I don’t tend to worry too much about hydration, except when I exercise. I’ve been running regularly for over 15 years, and since I started I’ve usually carried water, or for longer runs, I drink old-school Gatorade. The formulation is basic: sugar, salt, and potassium. There are hundreds of electrolyte products marketed for athletics, but I’ve been faithful to the original: It’s cheap, I don’t mind the taste (even when it’s warm), you can buy it nearly anywhere, and it’s the usual liquid (besides water) offered at races. After exercise, I rehydrate with plain water, preferring to get my electrolytes and carbohydrates from food, rather than a specialty beverage, some of which are “designed” to support rehydration after exercise. The science of sports and hydration is constantly evolving, and so is the marketing. I’m apparently an outlier by still running with Gatorade. New hydration products criticize Gatorade for being artificial and inferior, arguing that natural sources of hydration are better. There’s been an explosion of rehydration beverages, marketed both for everyday hydration and sport purposes. Coconut water was the first natural product to find fairly wide popularity as a sports-oriented beverage. Now you can find maple water, cactus water, watermelon juice and even artichoke water. Is “natural” hydration better that substitutes, including plain old water? (more…)

The FDA recently announced it would send field staff out to collect samples of commercially-manufactured raw dog and cat food. The samples will be analyzed for Salmonella, Listeria monocytogenes and E. coli, all of which have been found in raw pet food, in the animals who eat it, in their feces, on their bodies after eating it, in the areas they inhabit, and on their owner’s bodies. Not surprisingly, this has led to both pet and human infection and illness. If the FDA finds pathogens, it could result in a recall, a press release and Reportable Food Registry Submission. The next day, the CDC joined the effort to curb illness caused by pathogens in raw pet food by posting information on safe handling.
Because of the risk to public health, and the lack of any proven benefit of raw pet food diets, the FDA does not recommend them.
However, we understand that some people prefer to feed these types of diets to their pets.
And why is that? For some of the same reasons humans follow absurd diet fads: the “lone genius” discovery, it’s “natural,” anecdotal evidence, appeal to antiquity, anti-corporate sentiment, and “holistic” practitioner recommendations.
We are at a disadvantage. We have to rely on reality to validate the practice of medicine. Anatomy, physiology, pharmacology, chemistry, the basic sciences that made up the first two years of medical school education and a huge chunk of pre-med. And we have to rely on the truth, as slippery a concept as that can be. I can’t just make up a disease or a therapy.
It would be so much easier to not have to worry about reality in deciding on a disease and treatment for people with symptoms.
I came across “Healthy Life: Leaky Gut Syndrome” in my feeds. I am always attracted to exclamation marks! They must mean something important! Or surprising to the author!
It’s called “leaky gut syndrome” and patients say it can wreak havoc on everyday life, but some doctors say there’s no such thing!
Naturopaths, along with some chiropractors, acupuncturists and a few “integrative” physicians, are advising patients that they should be tested for MTHFR genetic mutations. Typically, the naturopath will start with the pitch that “conventional” medical doctors are ignoring your genes as a possible source of your health problems. (And it is mostly naturopaths who are doing this – just Google “naturopath MTHFR genetic mutation” and see what comes up.) NDs know better, of course – it could be a MTHFR genetic mutation causing your maladies.
Just what is the MTHFR gene? Allow me to introduce some actual scientific information here. According to Genetics Home Reference, a service of the National Library of Medicine,
the MTHFR gene provides instructions for making an enzyme that plays a role in processing amino acids, the building blocks of proteins. This particular enzyme is important for a chemical reaction involving forms of the vitamin folate (also called vitamin B9), a reaction required for the multistep process that converts the amino acid homocysteine to another amino acid, methionine. The body uses methionine to make proteins and other important compounds.
Back to pseudoscience. Next comes the scare tactic: telling you how a MTHFR mutation might affect your health: anxiousness, adrenal fatigue, brain fog, cervical dysplasia, increased risk of many cancers (including breast and prostate), low thyroid, leaky gut, high blood pressure, heart attacks, stroke, Alzheimer’s disease, diabetes, and miscarriages.

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 Taubes‘ Good 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.

