Natural versus “natural” in CAMworld
“When I use a word,” Humpty Dumpty said in rather a scornful tone, “it means just what I choose it to mean — neither more nor less.” “The question is,” said Alice, “whether you can make words mean so many different things.” “The question is,” said Humpty Dumpty, “which is to be master— that’s all.” From: Through the Looking Glass, and What...
Vitamin C strikes (out) again
A new research paper on vitamin C and cancer came out recently, but didn't get much attention in the press. Why not? Because this one found vitamin C actually made things worse.
What’s for Dinner?
Diet advice changes so fast it’s almost a full-time job to keep up with it. Avoid cholesterol; no, avoid saturated fats; no, avoid trans-fats. Avocados are bad; no, avocados are good. Wheat germ is passé; now omega 3s are de rigueur. The supermarket overwhelms us with an embarras de richesses, a confusing superabundance of choices from “organic” to low-sodium. How can we...
Misleading Ads in Scientific American
I’m frequently asked, “Is what that ad says really true?” Three recent inquiries have been about products advertised in Scientific American. An ad may acquire a certain cachet by appearing in a prestigious science magazine, but that doesn’t mean much. Scientific American’s editorial standards apparently don’t extend to its advertising department. I remain skeptical about the claims for all three of these:...
High dose vitamin C and cancer: Has Linus Pauling been vindicated?
Treating cancer with high-doses of vitamin C is a zombie idea that began with Linus Pauling, and has failed to die ever since. But has new research vindicated this idea? No. No in any meaningful way. This work is the very definition of a long run for a short slide.
Should I Take a Multivitamin?
I’ll start with a confession. I used to do something irrational. I used to take a daily multivitamin, not because I thought there was good scientific evidence to support the practice, but for psychotherapy. I tried to eat a healthy diet and worried about it. By taking a pill, I could stop worrying. Then I found out that higher intake of vitamin...
Another State Promotes the Pseudoscientific Cult that is “Naturopathic Medicine.” Part 1
Minnesota has recently become the 15th state in the U.S. to formally endorse the claims of a tiny group of naturopaths who portray themselves as physicians.* The bill , like the popular-media “CAM” reports that Steve Novella criticized on Wednesday, merely parrots what these naturopaths claim about themselves. It reveals no attempt to investigate or to judge the tenets of the field. The following excerpts present...
The Real ID
Stein: When we just saw that man, I think it was Mr. [PZ] Myers, talking about how great scientists were, I was thinking to myself the last time any of my relatives saw scientists telling them what to do they were telling them to go to the showers to get gassed.Stein (speaking about the Holocaust): …that was horrifying beyond words, and that’s...
Super Fruit Juices – The New Snake Oil
The core principle of science-based medicine is that health care decisions should be based upon our best current scientific evidence and understanding. When applied to the regulation of health products this means that health claims should first be required to meet some reasonable threshold of scientific evidence before they are allowed. Admittedly this is not a purely scientific question but the application...
