Fair enough... But I've also worked within many of the federal government agencies so I say this from personal experience and knowledge. Many, I repeat, many agencies are compromised as far as objective or even honest data. In fact, FDA has a large testing facility about an hour from my house and I personally know numerous people (all scientists) who work there. Most would tell you that the industry is very incestuous....meaning that people constantly go back and forth between employment wise from FDA and the very companies they "approve" products for. Especially around the FDA there is a LOT of corruption. It should NOT be this way but we haven't had a functioning watchdog against corruption for decades. So just because FDA or any other government agency does not "codify" any particular claim does not always mean there is no substance to the claim.
BTW, I resigned from my government work last year because I couldn't tolerate the corruption any longer.
