The inflammatory bowel disease (IBD) are a group of chronic disorders that include ulcerative colitis and Crohn’s disease that cause inflammation in the intestine or digestive tract, leading to a variety of often painful problems. Research has shown that the lack of fiber could be a trigger for the development of these conditions, paving the way for new perspectives for the management and prevention of IBD.
Fiber plays a crucial role in promoting gut health. These components of our diet influence the gut microbiota and the mucus lining of the digestive system, providing a protective barrier and reducing inflammation. However, a recent study highlighted that fiber deprivation could contribute to the development of IBD.
The link between fiber and IBD
The study published in Cell Host & Microbe analyzed the role of fiber in the interaction between gut microbes and the mucus lining of the intestine. The results showed that dietary fibre, present in foods such as fruit, vegetables, whole grains and legumes, promotes the development of a healthy mucous thickness within the digestive tract. This mucous lining acts as a protective barrier, reducing inflammation and preventing the onset of IBD.
I study
Conducted on mice lacking interleukin-10a cytokine associated with IBDthe study revealed that fiber deprivation contributes to deterioration of the mucous lining of the colon, increasing inflammation and leading to fatal colitis. These findings clearly indicate that a high-fiber diet can offer significant protection against IBD.
The authors of the study intend to further investigate the research by examining the complex interaction between diet, intestinal microbiota and genetic predisposition as a possible path for reduce the development of IBD. This holistic approach could pave the way for new preventive and therapeutic strategies for this category of chronic diseases.
Although IBD is a complex and multifactorial condition, it is clear that diet plays a crucial role in their management and prevention. Some studies have shown that some forms of dietary fiber, such as unfermented β-fruits, may worsen IBD symptoms in some people. However, it is important to note that low-fiber formula diets, such as exclusive enteral nutrition (EEN), have been successful in reducing intestinal inflammation in some patients.
Nutrition advice for people with IBD
While it may be advisable to limit fiber consumption during acute IBD flare-ups to reduce gastrointestinal discomfort, it is important to keep in mind the long-term effects of a balanced, high-fiber diet in the management of IBD. Foods such as fruits and vegetables, whole grains and legumes can contribute to the diversification of the gut microbiome and promote better gut health in the long term.
I healthy intestinal bacteria they play a fundamental role in our overall health, contributing to the optimal functioning of the immune and digestive systems. A balanced, fiber-rich diet can encourage the growth of beneficial bacteria in the gut, reducing the risk of inflammation and improving overall gut function.
