This term gets thrown around all the time. I was given a gift card for a massage for my last birthday (which was wonderful, by the way), and afterwards, the masseuse told me that I needed to drink lots of water that day because the massage had "loosened up toxins" and I needed to drink a lot to "flush them from my system." A while back, I was buying some fresh turmeric root at a local organic grocery, and a lady smiled at me in a friendly sort of way, and said, "Oooh, turmeric! It's wonderful at detoxifying the body!"
What gets me about the use of "toxin" and "detoxify" is that the people who use those terms so seldom have any idea about what particular toxins they're talking about. If I was just a wee bit more obnoxious than I am -- an eventuality no one should wish for -- I would have said to the masseuse and the lady in the grocery, "Can you name one specific chemical that massage and/or turmeric releases in my body that I need to be concerned about?"
Chances are, of course, they would not have been able to; even in supposedly informative articles in health magazines, they're just lumped together as "toxins." The word has become a stand-in for unspecified "really bad stuff" that we need to fret about even though no one seems all that sure what it is.
And then buy whatever silly detox remedy the writer of the article suggests.
This all comes up because of an article I read in Science-Based Medicine called "Activated Charcoal: The Latest Detox Fad in an Obsessive Food Culture," by Scott Gavura. In it, we hear about people dosing themselves with activated charcoal as a "detox" or "cleanse," because evidently our liver and kidneys -- evolved over millions of years to deal with all sorts of unpleasant metabolic wastes -- are insufficient to protect us.
No, you need "activated charcoal lemonade."
The problem here, as Gavura points out, is that activated charcoal is used in detoxification, so there's that kernel of truth in all of the nonsense. Actual detoxification, I mean, not this pseudoscientific fad-medicine horseshit; detoxification of the sort done in cases of poisoning. I know this first hand, because of an incident involving a border collie named Doolin that we once had. My wife and I had visited northern California, and dropped by the wonderful Mendocino Chocolate Company, makers of what are objectively the best chocolate truffles in the entire world. We bought a dozen truffles of various sorts and brought them home with us, babying them through our travels during high summer. We got them home successfully, and on the first day back...
... Doolin pulled the box off the counter and ate all twelve chocolate truffles.
As you undoubtedly know, chocolate is highly poisonous to dogs, so off Doolin went to the vet to get a (real) detoxification. One of the things they did was feed her activated charcoal. We found this out because on the way back home from the vet, Doolin puked up charcoal all over the back seat of my wife's brand-new Mini Cooper.
Doolin survived the chocolate incident, although she almost didn't survive our reaction to (1) the thousand-dollar vet bill, (2) black doggie puke all over the new car upholstery, and worst of all, (3) not getting our chocolates. Despite all that, she went on to live another six healthy years, thanks to modern veterinary science and the fact that she was cute enough that we decided not to strangle her.
But I digress.
So charcoal does have its uses. But you're not accomplishing anything by adding it to lemonade, except perhaps (as Gavura writes) having the charcoal absorb nutrients from your digestive tract, making whatever food you're eating less nutritious. Because charcoal, of course, isn't selective about what it absorbs -- it'll absorb damn near anything, including vitamins and other essential nutrients.
Facts don't seem to matter much to the alt-med crowd, however, and now there's charcoal everywhere. Over at the webzine Into the Gloss, writer Victoria Lewis tells us about taste-testing a bunch of different charcoal drinks, and her analysis includes the following insightful paragraph about "Juice Generation Activated Greens":
I decided to drink this ultra-vegetable-filled (kale, spinach, celery, parsley, romaine, and cucumber) juice for breakfast. It tasted exactly like a super green juice—a little salty but otherwise, totally normal. I did end up eating some granola afterwards (juice diets have never been for me), but this one felt good and extremely healthy.
But of course, since now we have renowned nutritionists like Gwyneth Paltrow getting on board, the whole "charcoal juice cleanse" thing is going to take off amongst people with more money than sense.
Makes me feel like I need to go eat some bacon and eggs, just to restore order to the universe.
To the layperson, there's something odd about physicists' search for (amongst many other things) a Grand Unified Theory, that unites the four fundamental forces into one elegant model.
Why do they think that there is such a theory? Strange as it sounds, a lot of them say it's because having one force of the four (gravitation) not accounted for by the model, and requiring its own separate equations to explain, is "messy." Or "inelegant." Or -- most tellingly -- "ugly."
So, put simply; why do physicists have the tendency to think that for a theory to be true, it has to be elegant and beautiful? Couldn't the universe just be chaotic and weird, with different facets of it obeying their own unrelated laws, with no unifying explanation to account for it all?
This is the question that physicist Sabine Hossenfelder addresses in her wonderful book Lost in Math: How Beauty Leads Physicists Astray. She makes a bold statement; that this search for beauty and elegance in the mathematical models has diverted theoretical physics into untestable, unverifiable cul-de-sacs, blinding researchers to the reality -- the experimental evidence.
Whatever you think about whether the universe should obey aesthetically pleasing rules, or whether you're okay with weirdness and messiness, Hossenfelder's book will challenge your perception of how science is done. It's a fascinating, fun, and enlightening read for anyone interested in learning about the arcane reaches of physics.