Let food be thy medicine and medicine be thy food.
Who said anything about medicine? Let’s eat!
Who hasn’t seen or heard Hippocrates’ famous quote about letting food be your medicine and your medicine your food? If you have Facebook friends who are the least bit into “natural” medicine or living, you’ve almost certainly come across it in your feed, and if you’re a skeptic who pays the least bit of attention to what’s going on in the quackosphere you will almost certainly have seen it plastered on a picture as a meme, either using a picture of Hippocrates or pictures of plates of green, leafy vegetables, or both. I like to view the fetishization of “food as medicine,” to cite Hippocrates, as one of the best examples out there of the logical fallacy known as the appeal to antiquity; in other words, the claim that if something is ancient and still around it must be correct (or at least there must be something to it worth considering).
Of course, just because an idea is old doesn’t mean it’s good, any more than just because Hippocrates said it means it must be true. Hippocrates was an important figure in the history of medicine because he was among the earliest to assert that diseases were caused by natural processes rather than the gods and because of his emphasis on the careful observation and documentation of patient history and physical findings, which led to the discovery of physical signs associated with diseases of specific organs. However, let’s not also forget that Hippocrates and his followers also believed in humoral theory, the idea that all disease results from an imbalance of the “four humors.” It’s also amusing to note that this quote by Hippocrates is thought to be a misquote, as it is nowhere to be found in the more than 60 texts known as The Hippocratic Corpus (Corpus Hippocraticum).
But Hippocratic doctors clearly saw a difference between food and medicines. In fact, food was considered as a material that could be assimilated after digestion (e.g. the air was also food) and converted into the substance of the body. For example, food was converted into the different parts of the body such as muscles, nerves, etc. By contrast, the concept of medicines at the time was a product which was able to change the body’s own nature (in terms of humor quality or quantity) but not be converted into the body’s own substance. Thus a food wasn’t considered a medicine. A possible root of the food-medicine confusion is the following cryptic phrase found in the work On Aliment: “In food excellent medication, in food bad medication, bad and good relatively”.3 This text is nowadays attributed to the Hellenistic period, but was considered to be Hippocratic in Antiquity by Galenus in particular.
Now, it is certainly true that Hippocrates and his followers used diet to treat many illnesses, it’s not really clear what sort of success they had. However, this ancient idea that virtually all disease could be treated with diet, however much or little it was embraced by Hippocrates, has become an idée fixe in alternative medicine, so much so that it leads its proponents twist new science (like epigenetics) to try to fit it into a framework where diet rules all, often coupled with the idea that doctors don’t understand or care about nutrition and it’s big pharma that’s preventing the acceptance of dietary interventions. That thinking also permeates popular culture, fitting in very nicely with an equally ancient phenomenon, the moralization of food choices (discussed ably by Dr. Jones a month ago).
Brian Clement is a charlatan. Unfortunately, that doesn’t seem to be a problem for the State of Florida. I made two (which turned into three) attempts to get the state to take action against Clement or the Hippocrates Health Institute, where he serves with his wife Anna Maria Gahns-Clement as co-director. All of them failed. Brian Clement slithered through the cracks in Florida law each time.
Before we get into the details of Florida’s failure to act, a bit of history (and there is plenty of it) is in order.
In recent months, Clement’s sordid cancer quackery has been well-documented in the media as well as in the science “blogosphere”. (I’ve listed what I hope is a — but almost certainly isn’t — complete blog archive at the end of this post. Many of the Canadian Broadcasting Corporation [CBC] and other news reports are linked in these posts.) Most of the coverage has centered on two Canadian girls suffering from lymphoblastic leukemia whose parents pulled them from conventional cancer therapies, which gave them an excellent chance of survival, in favor of treatment at the Hippocrates Health Institute (HHI), a sprawling spa in West Palm Beach, Florida, licensed as a massage establishment by the state.
Clement gave a talk in Canada, in 2014, claiming “we’ve had more people reverse cancer than any institute in the history of health care.” (“We” is the operative word here, because it later served as Clement’s ticket to avoid prosecution by the Florida Board of Medicine, as you shall soon find out.) The girls’ families were impressed.
Sadly, one of the girls, Makayla Sault, died earlier this year. The other, identified only as “JJ” in the media because of a publication ban, has returned to conventional treatment. However, her mother apparently remains under the influence of Clement: JJ is restricted to a raw foods diet and is still being followed, if that is the right word, by HHI. (more…)
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.
Pepsi has announced that it will remove aspartame from its formulation of diet Pepsi products in the US this year. Apparently this is a reaction to a 5% drop in the sales of Pepsi. Seth Kaufman, vice-president of Pepsi, said “Aspartame is the number one reason consumers are dropping diet soda.”
This move comes in the same week that Chipotle announced it is removing GMO food from its food chain. Unlike Pepsi, who cited only public opinion, Chipotle went one step further and directly cited pseudoscientific fears of GMOs as their justification. (But that’s another story.)
Like GMOs, aspartame has been widely studied and found to be safe, but remains the target of fear-mongering and conspiracy theories. It is not clear why this one food additive has continued to be the target of a fake controversy, other than that fears and conspiracies can take on a life of their own. The best example of anti-aspartame conspiracy theories comes from Janet Starr Hull, who wrote:
I will never accept the news of aspartame safety. I think it is a “business” decision to discredit/discount the research results that aspartame DOES cause cancer, major nerve disorders, birth defects, and brain imbalances. Think about it – can you imagine the chaos that will occur when the truth of aspartame dangers is accredited. The FDA has known about the dangers, the corporations have known about the dangers, and the medical community (if it is really worth anything) has known about the dangers.
That is a common claim of conspiracy theorists – the truth is being suppressed out of fears that it will bring chaos if revealed. I think our society will survive Pepsi moving over to a different sweetener. (more…)
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.
