Lots of factors can affect a person's cancer risk. This study doesn't claim
to have all the answers, and diet's role has been debated.
For instance, a 2003 study from the Netherlands showed that eating lots of
phytoestrogens may not prevent breast cancer.
People don't always perfectly recall their diets. No one was told to eat
certain foods to try to prevent lung cancer. That's partly why the researchers
call for more work on the topic.
Education, body mass index (BMI), and income were taken into account.
Supplement use, family history of cancer, exercise, and alcohol use weren't
The American Cancer Society recommends eating a variety of healthful foods,
especially plant-based foods. That includes consuming at least five daily
servings of various vegetables and fruits and choosing whole grains over
processed (refined) grains or sugars.

Coffee and teas watered down the results a bit. When these drinks were
included, lung cancer risk was 24% lower for people with the highest intake of
all phytoestrogens combined, compared to 46% lower for those with the highest
phytoestrogen intake from food sources alone.
