The Rosedale Diet: Here We Go Again

The Rosedale Diet

Ron Rosedale, MD has devised a “powerful program based on the new science of leptin.” “Finally — the ultimate diet for fast, safe weight loss, lifelong health, and longer life…” He suggests it will prevent or improve high blood pressure, diabetes, heart disease, osteoporosis, arthritis, and a host of other ills. He repeats the CAM canard that “doctors only treat symptoms” and claims that his diet corrects the underlying cause of obesity, premature aging, and many diseases. That underlying cause is hormone (leptin) dysfunction. His is essentially just another low carb diet, only with more fat and less protein than other versions. His recommendations are ridiculously elaborate and are not supported by good evidence. His diet extrapolates from basic science, is based on speculative hypotheses, and has never been tested to see whether it works and is safe, much less whether it is superior to other diets.

If this sounds vaguely familiar, it should. He is doing what so many proponents of fad diets have done in the past, and he does it poorly. His book is a puerile effort compared to Gary TaubesGood Calories, Bad Calories; Taubes at least marshaled an impressive mass of scientific data, presented a cogent argument, and ultimately acknowledged that more studies would be needed to test his recommendations.

Escharotic Treatment for Cervical Dysplasia: A New Incarnation of Black Salve?

Cervical dysplasia is a precancerous condition picked up by Pap smears. It is most often caused by human papillomavirus (HPV) infection. Mild cases may resolve spontaneously and can be followed by observation with frequent Pap smears, but cervical dysplasia can progress to cancer. The standard treatment is to remove the abnormal cells with a cone biopsy (using a knife) or a Loop Electrosurgical Excision Procedure (LEEP) using a wire loop heated by electricity. Those procedures not only treat the disease, but they provide a pathology specimen that can be examined to rule out more serious or invasive disease. Both LEEP and cone biopsy are 85-90% effective in removing all the abnormal cells. If cancer is suspected, a cone biopsy is preferable because LEEP may damage the edges of the specimen and make it more difficult to interpret. Otherwise, LEEP is often preferred because it is less expensive and doesn’t require anesthesia or an operating room. I have discussed misguided attempts by alternative medicine practitioners to treat cervical dysplasia before.

Surgery is often perceived as scary and not “natural,” so it’s not surprising that a “natural” treatment has been devised to replace surgery. Escharotics are corrosive salves that get their name from the thick dry scab that they can produce called an eschar. The “natural” escharotic treatment alternative for cervical dysplasia involves applying a solution of bloodroot (Sanguinaria canadensis) and zinc chloride. They claim that the solution selectively kills abnormal cells of the cervix while leaving healthy cells unaffected. That claim is almost certainly false, and the efficacy and safety of escharotic treatment has not been properly tested or compared to conventional treatment. (more…)

Vitamins and Cancer Risk

One of the greatest triumphs of marketing over evidence was the incredible rise of vitamin supplement use in the 20th century. Supplement makers successfully created a “health halo” around vitamins, and taking your vitamins became a virtue, something mothers told their children to do. The evidence, however, does not tell such a simple story.

In recent years it has become increasingly apparent that there are unintended consequences to taking vitamin supplements, and in fact there may be a net negative health effect. This is especially true for those who are healthy and don’t need vitamins, and for those who exceed the recommend dosages.

A recent review of the last 20 years of literature on the subject, presented at the American Association for Cancer Research 2015 meeting, found an overall increased risk of cancer among vitamin users. Dr. Tim Byers presented the study, which echoes the result of a 2012 review that he and others published. He specifically refers to two famous studies showing an increased risk of cancer from vitamins.

The 2011 SELECT trial found an overall increased risk of prostate cancer among men taking vitamin E. (more…)

Legislative Alchemy: Naturopathic licensing and practice expansion 2015

Naturopathic genetics: a new specialty?

Naturopathic genetics: a new specialty?

Naturopathy is chock-full of quackery. No doubt about it. Here at SBM and elsewhere, the seemingly limitless nonsense that can be incorporated into naturopathic practice has been documented time and again: detoxification, food “sensitivities,” anti-vaccination ideology, fake diseases (chronic yeast overgrowth, adrenal fatigue, chronic Lyme disease), bogus tests (also here), homeopathy, chelation therapy, assorted other odd-ball treatments, lack of ethical standards, and just general wackiness.

So, let’s give naturopaths licenses to practice primary care! What a good idea.

This affinity for nonsense is perfectly understandable, given their pseudoscience-filled education and foundation in vitalism. Once the scientific method is chucked in favor of “philosophy,” what’s to stop them from simply making things up? As far as I can tell, nothing. But why inflict this on the public under the guise of promoting health, safety and welfare?

