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.

Ulcerative Colitis Advice

On my earlier post Best of the Web: Ulcerative Colitis, I listed a few websites recommended by health professionals. Now I would like to say that I also like the University of Maryland writeup.

Here are the main lifestyle suggestions I found on these websites:

1) Exercise. And note that endurance exercise, such as long-distance running and hiking, can help suppress your overactive immune system.

2) Avoid stress.

3) Avoid milk products, including whey protein. (But make sure to supplement your diet with calcium and vitamin D. Take 1000 mg to 1250 mg of calcium each day, plus vitamin D.)

Egg white protein powder is usually OK (but make sure that it does not contain powdered egg yolks).

4) Don’t eat foods that bother you, period.

5) Stay on a low fat diet.

6) Eat lots of vegetables and fruits.

7) If vegetables and fruits bother you, cook them.

And I would add a few additional pointers:

1) Stay away from most fresh vegetables and fruits. Eat frozen produce. Those fresh, unfrozen vegetables you see in the produce section of your local supermarket/grocery have had plenty of time to grow molds and bacteria, both while on the shelf and while in route to the store. And all those germs and fungi will provoke your immune system. (See A Fish and Vegetable Diet.)

Try to buy products grown in the United States, Europe, and Canada.

2) Avoid all grains. (But you might want to try Quinoa.) Do not eat granola!

3) Do not eat red meat. Eat fish and egg whites. (Do not eat egg yolks!)

4) Do not eat at restaurants.

5) Do not eat processed food (meals, meats, snacks, frozen dinners, cereals, etc.).

6) Fix your own meals. Don’t trust other people to make your meals for you.

7) Take tumeric every day, that is, take it at your own risk. (See Frontier Turmeric Root Ground and New Chapter Tumericforce. But if the New Chapter Tumericforce begins to irritate your digestive system or cause you pain, then discontinue for a month and then start again if you think you can.)

8 ) Take a good, pharmaceutical-grade fish oil every day, that is, take it at your own risk. (I only recommend Nordic Naturals – Ultimate Omega and Ascenta, Nutra Sea HP Fish Oil. Take one to two grams a day and make sure that it does not thin your blood too much: See Colitis, Fish Oil, Chocolate, Tea and Spices.)

9) Get out for a hike or walk every day, or use the treadmill.

10) Do not eat whole nuts and seeds. Eat nut butters and seed butters.

11) Do not take alfalfa or zinc (or supplements that contain alfalfa or zinc). They boost your immune system. You want to stay away from immune-boosting herbs, such as echinacea.

12) Eat the right oils.

13) Read Dr. Sears’ The Anti-Inflammation Zone: Reversing the Silent Epidemic That’s Destroying Our Health. He tells you how to balance good proteins, carbohydrates, and fats, and shows you that it is important to avoid grains. (But note that some of his suggestions will thin your blood; see Colitis, Fish Oil, Chocolate, Tea and Spices).

14) Get plenty of rest. Do not overwork yourself. Take time off. Relax.

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:

California Indoor Quality Program

Hazardous Ozone-Generating ‘Air Purifiers’

Ozone Generator Fact Sheet

American Lung Association

Environmental Protection Agency (EPA): Air Cleaners

National Institutes of Health: Ozone.

Avoiding BPA in Plastic

For a good article on plastics and BPA (Bisphenol A), see this National Wildlife Federation Article. The authors identify the plastic products that contain BPA and they tell you how avoid them.

Beware of Advice from Meetup.com Members

If you join a Meetup.com activity, let’s say a hiking group, and you hear the members giving out impromptu advice regarding survival, health, injury, etc., make sure you consult a professional, too, or at least do some reading.

You might find that at a monthly hikers’ meeting, an attractive know-it-all is showing you a stretching exercise for your sore knee. But if you go to a good physiotherapist, you might learn that the stretching will only exacerbate your knee or hip injury, that what you really need to do is build muscle strength in the injured area.

Similarly, someone might tell you that no one dies from rattlesnake bites and that the Mojave Rattler is no more dangerous than a Diamondback. However, if you take the time to read page 583 in A Natural History of the Sonoran Desert (Arizona-Sonora Desert Museum) you will find that world-renowned experts write, “The Mojave has a very toxic venom that has caused human fatalities.”

Here’s couple of good (but brief) desert survival books:

Tart Cherries May Help Sleep

AOL Travel has an interesting short article about how tart cherries may help fight jet lag. The cherries contain small amounts of melatonin, a hormone that co-regulates sleep patterns.

Calcium

If you are unable to eat milk products or if you are taking a medication such as prednisone, you should definitely take calcium supplements — at least 1000 mg of calcium per day, divided into 2 to 4 doses. Never take more that 500 mg of calcium at one sitting during the day: your body has a hard time utilizing more that 500 mg at a time. And I have heard that among people supplementing with calcium, cranberry juice causes kidney stones. So avoid cranberries.

You might want to take a look at EZorbOnline.com. EZorb is a “new generation” calcium supplement — it has a very high absorption rate. I believe that I can feel the effects of EZorb on my muscle tone and skeletal strength.

The manufacturer states that “EZorb does not need participation of Vitamin D or magnesium for better calcium absorption,” but I still take 1000 IU of Vitamin D every day, and I continue to include old-style calcium-magnesium-zinc supplements in my daily regimen.

Recent research shows that while supplementing with calcium, you should take 1000 IU of Vitamin D every day. The old standard was 400 IU, but now it’s 1000 IU.

Great Resource on Herbs and Alternative Medicine

The University of Maryland Medical Center is one of the very best online references for finding out about herbs. The site comes with a variety of cross-reference tools: Conditions by Organ and Body System, Interactions by Drug, Conditions by Signs and Symptoms, Interactions by Herb or Supplement, Herbs & Supplements by Uses, and Depletions by Drug.

Desert Venom

Although a number of medical professionals still recommend applying a tourniquet to rattlesnake bites (and then briefly releasing the tourniquet every 15 to 20 minutes), Tony Nester, the author of Desert Survival Tips, Tricks, & Skills (Flagstaff: Diamond Creek Press, 2003), writes that most of the doctors he spoke to advise against applying a tourniquet (it simply concentrates the venom in the tissues immediately adjacent to the bite) and that your best treatment is to get to a hospital or clinic as quickly as possible: do not delay.

Nester says that two important rules of desert living are 1) “Don’t put your hands where you can’t see” and 2) “Vigorously slam your boots on the ground and shake clothes before you put them on.”

Watch out for Gila Monsters, Africanized Bees (Killer Bees), Black Widow Spiders, Scorpions, Rattlesnakes, and Coral Snakes.
