Why would L-glucose taste the same and have the same effects on mood, etc. if nothing in nature could interact with it? I am not an expert in chemistry or molecular biology, but that seems odd.
I was wondering if anyone would catch that! Yeah, it's definitely part of the "fiction" here. L-glucose can bind to some things, e.g. taste receptors. "Nothing in nature can interact with it" was definitely an over-simplification
