A total of 120,852 men and women (from the Netherlands Cohort Study) completed a baseline questionnaire and also a food frequency questionnaire at the beginning of the study, and after 20.3 years of follow-up, 583 incident pancreatic cancer cases appeared. The results of the study showed that increased total nut consumption was associated with a non-significantly decreased microscopically confirmed pancreatic cancer (MCPC) risk in men who consumed more than 10g/day compared to non-consumers. Peanut butter intake was related to a significantly reduced risk of MCPC in men who consumed more 5g/day compared to non-consumers.
