To everyone’s disbelief, the National Geographic Society has knowingly and intentionally dived into the cesspool of snake-oil and quack medicine. They are now wading and wallowing waist deep in the putrid smell of a moral cesspool. The link to Part 1 is below the Related Posts.
Harriet
Hall, MD, is a retired Air Force physician, contributor to the blog
Science-Based Medicine and coauthor of the textbook Consumer Health: A Guide to Intelligent Decisions. She pulls no punches in evaluating one of
the Society’s six recent publications, Nature’s
Best Remedies: Top Medicinal Herbs, Spices, and Foods for Health and Well Being:
“The National Geographic store
proclaims, ‘This authoritative guide to the foods, herbs, spices, essential
oils, and other natural substances that alleviate common ailments will enhance
your life—from treating illness to sharpening the mind, losing weight, cleaning
the home, enhancing pregnancy, and reducing the effects of aging.’ No,
it won’t. Its information is biased, incomplete, unscientific, and
sometimes even dangerous. I am a longtime subscriber to National Geographic magazine; I enjoy the great photography and
always assumed the articles provided reliable information. I can no longer
trust it; this book was a bitter disappointment.”
As in all snake-oil claims, the peddlers mix sound
science with nonsense, duping people into thinking the claims are
evidence-based:
“The author, Nancy J. Hajeski, is a
fiction and nonfiction writer with no medical or scientific credentials. The
foreword is by Tieraona Low Dog, MD, an integrative medicine specialist. As
Mark Crislip famously said, ‘If you integrate fantasy with reality, you do
not instantiate reality. If you mix cow pie with apple pie, it does not
make the cow pie taste better; it makes the apple pie worse.’ Integrative
medicine is a marketing term designed to infiltrate quackery into
science-based medicine. It accepts poor-quality evidence and tries to co-opt
some of the standard recommendations of mainstream medicine such as diet,
exercise, and lifestyle changes, giving the impression that only integrative
medicine appreciates their value!”
You know it’s snake-oil when the word “natural” is so
revered it must have descended from the heavens:
“The book subscribes to a logical
fallacy, the naturalistic fallacy: the idea that a natural remedy is inherently
better than a pharmaceutical remedy. That concept is demonstrably false. It
doesn’t matter whether a remedy comes from a plant or a laboratory; what
matters is whether it is effective and safe. Around half of pharmaceuticals
were derived from plants. Drug companies improved the natural remedy using
science. They identified and isolated the active ingredient, developed a pure
version with a controlled dosage, and often synthesized the active compound and
altered it to improve its efficacy and safety.”
There is a dramatic contrast between the information
in the Society’s books and reliable, scientific publications:
“I have long relied on another
resource that is much more trustworthy and complete, the Natural
Medicines Comprehensive Database. It covers all the published research
(with citations) on vitamins, minerals, and dietary supplements. It lists
adverse reactions, safety concerns, drug interactions, warnings, and more. It
rates each natural medicine for effectiveness and safety. Only 5 percent are
rated as ‘effective,’ and almost all of those are vitamins, minerals, and
medicines that are also available as prescription or over-the-counter products
approved by the FDA. Others are rated likely or possibly effective, likely or
possibly ineffective, or ineffective. Safety ratings are likely or possibly
safe, likely or possibly unsafe, or unsafe. For a great many entries, they say
there is insufficient reliable evidence for them to provide a rating.”
Just one specific example is the list of possible
remedies for urinary tract infections:
----Drink a minimum of
eight glasses of water a day
----Eat cucumbers
because they are full of water and can supply extra fluid to your system
----Drink ginger tea
----Avoid chocolate,
citrus fruit, carbonated beverages, and caffeine
----Apply a heat
source over the bladder
----Drink cranberry
juice, three glasses a day
----A half cup of
blueberries
----Baking soda
----Parsley water
“There is little or no scientific
evidence for any of these. They have not been evaluated in controlled clinical
studies; they are mainly old wives’ tales. In an article on the Science-Based
Medicine blog, pharmacist Scott Gavura reviewed the research on
cranberry juice and concluded: ‘There is no persuasive evidence that
cranberries can prevent urinary tract infections.’ He called it ‘an alternative
medicine zombie that’s impervious to evidence.’”
National Geographic and sound science have become as
opposite as oil and water:
“It’s easy enough to cherry-pick the literature
and find a study or two that supports any given natural remedy, and that is
what the author of this book has done. The scientific approach is to look
at all the published evidence, pro and con, evaluate the quality of the
studies, and put all the evidence into perspective before assuming that the
remedy is effective. A scientist would not be satisfied with a list of ‘health
benefits’ but would insist on knowing about negative studies, adverse
reactions, interactions with other treatments, safety, and much more. And if it
appears that a natural remedy is effective, the next question is whether it is
the best choice. How does it compare to other treatment options that might be
more effective and/or safer? The book provides no comparisons.”
Over
and over and over again, snake-oil peddlers rely exclusively on the placebo
effect for any so-called cures:
“The description of the book on the
Amazon website calls it ‘a guide to the world’s most therapeutic foods, herbs,
spices, and essential oils’ that will ‘allow the healing power of nature to
energize your body and enrich your life, providing a surefire path to good
health and well-being.’ It calls the book ‘an authoritative guide.’ I have
shown that it is clearly not authoritative, and Amazon’s
description is highly misleading. There isn’t a shred of evidence that any of
these remedies will ‘energize’ your body, whatever that means. The remedies
will please those who believe the naturalistic fallacy; suggestion will lead to
a placebo response and will make the user feel virtuous in the belief that they
have taken action to improve his or her health. There are plenty of subjective
results, but not much in the way of objective effects.”
Hall’s conclusion:
“If National Geographic had
presented this as a coffee table book describing folklore and belief systems,
illustrated by lots of pretty pictures, I wouldn’t have objected. But they
presented it as an evidence-based review of the top natural medicinal remedies,
and they presented the natural medicines as effective, without mentioning what
Paul Harvey would have called ‘the rest of the story.’ This is superstition,
not science. It is misleading, incomplete, and potentially dangerous. Nothing
in this book can be trusted without confirmation from other, more reliable
sources. National Geographic let us down. They should be ashamed.”
