Diverticulitis represents a common digestive condition that affects the large intestine. It involves the inflammation or infection of small pouches, known as diverticula, that can form in the colon lining. Individuals often have questions about which foods are appropriate, especially concerning certain items like seeds and nuts.
The Seed and Nut Myth Debunked
For many years, it was commonly believed that small food particles like blackberry seeds, nuts, corn, and popcorn could get lodged in diverticula and cause inflammation. However, recent medical evidence and large-scale studies have refuted this misconception. The American Gastroenterological Association (AGA) now advises against avoiding these foods.
A study of over 47,000 men found no increased risk of diverticulitis with nuts, corn, or popcorn. Higher intake of these foods was associated with a lower risk, suggesting a protective effect. These foods contribute beneficial fiber to the diet, which is important for gut health. There is no scientific basis to avoid blackberry seeds for diverticulitis.
Understanding Diverticulitis
Diverticulitis occurs when diverticula, small pouches in the colon, become inflamed or infected. These pouches are common, particularly as people age, a condition called diverticulosis. While diverticulosis often presents without symptoms, diverticulitis can cause sudden and severe symptoms.
Common symptoms include abdominal pain, frequently in the lower left side. Other symptoms include fever, nausea, vomiting, and changes in bowel habits (constipation or diarrhea). Risk factors for developing diverticulitis include increasing age, a diet low in fiber and high in red meat, obesity, smoking, and lack of physical activity. Certain medications, such as NSAIDs and steroids, are also associated with an increased risk.
Dietary Recommendations for Diverticulitis
Dietary recommendations for diverticulitis vary depending on whether an individual is experiencing a flare-up or is in remission. During an acute flare-up, a clear liquid diet is often recommended to allow the digestive tract to rest. This includes clear broths, pulp-free fruit juices, gelatin, and water. As symptoms improve, a low-fiber diet is introduced slowly.
During remission, a high-fiber diet is advised to prevent future episodes and promote digestive health. Fiber helps soften stool and facilitates its passage through the colon, reducing pressure within the digestive tract. Adequate fluid intake is also important for fiber to move smoothly. Nuts, seeds, corn, and popcorn are safe to consume as part of a balanced, fiber-rich diet during remission. Regular physical activity further supports bowel function and helps prevent constipation.
