Study Detects Unexpected Link Between Healthy Eating and Lung Cancer in Young Non-Smokers
A USC study of 187 lung cancer patients under 50, many non-smokers, found they tended to have healthier diets (average HEI 65 vs. 57 national). The cancer type differed from smoking-related cases; findings show association, not causation, and researchers consider environmental factors like pesticides. Limitations include small sample size and potential selection bias; more research is needed to determine if diet or pesticides contribute to risk and why women were more represented in this group.
