Top Cancer-Fighting Foods

Fighting Cancer by the Plateful

No single food can prevent cancer, but the right combination of foods may help make a difference. At mealtimes, strike a balance of at least two-thirds plant-based foods and no more than one-third animal protein. This "New American Plate" is an important cancer fighting tool, according to the American Institute for Cancer Research. Check out better and worse choices for your plate.

Fighting Cancer With Color

Fruits and vegetables are rich in cancer-fighting nutrients -- and the more color, the more nutrients they contain. These foods can help lower your risk in a second way, too, when they help you reach and maintain a healthy body weight. Carrying extra pounds increases the risk for multiple cancers, including colon, esophagus, and kidney cancers. Eat a variety of vegetables, especially dark green, red, and orange vegetables.

The Cancer-Fighting Breakfast

Folate is an important B vitamin that may help protect against cancers of the colon, rectum, and breast.  You can find it in abundance on the breakfast table. Fortified breakfast cereals and whole wheat products are good sources of folate. So are orange juice, melons, and strawberries.

More Folate-Rich Foods

Other good sources of folate are asparagus and eggs. You can also find it in beans, sunflower seeds, and leafy green vegetables like spinach or romaine lettuce. The best way to get folate is not from a pill, but by eating enough fruits, vegetables, and enriched grain products.

Pass Up the Deli Counter

An occasional Reuben sandwich or hot dog at the ballpark isn't going to hurt you. But cutting back on processed meats like bologna, ham, and hot dogs will help lower your risk of colorectal and stomach cancers. Also, eating meats that have been preserved by smoking or with salt raises your exposure to chemicals that can potentially cause cancer.

Cancer-Fighting Tomatoes

Whether it's the lycopene -- the pigment that gives tomatoes their red color -- or something else isn't clear. But some studies have linked eating tomatoes to reduced risk of several types of cancer, including prostate cancer. Studies also suggest that processed tomato products such as juice, sauce, or paste increase the cancer-fighting potential.

Tea's Anticancer Potential

Even though the evidence is still spotty, tea, especially green tea, may be a strong cancer fighter. In laboratory studies, green tea has slowed or prevented the development of cancer in colon, liver, breast, and prostate cells. It also had a similar effect in lung tissue and skin. And in some longer term studies, tea was associated with lower risks for bladder, stomach, and pancreatic cancers.

Grapes and Cancer

Grapes and grape juice, especially purple and red grapes, contain resveratrol. Resveratrol has strong antioxidant and anti-inflammatory properties. In laboratory studies, it has prevented the kind of damage that can trigger the cancer process in cells. There is not enough evidence to say that eating grapes or drinking grape juice or wine (or taking supplements) can prevent or treat cancer.

Limit Alcohol to Lower Cancer Risk

Cancers of the mouth, throat, larynx, esophagus, liver, and breast are all linked with drinking alcohol. Alcohol may also raise the risk for cancer of the colon and rectum. The American Cancer Society recommends limiting alcohol to no more than two drinks per day for men and one for women. Women at higher risk for breast cancer may want to talk with a doctor about what amount of alcohol, if any, is safe based on their personal risk factors.

Water and Other Fluids Can Protect

Water not only quenches your thirst, but it may protect you against bladder cancer. The lower risk comes from water diluting concentrations of potential cancer-causing agents in the bladder. Also, drinking more fluids causes you to urinate more frequently. That lessens the amount of time those agents stay in contact with the bladder lining.

The Mighty Bean

Beans are so good for you, it's no surprise they may help fight cancer, too. They contain several potent phytochemicals that may protect the body's cells against damage that can lead to cancer. In the lab these substances slowed tumor growth and prevented tumors from releasing substances that damage nearby cells.

The Cabbage Family vs. Cancer

Cruciferous vegetables include broccoli, cauliflower, cabbage, Brussels sprouts, bok choy, and kale. These members of the cabbage family make an excellent stir fry and can really liven up a salad. But most importantly, components in these vegetables may help your body defend against cancers such as colon, breast, lung, and cervix.

Dark Green Leafy Vegetables

Dark green leafy vegetables such as mustard greens, lettuce, kale, chicory, spinach, and chard have an abundance of fiber, folate, and carotenoids. These nutrients may help protect against cancer of the mouth, larynx, pancreas, lung, skin, and stomach.

