Seven (Easy to Find) Foods That May Help Prevent Cancer
Reach for these super foods to supercharge your odds of staying ahead of cancer and maximizing your health.
Garlic: Stinky Breath, but Super Healthy
Whoever thought garlic breath would be good for you? The same sulfur
compounds causing that odor may also stop cancer-causing substances from
forming in your body, speed DNA repair, and kill cancer cells.
Want more? Garlic battles bacteria, including H. pylori (the one connected
to some ulcers and stomach cancer), and it reduces the risk of colon
To get the most benefit, peel and chop the cloves and let them sit 15 to 20
minutes before cooking. That activates enzymes and releases the
sulfur-containing compounds that have the most protective effect, says Doyle.
And stick with the cloves, not the dietary supplement. "There is no solid
evidence that dietary supplements are going to reduce your cancer risk,"
Garlic is the powerhouse of the allium family, but onions, leeks, chives,
and scallions might also protect against stomach cancer, some research
Broccoli: Phytochemical Powerhouse
Eat your broccoli, mom always said. She was right. Broccoli and other
cruciferous vegetables such as cabbage, kale, and cauliflower contain
phytochemicals called glucosinolates, which produce protective enzymes that are
released when you chew the raw veggie, rupturing the cell walls.
Your body also produces those enzymes in the intestines, Fahey explains, and
when raw or cooked broccoli passes through, the enzymes are activated.
One of the most protective of these enzymes is sulforaphane. "Broccoli is
the best source of this particular compound," says Fahey, who studies
sulforaphane in broccoli and broccoli sprouts. Scientists are researching how
sulforaphane might reduce cancer risk, from detoxifying harmful substances
(such as smoke and other environmental pollutants) in the body to operating as
a kind of antimicrobial agent by attacking the bacterium H. pylori.
Broccoli and its cousins are most protective against cancers of the mouth,
esophagus, and stomach, according to a review of hundreds of clinical studies
conducted for the World Cancer Research Fund and the American Institute for
So do what mom always said. Steam broccoli and toss with garlic and olive
oil for a healthy dish -- no greasy cheese sauce required. Or just nibble on
some raw florets.
Tomatoes: Potential Weapon Against Prostate Cancer
The red coloring in tomatoes makes a juicy, ripe one hard to resist -- and
makes them a potential weapon against prostate cancer. That red hue comes from
a phytochemical called lycopene, a powerful antioxidant, which is most
concentrated in tomatoes. Several studies suggest that a lycopene-rich
diet is connected to a reduced risk of prostate cancer. However, researchers
aren't yet sure if this is related directly to lycopene itself or some other
In laboratory tests, lycopene has stopped other types of cancer cells from
growing, including breast, lung, and endometrial (in the lining of the uterus).
Researchers speculate that lycopene protects cells from damage that could lead
to cancer by boosting the immune system. And they suspect lycopene stops the
growth of tumors by interfering with abnormal cell growth, according to the
American Institute for Cancer Research.
To get the most benefit from lycopene, eat cooked or processed tomatoes,
including tomato juice and pizza sauce. Processing makes the cancer-fighting
compounds more available to your body because heat breaks down the plant's cell
walls. And including processed tomatoes in dishes with oil such as pizza and
pasta with sauce boosts the availability of lycopene. Want more of this
compound? Munch on some watermelon, pink grapefruit, or red bell peppers.
