Toxic waste (of money): detoxes and cleanses

Cross-posted from Dietitian at Home.


Apparently we are all chock-full of toxins that need to be flushed out of our bodies; who knew? If we are to judge this claim based on the number of detox kits and programs available, I’d say this problem has hit epidemic proportions. Removing bad stuff from our bodies to feel better and prevent disease, and lose some weight to boot, what’s not to love with this diet trend.

Before we move on, we will need to get these horses to catch up with the cart. Our zealous, hyper health-conscious society simultaneously encourages fear over threats to our well being and aggressive, excessive measures to purge the ills and return to purity. The idea of a detox in the sense intended above is full of assumptions that are often glossed over by the marketers and not actively sought by the consumers. This fantastic article outlines the common myths around detox claims, I highly suggest you read it. To summarize briefly, despite the many claims promoted by these regimens, all fail to explicitly show key evidence for the need for the product. It is not demonstrated that our bodies are truly under attack and unable to cope with environmental exposures. There is no evidence or consensus of which, if any toxins are causing disease. There is no good or compelling evidence to show that these programs are effective in removing any toxins or treating any other illnesses we may have.

As is often said, the dose makes the poison. We encounter thousands of highly toxic substances every day, some naturally occurring, some a product of the human-made environment. Given this hellscape, we still manage to survive to see another day because most of these toxins are in such minute quantities that they pose no health risk, and our bodies are able to effectively eliminate them. The human body has excellent, built-in detoxification systems in the form of the liver and kidneys. These organs are not merely fleshy filters; they are able to convert toxins and waste products into safer forms and safely eliminate them from the body. The best part is that they are self-cleaning, no vitamin-and-cayenne-pepper-laced organ drain-o needed.

Similarly, the intestines (often claimed to harbor toxin-laden sludge) are, by their very nature, self-cleaning. Specific foods/herb mixes/protein shakes/etc. will not make these organs work better or clear more wastes from your system. As for the weight loss accompanied by, or at least touted by these cleanses, this is usually a result of:

  • a) following a very low-calorie diet for a week. Some provide as little as 500-600 calories a day, while 1200 kcal is often considered a bare minimum intake for adults.
  • b) water and muscle loss, particularly with programs involving laxative use.
  • c) removing most processed and restaurant foods from the diet.

When finishing the detox and returning to normal dietary patterns, the weight lost will more than likely return. No, this is not toxins reaccumulating, it is simply the body responding to weight loss and a return to higher calorie intake.

So how to respond to those who report feeling so much better after a cleanse. This is likely the placebo effect at play, often in combination with a more healthful diet. A person wanted to feel differently, so they made a change they believed would be beneficial, they expect positive results, and they are then more likely to report positive results regardless of the clinical outcome of the intervention.

The only times that person will truly experience a toxic overload of a particularly substance is a short period of high exposure, chemical dependency (as with opiates or alcohol), or if the liver or kidneys are failing. If this is the case, these detox kits remain useless and one should seek science-based medical advice immediately. This, though, is a rare occurrence and not one most healthy people should worry about.

Detoxes often make extraordinary and numerous claims, for which they provide little to no evidence. A cleanse product that may plausibly work would need to identify which toxins it removes (preferably explaining the process in a physiologically sound way) and provide good quality evidence to back up the claims. Seeing the dearth of such products at present, best to save your money and spend it on fruits, vegetables, and some stress relief strategies. Your liver and kidneys have got you covered.

Episode 101: “Trace Amounts”

In this episode of Life, the Universe & Everything Else, Ashlyn subjects Gem, Laura, Ian, and Dave to a viewing of “Trace Amounts”, a prominent anti-vaccine “documentary”. It is… not good.

Life, the Universe & Everything Else is a program promoting secular humanism and scientific skepticism that is produced by the Winnipeg Skeptics.

Note: After we recorded this episode, news broke that prominent anti-vaccine group “SafeMinds” funded a $250,000 study in an attempt to demonstrate that thimerosal causes autism. The study was published at the end of September, and actually found no evidence that the thimerosal in vaccines has any link to autism or autism-like changes in the brain. And they killed 79 macaques to do it. Links discussing the study are provided below.

