Artificial sweeteners is one of the reasons I'm not obese. You can quote me all the studies you want, diet coke is not a gateway drink to regular coke, and splenda on my black coffee doesn't make me crave a caramel macchiato.
Aspartame gave me terrible headaches. Then I became diabetic. Turns out by that time sucralose was more popular. It doesn't give me headaches and it tastes fine. After so long of having sucralose, I can now tolerate aspartame. Still gross though.
I can taste all of the artificial sweeteners. My spouse uses them constantly and they taste sideways to me. My partner doesn't taste much of a difference so If we ever get drinks mixed up I'm the poison tester.
The only way to get them to taste fine enough is by using a mixture of a few different ones. I'm sure my experience is similar to people who have the cilantro soap thing.
I think high fructose corn syrup taste like literal poison. I can taste it in anything and everything it's in. Funny thing though. Your tastebuds acclimate, and you get used to flavors (either HFCS or Aspartame). I still struggle with stevia, sometimes, but it's far easier to look past than high fructose corn syrup.
My partner has been doing low carb for around 5 years now. I'm assuming it takes longer? I usually try everything they make. From ice cream to syrups to cakes.
Real talk though, I love xanthan gum. I know it's garbage.
Artificial sweetners do taste "off" to me, but tastebuds can acclimate to it. The rest of my digestive system? Not so much. Let's just say there is a reason it is pronounced ASS-partame.
