Voodoo Medicine: Time To Stop

by Jeff Schweitzer

Jeff Schweitzer is a scientist and former White House Senior Policy Analyst; Ph.D. in marine biology/neurophysiology

The world’s most celebrated athlete standing on the podium in Rio in honor of receiving yet another gold medal has something important in common with your lazy uncle throwing back a cold one in his Barcalounger. Yes, swimming powerhouse Michael Phelps, purple-spotted from cupping therapy, and your slovenly relative with a beer gut both share a bond — a weakness in succumbing to the allure of voodoo medicine. Modern-day snake oil salesmen hawking quick cures and TV doctors peddling the latest diet miracle with blatantly ridiculous claims are everywhere on the tube, social media, the supermarket and old-fashioned billboards. Anecdotes and celebrity testimonials have in many cases replaced evidence-based medicine in our popular culture. Diet, nutrition and medical claims are thrown together in an olio of nonsense of false promise and false hope.

Problems with Western Medicine

Let’s pause here a moment. Before ripping further into the obvious drawbacks of voodoo medicine, that is, any medical claims absent substantiating data, let’s first emphasize that of course evidence-based medicine (often called western medicine) has its own set of serious problems and significant limitations. Clinical studies can be and have been tainted by pharmaceutical company sponsors or by doctors with financial interests in the outcome; negative data can be buried or manipulated; drugs shown to be safe in small trials can turn out to have significant or even deadly side effects in a broader population; treatment can lead to addiction; and interactions among different drugs can be hazardous. Biology is complex, and our understanding of disease incomplete, meaning that treatments are often hit or miss or luck of the draw rather than based on first principles. Perhaps the biggest flaw with modern western medicine, though, is that we have created a false expectation that our ills can be cured with a pill when it fact the cure more often lies in making difficult lifestyle changes. Smoking, lack of exercise and overeating come to mind. But these flaws in modern medicine are, in theory, amenable to improvement because the foundation is evidence-based. With scrutiny and reproducibility comes an accountability that will eventually expose weaknesses to be addressed. Or at least that possibility exists, which is not the case for claims that are made with no attempt at rigorous evaluation — like cupping.

The Allure of False Hope

Cupping can be traced to ancient Chinese practices used ostensibly to treat a variety of ailments including arthritis and muscle soreness. There is no credible clinical evidence that cupping is anything more than a placebo — or one big hickey — with no medical benefit at all. And consider this question — did you see any of the Chinese athletes doing cupping therapy? Think about it. Perhaps if this ancient Chinese treatment really worked over millennia we might see Chinese athletes partaking of its benefits?

Like their cousin cupping, faddish cryotherapy and chelation also offer an alternative to actual medicine. Chelation, which has a legitimate application in treating acute heavy metal poisoning, is sold instead as a cure or treatment for arthritis, hormone imbalances, and heart disease, which unscrupulous practitioners attribute to “heavy metal toxicity” or some other false claim about why chelation is beneficial. No scientific evidence supports this. All of these claims are unproven. The same applies to cryotherapy (or more faddishly whole body cryotherapy, or WBC), touted as a way to slow aging, improve sleep, enhance athletic performance and reduce various pains. There is not a shred of credible scientific support for these assertions. This list goes on and on: Ayurvedic medicine, aromatherapy, homeopathy, shamanism, naturopathy, Hopi Indian ear candling, Sekkotsu, Christian faith healing, stem cell therapy, probiotics, treatment for systemic “inflammation”...

