Es ist wichtig, die Bedeutung von Nahrungsfasern in unserer täglichen Ernährung zu kennen, insbesondere für die Jüngsten. Es handelt sich um eine andere Bezeichnung für diesen Bestandteil – eine Art von Mehrfachzucker, auch komplexe Kohlenhydrate genannt. Es wird nicht verdaut und im Dünndarm absorbiert, daher ist es keine Energiequelle. Dennoch hat es eine große Bedeutung für das Verdauungssystem aufgrund seiner physiologischen Eigenschaften.
Fiber for aiding weight loss
Fiber is divided into soluble and insoluble fractions in water. The insoluble fraction influences the function of the digestive tract, stimulating the peristaltic movements of the intestine, increasing the process of saliva secretion, and increasing body weight. It binds water, buffers and binds excess salty acid to the stomach, which helps prevent many intestinal diseases. The soluble fraction is a nutrient for the gut microflora. Products with a high fiber content have a large volume, causing a feeling of satiety, which leads to a large amount of fruits and vegetables in the diet. Fiber is also found in whole grain products, especially in wheat bran, as well as in seeds of plants, whole grains, cabbages, root vegetables and nuts. The soluble fraction is found in legumes, oat flakes, some fruits and vegetables. In addition to being a nutrient for bacteria, it lengthens the time of intestinal passage by increasing the density of food content. Beta-glucans and pectins, the components of the soluble fraction, lower postprandial glucose levels and also affect the lowering of cholesterol levels in the blood by binding bile acids and excreting them in the stool. Another advantage of a fiber-rich diet is the increase in fat excretion from the body and the delay in the absorption of triglycerides.
Functions of dietary fibers
Dietary fibers present in the gut in the form of gel hinder glucose absorption, leading to a decrease in its solubility and release of insulin. This mechanism can help prevent chronic obesity, diabetic disorders, and overweight. Societies that consume more fiber-rich foods are less prone to chronic cardiovascular diseases, experience fewer heart attacks, and suffer less from constipation. This is due to water-soluble fibers, which bind bile acids, lipids, and cholesterol. Adequate fiber intake is necessary to maintain a normal lipid profile. Fibers also bind carcinogens and toxins, reducing the risk of colorectal cancer. Insoluble fibers improve gastrointestinal motility and prevent chronic constipation. However, it is important to note that adequate fluid intake is required to ensure that the dietary fibers achieve the desired effects.
Comprehensive Summary
Repeated scientific research has confirmed the positive effects of consuming dietary fiber on humans. There are many products available on the market that have been enriched with high fiber content and simultaneously support the weight loss process. However, the best solution is to enrich your diet with fiber from food sources, as fiber in tablet form is not always sufficient to effectively support the body. By incorporating fiber-rich products into our diet, we also provide the body with a wide range of essential vitamins and minerals, which contributes to the development of healthy habits.
