"Yes, Virginia, there is a Satan (cancer) clause" Naturally Speaking by Christopher C. Barr

More than a decade ago a Christmas Day message of cheer and hope disclosed the brightest light against cancer ever found with the mineral selenium—a nutrient called a trace element due to being needed in such a tiny amount. The story made the front page on newspapers across America.


Worse-than-Grinch groups are trying to grab that treat with a dastardly trick just in time for Halloween this year.


The National Cancer Institute has made its official pronouncement in conjunction with others that selenium supplements do not benefit the prostate.


We do not recommend supplements”, said Dr. Peter Greenwald after the phenomenal success of the selenium study of the 1990s. Greenwald was then as now director of the National Cancer Institute’s (NCI) Division of Cancer Prevention and Control.


Yes, the man in charge of cancer prevention studies for the United States has a predetermined bias against nutrition supplements.


“We do not recommend supplements” is the Satan clause.


Where there’s a will there’s a way


The first action of NCI was inaction. They tried to ignore selenium hoping the subject would go away (ignorance has been a primary part of the NCI for decades).


Selenium continued to get attention for its cancer prevention possibilities so NCI took an old page from its anti-nutrient playbook.


Decades ago a strong link was established for high levels of the nutrient beta carotene in food against lung cancer in a long term study.


A second study was set up – and set up is the operative phrase here—but a man-made, synthesized form of beta carotene was used rather than a 100 per cent whole food form of beta carotene.


There is a difference – and you’re body knows the difference – between 100 per cent whole food nutrients and man-made, synthetic varieties of nutrients (so-called).


Man-made forms of nutrients look different under the microscope than the forms that are grown in food – formed only as The Almighty can form them through (and with) life.


Man-made forms of nutrients also act differently than the 100 per cent whole food nutrients.


Nutrients formed through life processes are always superior to those made by man. Usually there is a significant difference. Sometimes the difference is small. On occasion the man-made variety may even cause harm.


The beta carotene study that utilized the man-made variety was stopped early because preliminary results revealed a notable increase in lung cancer among those taking it rather than a decrease in lung cancer as had been noted in the study with dietary beta carotene.


The experts (so called) determined that beta carotene could be dangerous as it increased lung cancer. If that were the case then healthful eating habits would be comparable to cigarette smoking for cancer risk.


The facts of the matter were that synthetic beta carotene was the problem and not the actual nutrient beta carotene. Tragically, man-made varieties of nutrients make up the vast majority of all supplements in the marketplace.


The NCI concocted a selenium study using a man-made variety of selenium rather than using a 100 per cent whole food selenium such as that which demonstrated the tremendous success of the previous study.


The form of selenium used by NCI has been found to have a very insignificant antioxidant activity – especially when compared to 100 per cent whole food selenium such as was used in the successful study.


High dose use of vitamin E was also added to this study. One of the first things I learned in my selenium studies dating back to the 1970s was that if it was combined with high dose vitamin E usage then the antioxidant activity of the selenium was greatly reduced.


So this new NCI study utilized a variety of selenium with low antioxidant activity that was then mixed with high dose vitamin E which further diminishes antioxidant activity of selenium.


Oh, and the vitamin E used was a man-made, synthetic variety.

The new study was reported this week as stopped years short of completion because no positive benefit had been seen. However, benefits are not likely to show up in a short period of time.


There are many other deficiencies in this latest study. I’ve seen less holes in Swiss cheese than in this NCI prostate cancer study with selenium and vitamin E.


Call me ‘Prophet’


Ever since the new NCI selenium (and vitamin E) study was started only a few years ago I have said you don’t have to wait for results of this one. I could already tell you that they were not going to have the success of the previous study due to poor quality supplements and poor study design. The only way this study was well designed was for failure.


Also, I had noted that I wouldn’t be surprised if they somehow ascribed some harm from selenium.


Sure enough the NCI noted a very small increase in diabetes among those using selenium though they admitted it was so small a difference as to be inconsequential and “may be due to chance”. Yet they hung the suspicion out very prominently.


Yup, call me ‘Prophet’.


Tangled web


The very successful selenium cancer study of more than a decade ago was dismissed by Dr. Peter Greenwald who noted multiple studies of selenium and cancer would be necessary before coming to any conclusions. Yet he is now satisfied to conclude selenium is of no value after only ONE other study – and an exceedingly flawed study at that.


A drug, finasteride (Proscar/Propecia) was noted to still be able to reduce prostate cancer incidence though it was noted that side effects limit its use.

What was not noted is that the side effects include loss of prostate functions, greater amounts of more aggressive prostate cancers and even death.


