The FDA is an affront to medical freedom in the US. Like all regulatory agencies, it has formed a cartel with the businesses it was implemented to regulate. We are left with mainstream medical knowledge subject to lobbyists. The FDA pushes flawed studies as irrefutable science, dangerous drugs, and a diet not suited to humans.
Private, voluntary certification companies like Underwriters Laboratories have an incentive to be honest, because they will go out of business if discredited. Likewise, pharmaceutical companies need the certification of an outside party to gain and keep the trust of consumers. The FDA should not be that party. Unlike the UL, it is a government bureaucracy that does not need to maintain a good reputation to stay in power.
To understand a program you must become both the machine and the program.
