For Men, Eating Soy May Reduce Lung Cancer Risk

Source: Reuters Health (Summary by NIM)

For non-smoking men, chowing down on a lot of soy products may lower their overall risk of lung cancer, a new study suggests.

The antioxidant isoflavones found in soy are best known for their protective qualities in reducing breast and prostate cancer risk. According to a new Japanese study, lung cells may also respond favourably toward soy isoflavones, similarly protecting them from cancer.

While this study seems promising, a lot more work is required before any conclusions can be drawn. There were a few flaws in the study design so the researchers can't say for sure if it's really the soy products themselves that protect against cancer, or the lifestyle behaviours that go along with eating soy that make the difference.

Nonetheless, it's always a good idea to change up the protein sources in our diets throughout the week, and including more plant-based foods is great way to do that!
