A controversial study presented at the American Association for Cancer Research conference suggests eating fruits, vegetables, and whole grains may increase lung cancer risk. The research analyzed dietary data from 166 non-smokers under 50 who developed lung cancer, finding they consumed more produce than average Americans. Without peer review, the findings have drawn sharp criticism from nutrition experts.

This comes amid a broader trend of questionable health advice, with federal guidelines now emphasizing meat-heavy diets and influencers promoting nicotine as a wellness product. The study's lead researcher, Jorge Nieva from the University of Southern California, speculated that pesticides on produce might explain the association, despite lacking supporting data. Critics note the study's small size, arbitrary groupings, and absence of a control group.

Experts like Baptiste Leurent from University College London call the conclusions "quite striking" in their flaws. The findings contradict decades of evidence supporting plant-based diets for cancer prevention. With no published methodology or peer review, the study appears to be another example of sensationalized nutrition research that could confuse consumers already navigating conflicting health messages.
