, cereals, whole grain bread, and whole grain flour. Vegetables also contain a lot of dietary fibers. The most soluble dietary fibers are found in dry legumes and oatmeal. The most insoluble dietary fibers can be found in wheat bran, corn bran, and barley bran, as well as in nuts and seeds. Dietary fibers are particularly important for people who want to lose weight. The daily requirement for this nutrient is 25-42 g. Dietary fibers aid in the removal of excess fat from the digestive tract and have the ability to bind water, thereby swelling in the stomach, filling it, and providing a longer-lasting feeling of satiety. However, if the water intake is insufficient, fibers will not be able to perform their function, which can lead to constipation. Therefore, it is important to note that when increasing the intake of this nutrient, larger amounts of fluid should also be provided.

Supplementation of dietary components - fiber

During supplementation of fiber, it is crucial to bear in mind that it should not be applied by individuals experiencing inflammatory states and other ailments of the digestive system. Fiber collaborates effectively with herbs such as parsley and hibiscus, which promote the regeneration of the intestinal lining. It is advisable to ensure adequate water intake during fiber supplementation! It is recommended to gradually increase the fiber dosage.
