Edible Healing: Food Cures for Cancer

Doctor's Orders

How I fought my diagnosis

I was diagnosed with brain cancer about 16 years ago. I received chemotherapy and went into remission, but the cancer came back and I endured two surgeries and 13 months of chemotherapy. I asked my oncologist if I ought to change my diet to avoid another recurrence. His answer was perfectly stereotypical: "Eat what you like. It won't make much difference."
He was wrong.
The extensive research published in the last decade alone proves that what you eat can have a profound effect on your protection against cancer. But my doctor's answer was hardly surprising. It's a little-known fact that nutrition is barely taught in med schools, where the solution to most problems is a drug. And doctors don't trust patients to make lifestyle changes. I recall a conversation with a fellow physician at a conference after I spoke on the importance of a healthy diet in fighting disease. "You may be right, David, but people don't want to change," he said. "They just want to take a pill and forget about it." I don't know whether he's right, but after all the study I've done, I know it isn't true for me

Quest for Change

Discovering cancer-fighting foods

I spent months researching the healing powers of food before I fully grasped my own natural cancer-fighting potential. I met with a variety of researchers, scoured medical databases, and combed scientific publications. I traveled all over the world and consulted experts from nearly every continent.

In my quest, I discovered that the list of anticancer foods is actually quite long. Some foods block natural bodily processes such as inflammation that fuels cancer growth. Others force cancer cells to die through a process that specialists call apoptosis. Still other foods assist the body in detoxifying cancer-causing toxins or protecting against free radicals. But most of them attack the disease on a variety of fronts. And they do it every day, three times a day, without provoking any side effects. To avoid the disease, it's essential to take advantage of this natural protection, and nurture it.

I've learned that the anticancer diet is the exact opposite of the typical American meal: mostly colorful vegetables and legumes, plus unsaturated fats (olive, canola, or flaxseed oils), garlic, herbs, and spices. Meat and eggs are optional. Through extensive research, I devised a list of the most promising cancer fighters, along with recommendations on how to make the most of their potential. Include at least one, and preferably two, at every meal, to maximize your protection.

A Health-Boosting Beverage

Best drinks for bettering your body

Green tea is rich in compounds called polyphenols, including catechins (and particularly EGCG), which reduce the growth of new blood vessels that feed tumors. It's also a powerful antioxidant and detoxifier (activating enzymes in the liver that eliminate toxins from the body), and it encourages cancer cell death. In the laboratory, it has even been shown to increase the effect of radiation on cancer cells.

Japanese green tea (sencha, gyokuro, matcha, etc.) contains more EGCG than common varieties of Chinese green tea, making it the most potent source on the market; look in Asian groceries and tea shops. Black and oolong teas, commonly used to produce popular tea blends such as Earl Grey, are less effective because they've been fermented, which destroys a large proportion of their polyphenols. Decaffeinated green teas, which retain the polyphenols despite the process of decaffeination, are also an option if you're sensitive to caffeine.

How to Drink It: Sip 2 to 3 cups a day within an hour of brewing. Green tea must be steeped for at least 5 to 8 minutes--ideally 10--to release its catechins, but it loses its beneficial polyphenols after an hour or two.

Pomegranate JuiceThis juice, which tastes like raspberries, has been used in Persian medicine for thousands of years. Its antioxidant and anti-inflammatory properties are well confirmed; studies show it can substantially reduce the development of even the most aggressive prostate cancers (among others). In addition, drinking it daily slows the spread of an established prostate cancer by more than 50%.

How to Drink It: Have 8 ounces daily with breakfast.

 

Two Tumor-Tackling Spices

Season liberally for anti-inflammatory benefits

Fresh ginger, or gingerroot, is a powerful anti-inflammatory that combats certain cancer cells and helps slow tumor growth. A ginger infusion can also alleviate nausea from chemotherapy or radiotherapy.

How to Use It: Add grated fresh ginger to a vegetable stir-fry or fruit salad. Or, make an infusion by slicing a 1-inch piece of ginger and steeping it in boiling water for 10 to 15 minutes; drink hot or cold.

TurmericFound in curry powder, this spice is the most powerful natural anti-inflammatory available today. It encourages cancer cell death, inhibits tumor growth, and even enhances the effectiveness of chemotherapy. Some research shows that turmeric is most effective in humans when it's mixed with black pepper and dissolved in oil (olive or canola, preferably). In store-bought curry mixes, turmeric represents only 20% of the total, so it's better to obtain ground turmeric directly from a spice shop.

How to Use It: Mix a teaspoon of turmeric powder with a teaspoon of olive oil and a generous pinch of ground black pepper and add to vegetables, soups, and salad dressings. Use a tablespoon if you already have cancer.

