You don’t smoke, you know your family history of every cancer under the sun (including skin cancer) and you never fall behind on an annual checkup.

But there’s still something — well, a lot, actually — you can do to slim your cancer risk. Namely, watch what you eat. Your food choices can either increase or decrease your risk of cancer in a big way, with poor nutrition contributing about 30 percent of all diagnosed cancer cases, according to Anna Taylor, a registered dietitian at the Cleveland Clinic.

And while being overweight or obese is linked with an increased risk for 10 different types of cancers, including breast, pancreatic, endometrial and colon cancers, a multitude of healthy weight-supporting foods also contain certain phytonutrients, vitamins and minerals that have anti-carcinogenic effects. “These nutrients help protect the body from carcinogens in the environment and reduce DNA damage,” Taylor says. “Many unprocessed foods, especially plant foods, contain a variety of these compounds that work together synergistically to decrease cancer risk.” (FYI, that’s why whole foods, not isolated supplements, are best for reducing cancer risk.)
