Fibre for the intestine
Fibre is healthy and good for digestion. As we all in fact know. Nevertheless, we do not pay too much attention to fibre: On average, we eat 20 g per day, but we should eat at least 30 g. Fruit, vegetables and wholemeal products are particularly rich in fibre. For our digestive enzymes, fibre is really pure ballast, which they cannot break down. Yet some bacteria in our intestine are dependent on precisely this fibre.
Ballast for rapid intestinal movements
By the time the fibre reaches the large intestine, it is pure ballast. It increases the content of the intestine, thus reducing the energy density and causing the blood sugar level to rise less strongly after a meal. Furthermore, the greater content of the intestine increases the pressure on the intestinal wall, which stimulates the intestinal movements. This means: We can extract fewer nutrients and toxic substances from the content of the intestine. Fibre therefore has an effect on our weight. At the same time, it can detoxify.
Fibre: Food for intestinal bacteria
When the fibre enters the large intestine, the intestinal flora acts on it. If above all the useful intestinal bacteria process the fibre compounds, experts call them "prebiotics". As the intestinal flora perform important functions for our health, we benefit from well nourished intestinal flora. It is therefore advisable to ensure a sufficient supply of nutrients for the bacteria. Resistant starches and oligofructose are particularly suitable as nutrients, as they support the intestinal bacteria that produce butyric acid.
Fibre is not just fibre
Most fibres consist of carbohydrates. However, they differ in structure and bind water to varying degrees. Resistant starch, inulin, oligofructose and pectin are among the water-soluble fibres, cellulose is an example of a water-insoluble fibre. Resistant starch type 3 is a very good nutrient for intestinal flora, and at the same time provides the best exploitation of the mucous membrane nutrient butyric acid. An adult should ingest 10 to 15 g daily. Resistant starches may appear in many foods, depending on preparation, but they seldom constitute more than five per cent of the overall starch content. For example, resistant starch type 3 can be found in boiled potatoes, peas, beans and bread as soon as they have cooled. However, the quantities are small. SymbioIntest The new dietary supplement SymbioIntest contains resistant starch type 3.
Resistant starch becomes mucous membrane nutrient butyric acid
Some of the intestinal bacteria that break down the resistant starch in the large intestine cause butyric acid to form. The intestinal mucosa and the arteries in the intestinal wall depend on the butyric acid of the bacteria. A sufficiently high butyric acid level in the intestine is therefore important. If the intestinal mucosa is well nourished, it can form an effective barrier to toxins and pathogens, and also prevent the natural intestinal flora from penetrating the tissue. However, if the butyric acid level decreases, there are consequences for the intestine. The intestinal villi regenerate and the intestinal mucosa alters, increasing the risk of chronic inflammatory diseases of the intestine and bowel cancer. But the butyric acid can do even more: It acidifies the intestinal environment, thus reducing the activity of enzymes that create carcinogenic materials. In addition, it acts against inflammation.
A fibre-rich diet
- reduces the energy density of the nourishment and prevents overweight
- increases and extends the sense of satiation
- positively influences the cholesterol level
- prevents irritable bowel syndrome and constipation
- prevents tooth decay
Prebiotics that promote butyric-acid-forming bacteria
- stabilise the intestinal flora by supplying bacterial nutrients and promoting useful bacteria
- improve nutrition and thus the barrier function of the intestinal mucosa, which strengthens the immune system
- prevent type 2 diabetes and other diseases associated with obesity
- prevent chronic inflammatory diseases of the intestine and the development of bowel cancer
- prevent diseases in which the nerve cells are destroyed.
