How Can Facts Compete With Fads?

A couple of years ago beet juice was all the rage. Promoters sold a powder to dissolve in water.  They called it a circulation super-food. They backed up their claim with a pile of testimonials but scant scientific evidence; except that beets are vegetables, and vegetables are healthy. Does that make any vegetable a super food?

Well, step aside beet juice. It’s time for celery to take a turn.

How do we know celery juice is the latest super food? – Testimonials, of course! Says one article, “Celery juice is everywhere. So much so, that the two New York Whole Foods locations I’ve gone to in the past two weeks have been out of celery” as people buy it in bulk to take it home and run it through the blender.

These are not ordinary testimonials. Apparently the fad start when the Medical Medium (MM not to be confused in any way with MD) told his thousands of on-line followers that celery juice was “one of the most powerful and healing juices we can drink.” Since then it has been “rising in popularity within the health and wellness world” with tens of thousands of personal endorsements on Instagram. Among them are celebrity/influencers including Gwyneth Paltrow, Kim Kardashian and Debra Messing.

When I looked up articles about celery juice, though, most that I found said that those claims are false. This one begins with a headline, “Celery Juice ‘Benefits’ Are Total B.S., According to Nutrition Science.” The claims of it reducing chronic inflammation are grossly exaggerated. It doesn’t necessarily help with weight loss, because juicing any vegetable “will yield a higher concentration of sugar.” Any mention of detox should automatically be a red flag for anyone with an ounce of nutritional common sense.

Another website mocks the whole idea of the detox claim saying, “this entire celery juice trend is the epitome of bullshit pseudoscience.” It’s all about being a member of the super cool crowd that crowed about kale until celery juice was declared the new kid in town. It’s more about a need to belong, than a desire to be healthier.

Another reason people are drawn to juice fads is the convenience. The answer to not having time for fruit and vegetables is to grab a bottle or tumbler of the liquid equivalent, but it’s not really equal. The process of juicing compromises some of the nutritional value because it loses the beneficial fiber you find in raw veggies.

And Americans don’t get enough fiber.

This BBC article argues, “people who eat more dietary fiber are actually feeding their gut microbiome,” and “fiber leads to greater satiety, less insulin secretion, and more short-chain fatty acids, which all amounts to one thing: less body weight.”

Studies show that “those who had the highest intake of fiber or total fiber actually had an almost 80 percent greater likelihood of living a long and healthy life over a 10-year follow-up, [and] were less likely to suffer from hypertension, diabetes, dementia, depression, and functional disability.” 

This fiber, that BBC calls a lifesaving food, is easily available. “You find it in fruit and vegetables, some breakfast cereals, breads and pasta that use whole-grains, pulses such as beans, lentils and chickpeas, as well as nuts and seeds.” That’s whole fruits and vegetables, not the ones that have been run through a blender.

Once again, that’s the truth about another so-called super food. But how does the truth compete with celebrities, influencers and self-declared wellness experts with thousands of Instagram followers but no formal training in nutrition or science? All these fad diets are based on testimonials and endorsements that appeal to the emotions without any scientific basis with the sole intent of selling to gullible people their books, products and other secrets of good health.

Ancient Chinese Folly

There is something fascinating about ideas that are ancient and Chinese. They are in the same category as all-natural, sustainable and organic. People take them on faith, feeling that research is unnecessary, while risking the loss of time and money; and sometimes putting themselves at risk.

Take acupuncture for example. I am always skeptical of treatments that boast a cure or relief from multiple conditions. Just one example is listed here. “Health benefits of acupuncture include relief from chronic pain, arthritis, anxiety, insomnia, depression, migraine, nausea, postoperative pain, and obesity.” 

This other website adds to the list: nausea, sciatica, sinus congestion, stress, tinnitus and tobacco addiction. But then they go on to describe several recent research results in not very glowing terms. In 2017 authors reported limited evidence that acupuncture is modestly effective for acute low back pain. A 2016 review of 22 previously published trials concluded that adding acupuncture to standard treatments for migraines “may reduce the frequency of episodes, however the size of the effect is small when compared to a sham acupuncture treatment.” A 2016 review of 12 trials found that it may help people with frequent tension headaches. And another analysis “it appeared to provide only short-term(up to 13 weeks) relief” for people with chronic knee pain.”

One puzzling comment was that after the treatment “some people feel relaxed (or even sleepy), while others feel energetic.” One treatment with opposite outcomes may indicate a strong placebo effect.

Not many sources list the side effects of acupuncture. Since it’s ancient and Chinese many will automatically assume that it is only beneficial. But the treatment “can cause serious adverse effects, such as infections, nerve and blood vessel injury, complications from needle breakage or remnant needle pieces, punctured organs, central nervous system or spinal cord injury, hemorrhage, and other organ and tissue injuries resulting in death. Punctured pleural membranes around the lungs can lead to collapsed lungs.”

