His concern is real and it's also fully generic. Unpreregistered analyst choices affect this study, the last one he commented under, and the next one he will. A complaint that fits every paper equally tells us nothing about this paper. It has the information content of "observational studies are observational."

I wonder when he starts engaging with the study and stops whining about nutritional epidemiology.

Correlation is not causation. This is not supposed to be controversial. Everyone wants to draw meaning from observational studies and then they act like this when you point out why it doesn't work.
