The total number of cases varies slightly between nut, corn and popcorn consumption due to missing information for individual food items. For diverticular bleeding, information on recent intake (simple updating) was missing for nuts in 62cases, for corn in 64 cases, and for popcorn in 65 cases.
Values have been adjusted for age; study time period; body mass index; physical activity; total daily caloric intake; intake of nuts, corn, popcorn, fat (total), fiber, and red meat; current use of non-steroidal anti-inflammatory drugs; current use of acetaminophen; and current cigarette smoking. Dietary information was updated every 4 years; age, body mass index, physical activity, and medication use and cigarette smoking were updated every 2 years.
