Ulcerative colitis is an inflammatory bowel disease that causes inflammation and sores or ulcers in the digestive tract. Ulcerative colitis affects the large intestine, and there is no permanent cure for the condition . However, some management options can help keep the symptoms at bay. One of the most crucial management tips is changing food and nutritional habits. Here are some foods that one must avoid to prevent inflammation or discomfort. Dairy products It is observed that those with UC are often lactose intolerant and have trouble properly digesting. The trigger here is not dairy per se but the small intestine’s inability to digest the sugar found in milk with the help of an enzyme called lactase. This indigestion leads to abdominal pain and even diarrhea in some cases. Therefore, it is best to avoid dairy and dairy products like milk or cheese, but if you want to add them to your meal plan, consult nutritional experts about adding lactase supplements to ease digestion. Processed foods It includes packaged breakfast cereals, canned vegetables, sausage, ham, salami, and microwave-ready meals. Processed food products are often high in trans fat, which is known to cause a higher risk of developing ulcerative colitis.
