Unfortunately, the FDA is part of the problem. Like the Iron Triangle of Defense contractors, there is a revolving door between industry lobbyists, government officials, and company heads. It is a never ending loop of corruption. Through government agencies such as NIH and its offshoots, this cabal controls the flow and funding of research at the behest of financial interests in the agra/pharmaceutical industries. Journals such as Lancet, JAMA, and NEJM, among others, are also part of the system that selectively publishes flawed data while at the same time censors other offerings.  It is hard to find legitimate unbiased research that is not under the thumb of this cabal of self interests cloaked as serving the public good. He who controls the money has the power. Research is expensive and the carrot of public funding is tempting and is unfortunately necessary for most research to even exist. It is usually not the researchers themselves who are dishonest, but those who are the gatekeepers of the published data. They take credit for work mostly done by others who remain nameless or even have their work stolen. People do not usually think of science as being less than noble, but it is a dog eat dog system like any other. People are often seen by the cabal as simply a means to an end whether they are unsuspecting guinea pigs or expendable risk collateral on the path to financial or positional gain. Researchers who buck the system will find themselves many times not only without a job, but persecuted and blacklisted - and in some cases, dead. Whistle-blowing is not tolerated and punishment for violation of the code of silence is met with swift punishment. Not a good place to be if you are just trying to survive like everyone else. The researchers, as well as the rest of the public, are often victims caught in this web of greed and power.