These therapies and treatments all share the same fatal flaw; none has undergone rigorous clinical studies to determine safety and efficacy. In the absence of such trials, it cannot possibly be known if the drug or treatment is effective, if there will be serious side effects, if it will actually make the condition worse, or it will interfere with drugs or treatments that would otherwise help. Wishful thinking is not a viable treatment plan. In the absence of rigorous evaluation, you simply cannot know if your favorite treatment or supplement works no matter how many convincing testimonials you hear or how many anecdotes you may read. You or Grandma or Aunt Tilly or your best friend are just making it up based on lore and hearsay, no different than randomly going into a supermarket, picking out a package of peas and claiming that eating half a bag a day (but only if eaten at noon) will cure arthritis. The claim is convincing if the familiar face of a celebrity testifies that eating a bag of peas each day at noon will cure your ills or if an actor dressed as a doctor, removing a pair of glasses to simulate intimacy, solemnly attests to the benefits of pea eating. But testimonials and anecdotes do not make the claim any more valid. You might think chelating works because someone you trust told you so — but you are doing nothing different than picking out that bag of peas.

Intersection of Voodoo Diet and Medicine

Claims surrounding nutrition are equally noxious. Of all the voodoo treatments mentioned, my personal favorites are those meant to address the curse of “inflammation“ because these claims are the perfect confluence between voodoo medicine and diet. Here is a typical claim:

“Inflammation controls our lives. Have you or a loved one dealt with pain, obesity, ADD/ADHD, peripheral neuropathy, diabetes, heart disease, stroke, migraines, thyroid issues, dental issues, or cancer? If you answered yes to any of these disorders you are dealing with inflammation.”

Well, no, inflammation does not control our lives. Like many others, this author claims inflammation is responsible for a huge range of maladies, ranging from Alzheimer’s to lupus to stroke to fibromyalgia; I counted 30 on this site. This is nothing but cringe-worthy. Yes, inflammation is terribly important, and is associated with disease. But the oversimplification and weak link to biology that we find on sites like these are misdirection from understanding what is actually happening in our bodies. Such misunderstanding leads to odd nutritional or medical recommendations that are useless at best or dangerous at worst.

We are awash in a sea of these crazy and exaggerated claims about inflammation that have taken root in popular culture, as even a quick Google search reveals:

Chronic inflammation is the root cause of many serious diseases.” No it is not; it is an important step, but one of many, in the progression of diseases generally caused by bad habits.

Inflammation is the cause of nearly all disease.” Wrong at every level; there are many diseases not associated with inflammation, and it is not typically the cause of disease. Rather inflammation is a pathway to pathology shared across many diseases.

Ginger and turmeric have been shown to have anti-inflammatory properties.” I love ginger and turmeric, but there is scant epidemiology to support the claim. It is just wishful thinking and the kind of bogus claim that distracts us from reality.

Excess sugar intake will contribute to inflammation. It’s not just the obvious sugar but also the hidden sugars.” There is no such thing as hidden sugars; and sugar itself has nothing to do with inflammation, other than adding calories, which in excess we know can cause inflammation.

Phytochemicals - natural chemicals found in plant foods... are also believed to help reduce inflammation.” There is no evidence for this statement. Of course, eating plant rather than animal products would reduce saturated fat intake, which in excess can cause inflammation. Cyanide is a natural chemical found in plants so the endorsement here is not ringing.

Inflammation has also been linked to unbalanced levels of certain hormones, such as estrogen, progesterone, and testosterone. That’s why chronic inflammation often inflicts menopausal women, causing conditions like osteoporosis, weight gain, and adult acne.” This claim is not substantiated by any serious clinical research. None.

Foods that combat inflammation include tomatoes, green leafy vegetables and nuts like almonds and walnuts.” Well, no, that is not true at all. These foods simply do not promote inflammation, which is not the same as combatting it. Avoiding rotten food is not the same thing as treating food poisoning.

Monica has done exhaustive research on the nutritional components of 1,600 common foods, and rated them according to scientifically validated factors related to inflammation.” Well, scientists would be surprised by this since there are no “scientifically validated factors related to inflammation.” Just foods with or without saturated fats, which we know in excess can lead to inflammation. This does not require “exhaustive research.”

