In November 2018 researchers from Iran published their review of the medical scientific literature to assess the association between a dietary inflammatory index score and the risk of cancer. A total of 10 studies were included in the review. Results showed that that the most pro-inflammatory diets were significantly associated with an increased risk for cancer when compared with the most anti-inflammatory diets.
