I suggested in last week’s column that public health officials be excused for “honest” mistakes inadvertently leading to two postal worker deaths from inhalation anthrax. But their bad advice about the flu shot as an aid to the diagnosis of anthrax is another matter. Continue reading Flu Shot Frenzy Not Anthrax Answer

Alarmists in the federal government and media were wrong about the “potency” of the anthrax found in Sen. Tom Daschle’s office. This error hasn’t dissuaded those who are exploiting the alleged “potency” to blame the recent anthrax letters on state-sponsored terrorism. Continue reading Misinformation Is Real Anthrax Danger

Asbestos fibers in the air and rubble following the collapse of the World Trade Center is adding to fears in the aftermath of Tuesday’s terrorist attack. The true tragedy in the asbestos story, though, is the lives that might have been saved but for 1970s-era hysteria about asbestos. Continue reading Asbestos Could Have Saved WTC Lives

Soft Drinks, Hard Bias

By Steven Milloy
April 20, 2001, FoxNews.com

Sen. Patrick Leahy, D-Vt., just introduced a bill to restrict sales of soft drinks in schools. “The Better Nutrition for School Children Act of 2001” comes on the heels of a series of anti-soft drink articles in The Washington Post.

But Sen. Leahy should know better than to believe everything he reads.

The notion that children who consume soft drinks tend to be obese is intuitively appealing. That is undoubtedly why the Post felt comfortable running three articles on Feb. 27 — “Soft Drinks, Hard Facts,” “Schools Hooked on Junk Food” and “Easy Cash Eroding Their Principles” — alarming readers about kids’ soft drink consumption.

The bias in the Post’s reporting is breathtaking.

“Soft Drinks, Hard Facts” reported: “One very recent, independent, peer-reviewed study demonstrates a strong link between soda consumption and childhood obesity. One previous industry-supported, unpublished study showed no link.”

As opposed to the latter study, the former study apparently was “independent” because it was funded by federal agencies, including the Centers for Disease Control and Prevention, and the National Institute of Diabetes and Digestive and Kidney Diseases.

But both government agencies already urge that children avoid soft drinks despite the scarcity of scientific data, ostensibly only one study, to support such advocacy. The agencies are hardly disinterested in the outcome of the research.

A background check into the authors of the “independent” study reveals the study outcome is not unexpected. The authors have long been in the childhood obesity research business, blaming childhood obesity on diet and television-viewing habits.

It shouldn’t be surprising longtime childhood obesity researchers might be somewhat biased toward producing results that promote their area of research interest.

The Post expanded on the “independent” study, claiming each daily serving of a sugar-sweetened soft drink increased the rate of childhood obesity 1.6 times. This rate was estimated based on a statistical analysis of a small population of children.

It is elementary in such an analysis that reported increases in health effects rates on the order of 2.0 and less are considered weak and unreliable.

More accurately reported, the “independent” study reported no significant increase in obesity for soft-drink consumption among children.

The Post went to great pains to explain this basic rule when similarly weak statistics were used to link abortion with increased risk of breast cancer. With respect to women who had abortions having 1.5 times more breast cancer, the Post reported: “Though this may appear to be a large increase in risk … it falls in the barely detectable range.”

Why the double standard? A cynic might suggest that abortion is more politically correct than soft drinks.

The Post’s conduct gets worse.

Researchers from the Georgetown University-affiliated Georgetown Center for Food and Nutrition Policy presented four new studies at the Experimental Biology 2001 annual meeting on April 3.
The studies were based on analyses of data from two national surveys: The U.S. Department of Health and Human Services’ National Health and Nutrition Examination Survey and the U.S.

Department of Agriculture’s Continuing Survey of Food Intake. The researchers reported:

  • No relationship between consumption of carbonated soft drinks and obesity among 12- to 16-year-olds.
  • Soft drinks did not reduce calcium consumption among 2- to 20-year-olds.
  • Teens who consumed more soft drinks were as physically active as those who consumed fewer soft drinks.
  • Soft drink consumption did not harm diet quality among children and teens as measured by the USDA’s Healthy Eating Index.

The researchers added, “We need to stress the vital role of physical activity for all students, not just the best athletes chosen for varsity sports teams.” Though the media was informed of the Georgetown studies’ release before the meeting, the Post didn’t see fit to report the news.

The omission is no surprise. The Georgetown studies were funded by the National Soft Drink Association. Though the group had no power to influence or alter the research findings, this funding arrangement apparently didn’t meet the Post’s dubious standard for “independence.”

But should the studies’ funding source really make them less newsworthy? Shouldn’t scientific studies be judged on their technical merits, not their financing? On their scientific, not political correctness?

The new studies certainly are not the final word on soft-drink consumption and children’s health, nor should they be. They are simply another analysis that should be considered among the limited database of relevant studies.

