2. Nuts and Seeds
Despite being nutrient-dense, nuts and seeds are often discouraged for individuals with diverticulitis due to their small size and hard texture. The concern is that these small particles may become lodged in the diverticula, potentially causing discomfort, inflammation, or infection.
Opting for nut butters or finely ground seeds is a safer alternative, providing the nutritional benefits without the risk of irritation to the digestive tract.