Voodoo Nutrition and the Curse of Supplements

Atkins, Dean Ornish, the Zone, South Beach, Glycemic Index... this list of fad diets too is nearly endless. Grocery stores sell magazines shouting out blatantly false claims that promise to help readers “lose weight like a teenager,” “lose belly fat,” “lose 11 lbs a week,” and “fill up on fat-burning super foods.” We are sold hormone supplements, told the benefits of “anti-inflammatory foods” and promised results if we only would take acetyl coenzyme A. These promises cannot be kept because they defy the simplest laws of biology and physics.

Dr. Oz has on his website a section entitled, “The Top 10 Fat-Burning Foods.” This is what the FDA and nutritionists say about fat-burning foods: there is no such thing. Dr. Oz is conning you, feeding you pure nonsense, selling miracle cures no better than snake oil vendors of old. FDA says, “Consumers should know that there is no such thing as a fat-burning pill.” Just to be clear, the FDA adds further about fat-burning foods that, “No substance has ever been shown to actually do this.” It is a big lie, a scam.

People daily pop, drink and chow down on nutritional supplements with great abandon — without the slightest evidence that any of them have any potential benefit. But things are worse than that; not only do you not know if the supplement you take has any health benefit at all, you actually don’t know if you are taking the supplement you intend. You may well be taking something detrimental to health or something potentially healthy but in unsafe doses. This from an expose in the New York Times:

Among the attorney general’s findings was a popular store brand of ginseng pills at Walgreens, promoted for “physical endurance and vitality,” that contained only powdered garlic and rice. At Walmart, the authorities found that its ginkgo biloba, a Chinese plant promoted as a memory enhancer, contained little more than powdered radish, houseplants and wheat — despite a claim on the label that the product was wheat- and gluten-free. Three out of six herbal products at Target — ginkgo biloba, St. John’s wort and valerian root, a sleep aid — tested negative for the herbs on their labels. But they did contain powdered rice, beans, peas and wild carrots. And at GNC, the agency said, it found pills with unlisted ingredients used as fillers, like powdered legumes, the class of plants that includes peanuts and soybeans, a hazard for people with allergies.

The Times is not alone in their summary findings, as we see from an article from Consumer Health Choices:

Supplement manufacturers routinely, and legally, sell their products without first having to demonstrate that they are safe and effective. Unlabeled ingredients found in many supplements are: bitter orange, chaparral, colloidal silver, coltsfoot, comfrey, country mallow, germanium, greater celandine, kava, lobelia, and yohimbe. The FDA has warned about at least eight of them, some as long ago as 1993. Of the more than 54,000 dietary supplement products in the Natural Medicines Comprehensive Database, more than 40,000 have no level of safety and effectiveness supported by scientific evidence.

Next time you have an urge to take fish oil, ginger and ginkgo biloba, just pop some peas into your mouth; there is no evidence one is more healthful than the other.

There is no room here to debunk the ocean of nonsense we encounter daily; this small sample of crazy is not even the tip of the tip of the iceberg. The voodoo surrounding probiotics and hormone supplements for example is each in itself a blog, or book. But understand that unless you restrict your intake of drugs and supplements to those proven to be effective and safe through rigorous scientific evaluation, you are just randomly putting stuff in your mouth. You should stop doing that. And Michael Phelps should stop cupping; it is embarrassing.

EXTRACTS: "At a time when the struggle between authoritarianism and democracy is so intense, if not fateful for the future of democracies, NATO and the EU must warn these countries [Editor's note: Poland and Hungary, EU and NATO, Turkey NATO] that they are on the precipice of being kicked out if they do not change their governing practice. They must be required to restore the principles of democracy by upholding universal human rights and abiding the rule of law, or else they will forfeit their membership and suffer from the consequences of their crimes." ------ "A narcissistic leader, such as Trump, whose hunger for power seems to know no limit, has happily sacrificed the good of the country on the altar of his twisted ego. America’s democracy cannot be repaired unless he and those who helped him are held accountable and face the weight of the law."