The problem, though, is that it seems as if the Post is more interested in frightening parents and children, and senators, rather than informing them.

The tail-end of the fiber myth

By Steve Milloy
February 2, 2001, FoxNews.com

If you’ve been shoveling down high-fiber cereals every morning in hopes of preventing colon cancer, you can stop.

The 30-year-old notion that cereal fiber reduces colon cancer risk is turning out to be yet another government-sanctioned myth. It may be time for the Food and Drug Administration to butt out of our colons.

A study published in this week’s The Lancet reports that a “… high-fiber diet and supplementation with wheat bran fiber may not be effective strategies for the prevention of [colon cancer].”

By itself, the study would not be overly persuasive. But it is the fourth study in a major medical journal in the last two years to reach the same conclusion, including a January 1999 study in the New England Journal of Medicine that followed about 89,000 women over a period of 16 years.

How did the myth get started?

British medical missionary Dr. Denis Burkitt gave birth to the idea that dietary fiber reduced colon cancer risk in 1971. Burkitt observed — almost casually, not in any scientific manner — that poor rural Africans had much less colon cancer than Westerners. He theorized this was due to the Africans’ fiber-rich diet.

The idea was that larger, faster moving stools reduced the colon’s exposure to carcinogenic bile acids. The theory’s intuitive appeal propelled it to become conventional wisdom. But it lacked persuasive scientific support.

Some studies seemed to support the theory; others did not. None of the studies were particularly well-designed — they tended to be retrospective in nature, relying on unverified self-reports of subjects’ dietary and lifestyle habits.

The National Research Council, the research arm of the National Academy of Sciences, thought the theory was so speculative that it declined in 1982 to make a specific recommendation about dietary fiber and colon cancer.

Eventually, though, commercial interests perceived value in the theory and the scientific controversy became a memory.

In 1984, cereal manufacturer Kellogg placed a message on its All Bran cereal claiming scientific evidence linking a high fiber diet with a reduction in colon cancer risk. The FDA took no action against Kellogg, though the claim seemed to defy a longstanding FDA rule prohibiting health-related messages on food products.

The National Research Council reversed itself and came out in favor of a link between dietary fiber and reduced colon cancer risk in 1989 — though the state of the science had not changed.

A 1990 federal law clarified the FDA’s authority over food label content and the agency subsequently issued rules permitting health-claims labeling, provided there was some scientific support.

In a 1997 effort to boost stagnant cereal product sales, Kellogg petitioned the FDA for permission to make the claim that some of its products contain ingredients that may help prevent certain cancers, especially colon cancer.

In July 1999, the FDA permitted whole-grain foods to claim on their labels that “diets rich in whole-grain foods and other plant foods and low in total fat, saturated fat and cholesterol may reduce the risk of heart disease and certain cancers.”

The FDA did not give the scientific research on whole-grain foods the scrutiny that goes into the approval of a new drug. Instead, the agency relied on recommendations made by the NRC 10 years earlier. The FDA ignored the NEJM study that was published six months before the approval of the Kellogg petition — even though it was the largest study ever on dietary fiber and colon cancer.

The result of the FDA’s scientific sloth is that millions of consumers will continue to be misled for the foreseeable future about an important health issue — all the while choking down bran cereals and imagining they’re preventing colon cancer. Certainly whole grains are part of a balanced diet. But by overestimating the benefits, many will have a false sense of security.

And while the FDA is allowing companies to market junk science-fueled myths, the agency uses junk science to remove a product with known benefits. Maybe you’ve noticed that your favorite laxative doesn’t work as well as it used to.

Researchers from the U.S. government’s National Toxicology Program reported to the FDA in April 1997 that mice fed high doses of the compound phenolphthalein had higher rates of cancer. At the time, phenolphthalein was the most effective active ingredient in laxative products.

The FDA bullied laxative manufacturers to reformulate their products without phenolphthalein despite that: (1) the mice were genetically engineered to be more susceptible to cancer — they were, in a sense, “cancer time bombs”; (2) the doses of phenolphthalein were 30 times higher than consumer use; and (3) phenolphthalein was used as a laxative ingredient for more than 100 years with absolutely no indication of increased cancer risk among users.

The several scientific studies published after the FDA decision also failed to link laxative-use with increased cancer risk.

Hey, who needs laxatives when you’ve got bran?

President Clinton this week announced a new effort to fight colon cancer, including, among other recommendations, that adults over the age of 50 have annual colon cancer screenings. Every year, there are an estimated 130,000 new cases of colon cancer and more than 50,000 deaths from the disease.

Colon cancer may be cured if detected early enough. It’s too bad there doesn’t seem to be any cure for junk science at the FDA.
