Nutrition can prevent and treat deficiencies in micronutrients (vitamins and minerals) and macronutrients (carbohydrates, proteins and fats) that may occur in some people with IBD.
Depending on which part(s) of the digestive tract is affected by the disease and inflammation, the effects on the person’s nutritional status can be quite different. We know that the majority of nutrients are absorbed in the small intestine. In Crohn’s disease, since the inflammation can be present anywhere in the digestive tract, including the small intestine, the nutrient absorption can be largely ineffective. On the other hand, in ulcerative colitis, deficiencies are less common since inflammation is solely located in the colon.
Even if they are not readily digestible, fibers play an important role in controlling bowel movement, even in active periods. A fiber-rich diet allows stools to be more voluminous, hence promoting normal bowel movement, with no diarrhea or constipation.
Soluble fibers are generally better tolerated during active phases of IBD than insoluble fibers. Fruits and vegetables without skin or seeds (banana, pears, carrots, etc.), some grains (oatmeal, white rice, etc.), creamy nut butters, psyllium (Metamucil) and inulin (Benefibre) are all great sources of soluble fibers.
A food journal, where you can also write down your symptoms, is the best tool. It will allow you to figure out which foods or which type of foods are problematic for you and cause your symptoms. A registered dietitian can help analyse your journal and tailor your diet to help control your symptoms.
