Fruit and vegetable diet linked to lung cancer in young non-smokers

Key Points:

• Early research presented at the AACR meeting suggests a surprising link between diets high in fruits, vegetables, and whole grains and lung cancer risk among younger non-smokers, based on data from 187 patients diagnosed at age 50 or younger.
• Researchers hypothesize that pesticide residues on conventionally grown produce may contribute to this association, noting that agricultural workers exposed to pesticides also show higher lung cancer rates.
• The study is observational, limited by self-reported dietary data and a small sample size, and does not prove causation; further research including direct measurement of pesticide levels in patients is planned.
• Experts emphasize the need for more investigation into environmental factors behind rising lung cancer rates in non-smokers, especially younger women, and recommend washing produce and choosing organic options when possible.
• Advocacy groups call for stronger policies to reduce pesticide exposure due to existing evidence linking pesticides to various cancers, while medical analysts caution that the findings raise questions requiring more extensive study.