To be fair, naturopaths aren’t the only ones who incorporate quackery into their practices. There are chiropractors, acupuncturists, reiki masters, doctors of Oriental Medicine, and “integrative medicine” practitioners. But what sets naturopaths apart, in my mind, is the sheer range of pseudoscience they will accommodate without the slightest hint of doubt in its efficacy or safety and their unwavering belief in their ability to diagnose and treat patients with the expertise and skill of medical doctors. “Delusional” is not too strong a word to describe their utter lack of awareness of their ignorance or the danger to patients they may pose.

“America’s Quack” strikes back

Wile E. Coyote or Dr. Henry Miller? You be the judge!

Wile E. Coyote or Dr. Henry Miller? You be the judge!

Those of you who read my not-so-super-secret other blog (or who follow the news) familiar with this, but I feel that what happened over the last couple of weeks with respect to a man to whom I like to refer as “America’s Quack” is worth posting right here, in modified form.

Last week, a group of ten doctors led by Dr. Henry Miller, most of whom were affiliated either with the Hoover Institution or the American Council on Science and Health (ACSH)—or both—wrote a letter to Lee Goldman, MD, the Dean of the Faculties of Health Sciences and Medicine at Columbia University complaining that Dr. Mehmet Oz shouldn’t be faculty at Columbia University because of his “disdain for science and for evidence-based medicine, as well as baseless and relentless opposition to the genetic engineering of food crops” and “an egregious lack of integrity by promoting quack treatments and cures in the interest of personal financial gain.” The letter produced a fair amount of media attention a week ago. I originally mildly approved of it, but over the course of a few days after the letter was released, my opinion on it soured. The reasons were several and included a profound distaste for threatening letters sent to a person’s employers, admittedly based in part on my own experiences having been at the receiving end of such intimidation tactics, as well as a concern that the letter had been written with no clear purpose behind it other than as a publicity stunt to embarrass Dr. Oz and Columbia. When I learned that Dr. Oz was planning to answer the letter on his show this week, there were predictions that this particularly bone-headed publicity stunt would backfire spectacularly. And it did.

Supplements are the Wild West of health. One Attorney General is out to change that.

4405060141_02f057cbaa_z

Bold moves from the New York State attorney general’s (AG) office are shaking up the supplement industry. In February, the AG accused four retailers (GNC, Target, Walmart, and Walgreens) of selling supplements that failed to contain their labelled ingredients. Using a testing method called “DNA barcoding“, the AG’s office concluded that few of the products it tested actually contained the labelled ingredient, and some contained undisclosed ingredients. It demanded that they stop the sale of those products. All four retailers complied.

When the recall occurred, I noted that the AG may not have had an airtight case: manufacturers and other critics challenged the AG’s methodology, claiming that DNA barcoding was unvalidated, inappropriate, and insufficient. They also stated that the DNA may not survive processing, so the absence of DNA didn’t imply a lack of the original product. Some claimed that the “contaminants” that AG found could have been acceptable fillers. The Attorney General refused to release further information about the testing methods it used, raising further questions about its validity. (more…)

Healthy Habits Global: Spreading False Information about an MLM Coffee with Herbal Additives

Another kind of coffee pyramid scheme. Largest pyramid of coffee cups from the India Book of Records.

Another kind of coffee pyramid scheme. Largest pyramid of coffee cups from the India Book of Records.

When my husband was helping a friend with a project at the house of someone he didn’t know, the lady of the house gave him an earful about the health benefits of the coffee sold by Healthy Habits Global (HHG), a multilevel marketing (MLM) enterprise for which she is a distributor. She sent him home with samples and a brochure with a long list of health claims. She told him she could provide lots of testimonials, and there was a wealth of evidence for her products on PubMed.

Before believing any health claims, especially from an unknown source, it is only prudent to examine the evidence. I consulted the company website, PubMed, and other sources; and I learned that the company’s advertising was full of false information and the whole rationale of the products was questionable. I am not persuaded that HHG coffee has any health benefits. It appears to be just another in a long line of gimmicks used by MLM businesses to sell untested, usually ineffective “health” products to gullible consumers who have little knowledge of science.

The DC as PCP? Drug Wars Resume

Coming soon, to a chiropractor's office near you?

Coming soon, to a chiropractor’s office near you?

Chiropractors are once again engaged in intra-fraternal warfare over the chiropractic scope of practice, a saga we’ve chronicled before on SBM. (See the references at end of this post.) Every time it looks like the warring factions have buried their differences, they come rising to the surface like zombies.