OOPS!


With friends like Dr. Peter Greenwald and his NCI cohorts who needs enemies?

Yes, Virginia, Dr. Peter Greenwald’s “We do not recommend supplements” is the Satan clause.

"Wedded Bliss, Ignorant Bliss" Christopher C. Barr's 2002 Selenium Counterpunch to "Stand Up To Cancer"

You’ve heard about those who are "married to the job"? This is because of such devotion to the job that it seems to take up all their time.

Researchers can be like this. They can also get caught up in the chase more than in capturing the prize.

Something old

President Richard Nixon issued a directive in 1971 announcing ‘War on Cancer’. This declaration of war was issued to make curing cancer the top priority for America. The stated intent was for such a cancer cure to come about by the bicentennial of America 5 years later.

Cancer specialist Dr. Albert Braverman wrote 20 years later that not one, single, incurable cancer after the ‘War on Cancer’ began had become curable.

Annual cancer diagnoses and deaths now exceed those of 1971 some 30 years after the ‘War on Cancer’ was declared.

Older still, in 1949 Drs. Clayton and Baumann wrote in the journal Cancer Research (vol. 9, pp. 575-582) that the trace mineral element selenium reduced cancer incidence by one-third.

Oldest yet is that selenium was first put forth as a possible preventative against cancer in 1912.

Something new

Federal health officials last month announced "the largest prostate cancer prevention trial that's ever been performed" according to Dr. Leslie Ford of the National Cancer Institute (NCI). The NCI is under the National Institutes of Health that is part of the United States government.

This new cancer prevention trial is to be a twelve-year study. The study is to involve more than 30,000 men. Part of the investigation is designed to use selenium.

Something borrowed

On Christmas morning of 1996 a front-page cover story appeared in the Los Angeles Times and other newspapers across the country. A large, university study on cancer demonstrated that selenium prevented cancer and also increased survival time for those who came down with this condition.

The study included the finding of a 63% reduction in prostate cancer among those taking a 200 microgram supplement of organic selenium.

The study was conducted by an associate professor at a major university cancer center. The professor’s name was Dr. Larry Clark.

Something blue

The name of Dr. Larry Clark rang a bell with me that early winter morning when this story broke.

I remembered a Larry Clark from Cornell University that had co-authored an article more than a decade earlier in Nutrition Reviews of November 1985. The article was entitled "Can Selenium Modify Cancer Risk?" That article postulated that selenium usage might be helpful against cancer and included 97 scholarly references.

Yet the article on the 1996 study noted that this Larry Clark was surprised at the positive results of the current university selenium study.

Were these two different men or were each of these the very same Larry Clark?

If these two men were in fact the very same man then why was he "surprised" the postulate that selenium usage might be helpful against cancer was confirmed more than a decade later?

Checking through my sources another scientist turned up who is a pioneer in selenium supplementation. It had been many years since last I had spoken with him.

When asked if he knew this Larry Clark of the current study he responded, "Yes, he’s my best friend."

I hit paydirt.

He then affirmed my suspicion that this Larry Clark was also the same scientist as the Cornell co-author of the previous decade.

So why would he express "surprise" at the results of this then just released study on selenium and cancer?

My source told me that when the news media began to bombard the ASU administration with requests to speak with Dr. Larry Clark, the administrators called Dr. Clark in for a meeting. They told him that if any type of endorsement to selenium supplementation was given he would be fired.

At this time I worked for one of the largest newspapers in the world. It was a multiple winner of the prestigious Pulitzer Prize.

Excitedly, I brought this scandalous story to a senior news editor with more than 25 years experience at the newspaper. He asked only one question.

"What’s the local angle?"

I told him that cancer was the #2 killer and #1 feared disease of local readers. He shrugged his shoulders and walked away.

Now here we are five years later with the announcement of this new and redundant selenium study on prostate cancer. It is not due to be completed before 2013. That is more than 100 years after selenium was first put forth as a preventative against cancer.

Am I blue?

I sure am blue!

I am blue that so much suffering has gone on needlessly and will continue to go on needlessly while selenium is kept in the closet.

I am blue in the face that the story of selenium and cancer is still only the smallest of blips on the radar screen of cancer research. This is in spite of the wealth of positive findings that have been unearthed on the subject over many decades.

Epitaph

Dr. Larry Clark died last year. He died from prostate cancer. Is it ironic that he should die from the condition for which his research had shown such promise? Or is it rather ominous that he should die like this after he downplayed the promise of selenium for prostate cancer in spite of his research and personal belief?
