It's a field where actual long term controlled experiments are impossible, confounding variables are everywhere, and multiple lobbies have vested interests in the outcomes.
I take everything with a grain of salt apart from studies of harm when sources are credible and numerous and even then, I'm not fully confident.
The only current advice I follow is avoiding industrially processed food. That sounds like a sound one as this kind of food is basically terra incognita. It's just applying the precaution principle.

I think avoiding industrially processed food is wise, but it eliminates 99% of restaurant food and 90% of prepared food in almost any setting, only exception being about half the stuff at a salad bar.
Almost everything that isn't a single ingredient whole plant or animal food contains industrially processed oil or sweetener/starch.
Still worth doing imho but I understand why it's not easy for most people.

It is also surprisingly hard in practice. There are so many foods that on the label are supposed to be whole foods or low processed but then when you read the ingredients do you realize you've been bamboozeld.
This is a complete myth. Human populations are not homogenous, gene pools that relied on agriculture for the last 10k years are completely different than hunter gatherer populations. You have been lied to
A casual look at where people live the oldest will tell you about statistical outliers and bad government recordkeeping.