Bad Science Watch Criticises Patient Safety Act for Neglecting Natural Health Product Users

Bad Science Watch Criticizes Patient Safety Act for Neglecting Natural Health Product Users

Bowing to lobbyists the Harper Government has excluded Natural Health Products from newly tabled “Vanessa’s Law”, sacrificing consumer safety for political expediency

Toronto, ON – December 6, 2013 – Bad Science Watch has criticized the newly tabled Patient Safety Act, known as “Vanessa’s Law”, for explicitly excluding Natural Health Products from the regulations to appease lobbyists.

The consumer protection organization claims that the already insufficient regulation of NHPs will be weakened as a result, neglecting the safety of NHP users and practitioners and compromising informed healthcare choice.

“What is otherwise an excellent proposal is horribly undermined by this glaring omission,” said Jamie Williams, Executive Director of Bad Science Watch. “The exclusion of Natural Health Products from the definition of ‘therapeutic products’ means the government would be able to issue a recall for a bad batch of lip balm, but not for herbal remedies adulterated with pseudoephedrine or tainted with toxic heavy metals.”

Bad Science Watch believes Canadians deserve robust safety and enforcement regulations for all health care products, and will be fighting to have the Act’s definition of “therapeutic products” amended to include NHPs.

Bad Science Watch is an independent consumer protection organization dedicated to improving the lives of Canadians by advocating for good science in public policy. More information can be found at www.badsciencewatch.ca.

Natural Remedies Never Kill?

Hey, look! Another completely absurd and almost fact-free article from syndicated columnist Dr. Ken Walker (who writes under the name W. Gifford-Jones):

“Health Canada has been raiding health-food stores, terrorizing proprietors and confiscating natural food supplements,” Dr. Zoltan Rona, an expert on natural remedies, recently told me.

Walker’s article is alt-med propaganda at its most pedestrian. He presents those who peddle “natural remedies” as embattled heroes who are being bullied by Health Canada, which is in the pocket of corporate interests. I find this especially amusing, given that Health Canada has recently been censured for its decision to loosen the licensing requirements for natural health products while bypassing important safety and efficacy checks. (A decision that heavily favours corporate interests, yes: the corporate interests of the multinational corporations who manufacture and distribute natural health products.)

It’s been a while since I’ve played Name That Logical Fallacy, but let’s see… The reader is presented with a false dichotomy in the form of a choice between corporate-controlled pharmaceutical medicine and feel-good “natural” remedies; the deaths resulting from the use of pharmaceutical interventions hint at the fallacy of the perfect solution (the government shouldn’t approve drugs that aren’t perfectly safe and perfectly effective); there’s at least one appeal to antiquity (Nattokinase “has been used for centuries” in Japan); and finally there’s Walker’s completely dishonest (or unforgivably ignorant) claim that “prescription drugs can kill, natural remedies never”: while this isn’t a fallacy, it is the false premise that lies at the very heart of the article.

Walker’s point seems to be that Health Canada should just get out of the way: if the remedy is “natural” (whatever that means) and/or has been used for a long time, its safety and efficacy are unimpeachable. Walker seems to be advocating for some sort of medical free market paradise, a deregulated Wild West of frontier medicine in which the government gives any old snake oil a free pass—snake oil, of course, being completely natural.

“Alternative” medicines can and do kill, directly and indirectly. Natural remedies often lack proper controls to prevent contamination or adulteration; herbal remedies are drugs, and their use in concert with pharmaceuticals can result in unexpected drug interactions; the dose of the active ingredient in herbal remedies is often inconsistent or highly variable (while it is precisely controlled in pharmaceuticals; that’s sort of the point); and when presented with a “natural alternative”, some patients may eschew science-based interventions (that are actually effective). If you’re looking for heart-wrenching stories of people killed as a result of so-called “natural” medicine, here are a couple hundred of them. “Alternative medicine” is most often simply an alternative to medicine.

Walker should be ashamed of himself for promoting such absurdities. But that’s nothing new.
