When it comes to fruits and vegetables, brighter means healthier. Dr. Hilary Wu, president of IU Health Central Indiana Cancer Centers, said nutrients from produce are essential to preventing cancer.
Folic acid, found in leafy vegetables, is known to have anti-cancer powers, Wu said. "The folic acid is known to decrease the risk for breast cancer and colon cancer."
Wu says eating animal fat contributes to many types of cancer. Marsh dietitian Mary Snell recommends poultry, pork and seafood. And when you reach for red meat, Snell says try for cuts that have the word "round" or "loin." And, don't discount soy.
Wu says whole grains can cut your chance for colon cancer. Snell said it's easier than ever to find delicious whole grains in stores. Even couscous is coming in a variety of flavors.
Tobacco? Don't even think about it.
Wu says limiting alcohol consumption is another important step in the prevention plan.
Lastly, sneak in some exercise here and there during your shopping trip. Walk to the store if possible, and pick up a basket -- instead of a cart -- on your way in.
