Folic Acid Might Promote Cancers of the Breast, Lung, and Colon

On page 59 in his book Crohn’s and Colitis: Understanding the Facts About IBD (1st edition, 20 April 2006), Dr. Hillary Steinhart (a leading Canadian physician and medical professor) states that the vitamin supplement folic acid might reduce the risk of cancer but that the evidence for this possible benefit is not conclusive. Data gathered during a large Nurses’ Health Study, 1980 to 1994, is one of the main sources for evidence supporting the use of folic acid to prevent colon cancer.

Now our scientists and news media are telling us that supplementation with folic acid might increase the risk of cancer, especially colon cancer, breast cancer and lung cancer. The May 2009 issue of Reader’s Digest presses the point that too little folate in the diet can increase the risk of cancer, while too much folic acid can also increase that risk. Folate is the natural form of the vitamin folic acid.

For additional information about the dangers of folic acid supplementation, see Laura Beil’s article “Is your breakfast giving you cancer?” in Prevention Magazine and the CBS News article “High Doses Of Folic Acid May Lead To Colon Cancer.” And also note that on page 103 in the 1st edition of his book Crohn’s and Colitis: Understanding the Facts About IBD, Dr. Hillary Steinhart points out that the prescription drug sulfasalazine “interferes with folate’s metabolism.” He says that if you are taking sulfasalazine, you will probably need to take a folic acid supplement.

I hope Dr. Steinhart brings out a new edition of his book soon. In the meantime, eat plenty of oranges and greens.

They Say Vegetables Don’t Stop Cancer. I Don’t Believe It.

This week the media told us all that a new study shows that eating lots of vegetables does not “significantly” lower cancer risk. (The study indicates that vegetables might provide a very small reduction in cancer risk, but that statistic may have resulted from reporting error and bias — see Eating Vegetables Doesn’t Stop Cancer: http://well.blogs.nytimes.com/2010/04/08/eating-vegetables-doesnt-stop-cancer/.)

The cancer researchers had 142,605 men and 335,873 women report on their eating habits and lifestyles during 1992 to 2000. They then assessed the association between cancer risk and diets high in fruits and vegetables.

But it looks to me that investigating the question “Does eating five or more fruits and vegetables stop cancer?” is like asking “Does taking five or more prescription pills stop cancer?” Obviously, I would not eat a random assortment of pills as a cancer-prevention strategy (nor would I take the over-the-counter pills that happen to be on sale each week).

I drink green tea and eat lots of garlic, tomatoes, apples, berries, greens, and cruciferous vegetables (cabbage, broccoli, cauliflower, and Broccolive). Then I include a very large variety of different fruits and vegetables in my diet, and to that end I also take powered fruits and vegetables and extracts (but I don’t take just one product day after day, month after month, year after year; I rotate them): Rainbow Vibrance Super Food, Progressive Nutritional PhytoBerry, and Drinkables Liquid Fruits and Vegetables Dietary Supplement, for example.

Research on the cancer-prevention properties of fruits and vegetables continues: On January 11, 2010, Texas AgriLife Research food scientists reported that mango prevents or stops colon and breast cancer cells in the laboratory. And at least one researcher at the Arizona Cancer Center in Tucson says a “vegetable-rich diet may avert some cancers,” especially a diet full of cruciferous vegetables: cauliflower, cabbage, kohlrabi, radishes, broccoli, and Brussels sprouts.

Dangerous Household Ozone Generators

Last month I looked up information about in-home ozone generators. A friend of mine was thinking of buying a house in Arizona (she bought it), and the sellers were using indoor ozone generators. The ozone gave my friend a severe headache and caused her blood pressure to rise to dangerous levels. (She takes blood-pressure medication and had to increase the dosage after inspecting the house.)

I rushed to my computer and found quite a few useful websites, and, yes, ozone causes headaches, high blood pressure, sore throats and coughs (see Effects of Ozone Pollution on Seniors and Ozone Generators May Be Dangerous to Your Health). Ozone irritates the lungs, exacerbates lung disease, accelerates aging, and damages home electronics and wiring. In combination with air fresheners or household disinfectants, ozone will produce formaldehyde, a chemical that can cause cancer (see Study Warns of Cleaning Product Risks). The California Department of Health Services began warning consumers about indoor ozone generators back in the 1990s. And Health Canada says, “If you have an ozone generator in your home, stop using it.”

Take a look at these web pages, too:

BPA-free Biodegradable Plastic Bottles

We hear about how plastic bottles are filling our landfills and oceans, but bottled water manufacturers and consumers can solve this problem. We do have biodegradable choices, and biodegradable plastic may cost us a little more in the short term, but I’m sure the costs will fall in the future, as our health and our planet’s health improve.

See www.biogreenbottles.com and BioGreen Biodegradable BPA-Free Sport Bottle with Wide Mouth DuoFlow Lid (26-Ounce). These bottles are BPA, DEHA and DEHP Free, and they are made in the USA.

Tell the bottled water industry that we insist on safe biodegradable plastic.

More About Running and Aerobics

You should try to run at 7 miles per hour for 20 minutes–it gets your heart rate up and provides both cardiovascular and respiratory benefits. I run at the gym on treadmills. The treadmills are equipped with shock absorbers and are generally easier on my joints. You can vary the treadmill speed and slant (elevation) in order to minimize the chance of injury due to repeated motion.

