USC Study Links Healthy Diets to Higher Lung Cancer Risk in Young Nonsmokers

  • USC researchers found a surprising association between healthy diets rich in fruits and vegetables and young-onset lung cancer in non-smokers. Lead investigator Dr. Jorge Nieva suggests pesticide residue on produce, rather than the food itself, may explain the increased risk.
  • The Epidemiology of Young Lung Cancer Project surveyed 187 patients diagnosed before age 50, with women accounting for 78% of the cohort. Participants displayed higher-than-average diet quality scores, averaging 65 on the Healthy Eating Index compared to the national average of 57.
  • Nieva theorizes that commercially produced, non-organic produce may carry higher pesticide residues linked to cancer than organic or processed foods. The team plans to confirm this link by directly measuring pesticide levels in blood and urine samples from patients.
  • Researchers also identified a significant association between oral contraceptive use and young-onset lung cancer; around 77% of women in the EGFR pathway and mixed mutation groups reported using them prior to diagnosis.
  • Experts emphasize these findings do not suggest avoiding fruits or vegetables, as healthy eating remains vital to overall health. Researcher Yashar noted that results do not suggest produce alone increases cancer risk, pointing instead to pesticide exposure as the likely culprit.
