According to a study, certain types of dietary fiber cause an inflammatory response in some patients, causing symptoms to worsen. Hence, the researchers claimed that the findings of the study can be used to make personalized dietary guidelines. 

In Canada, approximately 0.7%, or one in 150 people, has IBD, including Crohn′s disease and ulcerative colitis. The prevalence of this is predicted to grow by 1% in 2030. 

As per the findings of the study, specific types of fibers found in foods such as artichokes, chicory roots, garlic, asparagus, and bananas are especially hard to ferment if certain microbes are missing or malfunctioning. 

On the other hand, fiber has an anti-inflammatory effect and aids with digestion, but the researchers found that several select unfermented fibers increased inflammation and worsened the symptoms in some IBD patients.
