Eat less red meat
Unfortunately, red meat has also gotten a bad rap when it comes to a diet for preventing cancer. IARC classifies it as a ‘possible carcinogen,’ and the American Cancer Society recommends a diet low in red meat. ‘Ideally, we should be thinking of red meat as we do lobster, having it for a special occasion if we like it,’ Dr. Wu says. ‘This is how red meat is consumed in many traditional eating cultures, such as the Mediterranean diet.’ The American Institute for Cancer Research suggests limiting red meat to 18 ounces per week.
