There’s an excellent discussion of the most recent RCT on UPF foods with its author here (https://sigmanutrition.com/episode577/).

Not only is the study itself very interesting, but it does a great job going over the evidence landscape on UPFs and food at the current point in time.

Dr Dicken is very clear that at the moment, in his view, they have insufficient evidence to make policy decisions like this, a view that has been echoed by pretty much all academic institutions when they’ve helped inform recent dietary guidelines.

Making big sweeping moves based on flimsy evidence is a good way to make people wary of following dietary guidance at all. After all, what’s the point of listening to “the science” if they turn around in 5 years and say “whoops, turns out we were wrong”?

This is a misstep IMO.