A study from China in 2015 claiming acupuncture is effective for treating the symptoms of angina was published only a few weeks ago. It received a harsh critique based on the time delay, lack of studies replicating the result, failure to use a double-blind design, the subjective nature of the results and that all authors were affiliated with schools of acupuncture or Traditional Chinese Medicine.

A report from 2013 states that “after decades of research and more than 3000 trials, acupuncture researchers have failed to reject the null hypothesis, and any remaining possible specific effect from acupuncture is so tiny as to be clinically insignificant.” Since then as we see above, evidence of effectiveness continues to be weak.

I always wonder why so many people, who mock those that don’t agree with them on climate change as being as unscientific as flat-Earthers, unquestioningly put their faith in these treatments and cures, some even crazier and more dangerous than acupuncture.

The BBC reports on a case from the Journal of Obstetrics and Gynaecology Canada of a 62-year-old woman who, on the advise of her traditional Chinese doctor, sustained severe burns when she tried vaginal steaming in an attempt to avoid surgery for a prolapsed vagina. “Vaginal steaming, which involves sitting over a hot water and herb mix, has seen a growth in popularity” and is “now available at some salons and spas.”

The practice began to gain popularity in 2010 and has been endorsed by Gwyneth Paltrow as a detox and cleansing treatment – those two words alone should scare off clear thinking Americans. Last year Chrissy Teigen, who tweeted under a picture of herself trying it, “no I don’t think this works but it can’t hurt right?” No, wrong! Ask a doctor rather than a model or movie star and you will get the opposite answer on all claims.

Once again, lapses in critical thinking are so obvious. There is no such thing as alternative medicine. There is only medicine that works and medicine that doesn’t. In the war between science and fairy tales, the fairy tales are winning.

People, People, People...

And now back to one of my favorite topics, Americans being duped by celebrities or celebrity endorsements into buying things they don’t need, things of little value or things that are potentially dangerous. On an individual basis it’s sad, and on a societal one it’s very discouraging.

If your car broke down, would you have it towed to the local TV station for the news anchor to look at – even if his or her hobby happened to be car repair? Probably not.

If your toilet backed up would you invite the local golf pro over to fix it – even if he had an engineering degree and an interest in plumbing? I don’t think so.

If you had a health question, would you seek advice from a Hollywood star instead of a health professional? The answer should be the same, but then how does Gwyneth Paltrow get away with it?

She holds health summits for her Goop brand charging $1500 per person, “despite repeated debunkings of her brand’s health claims, and piece after piece arguing the nonsense she sells is nothing more than snake oil.” This article comments on a new partnership with Netflix to push her products. In addition to her original lifestyle-and-wellness business, she owns a clothing manufacturer, a beauty company, an advertising hub, a publishing house, a podcast producer and several others. According to the New York Times, her brand is worth $250 million!

By playing on her celebrity status, Ms. Paltrow is reeling in customers by the boatload pedaling what many sources refer to at pseudoscience and misinformation. Errors in fashion may be OK; customers risk nothing more than possible derision. But when it comes to someone’s health, outcomes can reach beyond a waste of time and money to become dangerous or even fatal. 

Take for example one of the ten most read entries on the Goop site. “In consultation with Dr. Alejandro Junger, we created a week-long detox menu to recover from post-holiday indulgence.” Likely no one ever looked up the doctor’s credentials or questioned the efficacy of his advice before venturing into this experiment in self-medication. Unfortunately, as I’ve often written before in detail, detox plans are both unnecessary and dangerous. 

In other examples related to health, Goop continues a war on science with claims that are so outlandish that the whole thing could be mistaken for satire. But it’s not, and it’s very problematic. Dr. Timothy Caulfield, Canada Research Chair in Health Law and Policy at the University of Alberta, is a frequent critic. “Assuming this isn’t performance art, the increasing popularity of companies like Goop is a cause for legitimate concern. Despite the best efforts of journalists and doctors, the debunkers are not winning the wellness war. Indeed, there is evidence that the trust people place in traditional sources of science is eroding.”

 Or as Vox put it just last summer, “Goop has been called out for bullshit over and over. But the brand seems to be stronger than ever.” Many agree that such opposition has just strengthened the brand among those already made suspicious of traditional medicine by so many other snake oil enterprises – basically appealing to those people who have sent their critical thinking on a long vacation.

It’s ironic that science brings us smart phones and the Internet so celebrities can use them to profit from the ignorance of people by selling and/or endorsing junk-science treatments and fake cures. It demonstrates the truth of what Isaac Asimov said many years ago: “The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.”
