Ulcerative colitis is an inflammatory bowel disease affecting the lining of the large intestine. Ulcerative colitis causes inflammation, ulcers, and diarrhea. Dietary changes can sometimes help improve the symptoms of colitis and Crohn’s disease. It is advisable to take foods such as vegetables, fruits, lean meat, eggs, low-fat dairy, eggs, and white rice if you are suffering from inflammatory bowel disease:

1. Carbonated beverages
Carbonated drinks, such as soda can trigger inflammatory bowel disease flare-ups. The gas in these drinks can cause bloating, pain, and cramping. Carbonated drinks can also irritate the already inflamed lining of the intestine. Drink enough water instead

2. Butter or margarine
Hydrogenated fats such as butter and margarine are high in fat and should be avoided if you are suffering inflammatory bowel disease. Fat can aggravate symptoms by irritating the already inflamed lining of the intestine. Hydrogenated fat is hard to digest and can slow down the movement of food through the digestive tract, leading to cramping and pain.

3. Dairy products
Products such as milk are common triggers for ulcerative colitis flare-ups. Dairy can be difficult to digest, especially for people with inflammatory bowel disease. Milk contains a type of sugar called lactose that can also trigger symptoms.

4. Corn
This grain is a good source of fiber, which can help to bulk up stools and make them easier to pass. It contains a type of soluble fiber that can ferment in the colon and cause gas and bloating. It is a high-glycemic food, which causes spikes in blood sugar levels that can trigger inflammation.

5. Alcohol
Alcohol can irritate the lining of the intestine and increase inflammation. Alcohol can also interfere with the absorption of medications used to treat inflammatory bowel disease, such as mesalamine

6. Coffee or caffeine
Coffee increases stomach acid production, which can aggravate symptoms like heartburn and indigestion. Coffee can also stimulate the bowels, leading to diarrhea and abdominal pain. Caffeine is a stimulant that can worsen symptoms like anxiety and jitteriness and lead to dehydration, which can exacerbate inflammatory bowel symptoms. Alternatives like decaf coffee or herbal tea may be easier for your gut

7. Spicy food
Capsaicin, the compound that makes chili peppers hot, can irritate the already inflamed lining of the colon and cause pain. Spicy food can also worsen colitis symptoms such as diarrhea.
Diet is an important part of managing ulcerative colitis. Experimenting with your diet to see what works for you is important. Avoiding trigger foods and eating anti-inflammatory foods may help to improve your symptoms. If you are unsure about which foods to eat or avoid, speak to a registered dietitian or your doctor.
