poorer health ≠ don't live as long
The healthy work effect (or healthy user bias) would only work as a counterargument if the study found no difference. Since it did find a difference, finding that the vegans lived longer, the healthy user bias would suggest that the difference was underestimated.
The other factors don't have to be controlled for unless I want to suggest that veganism causes [lower] mortality.
The only real problem is that participants didn't update their dietary status throughout the study. The vegan and vegetarians could have gone back to meat during the study. But I doubt that very many of them did.