 

Vital Veggies

Stock a cancer-fighting shopping cart

Brussels sprouts, bok choy, Chinese cabbage, broccoli, and cauliflower all contain sulforaphane and indole-3-carbinols (I3Cs), two potent anticancer molecules. These molecules help the body detoxify certain carcinogenic substances and can help prevent precancerous cells from developing into malignant tumors. They also promote the suicide of cancer cells and block tumor growth.

How to Prepare Them: Cover and steam briefly or stir-fry rapidly with a little olive oil. Avoid boiling cabbage and broccoli, which destroys their cancer-fighting compounds.

Garlic, Onions, Leeks, Shallots, ChivesThe sulfur compounds found in this group (the alliaceous family) promote the death of colon, breast, lung, and prostate cancer cells. Epidemiological studies also suggest a lower risk of kidney and prostate cancer in people who consume the most garlic.

How to Eat Them: The active compounds in garlic are released when you crush the clove, and they're much more easily absorbed if they're combined with a small amount of oil. Sauté chopped garlic and onions in a little olive oil, mix with steamed or stir-fried vegetables, and toss with black pepper and turmeric. They can also be consumed raw, mixed in salads, or layered on sandwiches.

 

Proteins for a Better Prognosis

Sub out chicken and meat to prevent disease 

Compounds called isoflavones (including genistein, daidzein, and glycitein) prevent tumor growth and block the stimulation of cancer cells by sex hormones (such as estrogens and testosterone). There are significantly fewer breast cancer cases among Asian women who have eaten soy since adolescence, and when they do have breast cancer, their tumors are usually less aggressive with higher survival rates. Isoflavone supplements (in pill form) have been associated with an aggravation of certain breast cancers, but whole soy, eaten as food, has not.

How to Eat It: Replace conventional milk products with soy milk or soy yogurts for breakfast. Also, use tofu, tempeh, and miso in soups and stir-fries.

Fatty FishThe risk of several cancers is significantly lower in people who eat fish at least twice a week. Several studies discovered that the anti-inflammatory long-chain omega-3s found in fatty fish (or in high-quality purified fish-oil supplements) can help slow cancer cell growth in a large number of tumors (lung, breast, colon, prostate, kidney, etc.).

How to Eat It: Have a seafood-based meal two or three times a week. Choose small fish, such as anchovies, small mackerel, and sardines (including canned sardines, provided they are preserved in olive oil and not in sunflower oil, which is too rich in pro-inflammatory omega-6 fats). Small fish contain fewer environmental toxins such as PCBs and mercury. Wild salmon is also a good source of omega-3 fats, and the level of contamination is still acceptable. Choose fresh over frozen whenever possible, because omega-3 content degrades over time.

 

 

Disease-Fighting Fruits

Fresh and frozen varieties provide year-round protection

Oranges, tangerines, lemons, and grapefruit contain anti-inflammatory compounds called flavonoids that stimulate the detoxification of carcinogens by the liver. Certain flavonoids in the skin of tangerines--tangeritin and nobiletin--can also help promote the death of brain cancer cells.
How to Eat It: Sprinkle grated citrus zest (from organic fruits) into salad dressings or breakfast cereals, or steep in tea or hot water. Eat whole fruits out of hand, toss with other fruits in a salad, or use in a salsa to season grilled fish.
BerriesStrawberries, raspberries, blueberries, blackberries, and cranberries contain ellagic acid and a large number of polyphenols, which inhibit tumor growth. Two polyphenols found in berries, anthocyanidins and proantho­cyanidins, promote cancer cell death.
How to Eat Them: At breakfast, mix fruit with soy milk and multigrain cereals. (The best cereal options combine oats, bran, flaxseed, rye, barley, spelt, and so on.) Frozen berries are just as potent as fresh.

 

Cure It with Dessert

Enjoy antioxidant-rich dark chocolate

Chocolates containing over 70% cocoa provide a number of antioxidants, proanthocyanidins, and many polyphenols. In fact, a square of dark chocolate contains twice as many as a glass of red wine and almost as many as a cup of green tea properly steeped. These molecules slow the growth of cancer cells and limit the blood vessels that feed them.

How to Eat It: Enjoy about one-fifth of a dark chocolate bar a day guilt free. Milk chocolate isn't a good alternative because dairy cancels out the cancer protection of the polyphenol compounds.

To date, there is no alternative approach that can cure cancer, and I believe that the best of conventional medicine--surgery, chemotherapy, radiotherapy, immunotherapy, and soon, molecular genetics--must be used to treat this disease. But to neglect your own natural cancer-fighting capacity is folly. I've kept cancer at bay for 8 years now, and I attribute my survival largely to the changes I've made in my diet and lifestyle. I exercise and meditate more and eat wholesome anticancer foods on a daily basis. Still, the medical establishment is slow to embrace this approach. After my last screening at the university's cancer center, I stopped at the cafeteria and discovered eight different types of tea: Darjeeling, Earl Grey, chamomile, and several fruit-flavored herbal teas. Sadly, there was not a single packet of green tea in the lot.

