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 highly processed foods (like snacks and sugary dairy products) are much more likely to develop early colon growths than smokers who don’t, even when accounting for how unhealthy their overall diet is. So, it’s not just smoking or eating badly—it’s specifically eating lots of ultra-processed stuff that’s extra risky for smokers.
