I think your distrust in nutrition studies might stem from the fact there are nefarious entities publishing things. Various industries have a financial interest in making it look like their product, because it contains substance X, is beneficial to people. So they can design the most flimsy experiment with no pre-registration, and re-run it numerous times until they get the result they want.
Lots of conclusions from nutrition studies (especially meta analyses) are robust and useful to follow.
Consider the NutritionFacts website as a good starting point: a non-profit which has no ads, no industry "partners", etc - focused on distilling well-designed studies to see what everyday people can use from them.

I was not even considering the issue of bad actors. Simply that longitudinal, multi-variate studies of sufficient scale are essentially impossible to conduct.
Even though nutrition is one of the very oldest, and perhaps the very oldest, fields of human study, it still remains in the “butterfly collecting” phase of development as a science. It’s very very hard. I’m glad some people try.
Nutrition studies are more like phrenology in that they are so hard to do with so many confounding factors that you can’t really trust any macro conclusion.
