Given that the experts in the field are precisely those learning from and producing that same literature, the fact that the literature is generally low-quality doesn’t make me more inclined to trust them.
In terms of statistics and data, yes, the papers they produce are fairly low-quality. In terms of domain-specific knowledge, however, I’d trust an expert over pretty much anyone else. That being said, I do agree with you here:
It does make it exceptionally hard to gain a good understanding of the field yourself, though. Unlike Lumifer, I’d say the correct move, unless you are yourself a nutritionist or a fitness nerd or otherwise inclined to spend a large portion of your life on this, is to reserve judgment.
Although I prefer trusting expert authority to making my own judgments on unfamiliar topics, gaining a good-enough understanding to figure out which experts to trust is still hard, especially with so many conflicting conclusions out there. This being the case, the strategy you propose—reserve judgment—is precisely what I do.

That doesn’t help you when experts disagree.
