Eat less high-fat animal protein.Le Do/Shutterstock
After tracking food choices of more than 121,000 adults for up to 28 years, Harvard researchers found that people who ate three ounces of red meat every day were about 13 percent more likely to die—often from heart disease or cancer—before the study ended than people who didn’t eat meat. A Yale study found that women who ate the most animal protein had a 70 percent higher risk of developing non-Hodgkin’s lymphoma, while those who ate diets high in saturated fat increased their risk 90 percent. Switch to low-fat or nonfat dairy, choose poultry or fish instead of beef or pork, and use olive oil instead of butter.

They’re great sources of resveratrol, an antioxidant that may slow cancer growth in the lymph nodes, stomach, breasts, and liver. A 2011 study from The University of Texas Health Science Center found that resveratrol inhibited skin damage that ultimately leads to skin cancer. Although all grape skins contain resveratrol, red and purple grapes have the most. This is why you can never find grape ice cream.
When it comes to cancer-fighting foods, onions are nothing to cry about. Cornell food science researchers found that that onions and shallots have powerful antioxidant properties, as well as compounds that inhibit cell growth, which appear protective against a variety of cancers. The study found that shallots, Western Yellow, pungent yellow, and Northern Red have the richest sources of flavonoids and antioxidants. Not a big fan of onion breath? Although they have less antioxidant power, you can try scallions, Vidalia onions, or chives for a milder taste.
