Soy food consumption and lung cancer risk: a meta-analysis using a common measure across studies.

​High dietary ingestion of soy foods, especially among non smokers, may help keep lung cancer at bay.

The purpose of this research work was to review epidemiological studies that examined the association between soy food intake and lung cancer risk. Researchers analyzed data and evidence extracted from 11 epidemiological studies that investigated this association.

Researchers observed that individuals who consumed high amounts (in grams) of soy protein daily had less chances of having lung cancer. The lung cancer-inhibiting effect of soy protein was found to be stronger in non-smokers than in smokers. The results of this study demonstrate that eating large portions of soy foods daily can protect individuals, particularly non-smokers, from lung cancer.
