Remember Fibre to Promote A Healthier Gut with IBD
If you suffer from Irritable Bowel Disease (IBD) you may have significantly reduced the amount of fibre in your diet even when you are symptom free. What you may not know is the power fibre may have in reducing your risk of an IBD flare ups and disease severity. There are two types of IBD called Crohn’s disease (CD) and ulcerative colitis (UC). Each type of disease differs by where in the gut and the depth of damage within the gut lining. By including enough fibre in your diet, you may reduce the length of time you are diagnosed with IBD and the severe symptoms in all forms of IBD. If you suffer from CD by including more fibre in your diet you may decrease your risk of developing a flare up.
Fibre is important in promoting a healthy gut microbiome and gut environment and lining. Research of people with IBD concluded that those with the least amount of fibre in their diet had more hospital admissions, had a history of surgery, and suffered from the disease for more of their life.
People with CD who ate the least amount of fibre in their diet compared to those with the most fibre over a 6-month period were more likely to suffer from an IBD flare up. Those individuals who reported that they did not avoid high fibre foods had a 40% less likelihood of a flare up than those who restricted their fibre intake.
This is good news if you suffer from IBD and specifically CD. By being able to include more fibre in your diet it will also provide you with more freedom. A greater variety of plant foods in your diet does not only decrease boredom but gives your body more nutrients and allows your body to be healthier. If you do develop a flare up this is when fibre, specifically insoluble fibre, should be limited to prevent further aggravation and you need to follow the recommendations of your Accredited Practising Dietitian and doctor. However, when you are symptom free fibre is a beneficial part of your diet for many reasons including potentially reducing your risk of IBD flare ups.
Including a variety of plant food sources which include whole grains like Corn Thins slices each day can help you to achieve your fibre needs. An adult needs between 25-38g of fibre each day for gut and overall health.
Take home message: There is no need to fear fibre if you suffer from IBD. Fibre is a friend to your gut and its optimal function which may reduce your risk of complications and severity of IBD and flare ups for those with CD.
