I'm all for science ... until the scientists start blatantly lying. Then I have to decide which scientist is lying to me and which one isn't. Perfect breeding ground for conspiracy theories when we didn't really need anymore compost. Science and medicine aren't black and white.
Two thoughts, there are a lot of people out there who claim to be scientists and aren't. Second, peer review is usually and thankfully pretty effective in weeding out the pretenders.
I would say, seek out peer-reviewed studies written by legitimate scientists who are experts in the subject matter being written about. You do that and you're off to a pretty good start in reading up on the subject that interests you.
