They assessed diet through a food frequency questionnaire, and examined the relationship between nut intake and the most common type of esophageal cancer, which is high in this region of Iran. Nuts included were peanuts, walnuts, and mixed nuts/seeds
Total nut consumption was associated wth a reduced risk for esophageal cancer. Participants who consumed the most nuts had a 40% reduced risk of esophageal cancer compared to those who consumed none.
