Well the trust has to be earned by a history of proven visibly good outcomes. Never forget that there is a long history of cases where the established scientifically accepted ideas were actually harmfully wrong, particularly in the medical arena. In the USA in particular, medical practice is far from a benign charity, so people are right to question. One example: I had a tonsillectomy when I was a kid. No actual evidence that this is good medicine..

On the other hand, I don't disagree that the level of misinformation is ridiculous. It's difficult to understand why someone would trust someone with a popular podcast so much more than licensed professionals. Maybe there shouldn't be censorship, but where are the medical malpractice claims against these people? I think it's all tied in with the general acceptance of the "these statements have not been evaluated by the FDA" supplement industry. As long as your supplement does not do too much direct harm, we allow it.