The International Chiropractors Association (ICA), representing the “straight” faction, wants chiropractic to continue as a drugless profession. They are happy to detect and correct subluxations, thereby removing “nerve interference” and “allowing the body to heal itself” in the tradition of Daniel David Palmer. But the American Chiropractic Association (ACA) has bigger fish to fry.

This time, the ICA is upset that the ACA House of Delegates up and decided to establish a “College of Pharmacology and Toxicology,” which would operate under the auspices of the ACA Council on Diagnosis and Internal Disorders. The ACA’s announcement of the “College” is rather vague on details:

The purpose of the College is to further educate the chiropractic profession on clinical matters related to the widespread use of both prescription and over-the-counter medications and nutritional supplements.

I e-mailed the ACA several days ago asking for more information but have yet to receive a reply.

The ICA sees this move as yet another attempt by:

forces at work within some organizations actively promoting incorporating drugs into the chiropractic scope of practice.

Shred360: The Weight Loss Product with the Stupidest Hype Ever

There was a half-page ad in my local paper, thinly disguised as a “Special Report” by a Health and Fitness Editor, for a new fat-melting pill that “could put diet industry out of business by 2016.” I have seen a lot of ridiculous ads for weight loss products, but this one takes the cake. It’s arguably even worse than the one that proclaimed “we couldn’t say it in print if it wasn’t true” and then proceeded to say things in print that weren’t true.

It’s called Shred360. Here are some of the claims:

  • It shook up the fitness industry because it DOUBLES your fat-burning potential.
  • It allows anyone to LOSE INTENSE AMOUNTS OF FAT without grueling workouts or tasteless diet foods.
  • It breaks your fat cells apart and disintegrates them, even while you sleep.
  • Speeds your metabolism by 43%.
  • It vaporizes fat without effort.
  • Its proprietary blend of 16 potent ingredients is scientifically proven.
  • Burns stored fat through thermogenesis and lipolysis.
  • Increases energy and mental clarity almost immediately – guaranteed.
  • Fools your body into feeling full: the ultimate appetite suppressant.
  • Unconditionally guaranteed to make every surplus bit of your unwanted fat disappear effortlessly.
  • Analysts think it will put Jenny Craig and Weight Watchers out of business by 2018 (which doesn’t even make sense if it has already put the entire diet industry out of business by 2016).
  • You can eat like a normal person, skip the gym, and lose the fat you want while you sleep.
  • Produced under highly controlled environmental conditions in small batches, so supplies are very limited.
  • Free samples available for 100 customers – don’t wait to call.

Medical marijuana as the new herbalism, part 3: A “cannabis cures cancer” testimonial

Medical marijuana as the new herbalism, part 3: A “cannabis cures cancer” testimonial

It’s been a while since I discussed medical marijuana, even though it’s a topic I’ve been meaning to come back to since I first dubbed medical marijuana to be the equivalent of herbalism and discussed how the potential of cannabinoids to treat cancer has been, thus far, unimpressive, with relatively modest antitumor effects. The reason I refer to medical marijuana as the “new herbalism” is because the arguments made in favor of medical marijuana are very much like arguments for herbalism, including arguments that using the natural plant is superior to using specific purified cannabinoids, appeals to how “natural” marijuana is, and claims of incredible effectiveness against all manner of diseases, including deadly diseases like cancer, based on anecdotes and testimonials. Now, as I pointed out before, not only am I not opposed to the legalization and regulation of marijuana for recreational use, even though I’ve never tried it myself, but I support it. What I do not support are claims for medical effects that are not backed up with good scientific evidence, and for medical marijuana most claims fall into that category. That’s why I tend to view medical marijuana as a backdoor way to get marijuana legalized. Personally I’d rather advocates of marijuana legalization drop the charade, argue for legalization, and stop with the medical nonsense.

The last time around, I discussed the evidence supporting claims that “cannabis cures cancer” and found them to be wanting based on science. I didn’t however, discuss the “cannabis cures cancer” testimonial machine that drives the claim that marijuana is useful for treating cancer; at least, I only touched on it by discussing briefly Rick Simpson, who claims that his hash oil cures approximately 70% of patients with terminal cancer and a published anecdote in which it was claimed that hemp oil was effective in treating acute lymphoblastic leukemia. (It wasn’t. At least, the evidence presented was not convincing.) Since then, I’ve wanted to revisit the topic of “cannabis cures cancer” testimonials, and, for whatever reason, now seems like a good time to do it.
