I thought it was fairly convincing although I wish they’d go ahead and extend the mortality numbers out a bit so they’d be in terms I could wrap my head around more easily. It looks like Hazard Ratio is the chance someone would die during the study period, but what does that mean in practical terms? Maybe something like life expectancy would tie it all together? Maybe I’m just slow.
I also wonder like @Rarebear how accurate backing out certain portions can really be. Those who eat lots of red meat probably fall into a few groups beyond what was outlined in the study. Red meat is a big part of certain lifestyles which go beyond the factors they backed out.
To me, the degree they found red meat to contribute was most convincing, but again I’m having trouble with the “units” here.
Will I give up red meat because of it? No. I’ve tried a lot of various additions and subtractions from my diet, what I have now seems to make me feel the best. If that changes I’ll try something different. I think everyone should do the same and do what works for them.
I will however try to find some alternatives to the bacon/salami I generally use in sandwiches and tacos though. It’s just there for a little salty variety and if there’s something easier on my system that can serve the same purpose, all the better.
I also tried to dig a bit to find why processed meats were more damaging. My thought was they’d have a higher fat content but that doesn’t seem to be what the study found…
Unprocessed and processed meats contain similar amounts of saturated fat and heme iron; however, other constituents in processed meat, particularly sodium and nitrites, might explain the additional harm of processed meats.
The high sodium content may increase CVD risk through its effect on blood pressure. Nitrites and nitrates are frequently used in the preservation of processed meats, and blood nitrite concentrations have been related to endothelial dysfunction and impaired insulin response in adults.
I think we also tend to season our red meats more than others, so I wonder how much of the effect seen is actually the red meat and how much is just how we like it prepared? Processed meat generally have the “flavor” already in. It might be interesting although I have no idea how you’d study it directly.
