According to researchers at the University of Erlangen-Nuremberg, Germany, a diet rich in fiber would reduce the risk of developing inflammatory joint diseases. Explanations.
We know that having a balanced diet is a guarantee of well-being and increases the chances of being healthy. But according to recent research conducted by scientists at the Friedrich-Alexander University of Erlangen-Nürnberg (FAU) in Germany, a high-fiber diet would have a positive influence on chronic inflammatory diseases of the joints.
The nature of intestinal bacteria
As the ScienceDaily website explains, everything happens at the level of intestinal flora. Each adult has about two kilograms of benign bacteria in their intestines, which help digestion by breaking down the fibers so they can be absorbed into the body. A natural process, also driven by short-chain fatty acids (SCFA) that provide energy, stimulate bowel movement and have an anti-inflammatory effect. If the different bacteria coexist harmoniously, they are able to protect the intestinal wall and help to block the pathogens. In short, the intestinal flora can either protect against the disease or provoke it, it depends on its composition.
But FAU researchers, under the direction of Dr. Mario Zaiss of the Department of Medicine 3 - Rheumatology and Immunology at Universitätsklinikum Erlangen, show that it is not the intestinal bacteria themselves, but their organic compounds that affect the immune system. . Focusing on propionate (C3) and butyrate (C4), both short-chain fatty acids that can for example be found in joint fluid, they discovered that a healthy diet high in fiber is able to change the nature of intestinal bacteria. They were able to demonstrate that a higher concentration of short-chain fatty acids (especially propionate), for example in the bone marrow, reduced bone degradation.
Towards a new treatment for inflammatory joint diseases?
"We have been able to show that a bacteria-friendly diet has an anti-inflammatory effect, as well as a positive effect on bone density," said lead author Mario Zaiss. "Our results offer a promising approach for the development of novel therapies for inflammatory joint diseases as well as for the treatment of osteoporosis.We are not in a position to give specific recommendations for a favorable diet for bacteria, but to eat Muesli every morning as well as enough fruit and vegetables throughout the day helps maintain a wide variety of bacterial species.
