Black Raspberries
All berries are packed with cancer-fighting nutrients. But black raspberries, in particular, contain very high concentrations of phytochemicals called anthocyanins, which slow down the growth of premalignant cells and keep new blood vessels from forming (and potentially feeding a cancerous tumor), according to Gary D. Stoner, PhD, a professor of internal medicine at The Ohio State University College of Medicine. Helps fight: colon, esophageal, oral, and skin cancers
How to take: Stoner uses a concentrated berry powder in his studies but says a half-cup serving of berries a day may help your health, too.
Tomatoes
This juicy fruit is the best dietary source of lycopene, a carotenoid that gives tomatoes their red colour, Béliveau says. And that's good news, because lycopene was found to stop endometrial cancer cell growth in a study in Nutrition and Cancer. Endometrial cancer causes nearly 8,000 deaths a year. Helps fight: endometrial, lung, prostate, and stomach cancers
Prepare: The biggest benefits come from cooked tomatoes (think pasta sauce!), since the heating process increases the amount of lycopene your body is able to absorb.
Walnuts
Walnuts contains phytosterols (cholesterol-like molecules found in plants) have been proved to block estrogen receptors in breast cancer cells, possibly slowing the cells' growth, says Elaine Hardman, PhD, associate professor at Marshall University School of Medicine in Huntington, West Virginia. Helps fight: breast and prostate cancers
Your Rx: Munching on an ounce of walnuts a day may yield the best benefits, Hardman's research found.
