Which diet is commonly associated with the development of diverticulosis?

Diverticulosis is a condition characterized by the presence of pouches (diverticula) that form in the walls of the colon, and its development is significantly linked to dietary habits. A low fiber diet is particularly associated with the development of diverticulosis because dietary fiber plays a crucial role in maintaining healthy bowel function and promoting regularity. When fiber intake is insufficient, the stool may become harder and more difficult to pass, leading to increased pressure in the colon. This elevated pressure can contribute to the formation of diverticula as the colon wall weakens.

In contrast, a high fiber diet can help prevent diverticulosis by improving bowel movements and reducing the strain on the colon. It is well-established that populations consuming a diet rich in fruits, vegetables, and whole grains—high in fiber—tend to have a lower incidence of diverticulosis. The other choices, including a high protein diet, balanced diet, and ketogenic diet, do not have the same strong association with the condition, as they do not directly relate to the fiber content necessary for optimal colon health. Thus, the connection between a low fiber diet and diverticulosis development is well-supported by clinical findings and dietary recommendations.
