Snack on red grapes.KriangKan/Shutterstock
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.
Try to walk 30 minutes a day.VTT-Studio/Shutterstock
More than two dozen studies have shown that women who exercise have a 30 to 40 percent lower risk of breast cancer than less active women, according to the Fred Hutchinson Cancer Research Center. Moderate exercise lowers blood estrogen levels, a hormone that can affect breast cancer risk. Another study linked four hours a week of walking or hiking with cutting the risk of pancreatic cancer in half. The benefits are probably related to improved insulin metabolism due to the exercise.
