Healthy-diet link to young-onset lung cancer in nonsmokers prompts pesticide questions

USC researchers found that healthier eating patterns (higher Healthy Eating Index scores with more fruits, vegetables, and whole grains) were associated with early-onset lung cancer in nonsmokers, particularly among women; researchers suggest pesticide exposure, not the foods themselves, may explain the link and call for further study. The study is observational, not peer-reviewed yet, and results were discussed at the AACR meeting; causality is not established and environmental factors are likely involved.
