Diet and adenocarcinoma of the lung: a case-control study in Uruguay.

Regular ingestion of diets rich in foods of plant origin may confer significant protection against the development of lung cancer.

This study investigated the role of diet in the development and prevention of lung cancer. Using food frequency questionnaires, researchers examined the diets of a large number of subjects living Uruguay. The lung cancer odds ratio of each participant in this study was also evaluated.

Researchers observed that frequent consumers of diets rich in plant foods, such as fruits, tubers, and carotenoids, had low chances of developing lung cancer. On the other hand, generous intake of diets high in red meat, cholesterol-containing, and fatty foods was found to increase lung cancer development risk. The results of this study suggest that high dietary ingestion of fats, red meat, and cholesterol-rich foods may elevate an individual’s odds of developing lung cancer.