20 Ways to Prevent Cancer

1. Filter your tap water

You’ll reduce your exposure to known or suspected carcinogens and hormone-disrupting chemicals. A new report from the President’s Cancer Panel on how to reduce exposure to carcinogens suggests that home-filtered tap water is a safer bet than bottled water, whose quality often is not higher—and in some cases is worse—than that of municipal sources, according to a study by the Environmental Working Group. (Consumer Reports’ top picks for faucet-mounted filters: Culligan, Pur Vertical, and the Brita OPFF-100.) Store water in stainless steel or glass to avoid chemical contaminants such as BPA that can leach from plastic bottles. 

2. Stop topping your gas tank

So say the EPA and the President’s Cancer Panel: Pumping one last squirt of gas into your car after the nozzle clicks off can spill fuel and foil the pump’s vapor recovery system, designed to keep toxic chemicals such as cancer-causing benzene out of the air, where they can come in contact with your skin or get into your lungs.

3. Marinate meat before grilling

Processed, charred, and well-done meats can contain cancer-causing heterocyclic amines, which form when meat is seared at high temperatures, and polycyclic aromatic hydrocarbons, which get into food when it’s charcoal broiled. “The recommendation to cut down on grilled meat has really solid scientific evidence behind it,” says Cheryl Lyn Walker, PhD, a professor of carcinogenesis at the University of Texas M.D. Anderson Cancer Center. If you do grill, add rosemary and thyme to your favorite marinade and soak meat for at least an hour before cooking. The antioxidant-rich spices can cut HCAs by as much as 87%, according to research at Kansas State University. 

4. Caffeinate every day

Java lovers who drank 5 or more cups of caffeinated coffee a day had a 40% decreased risk of brain cancer, compared with people who drank the least, in a 2010 British study. A 5-cup-a-day coffee habit reduces risks of oral and throat cancer almost as much. Researchers credit the caffeine: Decaf had no comparable effect. But coffee was a more potent protector against these cancers than tea, which the British researchers said also offered protection against brain cancer. 

5. Water down your cancer risk

Drinking plenty of water and other liquids may reduce the risk of bladder cancer by diluting the concentration of cancer-causing agents in urine and helping to flush them through the bladder faster. Drink at least 8 cups of liquid a day, suggests the American Cancer Society. 

6. Load up on really green greens

Next time you’re choosing salad fixings, reach for the darkest varieties. The chlorophyll that gives them their color is loaded with magnesium, which some large studies have found lowers the risk of colon cancer in women. “Magnesium affects signaling in cells, and without the right amount, cells may do things like divide and replicate when they shouldn’t,” says Walker. Just 1/2 cup of cooked spinach provides 75 mg of magnesium, 20% of the daily value. 

7. Snack on Brazil nuts

They’re a stellar source of selenium, an antioxidant that lowers the risk of bladder cancer in women, according to research from Dartmouth Medical School. Other studies have found that people with high blood levels of selenium have lower rates of dying of lung cancer and colorectal cancer. Researchers think selenium not only protects cells from free radical damage but also may enhance immune function and suppress formation of blood vessels that nourish tumors.

8. Burn off your breast cancer risk

Moderate exercise such as brisk walking 2 hours a week cuts risk of breast cancer 18%. Regular workouts may lower your risks by helping you burn fat, which otherwise produces its own estrogen, a known contributor to breast cancer.

9. Skip the dry cleaner

A solvent known as perc (short for perchloroethylene) that’s used in traditional dry cleaning may cause liver and kidney cancers and leukemia, according to an EPA finding backed in early 2010 by the National Academies of Science. The main dangers are to workers who handle chemicals or treated clothes using older machines, although experts have not concluded that consumers are also at increased cancer risk. Less toxic alternatives: Hand-wash clothes with mild soap and air-dry them, spot cleaning if necessary with white vinegar. 

10. Ask your doc about breast density

Women whose mammograms have revealed breast density readings of 75% or more have a breast cancer risk 4 to 5 times higher than that of women with low density scores, according to recent research. One theory is that denser breasts result from higher levels of estrogen—making exercise particularly important (see #8). “Shrinking your body fat also changes growth factors, signaling proteins such as adipokines and hormones like insulin in ways that tend to turn off cancer-promoting processes in cells,” Walker says. 