Protection From an Exotic Spice

Curcumin is the main ingredient in the Indian spice turmeric and a potential cancer fighter. Lab studies show it can suppress the transformation, proliferation, and invasion of cancerous cells for a wide array of cancers

Cooking Methods Matter

How you cook meat can make a difference in how big a cancer risk it poses. Frying, grilling, and broiling meats at very high temperatures causes chemicals to form that may increase cancer risk. Other cooking methods such as stewing, braising, or steaming appear to produce fewer of those chemicals. And when you do stew the meat, remember to add plenty of healthy, protective vegetables

A Berry Medley With a Punch

Strawberries and raspberries have a phytochemical called ellagic acid. This powerful antioxidant may actually fight cancer in several ways at once, including deactivating certain cancer causing substances and slowing the growth of cancer cells.

Blueberries for Health

The potent antioxidants in blueberries may have wide value in supporting our health, starting with cancer. Antioxidants fight cancer by ridding the body of free radicals before they can do their damage to cells. Try topping oatmeal, cold cereal, yogurt, even salad with blueberries to boost your intake of these healthful berries.

Pass on the Sugar

Sugar may not cause cancer directly. But it may displace other nutrient-rich foods that help protect against cancer. And it increases calorie counts, which contributes to overweight and obesity. Excess weight is also a cancer risk. Fruit offers a sweet alternative in a vitamin-rich package.

Don't Rely on Supplements

Vitamins may help protect against cancer. But that's when you get them naturally from food. Both the American Cancer Society and the American Institute for Cancer Research emphasize that getting cancer-fighting nutrients from foods like nuts, fruits, and green leafy vegetables is vastly superior to getting them from supplements. Eating a healthy diet is best.

Does This Cause Cancer?

Artificial Sweeteners

Despite all the talk -- and chain emails -- there’s no proof that these sugar stand-ins raise your risk of cancer. Saccharine did cause cancer in rats, but their bodies react to it differently than ours, researchers say. There hasn’t been a cancer warning label on it since 2000. A study of aspartame in people found no link either.

X-rays

Your dentist covers you in a lead blanket for a reason. Even low doses of X-rays raise your chances of getting cancer, but only by a small amount. In general, the higher the dose of radiation, the more the risk. But there’s no amount of this kind of radiation that’s totally safe. That’s why the EPA limits how much you can get.

Cell Phones

This gadget, which you keep near all the time, gives off the same type of energy as X-rays. So far, it hasn’t been linked to cancer, but more research is needed. Just to be safe:
  • Save it for short chats or when there’s no landline.
  • Use a hands-free device.

Meat

Whether it’s processed or red, you need less of it in your life. Just one hot dog a day could boost your chances of getting colon cancer.  Luncheon meats, cold cuts, and hot dogs all have preservatives called nitrites, which cause cancer. Smoking meats or cooking them at a high temperature creates compounds called PAHs. Studies are under way to see how they affect people.

Bottled Water

If your bottle is clear plastic, it probably has bisphenol A (BPA). This chemical is used in food and drink containers, dental sealants, and other products. Does it cause cancer? The FDA says no, BPA is safe at current levels found in foods. If you’re concerned, avoid canned foods and store chow and drinks in clear plastic. For hot food, use glass or steel instead. 

Sex

It’s true. Human papillomavirus (HPV), the most common sexually transmitted infection, can cause cervical and other cancers. Most adults who have sex will get this virus at some point. But they won’t all get cancer. Most of the time, HPV goes away by itself. To lower your risk:
  • Get vaccinated if you’re a female aged 11-26 or a male aged 11-21.
  • Use condoms during sex.
  • Have sex with only one partner.

Dental Fillings

Don’t call the dentist to have your metal filings removed and replaced. Experts say your current ones are safe. Studies have found no link between fillings with mercury and cancer -- or any other disease.

Coffee

If you feel your day doesn’t really start until you’ve had a shot of caffeine, you’ll love this. New research shows that drinking moderate amounts of coffee (around four cups daily) lessens the risk of some types of cancer, among them skin, liver, and colon.

Deodorant and Antiperspirant

Scientists say more research is needed to know for sure if these products boost the odds of breast cancer. They have different jobs -- deodorant blocks the smell and antiperspirant stops sweat. Many use chemicals that act like the hormone estrogen, which causes cancer cells to grow. These include benzylparaben, butylparaben, methylparaben, and propylparaben.

Fluoride

This compound is found in water and other drinks and in food, toothpastes, and mouth rinses. Though many studies have looked for links between it and cancer, most researchers says there’s no strong tie. If you’re worried about it, you can ask the Environmental Protection Agency how much is in your drinking water. If it’s high, switch to bottled spring water, which usually has the least.

