I understood your point, but I thought it was far to generalized. I don't think there is conclusive research to talk about mortality rates, quality of life, etc that shows that splenda is unhealthy or worse than stevia or anything else. I don't think any can be labeled a "toxin." If there were definitive proof that either of these things were "unhealthy" then I would agree with you.
Hot pepper consumption in South East Asia can lead to stomach cancer over time...peppers aren't considered toxins, they're natural food products, but they can lead to health problems even in moderate doses. Should we label them as unhealthy and bash the consumers of them?
I think mental health is important...and mental health & physical health can be linked in many ways.
It might not be unreasonable, but it might be. (For example, if I take 200mg DNP for 365 days I MIGHT not encounter health problems...but I might...however if I take 1.5g for three days, I could die...yes DNP is an extreme example, but it's just to highlight that lower doses over longer periods does not necessarily equate to short term, ridiculously high doses).
That's my problem with the whole point...there are a bunch of conclusions and guesses, no actual data. So to simply label something as an unhealthy toxin and its users as potentially careless? That I have a problem with, especially given the nature of this board.
