Yes, they may be established (if we're referring to the FDA and co). But they also say that such toxic poisons as aspartame, sucralose and MSG are safe. Therefore any credibility is out the window. The moment they admit that they've allowed their country and others to be poisoned for the past couple of decades (and longer) is the moment I'll start to accept them as a more reliable source. Until then...
And the book I'm referring to has been checked for accuracy by a leading doctor/professor, and is constantly backed up - as in, virtually every paragraph - with the names of leading scientists, doctors, and other professionals in the field, usually with notes on where to go and find the documentation or research she's talking about at whatever point. It's all there for you to go and look at yourself with plenty of citation and footnotes, plus an in-depth index of dozens of photocopies of some of the documents as well. It's not your average opinion-piece; it's a highly-detailed piece of research.