If your joints are not up to running, get on the recumbent bike for a half hour or use the elliptical machine. The recumbent bike is the one where your legs are positioned further out in front of you.

You can also exercise in a swimming pool. The buoyancy takes the weight and wear and tear off your joints. (But I don’t like the chlorine.)

I run 3 times a week and walk for 30 minutes to an hour 3 or 4 times a week, that is, I get some form of aerobic exercise 6 or 7 days a week. And I take calcium (and viatamin D) for my bones and a glucosamine-chondroitin-boron complex for my joints.

More About Cancer Prevention

In addition to my Anti-cancer Diet and Vitamin D, I work out at the gym 3 days a week and take walks and/or lift weights at home 3 to 4 days a week. At the gym, I run 2 miles and then lift weights for an additional 60 to 90 minutes.

I also take numerous 6- to 9-hour hikes up mountains and into canyons, sometimes for 7 days in a row. The hiking may help ward off colon cancer, and I am a firm believer that running helps stave off lung cancer.

My Anti-Cancer Diet

Also see my post Cancer Prevention Foods and Spices. And search the United States government’s National Center for Complementary and Alternative Medicine web site and Mayo Clinc.

Daily anti-cancer foods and supplements:

1) I bought one pound of Organic Connections beet powder for $23.80. (That’s the best price I found).

– I take 1 tsp. of beet powder a day in a shake.

2) I bought one pound of Frontier brand organic turmeric powder for $11.80. (I shopped around and that’s the best price I found. You might get Organic Connections turmeric even cheaper.)

– I take 1 heaping teaspoon of turmeric powder a day in a shake.

3) I eat one ounce (28 to 30 grams) of dark chocolate every day. It has to be 70% or better. I most often eat 85%. But do not take it with milk. Milk inactivates the good ingredients in chocolate.

4) I have about 1/2 to 1 cup of fresh cabbage juice every day.

5) I eat spinach every day.

6) I eat cherries every day.

7) I drink a mug of green tea steeped for 15 minutes every day. You have to steep it for 15 minutes to get the most from it.

8 ) I try to eat a red apple almost every day.

9) I eat broccoli or cauliflower most days.

10) The only powdered “greens” I recommend in Canada is Progressive Nutritional PhytoBerry. It does not have the herbs and alfalfa found in many greens products these days. You should be able to purchase 900 grams (60 servings) of Progressive Phytoberry for $57 to $60. Shop around–the price varies. I like it a lot and have it 3 to 6 times a week.

When I am not taking PhytoBerry, I use Rainbow Vibrance Super Food

11) I take pharmaceutical grade fish oil, usually Nordic Naturals Ultimate Omega or Ascenta Nutra Sea HP.

Cancer Prevention Foods and Spices

As part of your cancer prevention diet consume dark chocolate, cabbage juice, homemade tomato sauce, pharmaceutical grade fish oil, green tea, turmeric, and ginger every day. But don’t overdo it: fish oil, turmeric, ginger, green tea, garlic and cinnamon thin the blood. When you thin the blood too much, you are susceptible to hemorrhagic strokes and other serious health problems. If you already take prescription blood thinners (such as warfarin), you should talk to your doctor about using fish oil, turmeric, ginger, green tea, garlic and cinnamon as health supplements.

Your dark chocolate should be at least 70% cocoa and you should consume 1 ounce (about 30 grams) each day. Eating more than an ounce a day will add to your fat load and make you gain weight.

You should be sure that your fish oil is pharmaceutical grade. Lower quality fish oil products contain contaminants. I take Nordic Naturals Ultimate Omega and Ascenta, Nutra Sea HP fish oil. From what I have read, Dr. Sears and Dr. Weil also market quality fish oil.

My homemade tomato sauce consists of strained Italian tomatoes (from the bottle) slightly simmered with Italian spices. Cooking tomatoes makes the lycopene antioxidant more accessible.

I make cabbage juice every day and drink it immediately after preparing it. I also include a heaping teaspoon of organic turmeric, a half teaspoon of organic powdered ginger, one ounce of 80% – 90% dark chocolate, a mug of green tea (steeped for 15 minutes), and Nordic Naturals fish oil in my daily regimen.

Take turmeric and powdered ginger the easy way: put them in a protein shake at lunch.

Signs of Ovarian Cancer – Important Information

This e-mail was forwarded to me:

> MUST TO READ TO THE END. . . .

Basically, it was a new form of a discredited e-mail that has been circulating for years. Its main thrust is that you must have regular CA-125 blood tests. However, quite a few Web sites cast doubt on this e-mail’s story/testimonial. Take a look at Trend Micro’s summary at Hoaxes.

And also see the Urban Legends synopsis: http://www.snopes.com/medical/disease/ca125.asp.

More importantly, John Hopkins University, in its Questions and Answers About the CA-125 Test, says,

The CA-125 test is not recommended for use alone as an early detection method. The rate of false positives is very high, and there has been no data concerning change in mortality.

Cabbage Cures?

They say cabbage heals ulcers and prevents cancer. Here is one great site for finding information: The World’s Healthiest Foods: Cabbage.

Some people drink cabbage juice (the fresh juice is sweet, with a bit if an edge). If you buy a good WIDE MOUTHED juicer, the process is quite easy.

Others go on cabbage soup diets, but I am sure that you would want to investigate its health effects, since boiling the cabbage destroys nutrients and since protein is an important component of all healthy dietary regimes.
