The premise of the new Nature Medicine study is that that red meat consumption is linked to heart disease risk. But this is not true.
First, all the “research” supposedly linking meat and meat products with heart disease are weak association studies.
Next, this 2010 Harvard review study reported:
Red meat intake was not associated with CHD (n=4 studies; relative risk per 100-g serving per day=1.00; 95% confidence interval, 0.81 to 1.23; P for heterogeneity=0.36) or diabetes mellitus (n=5; relative risk=1.16; 95% confidence interval, 0.92 to 1.46; P=0.25).
While it may be true that meat-eaters may have higher levels of “proatherogenic” compounds (as per the new study), this is a far cry from evidence, much less proof, that meat consumption causes heart disease.
Also keep in mind that atherosclerosis (and, hence, heart disease) is an entirely natural and as yet unexplained phenomenon.
