CW: Discusses diets, food, BMI and commonly held misconceptions. If you like to believe everything you think is 100% correct, are prone to all-or-nothing thinking, or want your beliefs reinforced on all things health and fitness, you may not want to read this post.
I think I’ve reached the point that I need a pseudoscience trigger warning. I am finding myself angry to the point of nearly yelling whenever someone mentions their “love languages” like it’s anything more than a convenient construct. The other day, I wanted to ram into the minivan ahead of me on the freeway with their anti-vaxxer bumper sticker. If I have to listen to one more Republican politician espouse a conspiracy theory as if it were the truth, I might remove my car radio and throw it out the window.
I am a science teacher, and trained to think like a scientist. I believe in facts and research and data. And we live in a world in which science is discussed with such ignorance that the presence of a single study is enough to sway/reinforce the incorrect beliefs of people. No one discusses the preponderance of the data. No one is asking for the big picture data over time. And this lack of scientific literacy is hurting people.
I live in a city that doesn’t fluoridate its water because a majority of the voting public considers it unsafe. These voters aren’t thinking about the consequences for the uninsured and underinsured children who don’t receive regular dental care and benefit measurably from fluoride treatments. Instead, there’s a mindset that “impurities” or “chemicals” are “toxins” and therefore things we should all want to avoid. This is pseudoscience.
The debate about organic produce focuses on these fears of “toxins” as well, instead on the very real dangers of overproduction, potential lack of sustainability or concerns for workers’ rights. And don’t get me started on the fear of GMOs. I am concerned about GMOs, but not for any personal health reasons–rather, I don’t like the idea that we are reinforcing monocultures, cloned products with no biodiversity designed to be sprayed with levels of chemicals potentially unsafe from the workers doing the work and the communities that live downwind. On the other hand, if we can design GMO versions of staple foods that reduces environmental degradation while providing sufficient nourishment for the food insecure nations of the world, who am I to say they can’t have it? There is NO evidence that these products are dangerous to human health once they reach the dinner table, and yet that is the only discussion we are hearing. We can’t have a meaningful debate about the real costs and benefits of these products when we aren’t even agreeing upon the basic facts.
Want to get pissed off at some pseudoscience? Watch pretty much any of the food “documentaries” created since Supersize Me became a blockbuster. There you can learn the half-truths behind the values of juicing, eliminating sugar, paleo diets, vegan diets, Twinkie diets, McDonalds diets, and so much more. Look for the warning signs of pseudoscience as you go–are they using anecdotal data and individuals while avoiding comparing larger sample sizes? Do they ignore the facts that run counter to their arguments? Do they set up false dichotomies requiring an all-or-nothing comparison–the worst of the standard diet against the best/purest of the proposed diet? If so, consider this your pseudoscience trigger warning.
Health, diet and fitness culture is rife with this sort of pseudoscience. Every named diet ever formulated has some sort of “data” to argue that it is the best way to make you healthier, happier, and fitter. Every single one of them cherry-picks the data, jumps to conclusions outside the purview of the research, and uses logical fallacies like false dichotomies to “prove” their superiority. Their goal is to sell their books, products, and edible non-food meal replacement products, not to inform you. And every time a friend or family member of mine begins to starve themselves in a new way or to take outrageously expensive supplements, it pisses me off. I’m not angry at them, I’m angry at the liars shilling these products and false promises.
I’m angry at the diet and fitness industry for convincing so many people that it is exclusively their own fault for having a larger body and that the solutions are simple. I’m angry that people believe they need to go “on a diet” in order to live a healthier life in a body that more closely meets their needs. I’m angry at the lie that we should exercise to control our body size and the willful ignorance that avoids discussing the dozens of other actually good reasons for regular exercise, regardless of our body size. Commercials, paid spokespeople, and poorly written news reports that ignore this bigger picture really do deserve a pseudoscience trigger warning.
But of course, it is the nature of pseudoscience to not identify itself as such. It would lose some of its intended power if it had to remind you first that what they were about to say has limited evidence to support it.
But wouldn’t it be wonderful if these warnings existed? Imagine a world in which news broadcasters interviewing the latest fitness guru had to first announce, “Trigger warning, everything we’re about to say has limited or questionable data to support it.” What if dietary supplements came with a bold statement that said “we cannot prove that anything will happen when you take this pill, and maybe it will make things worse.” What if any time your friend/family member/colleague began to espouse how great it is to go Keto they found themselves first saying “there is absolutely no evidence that this is going to work for me long term, but I’m going to try it anyway.”
What if your doctor had to say, “Now, there’s mixed evidence that BMI has a causal relationship to other risk factors, it is only accurate as a measure of body fat percentage for about 60% of the population, and it’s commonly used to reinforce anti-fat stereotypes. Given all that, I’d like to discuss how much you weigh.”
Think of how much more empowered we would be if these warnings were expected and required. I am so sick and tired of hearing bullshit being espoused as fact. We live in an era in which genuine experts are distrusted and suspected of ulterior motives, in which confirmation bias is treated as an acceptable alternative to hard truths. People rely upon the news, doctors, experts and friends and family to help them sort through the data to make the best decisions for themselves and their health. We can’t make good decisions with bad data, and until we find another way to sort through the pseudoscience, I would appreciate a trigger warning.
