In recent years, people have become more health-conscious and actively include vegetables, fruits, and whole grains in their diet. These foods are widely considered healthy and essential for a balanced lifestyle. But is that always the case? A new research discussion is now raising questions about whether even “healthy” foods could carry hidden risks, including cancer. Read on to know more.
Can Fruits, Vegetables Increase Cancer Risk?
A new study from the University of Southern California (USC) has suggested a possible link between eating a lot of fruits, vegetables, and whole grains and a higher risk of lung cancer in young people who don’t smoke. As per NDTV, but researchers are clear that the problem is not the food itself. They believe the concern may be pesticide residues that stay on conventionally grown produce.
The study looked at eating habits, smoking history, and background details of 187 lung cancer patients. All of them were 50 years old or younger when they were diagnosed. The findings were shared at the American Association for Cancer Research’s 2026 annual meeting.

More About The Research
Researchers used the Healthy Eating Index to measure diet quality on a scale of 100. According to NDTV, the patients in the study scored an average of 65, which is higher than the U.S. national average of 57. This means the group generally followed healthier diets than most Americans.
The participants reportedly consumed more servings of dark green vegetables, legumes, and whole grains compared to the average population. Women in the study showed especially high diet quality scores.
Dr. Jorge Nieva from the USC Norris Comprehensive Cancer Center, who led the research, explained that conventionally grown fruits, vegetables, and whole grains often carry more pesticide residues compared to foods like dairy, meat, and many processed items. He pointed out that exposure to pesticides could be one possible factor linked to the disease pattern.
He also noted that agricultural workers who directly handle pesticides have shown higher rates of lung cancer in earlier studies. According to him, a significant number of lung cancer cases appear in people who have never smoked, especially among younger individuals under 50 and increasingly among women.
Researchers also highlighted that these patients often followed healthier diets. However, they added that the study has limitations. The participants were self-selected.
