How much have you looked into potential confounders for these things? With the processed meat thing in particular, I've wondered what could be so bad about processing meat, and if this could be one of those things where education and wealth are correlated with health, so if wealthy, well-educated people start doing something, it becomes correlated with health too. In that particular case, it would be a case of processed meat being cheap, and therefore eaten by poor people more, while steak tends to be expensive.

(This may be totally wrong, but it seems like an important concern to have investigated.)

My process is to collect a list of confounders by looking at things controlled for in different studies, and then downgrading my estimation of evidence strength if I see obvious ones from the list not mentioned in a study. This is probably not the best way to do this but I haven't come up with anything better yet.
