Diet and Risk for Incident Diverticulitis in Women: A Prospective Cohort Study
1531 cases of incident diverticulitis for 415 103 person-years of follow-up were identified. Intake of peanuts, nuts, and seeds (aHR,1.07 [95% CI, 0.91 to 1.25]) and fresh fruits with edible seeds (aHR,1.06 [CI, 0.90 to 1.24]) was not associated with incident diverticulitis. There was a reduced risk for incident diverticulitis in women in the highest quartile of healthy diets compared with the lowest quartile: the Dietary Approaches to Stop Hypertension diet (aHR, 0.77 [CI, 0.65 to 0.90]), the Healthy Eating Index (aHR, 0.78 [CI, 0.66 to 0.91]), the Alternative Healthy Eating Index (aHR, 0.81 [CI, 0.69 to 0.95]), and the Alternative Mediterranean diet (aHR, 0.91 [CI, 0.78 to 1.06]).
Background: Patients with diverticulitis often attempt to control their diet with a particular focus on avoiding nuts and seeds. However, whether dietary patterns or dietary intake of nuts and seeds are associated with diverticulitis risk is poorly studied, particularly in women. Objective: To deter...