Household Products

Many pesticides, paints, varnishes, and waxes give off gases known as volatile organic compounds  (VOCs). So do some cleaning, cosmetic, automotive, and hobby products. These gases have been linked to cancer in humans and animals. To cut your risk choose products labeled low-VOC and biodegradable when possible. Avoid items labeled as: 
  • Danger/Poison
  • Corrosive
  • Severely Irritating
  • Highly Flammable
  • Highly Combustible
  • Strong Sensitizer 

Power Lines

Anything that makes, sends, or uses electricity gives off extremely low frequency (ELF) radiation. There’s no proof that it causes cancer. Still, the National Institute of Environmental Health Sciences says there’s cause for “limited concern.” To be safe, stay at least an arm’s length away from electrical devices. If you live close to a power line and you're worried, get a gizmo called a gaussmeter. You can use it to measure the ELF fields near you.

Pollution

Air pollution causes over 220,000 lung cancer deaths worldwide a year (most of them in Asia). There’s also a link between dirty air and a higher risk of bladder cancer. But the odds for any one person are low. To cut your chances, listen to local smog alerts. Try to stay inside on days when the air quality is poor.

4 Vitamins and Minerals for Adults



Are you getting enough of the nutrients you need? You might be surprised. Many adults don't.
Four nutrients were singled out as "of concern" in the 2010 Dietary Guidelines for Americans because a lot of people aren't getting enough of them.
Are you one of them? Find out what you may be missing out on, how much you need, and how to get it.

1. Potassium

You may not hear as much about potassium as you do other nutrients, like calcium and vitamin C. But potassium is essential to managing blood pressure.
Sodium raises your blood pressure. Potassium lowers it.
"It also may improve problems with kidney stones and bone loss," says Andrea Giancoli, MPH, RD. She's a spokeswoman for the Academy of Nutrition and Dietetics.
How much you need: For most adults, the recommended daily amount is 4,700 milligrams (mg).
How to get it: The single best food source of potassium is the potato.
"A small potato has about 740 mg of potassium," Giancoli says.
Other good potassium sources include juices such as:
  • Prune
  • Carrot
  • Orange
  • Tomato
Also try eating beans, especially these types:
  • White
  • Lima
  • Soy
You can also get potassium in some fish, such as:
  • Halibut
  • Tuna
  • Cod
Potassium is also found in dairy products such as milk and yogurt.

2. Vitamin D

We cover up with hats, slather on sunscreen, and stay indoors to help prevent skin cancer. One unintended side effect of all this sun protection is that some people -- about 20% of the population, it's estimated -- are low in the "sunshine vitamin," vitamin DVitamin D works with calcium to build bone strength.
How much you need: Most adults should get 600 IU of vitamin D per day. For adults over 70, the recommendation is 800 IU.
How to get it: Large doses of vitamin D aren't naturally found in too many foods, Giancoli says.
"You can find some in fatty fish like salmon, tuna, and sardines," she says. "It's also found in egg yolks. So if you eat only the egg whites, you may miss a good source of vitamin D."
Milk and orange juice, especially fortified varieties, are also good sources of vitamin D. Another surprising source: mushrooms that are grown in the sunlight.
"You can find packaged mushrooms now that advertise 100% of the daily value of vitamin D," Giancoli says.

3. Calcium

All adults need calcium. Without enough calcium, we risk osteoporosis and bone fractures. But calcium builds more than just bones. It's also important to our nerves and muscles.
How much you need: All adults aged 19 to 50 should get 1,000 mg of calcium daily. The requirement goes up to 1,200 mg a day for women over 50 and for all adults over 70.
How to get it: Dairy products such as milk and yogurt are sources of calcium. But Giancoli says that many non-dairy milks, such as soy and almond milk, are now often fortified with calcium.
Many brands of orange juice are also fortified with calcium. Check the label.
Salmon, kale, turnip greens, and some kinds of tofu are other good dietary sources of calcium.

4. Fiber

Fiber in foods helps your digestive system and may lower your risk of heart disease and diabetes. But the average American diet isn't rich in fiber.
How much you need: Women should get 25 grams of fiber per day, and men 38 grams a day, but most people only get about 15 grams.
How to get it: Beans! Legumes are some of the best sources of dietary fiber. Some beans you can try:
  • Navy
  • White
  • Lima
  • Pinto
  • Black
Most vegetables and fruits are also good fiber sources. So are whole-grain breads and pastas.
