Ultra-Processed Food Intake and Smoking Interact in Relation with Colorectal Adenomas

Case-Control Study

Human

2020 Nov 14

This study found that smokers who eat a lot of ultra-processed foods (like chips, soda, and frozen meals) are much more likely to develop precancerous growths in their colon than smokers who eat less of these foods. Smoking and junk food together seem to make the risk much worse than either one alone.
