Elevated intake of isoflavone-containing foods, such as soy foods, may help curb the development of cancerous cells and tumors in the lungs of never smokers.
This study determined if regular eating of isoflavone-rich foods, such as soy foods, is tied to lower risk of lung cancer in never smokers. Researchers used dietary information of 147,296 Japanese and Chinese men and women whose health was monitored for more than 13 years.
Researchers observed that greater intake of soy and other isoflavone-containing foods brightened non-smokers' chances of holding lung cancer at bay. The results of this study support dietary intake of isoflavones as a viable preventive measure against lung cancer.
