Well, hopefully we can keep up with the help of some uncorrupted public health experts who can read the studies, commission studies and meta-studies etc.

It helps that other countries have them too. It's hard to corrupt the entire world. I wouldn't worry (yet) about individual studies claiming some possible interaction, especially if they bunch up manky things (say, aim to study all emulsifiers at once, or all processing at once).

I would worry if, say, an additive was banned in many countries. And there's much that we know is bad, which is permitted for cultural reasons, and which therefore many people assume can't be that bad (smoked food in particular).
