In a study reported in The American Journal of Epidemiology earlier this year, researchers found “that greater adherence to the Paleolithic diet pattern and greater adherence to the Mediterranean diet pattern may be similarly associated with lower risk of incident, sporadic colorectal adenomas.” The authors suspect “evolutionary discordance” may explain the increase of colorectal neoplasms found in the Western dietary pattern.
Take home: Western dietary pattern is a significant departure from our evolutionary dietary pattern and may lead to more colorectal adenomas.
