I avoid erythritol because you have to use so much of it. With something like aspartame it’s so much sweeter than sugar per gram that even if it all converted to formaldehyde a few sodas would be nothing to worry about. But erythritol is 30% less sweet than sugar so they put a bunch in. And the full effects of a bunch of a not-very-metabolized substance haven’t been well-enough studied for me to not just get some other fake sugar thing instead.

As the other commenter said, though, this study had very small N.
