Ages ago, I used to work for the company that made Splenda, a popular artificial sweetener that is basically sugar that’s chemically altered so that it mostly passes through your digestive system instead of being absorbed. My job at the time was to read over and sometimes respond to all sorts of consumer complaints. And as such, I got to see depressing examples of how even adults can be grotesquely ignorant of everything from chemistry to basic material physics.
For instance, we got all sorts of people writing in horrified that Splenda contains chlorine, which is dangerous and caustic gas!!!!! Now, personally, I have no idea whether Splenda is 100% safe healthwise (but then, I have no idea whether natural sugar is 100% safe healthwise either). But I do know that the hysteria over it containing chlorine, which is still being pushed by alt-med “naturopaths” (i.e. people who irrationally believe that chemistry done by human beings is somehow different and more dangerous than chemistry done in nature), is pure poppycock. Our standard response at the time was “well, while it’s true that there are chlorine atoms in the sucralose molecule, the exact same atoms, in a far higher proportion by weight, are found in salt (NaCl)!”
Today, I still just stand in amazement that anyone could be so ignorant of basic chemistry as to think that molecules somehow necessarily have all the same properties as the atoms they contain. Heck, most of the basic atoms found in organic molecules are extremely toxic in ionized or pure elemental form: raw potassium or sodium, for instance, explode when they get wet. Heck, the very things which the chlorine atoms replace in the sugar molecule, Hydroxyl groups, would be crazy bad for you en masse in their free-floating ionized form.
For goodness sakes: the whole takeaway point of molecular chemistry is that the affects and properties of molecules and elements depend crucially on their exact configuration and the sorts of bonds they can make or break. I can understand most people not remembering the exact details of things from high school chemistry, but you’d think they’d at least retain some sense of the the basic idea.
Anyway. The second most common Splenda complaint was from folks who were utterly outraged that their box of Splenda didn’t weigh pound for pound like sugar. Now, it says pretty clearly on the box that Splenda measures “cup for cup like sugar,” and this is done so that people can directly substitute it for sugar in a recipe (Splenda, unlike most other artificial sweetners, holds up taste-wise in baking applications pretty well). Since the Splenda molecule is far sweeter on the tongue than sugar, it takes far less of it to match the same sweetness. This means that it would be flatly impossible for Splenda to match sugar along all three important variables at once: sweetness per volume per pound. The solution was simply to make Splenda exactly dense enough to match sweetness and volume.
Unfortunately, by law, the package also has to say something like “equivalent sweetness to 2 pounds of sugar.” People were apparently looking at that statement, looking at the actual listed product weight, seeing that they were different, and then concluding that they had been ripped off. Somehow, the phrase “equivalent sweetness” never made them stop and think about an alternative explanation.
Of course, having to explain things like the difference between weight and volume to adults is embarrassing no matter how politely you try to phrase it. Sparing their feelings, we mostly just offered to send people more free Splenda.
Speaking of which, my favorite consumer complaint was from a guy who wrote in threatening to sue us because we had sent a free sample of Splenda to his house, addressed to his then ex-wife. His current girlfriend got pissed off when she saw it and supposedly left him.
Not knowing what else to do, I simply wrote back our standard form letter response, which was basically “Well, we hope you at least enjoyed your Splenda, and we’d be happy to send you more Splenda!“
