pretty much the same statement is on the notmilk site, so maybe they started it?
eta:yeah, looks like the same statement to me (quick look) so that'll be by mr robert cohen, their executive director. still curious as to where the OP's email came from though- i wonder if they have a mailing list. hmmmmm.
eta: i'm also curious as to why a site trying to stop people using dairy milk, would use such unappealing discriptive words to describe a compound in soya milk- you'd think they'd word it in a nicer, friendlier, more 'natural product' way, instead of adding the petrolchemical connotations in there- in the hopes of not putting people off soya milk and right back onto dairy milk, wouldn't you? or is notmilk anti soya milk too?
