To reduce your risk of cancer, look no further than your fridge. "All the studies on cancer and nutrition point to eating plant-based foods for their phytonutrients and other special compounds," says Richard Béliveau, PhD, chair in the prevention and treatment of cancer at the University of Québec at Montreal and author of Foods to Fight Cancer.

Aim for five to nine daily servings of all kinds of fruits and vegetables—especially these six superstars.

Broccoli

All cruciferous veggies (think cauliflower, cabbage, kale) contain cancer-fighting properties, but broccoli is the only one with a sizable amount of sulforaphane, a particularly potent compound that boosts the body’s protective enzymes and flushes out cancer-causing chemicals, says Jed Fahey, ScD. A recent University of Michigan study on mice found that sulforaphane also targets cancer stem cells—those that aid in tumor growth.

Helps fight: breast, liver, lung, prostate, skin, stomach, and bladder cancers

Your Rx: The more broccoli, the better, research suggests—so add it wherever you can, from salads to omelets to the top of your pizza.
