My stimulant of choice is coffee. I started drinking it in first-year university, and never looked back. A tiny four-cup coffee maker became my reliable companion right through graduate school.
But since I stopped needing to drink a pot at a time, an entirely new category of products has appeared — the energy drink. Targeting students, athletes, and others seeking a mental or physical boost, energy drinks are now an enormous industry: From the first U.S. product sale in 1997, the market size was $4.8 billion by 2008, and continues to grow. (1)
My precious coffee effectively has a single therapeutic ingredient, caffeine. Its pharmacology is well documented, and the physiologic effects are understood. The safety data isn’t too shabby either: it’s probably not harmful and possibly is even beneficial. (I’m talking about oral consumption — no coffee enemas. Please.) In comparison, energy drinks are a bewildering category of products with an array of ingredients including caffeine, amino acids, vitamins, and other “natural” substances and assorted “nutraceuticals,” usually in a sugar-laden vehicle (though sugar-free versions exist). Given many products contain chemicals with pharmacologic effects, understanding the risks, signs of adverse events, and potential implications on drug therapy, are important.
So are energy drinks just candied caffeine delivery systems? Or are these syrupy supplements skirting drug regulations?
The Message
The ads are seductive. Who doesn’t want more energy? Who doesn’t want their mind and body “vitalized?” And don’t we have time-starved lifestyles? Initially envisioned for athletes, energy drinks are now marketed mainly towards teens and young adults, where uptake has been dramatic. Cross-promotion with extreme sporting events, and creating names like “Full Throttle,” “Rockstar,” and even “Cocaine” burnish the “extreme” image. The market is now segmented further with products targeted at women, vegetarians, diabetics, celiacs, and more. However you identify yourself, there’s probably an energy drink developed with you in mind. Read more »

It seems that for every established science there is an ideological group who is motivated to deny it. Denialism is a thriving pseudoscience and affects any issue with the slightest political or social implications. Sometimes, even easily verifiable facts can be denied, as people seem willing to make up their own facts as needed.
Denialists have an easy job — to spread doubt and confusion. It is far easier to muddy the waters with subtle distortions and logical fallacies than it is to set the record straight. Even when every bit of misinformation is countered, the general public is often left with the sense that the topic is controversial or uncertain. If denial is in line with a group’s ideology, then even the suggestion of doubt may be enough to reject solid science.
We see this when it comes to the effectiveness of vaccines, the evolution of life on earth, and anthropogenic global warming. A recent Pew poll shows that the campaign of global warming denial has been fairly successful — while the science becomes more solid around the consensus that the earth is warming and humans are contributing to this, the public is becoming less convinced.
I often encounter denial even when it comes to simple things, like body weight. You would think that the question of how many Americans are overweight or obese would be fairly straightforward, but no data is so straightforward that it cannot be distorted by dedicated ideologues. Read more »

Myths and misconceptions about cancer abound. Oncologists are frequently criticized for torturing patients by burning, cutting and poisoning without making any real progress in the war against cancer. Siddhartha Mukherjee, an oncologist and cancer researcher, tries to set the record straight with his new book The Emperor of All Maladies: A Biography of Cancer.
It is a unique combination of insightful history, cutting edge science reporting, and vivid stories about the individuals involved: The scientists, the activists, the doctors, and the patients. It is also the story of science itself: How the scientific method works and how it developed, how we learned to randomize, do controlled trials, get informed consent, use statistics appropriately, and how science can go wrong. It is so beautifully written and so informative that when I finished it I went back to page one and read the whole thing again to make sure I hadn’t missed anything. I enjoyed it just as much the second time. Read more »

Dr. Kent Bottles is in the midst of a very thoughtful multi-part blog post under the heading, “The Difficult Science Behind Becoming a Savvy Healthcare Consumer.”
Part I examined “the limitations of science in helping us make wise choices and decisions about our health.”
Part II explores “how we all have to change if we are to live wisely in a time of rapid transformation of the American healthcare system that everyone agrees needs to decrease per-capita cost and increase quality.”
Both parts so far have addressed important issues about news media coverage of healthcare. Read more »

In November 2010, the California Department of Consumer Affairs (DCA) finally decided to act responsibly and forbid the prevalent practice of Chinese bloodletting by licensed acupuncturists. The practice became a concern for the DCA when allegations of unsanitary bloodletting at a California (CA) acupuncture school surfaced.
The incident allegedly occurred during a “doctoral” course for licensed practitioners. The instructor was reportedly demonstrating advanced needling and bloodletting techniques. During the process, he took an arrow-like lancing instrument that is called a “three-edged needle” (三棱针), sharpened it with sandpaper, cleaned it with alcohol, and then asked a student-volunteer to roll a towel around his neck. The instructor then cleaned the student’s temporal region with alcohol, and punctured a superficial blood vessel with the arrow-like instrument. The student then held his head over the garbage can, gushing blood for awhile. Read more »
