Healthy Diet Tied to Early-Onset Lung Cancer in Young Non-Smokers, Early Study Finds

An observational study of 187 lung cancer patients diagnosed at age 50 or younger found that non-smokers with healthier diets—rich in fruits, vegetables and whole grains—were more represented than the general population, prompting researchers to hypothesize that pesticide residues on conventionally grown produce may contribute to the link. The study is not peer-reviewed and relies on self-reported intake, with potential biases; investigators plan future pesticide measurements in blood/urine. The results show an association, not causation, and experts call for more research while recommending produce washing and, when possible, organic choices.