EXTRACT: "Many people who go through intense trauma, for example, become deeper and stronger than they were before. They may even undergo a sudden and radical transformation that makes life more meaningful and fulfilling. Indeed, research shows that between half and one-third of all people experience significant personal development after traumatic events, such as bereavement, serious illness, accidents or divorce. Over time, they may feel a new sense of inner strength and confidence and gratitude for life and other people. They may develop more intimate and authentic relationships and have a wider perspective, with a clear sense of what is important in life and what isn’t. In psychology, this is referred to as “post-traumatic growth”. "

EXTRACT: "Notably, Murdoch thinks that really knowing or understanding another person is a difficult task: “It is a task to come to see the world as it is”. According to the Freudian psychology Murdoch subscribes to in The Sovereignty of Good, humans are prone to “fantasy” – refusing to face the truth because it can damage our fragile egos."

EXTRACT: "People do not believe false information because they are ignorant. There are many factors at work, but most researchers would agree that the belief in misinformation has little to do with the amount of knowledge a person possesses. Misinformation is a prime example of motivated reasoning. People tend to arrive at the conclusions they want to reach as long as they can construct seemingly reasonable justifications for these outcomes."

That was 58 years ago." -----"Mark my words: ...... No one who remembers 1963 will live to see the US government admit the full truth about Kennedy’s murder. And the American people’s faith in democracy will continue to fade. There is only one way to prevent this, and that is to release every record, withholding nothing – and to do it now."

EXTRACT: "..... we may defy the warnings of modern medicine, convinced of our own superiority. Researchers at the University of Chicago Divinity School reported half of their participants, all of whom indicated some religious affiliation, agreed with the statement “God will protect me from being infected”. To cope with our dread of death, we delude ourselves into thinking we are invincible: death might happen to other people, but not to me."

EXTRACT: "Wes Anderson’s new film The French Dispatch is about the final issue of a magazine that specialises in long-form articles about the goings-on in the fictional town of Ennui-sur-Blasé. The film is an anthology of shorts representing three of the articles. A piece by the magazine’s art critic (Tilda Swinton) explores the life and late success of the abstract artist Moses Rosenthaler (Benicio Del Toro). Talented from a young age, Rosenthaler pursued art with a dogged determination that drove him to slowly lose his mind." ---- "Like everything else, mental illness is understood within the context of its time. In their study of melancholy and genius Born Under Saturn, the art historians Margot and Rudolf Wittkower show how Renaissance artists embraced mental alienation. This was shown by a withdrawn, slothful gloom. Such heavy sadness was considered both the symptom and the price of divine inspiration." ---- "Today, the association of creativity and mental illness often implies regression from an adult and orderly state of mind to one that is primal, impulsive, or infantile. The artist in Anderson’s film is such an example: he is noisy, impetuous, and extravagantly mad. And it is while he is at his “maddest” that he paints his best work." ---- "Here I explore the work of four painters whose work has been shaped by various mental illnesses, highlighting how the idea of the “mad artist” need not be tied up with a loss of control but rather a bid to gain it."

EXTRACT: "So much of Succession holds a mirror to real life, and the way that Logan Roy’s hand-picked board members allowed these abuses to continue by turning a blind eye to them is a good example. We have just published research that shows that public companies whose directors are chosen by their CEOs are statistically more likely to be involved in corporate misconduct, along with various other shortcomings. So why does this happen, and what should be done about it? "

EXTRACT: "As the 25th James Bond film No Time to Die hits the cinemas, we are once again reminded of the way that disability is depicted negatively in Hollywood films. The new James Bond film features three villains, all of who have facial disfigurements (Blofeld, Safin and Primo). If you take a closer look at James Bond villains throughout history, the majority have facial disfigurements or physical impairments. This is in sharp contrast to the other characters, including James Bond, who are able-bodied and presented with no physical bodily differences. Indeed, many films still rely on outdated disability tropes, including Star Wars and various Disney classics. Rather than simply being part of a character’s identity, the physical difference is exploited and exaggerated to become a plot point and visual metaphor for villains" ----- "The British Film Institute (BFI) was the first organisation to sign up and has committed to stop funding films that feature negative representations depicted through scars or facial differences – a step in the right direction."

