ISLAMABAD: Lung cancer, the frequently identified cancer globally might be affected not just by smoking and air pollution but also, by dietary factors according to recent studies.
In 2022 lung cancer represented 12.4% of all cancer diagnoses rendering it the most frequently identified type. Additionally, it was the fatal responsible, for 18.7% of all deaths linked to cancer during that period.
The Role of Diet in Lung Cancer Risk
A research article appearing in the Annals of Family Medicine examined information from, then 1,700 people diagnosed with lung cancer and followed their health over a 12-year period. The investigators discovered that some glycemic carbohydrates, which quickly elevate blood glucose levels are linked to a higher risk of lung cancer.
Foods like bread, sweet treats and processed items were associated with quicker increases, in blood sugar while whole grains, seeds, fruits, vegetables, legumes and unsweetened dairy did not cause the same reaction.
Intake of glycemic foods raised the likelihood of lung cancer by as much as 13% whereas a diet abundant in nutritious carbohydrates, fiber, protein and healthy fats might lower the risk by, up to 28%.
Smoking Still the Leading Cause
Researchers highlighted that smoking continues to be the cause of lung cancer accounting for roughly 85% of instances though eating patterns and air contamination also have an important impact.
Previous studies, including one published in Thorax in July 2025 showed that ultra-processed foods like burgers, fries, pastries, soft drinks and packaged snacks increase the likelihood of lung cancer. These foods contain amounts of sugar, salt and synthetic additives but are deficient, in fiber and other beneficial nutrients.
Although further studies are necessary to validate the results, the research has brought to light the role of a good diet in lowering the risk of lung cancer. It might be the case that restricting the intake of ultra-processed foods and opting for whole, nutrient-rich alternatives can help in the decreasing of lung cancer rates worldwide.
