It’s a part of my paleo fantasy, it’s a part of my paleo dream

There are many fallacies that undergird alternative medicine, which evolved into “complementary and alternative medicine” (CAM), and for which the preferred term among its advocates is now “integrative medicine,” meant to imply the “best of both worlds.” If I had to pick one fallacy that rules above all among proponents of CAM/IM, it would have to be either the naturalistic fallacy (i.e.,...

Gender Differences and Why They Don’t Matter So Much

Several incidents have recently created divisions within the skeptical community.  The latest one was over a casual comment Michael Shermer made in an online talk show. He was asked why the gender split in atheism was not 50/50, “as it should be.” He said he thought it probably was 50/50, and suggested that the perception of unequal numbers might be because attending...

Epigenetics: It doesn’t mean what quacks think it means

Epigenetics. You keep using that word. I do not think it means what you think it means. I realize I overuse that little joke, but I can’t help but think that virtually every time I see advocates of so-called “complementary and alternative medicine” (CAM) or, as it’s known more commonly now, “integrative medicine” discussing epigenetics. All you have to do to view...

Worms, Germs, and Dirt: What Can They Teach Us About Allergies and Autoimmune Diseases?

Humans evolved in an environment where they were exposed to animals, dirt, and a variety of pathogens and parasites. Our immune systems evolved to cope with that environment. Now most of us live in a different environment, with safe drinking water, flush toilets, food inspection, immunizations, and public sanitation. This means that we are far less likely than our ancestors to die...

780.6. What is a fever?

You can tell what a doctor does for a living by the ICD-9 codes they have memorized. There is an ICD-9 code for nearly every medical condition. Weightlessness is 994.9. Must be there for NASA, I have yet to see a weightless patient. Decapitation by guillotine is E978. There, I suppose, in case Marat returns from the dead. There is an ICD-9...

CAM and Creationism: Separated at Birth?

Over the past weekend, I had the opportunity to attend CSICon in Nashville, Tennessee. The Committee for Skeptical Inquiry (“CSI”) combats all sorts of pseudoscience, including creationism/creation science/intelligent design and alternative/complementary/integrative medicine. Our own Team SBM was ably represented by Harriet Hall, David Gorski and Kimball Atwood, whose presentation highlighted the credulous acceptance of CAM in some medical schools, and by Steve...

Thumbthing Worth Reading

I intended to read Sam Kean’s new book The Violinist’s Thumb: And Other Lost Tales of Love, War, and Genius as Written by our Genetic Code  just for fun. I was expecting a miscellany of trivia loosely gathered around the theme of DNA. But I found something much more worthwhile that I thought merited a book review to bring it to the attention...

Learning from Animals: Evolutionary Medicine with a Twist

In 2005, cardiologist Barbara Natterson-Horowitz was called to the zoo to examine a non-human patient, an emperor tamarin with heart failure.  She was surprised when the veterinarian told her not to look her patient in the eyes because eye contact could cause capture myopathy. In this condition, when an animal is captured, restrained, and feels threatened, there is a catastrophic surge of...

Do We Need “Evolutionary Medicine”?

3 years ago I wrote an article critical of “evolutionary medicine” as it was presented in a new book.   Recently a correspondent asked me if I thought another book, Why We Get Sick: The New Science of Darwinian Medicine, by Randolph M. Nesse, MD and George C. Williams, PhD, was a more reasonable approach to the subject. It was published in 1994...

Why haven’t we cured cancer yet? (Revisited): Personalized medicine versus evolution

About a year ago, I addressed what might seem to the average reader to be a very simple question: Why haven’t we cured cancer yet? As I pointed out at the time, it’s a question that I sometimes even ask myself, particularly given that cancer has touched my life. Three years ago, my mother-in-law died of a particularly nasty form of breast...