It is commonly used to treat decompression sickness (a condition scuba divers can suffer from), carbon monoxide poisoning,......" ---- "Blood flow to the brain is reduced in people with Alzheimer’s. This study showed increased blood flow to the brain in the mice receiving oxygen therapy, which helps with the clearance of plaques from the brain, and reduces inflammation – a hallmark of Alzheimer’s." ----- "The researchers then used these findings to assess the effectiveness of oxygen therapy in six people over the age of 65 with cognitive decline. They found that 60 sessions of oxygen therapy, over 90 days, increased blood flow in certain areas of the brain and significantly improved the patients’ cognitive abilities – improved memory, attention and information processing speed."

EXTRACT: "Hollywood for years called on Charles Boyer to typify one French look –  bedroom eyes, sly maneuverings, the dismissive look. A face of another type, the massive mug and narrow eyes of Charles de Gaulle, provides the same disdain of the foreigner but also a superiority based on his belief in his own destiny."

EXTRACT: "The burden of loneliness for older people is intimately connected to what they are alone with. As we reach the end of our lives, we frequently carry heavy burdens that have accumulated along the way, such as feelings of regret, betrayal and rejection. And the wounds from past relationships can haunt people all their lives."

EXTRACT: "Gardens help restore the ability to concentrate on demanding tasks, providing the perfect space for a break when working from home in a pandemic. Natural things – such as trees, plants and water – are particularly easy on the eye and demand little mental effort to look at. Simply sitting in a garden is therefore relaxing and beneficial to mental wellbeing."

EXTRACT: "Whether or not a person achieves remission, reducing blood sugar levels is important in managing the negative effects of type 2 diabetes and reducing risk of complications. But when it comes to choosing a diet, the most important thing is to pick one that suits you – one that you’re likely to stick to long term."
Aug 10th 2021
EXTRACT: "In our latest study, we show that by taking the microbiome from young mice and transplanting them into old mice, many of the effects of ageing on learning and memory and immune impairments can be reversed. Using a maze, we showed that this faecal microbiota transplant from young to old mice led to the old mice finding a hidden platform faster."

EXTRACT: "Fukuyama argued that political struggle causes history. This struggle tries to solve the problem of thymos – an ancient Greek term referring to our desire to have our worth recognised. This desire can involve wanting to be recognised as equal to others. But it can also involve wanting to be recognised as superior to others. A stable political system needs to accommodate both desires." .... "Counter-dominant spite can weaken liberal democracies. During the 2016 Brexit referendum, some people in the UK voted Leave to spite elites, knowing this could damage the country’s economy. Similarly, during the 2016 US presidential election some voters supported Donald Trump to spite Hillary Clinton, knowing his election could harm the US. "
Jul 31st 2021
EXTRACT: "If we want to live in a world that is good for pollinators, as well as the rest of us, big changes are needed in our environment, and our food system. This is why many beekeepers change their diet and their shopping, eating more locally grown vegetables that aren’t treated with pesticides. ...... Being willing to buy fruit and vegetables that may have the occasional insect living in it is better for us and for nature. To live more harmoniously with the natural world, we need to relax about larvae in the lettuce and slugs in the spinach."

EXTRACT: "You’d think our brush with mortality through the pandemic would have brought some of this home to us. You’d think it would give us pause for thought about what really matters to us: the kind of world we want for our children; the kind of society we want to live in. And for many people it has. In a survey carried out during lockdown in the UK, 85% of respondents found something in their changed conditions they felt worth keeping and fewer than 10% wanted a complete return to normal."
