No specific foods are definitively known to trigger diverticulitis attacks. Despite previous dietary recommendations, there’s no conclusive evidence to suggest that avoiding particular foods prevents diverticulitis.
Diverticulitis occurs when diverticula, which are small bulging pouches in the large intestine, become inflamed or infected. This inflammation can lead to symptoms such as abdominal pain, fever, and changes in bowel habits.
These pouches, diverticula, are common and often don’t cause problems. The condition of having diverticula is called diverticulosis. It’s only when these pouches become inflamed that diverticulitis develops.
Historically, patients with diverticulosis were advised to avoid nuts, seeds, and popcorn. The theory was that these small food particles could get trapped in the diverticula and cause inflammation, leading to diverticulitis. However, current research does not support this link. There is no scientific proof that these foods are responsible for causing diverticulitis.
Instead of focusing on eliminating specific foods, individuals with diverticulosis should prioritize a healthy, high-fiber diet. Foods rich in fiber include:
- Fruits and vegetables, offering a wide array of vitamins and minerals.
- Whole grains, such as brown rice, whole wheat bread, barley, and quinoa, providing sustained energy and nutrients.
- Legumes, including beans, peas, and lentils, which are excellent sources of protein and fiber.
- Nuts, offering healthy fats, fiber, and various nutrients.
A high-fiber diet is beneficial because it softens stools, allowing them to pass more easily and quickly through the colon. This reduces pressure within the digestive tract, the system responsible for food digestion and nutrient absorption. Lowering pressure in the digestive tract is thought to decrease the likelihood of diverticula forming and subsequently becoming inflamed.
If you suspect you are experiencing a diverticulitis attack, it is important to consult with your healthcare provider.
Your doctor may recommend a temporary clear liquid diet to help manage an acute diverticulitis episode. This diet consists of easily digestible clear liquids like water, broth, and plain gelatin.
Following a clear liquid diet for a short period allows the digestive system to rest and recover. It’s crucial to discuss with your healthcare professional how and when to gradually reintroduce solid foods back into your diet.
