We don’t need to see the pictures on the back of cigarettes cartons to know that smoking is bad for our lungs. It puts us at greater risk of cancer and shortens our life. For this reason it’s not hard to see that if proper health into old age is something you want, laying off the smokes is an intelligent place to start.

Outside of quitting smoking, are there other things we can do to protect our lungs and lower our risk of cancer? There is, according to new research from BBC Health. The study suggests that men who eat soy may have a lower risk of lung cancer. The Life Extension Blog has more:

Soy contains isoflavones, which act similarly to the hormone estrogen, and may have anti-cancer qualities in hormone-related cancers of the breast and prostate.

Cells in the lung have properties that suggest they may also respond to isoflavones. Researchers studied more than 36,000 men and more than 40,000 women, 45 to 74 years old and free of cancer at the start of the study.

Among the slightly more than 13,000 men who never smoked, there were 22 lung cancer cases among men who ate the least soy, and just 13 lung cancer cases among those who ate the most. Men’s soy intake from food varied widely, from about 34 to about 162 grams per day.

Outside of smoking, soy may be one other alternative to maintaining healthy lungs and living a long life. Make sure to check out the full article for more details of the study.
