New research confirms that nuts and seeds do not increase the risk of diverticulitis, challenging previous dietary advice. The study followed nearly 30,000 women with no history of the disease and found that those who adhered to healthy diets—such as the DASH diet, Mediterranean diet, and other balanced eating patterns—had a reduced risk of developing diverticulitis. These findings align with earlier research in men and suggest a shift in dietary recommendations. Experts now agree that a high-fiber diet, including nuts, seeds, fruits, and vegetables, supports colon health. While severe cases of diverticulitis may require surgery, most mild cases can be managed with diet and monitoring.
