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 convincing health concerns about any of them, just this same kind of...

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 not prescribe them? Do placebos actually do anything useful? What can science...

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 that alert me to books I will want to read, the “Ask...

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 and pretend to heal people with carnival sideshow tricks. We tend to be...

Menstrual Synchrony: Do Girls Who Go Together Flow Together?

When women live together, do their menstrual cycles tend to synchronize? It’s been a long time since I first heard that claim. I didn’t believe it, for a number of reasons. I had never observed it myself, I saw no plausible mechanism to explain how it could happen, I thought the statistics to prove it would be problematic and complicated, and I...

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 pregnant women, and for the last decade her fears have been confirmed...

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 compare it to the prescription drug oseltamivir. It showed that M-Y did...

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. I used to believe that too. Every doctor has wart stories. Here...

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 patients with morning sickness “Try Sea-Bands” and “Go CAM Crazy.” She knew from...

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 and treating the common cold or is it just a placebo? My...
