A colitis diet may contain fruits and vegetables; meat, poultry and fish; breads and cereals; and dairy products. Colitis diets may vary, and some people may benefit from eating a low-fiber diet or eliminating dairy. Anti-inflammatory foods such as walnuts and olive oil are also recommended on a colitis diet, according to WebMD.
A well-balanced diet that is high in protein, fresh produce, dairy and grains is generally recommended for people with colitis. Applesauce, cooked asparagus, steamed carrots, lettuce and skinned Idaho potatoes are types of produce that are low in fiber but high in nutrition, according to Everyday Health. Other types of produce such as seedless cucumbers, bananas, green beans, melons and peaches, and refined grains such as pasta and rice, may also be beneficial for those with colitis, according to WebMD.
Dairy sources such as yogurt have no fiber and provide beneficial probiotic bacteria to the digestive tract, helping to reduce inflammation. However, dairy is only suitable for those who tolerate lactose. Protein sources such as pork, lamb, chicken and fish are also fiber free and can be eaten if tender, according to WebMD.
Healthy oils such as olive and canola oils are good sources of fat that help fight inflammation, according to WebMD. Other anti-inflammatory fat sources such as coconut oil, walnuts and egg yolks are considered to be healthy when consumed in certain amounts and are high in beneficial linoleic acid. Similarly, the omega-3 in fish oil provides anti-inflammatory benefits, according to WebMD.
