But over the past 20 years, researchers have amassed an impressive array of evidence that fiber helps prevent colon cancer. For more fiber, eat high fiber cereal, bran flakes, rye crisp crackers, popcorn, toasted wheat germ, granola, high-fiber bread and beans. This soybean substance may lower the risk of a host of diseases including breast cancer because soy contains flavonoids, which are a source of phytoestrogen, a substance which chemically resembles estrogen.

But lifestyle also plays a role.
