Well the aspartame thing is highly "googleable" reams and reams of contra indications regarding it's consumption and NO it is NOT banned in the US ( or the UK) despite it causing everything from cancer, birth defects, to blindness and a breakdown of the central nervous system.
go through your cupboards at home and you'll find it crops up everywhere ( where you'd not expect it to) either listed as Aspartame or phenylalanine. A reasonably good book for unleashing things you'd not want folk to know if you were the people concerned is
You Are Being Lied To
The Disinformation Guide to Media Distortion,
Historical Whitewashes and Cultural Myths
as it has very detailed references as to where they get their facts.
I know nothing about the Triads thing however.
