I’m fed up! In August 2009 I wrote about Protandim, pointing out that it’s not supported by good evidence. I thought I had made myself clear; but apparently I had only made myself a target. True believers have deluged the Internet with attacks on my article, calling it mere “opinion,” ignoring… read more "Pursued by Protandim Proselytizers"
Artificial Sweeteners: Is Aspartame Safe?
Note: This was originally published as a “SkepDoc” column in Skeptic magazine under the title “Aspartame: Safe Sweetener or Perilous Poison?” and is reprinted here with the kind permission of Michael Shermer. There are other artificial sweeteners not specifically addressed here, but as far as I know there are no… read more "Artificial Sweeteners: Is Aspartame Safe?"
Benedetti on Placebos
There has been an ongoing debate about placebos on SBM, both in the articles and in the comments. What does it mean that a treatment has been shown to be “no better than placebo?” If our goal is for patients to feel better and they feel better with placebos, why… read more "Benedetti on Placebos"
Scientific American Mind Is Not So Scientific
When Scientific American first announced that they would publish Scientific American Mind, I hurried to subscribe, thinking it would keep me informed about new developments in a field I am passionately interested in. I have enjoyed the magazine, particularly the regular columns, the news items about research findings, the reviews… read more "Scientific American Mind Is Not So Scientific"
TIME Magazine, Dr. Oz, What to Eat, and Supplements
Here on SBM we have frequently had cause to criticize the media for poor science reporting and for spreading misinformation. Among many other individual offenders, we have criticized Dr. Oz for promoting alternative medicine on his TV show and gullibly promoting guests who pretend to talk to the dead… read more "TIME Magazine, Dr. Oz, What to Eat, and Supplements"
Are Prenatal Ultrasounds Dangerous?
Several questionable sources are spreading alarms about the possible dangers of prenatal ultrasound exams (sonograms). An example is Christine Anderson’s article on the ExpertClick website. In the heading, it says she “Never Liked Ultrasound Technology.” [She] has never been sold on the safety using Ultrasounds for checking on the fetuses of… read more "Are Prenatal Ultrasounds Dangerous?"
Testing a Chinese Herbal Flu Remedy
During the early days of the 2009 H1N1 influenza A pandemic, the popular herbal formula maxingshigan–yinqiaosan was used widely by TCM practitioners to reduce symptoms. (It’s hard to pronounce and spell, so I’ll refer to it as M-Y.) A new study was done to test whether M-Y worked and to… read more "Testing a Chinese Herbal Flu Remedy"
Wishing Away Warts
Common warts (verruca vulgaris) are more of a nuisance than a serious health problem, but they are interesting. There is a whole mythology surrounding their cause (touching toads?) and treatment (everything from banana peels to vitamin C). Many people believe they can be made to vanish by suggestion or hypnosis.… read more "Wishing Away Warts"
What to Expect When You’re Expecting
A correspondent asked me to review the book What to Expect When You’re Expecting by Heidi Murkoff and Sharon Mazel. She wrote “I’m very worried about this book.” She had just seen an NPR article about the book and was alarmed because it provided an excerpt from the book recommending that… read more "What to Expect When You’re Expecting"
Belief in Echinacea
Note: The study discussed here has also been covered by Mark Crislip. I wrote this before his article was published, so please forgive any repetition. I approached it from a different angle; and anyway, if something is worth saying once it’s probably worth saying twice. Is Echinacea effective for preventing… read more "Belief in Echinacea"