11. Head off cell phone risks

Use your cell phone only for short calls or texts, or use a hands-free device that keeps the phone—and the radio frequency energy it emits—away from your head. The point is more to preempt any risk than to protect against a proven danger: Evidence that cell phones increase brain cancer risk is “neither consistent nor conclusive,” says the President’s Cancer Panel report. But a number of review studies suggest there’s a link.

12. Block skin cancer with color

Choosing your outdoor outfit wisely may help protect against skin cancer, say Spanish scientists. In their research, blue and red fabrics offered significantly better protection against the sun’s UV rays than white and yellow ones did. Don’t forget to put on a hat: Though melanoma can appear anywhere on the body, it’s more common in areas the sun hits, and researchers at the University of North Carolina at Chapel Hill have found that people with melanomas on the scalp or neck die at almost twice the rate of people with the cancer on other areas of the body. 

13. Pick a doc with a past

Experience—lots of it—is critical when it comes to accurately reading mammograms. A study from the University of California, San Francisco, found that doctors with at least 25 years' experience were more accurate at interpreting images and less likely to give false positives. Ask about your radiologist's track record. If she is freshly minted or doesn't check a high volume of mammograms, get a second read from someone with more mileage. 

14. Eat clean foods

The President’s Cancer Panel recommends buying meat free of antibiotics and added hormones, which are suspected of causing endocrine problems, including cancer. The report also advises that you purchase produce grown without pesticides and wash conventionally grown food thoroughly to remove residues. (The foods with the most pesticides: celery, peaches, strawberries, apples, and blueberries. See the full list of dirtiest fruits and vegetables here.) “At least 40 known carcinogens are found in pesticides and we should absolutely try to reduce exposure,” Sellers says. 

15. Read food labels for folic acid

The B vitamin, essential for women who may become or are pregnant to prevent birth defects, is a double-edged sword when it comes to cancer risk. Consuming too much of the synthetic form (not folate, found in leafy green veggies, orange juice, and other foods) has been linked to increased colon cancer risk, as well as higher lung cancer and prostate cancer risks. Rethink your multivitamin, especially if you eat a lot of cereal and fortified foods. A recent CDC study discovered that half of supplement users who took supplements with more than 400 mcg of folic acid exceeded 1,000 mcg per day of folic acid. Most supplements pack 400 mcg. Individual supplements (of vitamin D and calcium, for instance) may be a smarter choice for most women who aren’t thinking of having kids. 

 

16. Up your calcium intake

Milk's main claim to fame may also help protect you from colon cancer. Those who took calcium faithfully for 4 years had a 36% reduction in the development of new precancerous colon polyps 5 years after the study had ended, revealed Dartmouth Medical School researchers. (They tracked 822 people who took either 1,200 mg of calcium every day or a placebo.) Though the study was not on milk itself, you can get the same amount of calcium in three 8-ounce glasses of fat-free milk, along with an 8-ounce serving of yogurt or a 2- to 3-ounce serving of low-fat cheese daily.

 

17. Commit to whole grains

You know whole wheat is better for you than white bread. Here’s more proof why you should switch once and for all: If you eat a lot of things with a high glycemic load—a measurement of how quickly food raises your blood sugar—you may run a higher risk of colorectal cancer than women who eat low-glycemic-load foods, found a Harvard Medical School study involving 38,000 women. The problem eats are mostly white: white bread, pasta, potatoes, and sugary pastries. The low-glycemic-load stuff comes with fiber.

18. Pay attention to pain

If you’re experiencing a bloated belly, pelvic pain, and an urgent need to urinate, see your doctor. These symptoms may signal ovarian cancer, particularly if they're severe and frequent. Women and physicians often ignore these symptoms, and that's the very reason that this disease can be deadly. When caught early, before cancer has spread outside the ovary, the relative 5-year survival rate for ovarian cancer is a jaw-dropping 90 to 95%.

19. Avoid unnecessary scans

CT scans are a great diagnostic tool, but they deliver much more radiation than x-rays and may be overused, says Barton Kamen, MD, PhD, chief medical officer for the Leukemia & Lymphoma Society. In fact, researchers suggest that one-third of CT scans could be unnecessary. High doses of radiation can trigger leukemia, so make sure scans are not repeated if you see multiple doctors, and ask if another test, such as an ultrasound or MRI, could substitute. 

20. Drop 10 pounds

Being overweight or obese accounts for 20% of all cancer deaths among women and 14% among men, notes the American Cancer Society. (You're overweight if your body mass index is between 25 and 29.9; you're obese if it's 30 or more. Click here to gauge your BMI.) Plus, losing excess pounds reduces the body's production of female hormones, which may protect against breast cancer, endometrial cancer, and ovarian cancer. Even if you're not technically overweight, gaining just 10 pounds after the age of 30 increases your risk of developing breast, pancreatic, and cervical, among other cancers.
