Here are the worst foods for colitis

Diet plays a crucial role in managing colitis, and some foods can significantly worsen symptoms. High-fiber foods, such as raw vegetables, whole grains, and nuts, can be difficult to digest and may trigger diarrhea and bloating. While fiber is essential for overall gut health, insoluble fiber can be harsh on inflamed intestines.

Spicy foods are another common trigger. Ingredients like chili peppers and hot sauces contain capsaicin, which can irritate the digestive tract and cause discomfort. Fatty and fried foods, including fast food, greasy meats, and heavy sauces, are also problematic. They can slow digestion and lead to inflammation, exacerbating symptoms.

Dairy products, particularly milk, cheese, and butter, can be difficult to tolerate, especially for those with lactose intolerance. Even if you don’t have lactose issues, dairy can contribute to mucus production and worsen digestive symptoms. Gluten-containing foods, such as bread, pasta, and baked goods, may also trigger flares in people with gluten sensitivity or intolerance.

Artificial additives, preservatives, and highly processed foods, including chips, packaged snacks, and sugary cereals, can cause irritation. Acidic foods like tomatoes, citrus fruits, and vinegar-based dressings can also contribute to discomfort. Keeping a food journal to track personal triggers can help identify problem foods and improve colitis management.
