July. 16,2025
Learn about the foods that may trigger diverticulitis symptoms and those that can be safely included during flare-ups. This guide highlights common irritants like spicy foods, cruciferous vegetables, and fatty meals, along with recommended low-fiber options and lifestyle tips to manage the condition effectively.

Top Foods to Avoid if You Have Diverticulitis
Diverticulosis occurs when small pouches form along the intestinal walls. If these pouches become inflamed or infected, it can lead to diverticulitis, a condition with unclear exact causes. Recognizing certain foods that may worsen symptoms is crucial for managing the condition.
Foods that can worsen diverticulitis
- Spicy dishes
Spicy foods, such as Indian or Chinese cuisine with red chilies, can irritate the digestive tract, causing symptoms like vomiting and diarrhea.

- Cruciferous vegetables
Vegetables like broccoli and cabbage may cause bloating and discomfort for individuals with diverticulitis. They can lead to gas and, in some cases, harder stools. - Corn
Corn contains high fiber and sugar, which can cause digestive complications. Processed cream corn might be better tolerated due to lower fiber and sugar content. - Dairy products
While not everyone is lactose intolerant, dairy can cause flatulence and diarrhea in diverticulitis patients. Lactose-free options like certain cheeses, yogurt, and plant-based milks are preferable. - Red and green peppers
Peppers may increase gas production and cause cramps. Monitoring your body's reaction before including them in your diet is advisable. - Legumes
Beans and lentils, rich in fiber, may trigger gas and bloating, so assess tolerance before consuming. - Greasy foods
Fast foods such as pizzas and burgers can inflame the intestines and cause abdominal pain. Reducing fatty, fried foods is recommended. - High-fiber foods
Lentils and other high-fiber foods may cause bloating. Limit or avoid them based on your reaction. - Butter and hard cheeses
These dairy fats might lead to digestive issues. Switching to olive oil spreads and lactose-free cheeses can be gentler on your stomach.
Recommended foods during diverticulitis flare-ups
- Low-fiber foods
Options include white rice, bread, pasta, cooked poultry, eggs, and fish. Incorporate canned peaches, apple sauce, and clear fruit or vegetable juices. Use olive oil for cooking, and include cooked vegetables like carrots and spinach. - Clear liquids
In phase with symptoms, opt for clear broths, ice pops made from fruit puree, and finely chopped soft fruits to soothe your digestive system.
