Yeah, people would eat many Xs if they tasted like Ys ...
Some people should really go in a no (added) sugar diet for a bit, even things like lemons become sweet after a few weeks of no junk/sugary food. I've witnessed people dipping slices of apple in white sugar so I guess I shouldn't be surprised.
Ten years ago I would routinely get a 20+ oz soda with my meal and that feels unimaginable to me today. Part of that is just me getting old. Consuming a bunch of sugar today leaves me feeling hungover tomorrow.
I guess I'd also worry that it would be hard to cook and eat because it adds an unusual dependency between ingredients: normally you don't worry that your ketchup on your hot dog will later make your cake taste too sweet.
This is not different than some people thinking that a colagen cream magically puts inside the big molecules that are just extended over the skin, or that you can take iron in your diet just touching a iron bar.
