Results state:

After multivariate adjustment, a high consumption of red meat was related to higher all-cause mortality (HR=1.14, 95% CI 1.01-1.28, 160+ vs. 10-19.9 g/day), and the association was stronger for processed meat (HR=1.44, 95% CI 1.24-1.66, 160+ vs. 10-19.9 g/day). After correction for measurement error, higher all-cause mortality remained significant only for processed meat (HR=1.18, 95% CI 1.11-1.25, per 50 g/d). We estimated that 3.3% (95% CI 1.5-5.0%) of deaths could be prevented if all participants had a processed meat consumption of less than 20 g per day. Significant associations with processed meat intake were observed for cardiovascular diseases, cancer, and 'other causes of death'. The consumption of poultry was not related to all-cause mortality.

Now I'll grant that "processed meat" is not particularly Paleo, but I know that many here love their bacon.

In general I think this supports Paleo - processed meat isn't natural, but found it interesting/concerning that they broad-brush "meat" and "processed meat" nearly together for a lot of the results.

Whilst you're adding the salt make sure your will is in order.

So the same study says eat more meat and you'll die, but eat no meat and you'll die. How do these people still have jobs?

The broad-brushing of "meat" and "processed meat" together is particularly insidious, because agenda-driven asshats, such as one editor at the LA times, barf out headlines like "Another study finds association between red meat and disease." They get called out in the comments, as usual, but the propaganda remains for the headline-obsessed public.

Per usual, stuff like this makes me wary of such studies (taken from the paper):

"We cannot exclude residual confounding, in particular due to incomplete adjustment for active and passive smoking. The sub-group analysis for processed meat showed heterogeneity according to smoking, with significant associations only in former and current smokers and no significant associations in never smokers, which is compatible with residual confounding by smoking"

and:

"Men and women in the top categories of red or processed meat intake in general consumed fewer fruits and vegetables than those with low intake. They were more likely to be current smokers and less likely to have a university degree (Table 1). Men with high red meat consumption consumed more alcohol than men with a low consumption".

Also, an interesting quote from the paper:

"In the calibrated spline models, we observed significantly higher all-cause mortality with higher consumption of processed meat and no statistically significant association with red meat or poultry intake (Figure 1). However, all-cause mortality was higher among participants with very low or no red meat consumption"

Ultimately, I take these studies with a grain of salt. Mmmm salty meat. Time for lunch.
