And there's not nearly enough evidence to establish the causal links that you are so certain of. I get that it "makes sense" to you. It fits in with your worldview. But that's not how science works.
"Studies have shown" is the classic hint that "this person has no clue that they're talking about".
Show me specific reproduced experimental studies with proper controls, talk about effect size, and then there would be no argument. Such proof has failed to arise for countless health trends in the past, no matter how intuitive they may have been.
